Description

夾持工具Clamping tool

本發明係關於一種夾持工具，其包含一對臂部，臂部具有藉由連結部連結的顎部與手柄。The present invention relates to a gripping tool comprising a pair of arms having an ankle and a handle joined by a joint.

作為習知技術，現已揭露一種夾持工具，其係為：在兩臂部的各顎部的對向面的前部形成有橫夾齒，在兩臂部之間設有止動件，止動件用以在將握柄握入操作時限制兩臂部的顎部的握入限度，橫夾齒由山谷狀地連續的多個橫肋齒構成，橫肋齒延伸在交叉於沿著前後方向的工具中心軸的方向，止動件設在除了前方區域以外的部分，前方區域比位在兩顎部最末端的橫肋齒還靠前方，設在一顎部的橫肋齒與設在另一顎部的橫肋齒以在前後位置錯開的狀態配置，在藉由止動件將兩臂部握入操作到握入限度為止的閉合姿勢中，一顎部的橫肋齒的山部以如後述的方式構成：進入另一顎部的橫肋齒的谷部內，且包含橫肋齒的兩顎部的前方區域彼此呈不接觸的正對姿勢（例如參照專利文獻1）。As a prior art, a gripping tool has been disclosed in which a transverse pinion is formed at a front portion of an opposing surface of each of the arm portions of the two arms, and a stopper is provided between the arm portions. The stopper is configured to limit the gripping limit of the crotch portion of the two arms when the grip is gripped, and the lateral pin is formed by a plurality of transverse rib teeth continuous in the valley shape, and the transverse rib teeth extend along the crossing In the direction of the center axis of the tool in the front-rear direction, the stopper is provided in a portion other than the front region, and the front region is located forward of the transverse rib teeth located at the end of the two jaws, and the transverse rib teeth of the ankle portion are disposed. The transverse rib teeth provided on the other crotch portion are disposed in a state in which the front and rear positions are shifted, and in the closed posture in which the arms are gripped by the stopper to the gripping limit, the transverse rib teeth of one crotch portion The mountain portion is configured to have a posture in which the front region of the two ridge portions of the lateral rib teeth is not in contact with each other (see, for example, Patent Document 1).

在如上述的習知技術中，在握入握柄時，藉由止動件限制握入限度，使包含橫肋齒的兩顎部的前方區域彼此不接觸，而防止因設在兩顎部的橫夾齒彼此接觸所導致的劣化（例如磨耗等的劣化或位置錯開等的劣化等），能防止工具的劣化。又，在藉由止動件將兩臂部握入操作到握入限度為止的閉合姿勢中，一顎部的橫肋齒的山部因為進入另一顎部的橫肋齒的谷部內，所以對於片材體等厚度為小的夾持對象，使對向的橫肋齒的山部的前端相互不同地抵接夾持對象的兩表面，而能穩固地夾住固定夾持對象。In the prior art as described above, when the grip is gripped, the gripping limit is restricted by the stopper, so that the front regions of the two crotch portions including the lateral rib teeth are not in contact with each other, and are prevented from being disposed on the two crotch portions. Deterioration due to contact between the lateral nips (for example, deterioration of abrasion or the like, deterioration of position, etc.) can prevent deterioration of the tool. Further, in the closed posture in which the arm portions are gripped by the stopper to the gripping limit, the mountain portion of the lateral rib teeth of one turn portion enters the valley portion of the lateral rib teeth of the other crotch portion, so that In the case of a small object having a small thickness such as a sheet body, the front ends of the mountain portions of the opposing lateral rib teeth are brought into contact with each other differently from each other, and the fixed holding object can be firmly held.

[習知技術文獻] [專利文獻] [專利文獻1]日本特開2016-120582號公報（第1頁、第1圖等）。[Patent Document] [Patent Document 1] JP-A-2016-120582 (first page, first figure, etc.).

[發明所欲解決的課題] 然而，在習知的夾持工具中，因為藉由設在比顎部的橫夾齒還後方的止動件進行限制握入限度，使包含橫肋齒的兩顎部的前方區域彼此呈不接觸，所以在藉由止動件將兩臂部握入操作到握入限度為止而閉合兩顎部的狀態，即使在比止動件還前端側的兩顎部的前端附近，於對向面間亦產生間隙，而無法以夾持工具的前端附近夾持厚度比此間隙還薄的夾持對象（例如薄的片材等）。因此，在無法將夾持對象配置在以橫夾齒可夾入的位置的情況，係無法夾住夾持對象。像這樣，在習知的保持工具中，具有無法適宜地夾持厚度為薄的夾持對象的課題。[Problem to be Solved by the Invention] However, in the conventional gripping tool, since the retaining limit is restricted by the stopper provided behind the lateral teeth of the weir portion, two teeth including the transverse rib teeth are provided. Since the front regions of the crotch portions are not in contact with each other, the state in which the two crotch portions are closed by the two arm portions being gripped by the stopper to the gripping limit, even at the crotch portion on the distal end side of the stopper In the vicinity of the front end, a gap is also formed between the opposing faces, and it is not possible to sandwich a holding object (for example, a thin sheet or the like) having a thickness thinner than the gap near the front end of the holding tool. Therefore, in the case where the clamp object cannot be placed at a position where the horizontal pinch can be pinched, the clamp object cannot be clamped. As described above, in the conventional holding tool, there is a problem that the holding target having a small thickness cannot be appropriately sandwiched.

本發明為用以解決如上述的課題者，目的在於提供一種夾持工具，能防止劣化且能適宜地夾持厚度為薄的夾持對象。The present invention has been made to solve the problems as described above, and an object of the invention is to provide a holding tool capable of preventing deterioration and capable of appropriately sandwiching a nip object having a small thickness.

如圖2所示，鉗子100包含：第一臂部1a與第二臂部1b，為一對的臂部1；以及連結部3，自由相對轉動地連結該第一臂部1a與第二臂部1b。第一臂部1a與第二臂部1b分別在前端側具有顎部4，且在後端側具有手柄2。再者，在未區別第一臂部1a與第二臂部1b的情況，以下單純稱為臂部1的情況。又，還有將一對臂部1稱為兩臂部1的情況。又，還有將設在一對臂部1的顎部4合併稱為兩顎部4的情況。連結部3連結X字狀地配置的第一臂部1a與第二臂部1b。連結部3由突起部3a與連結軸3b構成；其中，突起部3a設在第一臂部1a與第二臂部1b的顎部4的基端。各突起部3a具有插通孔3c，在以各插通孔3c的中心軸一致的方式X字狀地配置第一臂部1a與第二臂部1b的狀態，藉由連結軸3b嵌合第一臂部1a與第二臂部1b的突起部3a的插通孔3c，使第一臂部1a與第二臂部1b被連結。連結軸3b例如是固定在第一臂部1a，且藉由第二臂部1b的突起部3a而自由相對轉動地軸支撐臂部1，惟連結軸3b亦可固定在兩臂部1任一者。As shown in FIG. 2, the forceps 100 includes a first arm portion 1a and a second arm portion 1b, which are a pair of arm portions 1, and a coupling portion 3 that rotatably couples the first arm portion 1a and the second arm. Part 1b. The first arm portion 1a and the second arm portion 1b have a crotch portion 4 on the front end side and a handle 2 on the rear end side, respectively. In the case where the first arm portion 1a and the second arm portion 1b are not distinguished, the following is simply referred to as the arm portion 1. Further, there is a case where the pair of arm portions 1 is referred to as the both arm portions 1. Further, the case where the crotch portions 4 provided in the pair of arm portions 1 are collectively referred to as the crotch portion 4 is also known. The connecting portion 3 connects the first arm portion 1a and the second arm portion 1b that are arranged in an X shape. The connecting portion 3 is composed of a protruding portion 3a and a connecting shaft 3b. The protruding portion 3a is provided at the base end of the first arm portion 1a and the crotch portion 4 of the second arm portion 1b. Each of the projections 3a has an insertion hole 3c, and the first arm portion 1a and the second arm portion 1b are arranged in an X shape so that the central axes of the insertion holes 3c coincide with each other, and the coupling shaft 3b is fitted. The insertion portion 3a of the one arm portion 1a and the second arm portion 1b is connected to the first arm portion 1a and the second arm portion 1b. The connecting shaft 3b is fixed to the first arm portion 1a, for example, and the arm portion 1 is rotatably supported by the protruding portion 3a of the second arm portion 1b. However, the connecting shaft 3b may be fixed to either of the arms 1b. .

再者，於此列舉連結部3由突起部3a與連結軸3b構成的情況為例，惟連結部3亦可為上述以外的構成。又，本發明並不限制設置連結部3的位置。於此，列舉如後述的情況為例：第一臂部1a與第二臂部1b在連結軸3b的中心軸的中心是具有相對於工具中心軸8呈對稱的形狀；其中，連結軸3b的中心軸為通過連結軸3b的中心軸的長軸方向中心的軸，工具中心軸8為垂直地相交此中心軸的軸。但是，亦可不對稱。Here, the case where the connection portion 3 is constituted by the protrusion portion 3a and the connection shaft 3b is exemplified, but the connection portion 3 may have a configuration other than the above. Further, the present invention does not limit the position at which the joint portion 3 is provided. Here, as will be described later, the first arm portion 1a and the second arm portion 1b have a shape symmetrical with respect to the tool center axis 8 at the center of the central axis of the connecting shaft 3b; wherein the shaft 3b is coupled The central axis is an axis passing through the center of the long axis direction of the central axis of the connecting shaft 3b, and the tool central axis 8 is an axis perpendicularly intersecting the central axis. However, it can also be asymmetrical.

臂部1的材質一般為金屬，惟只要是可利用作為鉗子的材質則其他材質亦可。於此，列舉臂部1是鍛造品的情況為例說明。The material of the arm portion 1 is generally metal, but other materials may be used as long as the material can be used as a forceps. Here, a case where the arm portion 1 is a forged product will be described as an example.

兩臂部1的各顎部4的對向面14如圖4等所示，具有第一區域5與第二區域6。對向面14例如是夾持夾持對象的面。 第一區域5為如後述的區域：位在兩臂部1的各顎部4的對向面14的前端側。第一區域5為各顎部4的對向面14中位在最前端側的區域。第一區域5例如可為接觸各顎部4的前端21的區域。於此，前端21可想成是位在顎部4的前端的面。兩臂部1的各顎部4的第一區域5為在閉合兩顎部4的狀態會接觸的區域。閉合兩顎部4例如是：握住第一臂部1a的手柄2與第二臂部1b的手柄2，使兩顎部4間的間隔最為縮小，或使兩顎部4的抵接面彼此最為接近。以第一區域5接觸的方式閉合兩顎部4的狀態例如可想成是將第一臂部1a的手柄2與第二臂部1b的手柄2握住到握入限度為止的狀態，亦可想成是令鉗子100為閉合姿勢的狀態。第一區域5例如較佳為從顎部4的前端朝向前後方向10mm以內的區域。但是，此較佳距離可因鉗子100的大小而不同。The opposing surface 14 of each of the crotch portions 4 of the both arm portions 1 has a first region 5 and a second region 6 as shown in FIG. 4 and the like. The opposing surface 14 is, for example, a surface on which a gripping object is held. The first region 5 is a region to be described later: it is located on the front end side of the opposing surface 14 of each of the crotch portions 4 of the both arm portions 1. The first region 5 is a region on the most distal end side of the opposing surface 14 of each of the jaw portions 4. The first region 5 may be, for example, a region that contacts the front end 21 of each of the jaws 4. Here, the front end 21 can be thought of as a surface located at the front end of the crotch portion 4. The first region 5 of each of the crotch portions 4 of the both arm portions 1 is a region that comes into contact with the two crotch portions 4 in a closed state. The closing two jaws 4 are, for example, holding the handle 2 of the first arm portion 1a and the handle 2 of the second arm portion 1b, so that the interval between the two jaw portions 4 is minimized, or the abutting faces of the two jaw portions 4 are mutually The closest. The state in which the two crotch portions 4 are closed in such a manner that the first region 5 is in contact with each other can be thought of, for example, a state in which the handle 2 of the first arm portion 1a and the handle 2 of the second arm portion 1b are gripped to the gripping limit. It is thought that the pliers 100 is in a closed posture. The first region 5 is preferably, for example, a region within 10 mm from the front end of the crotch portion 4 toward the front-rear direction. However, this preferred distance may vary depending on the size of the forceps 100.

第一區域5接觸為兩顎部4的第一區域5彼此接觸，換言之，亦即一顎部4的第一區域5接觸另一顎部4的第一區域5。第一區域5在閉合兩顎部4的狀態，只要為第一區域5的整體或至少一部分接觸即可。第一區域5彼此可用面作接觸，亦可用線作接觸，亦可用點作接觸，惟較佳是用面作接觸。兩顎部4具有的第一區域5較佳為：對向的面彼此在閉合兩顎部4的狀態為相互地接觸；其中，對向的面設在第一區域5的至少一部分。面彼此的接觸較佳為面彼此的密接。於此，面一般為平面。第一區域5的接觸例如是第一區域5具有的平面彼此的接觸。舉例而言，第一區域5的接觸較佳為第一區域5具有的全部平面彼此的接觸，惟部分的平面彼此的接觸亦可。於此，平面例如是如後述的平面：位在具有連結軸3b的中心軸的平面上。第一區域5具有的全部平面例如是設在如後述區域的平面：從第一區域5除去後述凹部16設置的區域後的區域。再者，於此的平面彼此的接觸即使在因誤差等的錯開或平面的微小凹凸等所導致部分不接觸的情況，亦可想成是平面彼此為接觸。The first region 5 is in contact with the first region 5 of the two jaws 4, in other words, that is, the first region 5 of one of the jaws 4 contacts the first region 5 of the other of the jaws 4. The first region 5 is in a state of closing the two crotch portions 4 as long as it is in contact with the entirety or at least a portion of the first region 5. The first regions 5 are in contact with each other by a surface, and may be contacted by a wire or by a contact, but it is preferable to use a surface for contact. Preferably, the first region 5 of the two jaw portions 4 is such that the opposing faces are in contact with each other in a state in which the two jaw portions 4 are closed; wherein the opposing faces are provided in at least a portion of the first region 5. The contact of the faces with each other is preferably a close contact of the faces. Here, the surface is generally flat. The contact of the first region 5 is, for example, the contact of the planes of the first region 5 with each other. For example, the contact of the first region 5 is preferably such that all of the planes of the first region 5 are in contact with each other, but only a part of the planes are in contact with each other. Here, the plane is, for example, a plane as will be described later: it is located on a plane having a central axis of the connecting shaft 3b. The entire plane of the first region 5 is, for example, a plane provided in a region as described later: a region in which the region of the recess portion 16 to be described later is removed from the first region 5. Further, even if the contact between the planes is not in contact with each other due to a shift in error or the like, or a slight unevenness in the plane, it is considered that the planes are in contact with each other.

於此，兩顎部4的各第一區域5中相對於前後方向而設在兩側的平面5a彼此係令為在閉合兩顎部4的狀態會接觸者。前後方向為從臂部1的後端側朝向前端側的方向，或為從前端側朝向後端側的方向。再者，可將上述工具中心軸8的延伸方向想成是前後方向。在閉合兩顎部4的狀態，一顎部4的第一區域5的平面5a接觸設在相對於該平面5a而對向的位置的另一顎部4的第一區域5的平面5a。再者，可將包含如後述者的區域想成是第一區域5：在閉合兩顎部4的狀態會接觸的部分與不接觸的部分兩者，但亦可只將設有在閉合顎部的狀態會接觸的部分（例如平面5a等的面）的區域想成是第一區域，而不接觸的區域（例如後述設有凹部16的區域等）則不想成是第一區域；其中，設有會接觸的部分的區域為如後述的區域：位在兩臂部1的各顎部4的對向面14的前端側的區域。Here, the planes 5a provided on both sides of the first region 5 of the two jaw portions 4 with respect to the front-rear direction are mutually contacted in a state in which the two jaw portions 4 are closed. The front-rear direction is a direction from the rear end side of the arm portion 1 toward the front end side, or a direction from the front end side toward the rear end side. Further, the extending direction of the tool center shaft 8 can be considered to be the front-rear direction. In a state in which the two crotch portions 4 are closed, the plane 5a of the first region 5 of one crotch portion 4 contacts the plane 5a of the first region 5 of the other crotch portion 4 provided at a position opposed to the plane 5a. Further, the area including the latter will be considered to be the first area 5: both the portion that is in contact with the state in which the two jaw portions 4 are closed and the portion that is not in contact, but may be provided only in the closed portion The area in which the state is in contact (for example, the surface of the plane 5a or the like) is intended to be the first area, and the area that is not in contact (for example, the area in which the recess 16 is provided later) is not intended to be the first area; The area where the portion to be in contact is a region as will be described later: a region on the distal end side of the opposing surface 14 of each of the crotch portions 4 of the both arm portions 1.

再者，此兩顎部4的第一區域5中在閉合兩顎部4的狀態會接觸的部分可想成是發揮如後述的止動件功能：在握住手柄2的情況藉由前端接觸，而定出第一臂部1a與第二臂部1b的握入限度。舉例而言，在本實施形態的鉗子100中，如後述的平面5a藉由在握入限度下接觸（例如密接），成為無法再進一步握入：平面5a設在兩顎部4的第一區域5的對向位置。Further, the portion of the first region 5 of the two jaw portions 4 which is in contact with each other in the state in which the two jaw portions 4 are closed can be thought of as a function of a stopper as will be described later: by the front end contact when the handle 2 is held The grip limit of the first arm portion 1a and the second arm portion 1b is determined. For example, in the forceps 100 of the present embodiment, the plane 5a to be described later is contacted (for example, in close contact) by the gripping limit, so that it can no longer be further gripped: the plane 5a is provided in the first region 5 of the two jaws 4 The opposite position.

第二區域6為如後述的區域：兩臂部1的各顎部4的對向面14中位在比第一區域5後方。於此，雖列舉第二區域6設於在前後方向中成為緊接第一區域5後方的位置的情況，亦可為不位在緊接於後方的位置。The second region 6 is a region as will be described later: the opposing surface 14 of each of the crotch portions 4 of the both arm portions 1 is located rearward of the first region 5 . Here, the second region 6 is provided in a position immediately after the first region 5 in the front-rear direction, and may not be located immediately behind.

兩臂部1的各顎部4的第二區域6為形成有橫夾齒11的區域。橫夾齒11具有設在各顎部4的對向面14的多個凸條111與凹條112。此凹條112例如鄰接凸條111。此凹條112例如可為形成在相鄰排列的凸條111間的凹條。橫夾齒11具有排列在前後方向的多個凸條111與凹條112。凸條111彼此與凹條112彼此於此為平行地排列在前後方向。但是，亦可為不平行地配置。於此，橫例如是在平行於對向面14的面內相對於鉗子100的前後方向成為垂直的方向。於此，橫方向可想成是對向面14或鉗子100的寬度方向。各凸條111與各凹條112於此係直線狀地延伸在相對於前後方向垂直的方向。垂直於前後方向的方向例如可想成是顎部4的對向面14的寬度方向等。橫夾齒11例如具有在前後方向山谷狀地連續而配置的多個凸條111與凹條112。舉例而言，在橫夾齒11中，凸條111與凹條112為在前後方向交互地排列。橫夾齒11例如構成為在前後方向排列的多個山谷狀。橫夾齒11可想成是延伸在相對於前後方向垂直的方向且山谷狀地連續的橫肋齒。於此，相對於前後方向垂直的方向例如可想成是相對於如後述的工具中心軸8垂直的方向：延伸在圖2所示的鉗子100的前後方向。但是，凸條111與凹條112可延伸在相對於前後方向垂直的方向，亦可不延伸在垂直方向。又，凸條111與凹條112的延伸形狀可為直線狀，亦可為非直線狀。The second region 6 of each of the crotch portions 4 of the both arm portions 1 is a region in which the lateral teeth 11 are formed. The lateral nip 11 has a plurality of ribs 111 and recesses 112 provided on the opposing faces 14 of the respective dam portions 4. This concave strip 112 abuts, for example, the rib 111. This concave strip 112 may be, for example, a concave strip formed between adjacently arranged ribs 111. The lateral nip 11 has a plurality of ribs 111 and concave strips 112 arranged in the front-rear direction. The ridges 111 and the concave strips 112 are arranged in parallel with each other in the front-rear direction. However, it may be configured not to be parallel. Here, the horizontal direction is, for example, a direction perpendicular to the front-rear direction of the forceps 100 in a plane parallel to the opposing surface 14 . Here, the lateral direction is conceivable as the width direction of the opposing surface 14 or the forceps 100. Each of the ridges 111 and each of the concave strips 112 linearly extends in a direction perpendicular to the front-rear direction. The direction perpendicular to the front-rear direction can be thought of, for example, the width direction of the opposing surface 14 of the crotch portion 4 or the like. The lateral nip 11 has, for example, a plurality of ridges 111 and concave strips 112 which are arranged continuously in the valley shape in the front-rear direction. For example, in the lateral teeth 11, the ribs 111 and the concave strips 112 are alternately arranged in the front-rear direction. The lateral teeth 11 are configured, for example, in a plurality of valley shapes arranged in the front-rear direction. The lateral teeth 11 can be thought of as transverse rib teeth that extend in a direction perpendicular to the front-rear direction and are continuous in a valley shape. Here, the direction perpendicular to the front-rear direction can be considered, for example, in a direction perpendicular to the tool center axis 8 to be described later, extending in the front-rear direction of the forceps 100 shown in FIG. 2 . However, the ridges 111 and the concave strips 112 may extend in a direction perpendicular to the front-rear direction or may not extend in the vertical direction. Moreover, the extending shape of the ridges 111 and the concave strips 112 may be linear or non-linear.

第二區域6例如為如後述的區域：在前後方向中，於從前端到後端的全部範圍設有橫夾齒11。舉例而言，第二區域6可為位在第一區域5後方的區域，亦即可為在全區域設有橫夾齒11的區域。但是，第二區域6在寬度方向中可包含不設有橫夾齒11的區域。舉例而言，第二區域6為位在第一區域5後方的區域，亦即可為如後述的區域：在朝向前後方向而成為兩側的區域的全區域設有橫夾齒。在本實施形態中，如圖4與圖5所示，橫夾齒11列舉如後述者為例：設在朝向對向面14的前後方向而成為兩側的位置。在圖5中，以斜線表示的部分為表示兩顎部4的凸條111中由距離兩顎部4的對向面14為等距離的平面所產生的剖面，且第一臂部1a的凸條111的剖面與第二臂部1b的凸條111的剖面，在前後方向交互地排列。再者，可將前端與後端位在與設在第一區域5後方的橫夾齒11的前端與後端在前後方向中的位置成為相同位置的顎部4的對向面14的區域想成是第二區域6。The second region 6 is, for example, a region as will be described later: in the front-rear direction, the lateral teeth 11 are provided over the entire range from the front end to the rear end. For example, the second region 6 may be an area located behind the first region 5, that is, an area in which the transverse teeth 11 are provided in the entire region. However, the second region 6 may include a region in which the lateral teeth 11 are not provided in the width direction. For example, the second region 6 is a region located behind the first region 5, and may be a region as will be described later: lateral teeth are provided in the entire region which is a region on both sides in the front-rear direction. In the present embodiment, as shown in FIG. 4 and FIG. 5, the lateral teeth 11 are exemplified as follows, and are provided at positions on both sides facing the front-rear direction of the opposing surface 14. In Fig. 5, a portion indicated by oblique lines is a cross section which is formed by a plane which is equidistant from the opposing faces 14 of the two jaw portions 4 of the ridges 111 of the two jaw portions 4, and the convex portion of the first arm portion 1a. The cross section of the strip 111 and the cross section of the ridge 111 of the second arm portion 1b are alternately arranged in the front-rear direction. Further, the front end and the rear end position may be in the area of the opposing surface 14 of the crotch portion 4 at the same position as the position of the front end and the rear end of the lateral nip 11 provided behind the first region 5 in the front-rear direction. It is the second area 6.

於此，列舉第一臂部1a的橫夾齒11具有的凸條111數量是8個、第二臂部1b的橫夾齒11具有的凸條數量是7個為例，惟本發明並不限制凸條111的數量。Here, the number of the ribs 111 of the first arm portion 1a is eight, and the number of the ribs 11 of the second arm portion 1b is seven, but the present invention does not Limit the number of ribs 111.

相對於構成一個橫夾齒11的各凸條111，在前後方向中鄰接的位置係形成有凹條112。凹條112與凸條111在前後方向交互地排列。各凹條112於此係直線狀地延伸在相對於前後方向垂直的方向。此凹條112的其中一部份可兼作鄰接的凸條111的一部分。舉例而言，凹條112為具有如後述側面的凹條：將鄰接凸條111的側面（例如斜面）作為連續在底端112a的側面。於此，側面為各凸條111中朝向凸條111延伸的方向而位在兩側的側面。凹條112例如是形成在相鄰的2個凸條111之間的凹條。舉例而言，凹條112例如是具有如後述斜面的凹條：將相鄰2個凸條111的對向的2個側面（例如斜面）作為連續在底端112a的2個對向的斜面。凸條111與凹條112的形狀並不限制。凸條111的突端111a可具有角，可為曲面，亦可為平坦面。又，凹條112的底端112a可具有角，可為曲面，亦可為平坦面。The concave strips 112 are formed at positions adjacent to each other in the front-rear direction with respect to the respective ribs 111 constituting one of the lateral teeth 11 . The concave strips 112 and the ribs 111 are alternately arranged in the front-rear direction. Each of the concave strips 112 extends linearly in a direction perpendicular to the front-rear direction. A portion of the recess 112 can double as part of the adjacent rib 111. For example, the concave strip 112 is a concave strip having a side surface as will be described later: a side surface (for example, a sloped surface) of the adjacent convex strip 111 is continuous on the side surface of the bottom end 112a. Here, the side faces are the side faces of the respective ribs 111 that are located on both sides in the direction in which the ribs 111 extend. The concave strip 112 is, for example, a concave strip formed between two adjacent ribs 111. For example, the concave strip 112 is, for example, a concave strip having a slope as will be described later: two side surfaces (for example, inclined surfaces) that face the two adjacent convex strips 111 are two inclined surfaces that are continuous on the bottom end 112a. The shape of the ridges 111 and the recesses 112 is not limited. The protruding end 111a of the ridge 111 may have an angle, may be a curved surface, or may be a flat surface. Moreover, the bottom end 112a of the concave strip 112 may have an angle, may be a curved surface, or may be a flat surface.

兩顎部4的橫夾齒11，係在以第一區域5接觸的方式閉合兩顎部4的狀態，一顎部4的橫夾齒11的凸條111進入鄰接另一顎部4的橫夾齒11的凸條111之凹條112內，且一顎部4的橫夾齒11的凸條111以不接觸另一顎部4的橫夾齒11的凹條112的方式構成。再者，橫夾齒11的凸條111可想成是橫夾齒的山部，凹條112可想成是谷部，在此情況，一顎部4的橫夾齒11的凸條111進入鄰接另一顎部4的橫夾齒11的凸條111之凹條112，亦可想成是，一顎部4橫夾齒11的山部進入鄰接另一顎部4的橫夾齒11的山部之谷部內。The lateral teeth 11 of the two jaws 4 are in a state in which the two jaws 4 are closed in such a manner that the first region 5 is in contact, and the ridges 111 of the lateral teeth 11 of one jaw 4 enter the transverse direction of the other jaws 4. The ribs 111 of the ribs 111 of the nipples 11 and the ribs 111 of the traverse teeth 11 of one of the ridges 11 are formed so as not to contact the recesses 112 of the lateral nips 11 of the other dam 4. Furthermore, the ridges 111 of the transverse nipples 11 can be thought of as the mountain portions of the transverse nips, and the concave strips 112 can be thought of as the valley portions. In this case, the ridges 111 of the transverse nipples 11 of the shank portion 4 enter. The concave strip 112 of the rib 111 adjacent to the lateral nip 11 of the other shank 4 is also conceivable, that the ridge portion 4 of the tang portion 4 crosses the mountain portion of the tooth 11 into the transverse nip 11 adjacent to the other shank portion 4. Inside the valley of the mountain.

舉例而言，鉗子100的第二區域6如圖1所示具有橫夾齒11，橫夾齒11在前方配置有以相同間距P1配置的相同高度的多個凸條111，於其後方則配置有間距比間距P1還寬且隨著配置位置往後方依序間距與高度變大的多個凸條111。於此，凸條111的高度可想成是凸條的丈高。各凸條111係：垂直於凸條111延伸的方向的剖面具有三角形狀，凸條111的突端111a與凹條112的底端112a被修圓，從凹條112的底端112a到鄰接的凸條111的突端111a的高度為0.6mm時，令突端111a的半徑為0.2mm，並令底端112a的半徑為0.3mm。再者，橫夾齒11的凸條111的突端111a可想成是橫夾齒11的山部的突端，橫夾齒11的凹條112的底端112a可想成是橫夾齒11的谷部的底端。For example, the second region 6 of the forceps 100 has lateral teeth 11 as shown in FIG. 1 , and the lateral teeth 11 are disposed with a plurality of ribs 111 of the same height disposed at the same pitch P1 in front, and are disposed at the rear side thereof. There are a plurality of ribs 111 having a pitch which is wider than the pitch P1 and which becomes larger in order from the arrangement position to the rear. Here, the height of the rib 111 can be thought of as the height of the ridge. Each of the ribs 111 has a triangular shape in a cross section perpendicular to the direction in which the ribs 111 extend, and the protruding end 111a of the rib 111 and the bottom end 112a of the concave strip 112 are rounded from the bottom end 112a of the concave strip 112 to the adjacent convex portion. When the height of the projecting end 111a of the strip 111 is 0.6 mm, the radius of the projecting end 111a is 0.2 mm, and the radius of the bottom end 112a is 0.3 mm. Further, the protruding end 111a of the ridge 111 of the lateral pin 11 can be thought of as the protruding end of the mountain portion of the lateral pin 11, and the bottom end 112a of the concave strip 112 of the lateral pin 11 can be thought of as a valley of the lateral pin 11 The bottom of the department.

在將橫夾齒11往朝向凸條111的延伸方向觀看的情況，第一臂部1a的顎部4的橫夾齒11與第二臂部1b的顎部4的橫夾齒11除了高度方向與前後方向位置不同之外，係具有大略相同的形狀。舉例而言，第二臂部1b的顎部4的橫夾齒11具有幾乎相同於如後述形狀的形狀：將第一臂部1a的顎部4的橫夾齒11相對於包含連結軸3b的中心軸的平面對稱地移動後的橫夾齒11在前後方向錯開。In the case where the lateral nip 11 is viewed toward the extending direction of the ridge 111, the lateral nip 11 of the crotch portion 4 of the first arm portion 1a and the lateral nip 11 of the crotch portion 4 of the second arm portion 1b are apart from the height direction. The shape has a substantially the same shape as the position in the front-rear direction. For example, the lateral pin 11 of the crotch portion 4 of the second arm portion 1b has a shape almost the same as that described later: the lateral pin 11 of the crotch portion 4 of the first arm portion 1a is opposed to the coupling shaft 3b. The lateral teeth 11 whose planes of the central axis are symmetrically moved are shifted in the front-rear direction.

以相同於第一臂部1a的橫夾齒11前方的間距P1排列的多個凸條111，與以相同於第二臂部1b的橫夾齒11前方的間距P1排列的多個凸條111，在以第一區域5接觸的方式閉合兩顎部4的狀態，如圖1所示，以在前後方向位置只錯開此間距的一半間距量而設置。同樣地，第一臂部1a的橫夾齒11內後方的多個凸條111，與第二臂部1b的橫夾齒11內後方的多個凸條111，在以第一區域5接觸的方式閉合兩顎部4的狀態，如圖1所示，以在前後方向位置只錯開彼此的一半間距量而設置。The plurality of ribs 111 arranged in the same manner as the pitch P1 in front of the lateral teeth 11 of the first arm portion 1a and the plurality of ribs 111 arranged in the same distance P1 from the front of the lateral teeth 11 of the second arm portion 1b The state in which the two crotch portions 4 are closed in such a manner as to contact with the first region 5 is set as shown in Fig. 1, by shifting only half the pitch of the pitch in the front-rear direction. Similarly, the plurality of ribs 111 on the inner side of the lateral teeth 11 of the first arm portion 1a and the plurality of ribs 111 on the inner side of the lateral teeth 11 of the second arm portion 1b are in contact with each other in the first region 5. The state in which the two jaw portions 4 are closed as shown in FIG. 1 is set so as to be shifted by only half the amount of the mutual spacing in the front-rear direction.

藉此，在以第一區域5接觸的方式閉合兩顎部4的狀態，能將一顎部4的橫夾齒11的凸條111進入另一顎部4的橫夾齒11的凹條112內。又，於此，藉由如上述將間距只錯開一半間距量，在以第一區域5接觸的方式閉合兩顎部4的狀態，一顎部4的橫夾齒11的凸條111的突端111a，與另一顎部4的橫夾齒11的凹條112的底端112a，在凸條111的高度方向能正對。藉由像這樣的正對，以對向的橫夾齒11間夾住片材等的夾持對象時，減低凸條111的突端111a抵接位置的分布的偏差，而能適宜地分散夾住力，減少賦予夾持對象的傷害。但是，亦可對應所需，使一顎部4的橫夾齒11的凸條111的突端111a，與另一顎部4的橫夾齒11的凹條112的底端112a，在凸條111的高度方向不正對。Thereby, in a state in which the two crotch portions 4 are closed in such a manner that the first region 5 is in contact, the ridges 111 of the lateral nip 11 of one shank portion 4 can be introduced into the concave strip 112 of the lateral nip 11 of the other crotch portion 4. Inside. Further, here, by folding the pitch by only half the pitch as described above, the two ends 4 are closed in such a manner that the first region 5 is in contact with each other, and the protruding end 111a of the ridge 111 of the lateral pin 11 of the one portion 4 is formed. The bottom end 112a of the concave strip 112 of the lateral pin 11 of the other crotch portion 4 can be aligned in the height direction of the rib 111. When the object to be sandwiched between the opposing lateral teeth 11 is sandwiched between the opposing lateral teeth 11 as described above, the variation in the distribution of the abutment positions of the protruding ends 111a of the ridges 111 is reduced, and the clamping can be appropriately dispersed. Force to reduce damage to the gripping object. However, the protruding end 111a of the rib 111 of the lateral nip 11 of one shank 4 and the bottom end 112a of the concave strip 112 of the lateral nip 11 of the other shank 4 may be correspondingly required in the ridge 111. The height direction is not correct.

又，兩顎部4的橫夾齒11係：在以第一區域5接觸的方式閉合兩顎部4的狀態，一顎部4的橫夾齒11的凸條111以不接觸另一顎部4的橫夾齒11的凹條112內的方式構成。再者，兩顎部4的橫夾齒11較佳為以如後述的方式構成：在以第一區域5接觸的方式閉合兩顎部4的狀態，一顎部4的橫夾齒11的凸條111隔著均等的間隙進入另一顎部4的橫夾齒11的凹條112內。但是，於此，除了橫夾齒11的前端側部分（例如相連第一區域5的部分）以外的區域中，只要一顎部4的橫夾齒11的凸條111以隔著均等的間隙進入另一顎部4的橫夾齒11的凹條112內的方式構成，則兩顎部4的橫夾齒11可想成是：在以第一區域5接觸的方式閉合兩顎部4的狀態，一顎部4的橫夾齒11的凸條111，隔著均等的間隙進入的橫夾齒11會如上述，隔著均等的間隔進入另一顎部4的橫夾齒11的凹條112內。此間隙的長度例如較佳是0.1～0.4mm，更佳為0.25～0.35mm。再者，於此，均等的間隔可包含誤差程度的錯開等。Further, the lateral teeth 11 of the two jaw portions 4 are in a state in which the two jaw portions 4 are closed in such a manner that the first region 5 is in contact with each other, and the ridges 111 of the lateral teeth 11 of one jaw portion 4 do not contact the other jaw portion. 4 is formed in the manner of the inside of the concave strip 112 of the lateral teeth 11. Further, it is preferable that the lateral teeth 11 of the two jaw portions 4 are configured as follows, in a state in which the two jaw portions 4 are closed in such a manner that the first region 5 is in contact, and the convex teeth 11 of the one jaw portion 4 are convex. The strip 111 enters the recess 112 of the transverse nip 11 of the other shank 4 across the equal gap. However, here, in addition to the front end side portion of the lateral pinch 11 (for example, the portion connecting the first region 5), the ridges 111 of the lateral nip 11 of the shank portion 4 enter through the equal gap. The other portion 4 is formed in the concave strip 112 of the lateral teeth 11 so that the lateral teeth 11 of the two jaws 4 can be thought of as a state in which the two jaws 4 are closed in contact with the first region 5. The ribs 111 of the lateral nips 11 of the shank 4, the transverse nips 11 entering through the equal gaps, enter the concave strips 112 of the transverse nips 11 of the other shank 4 at equal intervals, as described above. Inside. The length of this gap is, for example, preferably from 0.1 to 0.4 mm, more preferably from 0.25 to 0.35 mm. Furthermore, here, the equal interval may include a shift in the degree of error or the like.

如圖3所示，在各顎部4的對向面14形成有凹部16；其中，凹部16從橫夾齒11夾住的區域延伸到抵達各顎部4的前端，橫夾齒11設在相對於第二區域6的前後方向而成為兩側的位置。相對於凹部16的前後方向垂直的剖面具有凹弧形狀。在各凹部16設有縱夾齒12。縱夾齒12具有從顎部4的前端朝向後方延伸的4個凸條121。但是，凹條121的數量只要為1以上即可，並不限制其數量。各凸條121例如可具有相同於上述橫夾齒11的凸條111的剖面形狀。於此，列舉各凸條121的突端呈尖銳的情況為例。As shown in FIG. 3, a concave portion 16 is formed in the opposing surface 14 of each of the jaw portions 4; wherein the concave portion 16 extends from a region sandwiched by the lateral teeth 11 to reach the front end of each of the jaw portions 4, and the lateral teeth 11 are provided at The positions on both sides are opposite to the front-rear direction of the second region 6. The cross section perpendicular to the front-rear direction of the recessed portion 16 has a concave arc shape. Longitudinal teeth 12 are provided in each of the recesses 16. The longitudinal pinch 12 has four ribs 121 extending rearward from the front end of the crotch portion 4. However, the number of the concave strips 121 may be one or more, and the number thereof is not limited. Each of the ridges 121 may have, for example, a cross-sectional shape of the ridges 111 which are the same as the lateral nips 11 described above. Here, a case where the protruding end of each of the ridges 121 is sharp is exemplified.

各顎部4的縱夾齒12具有的凸條121的至少前端側，在以第一區域5接觸的方式閉合兩顎部4的狀態中，以與對向的顎部4的縱夾齒12具有的凸條121的距離隨著從顎部4的前端遠離而遠離的方式傾斜。於此，如圖3所示，設在各凹部16的縱夾齒12具有的凸條121分別在對向位置具有凸條121，各凸條121從顎部4的前端至後方具有凹弧形狀，凹弧形狀與對向的凸條121在反對側呈凸狀。The longitudinal teeth 12 of each of the jaws 4 have at least the front end side of the ridges 121, and in a state in which the two jaws 4 are closed in contact with the first region 5, the longitudinal teeth 12 with the opposing jaws 4 The distance of the rib 121 having the inclination is inclined as it is away from the front end of the dam portion 4. Here, as shown in FIG. 3, the ribs 121 provided in the longitudinal nips 12 of the respective concave portions 16 have ridges 121 at the opposite positions, and each of the ribs 121 has a concave curved shape from the front end to the rear of the dam portion 4. The concave arc shape and the opposing rib 121 are convex on the opposite side.

像這樣，各凸條121的至少前端側，在以第一區域5接觸的方式閉合兩顎部4的狀態中，以與對向的顎部4的縱夾齒12具有的凸條121的距離隨著從顎部4的前端遠離而遠離的方式傾斜，藉此縮小顎部4的前端21與縱夾齒12的凸條121的前部夾住的角度θ（參照圖1），而能以縱夾齒12的凸條121的前部確實地夾持螺釘頭的圓弧周面。但是，各凸條121亦可不如上述而呈不傾斜。In this manner, at least the front end side of each of the ridges 121 is at a distance from the ridges 121 of the longitudinal nips 12 of the opposing dam portions 4 in a state where the dam portions 4 are closed in such a manner that the first regions 5 are in contact with each other. With the inclination away from the front end of the crotch portion 4 and away from each other, the angle θ (refer to FIG. 1) of the front end 21 of the crotch portion 4 and the front portion of the ridge 121 of the longitudinal pinch 12 is reduced, and The front portion of the rib 121 of the longitudinal pinch 12 surely grips the arcuate circumferential surface of the screw head. However, each of the ridges 121 may not be inclined as described above.

縱夾齒12具有的多個凸條121的前部，係面臨全部顎部4的前端21，在以第一區域5接觸的方式閉合兩顎部4的狀態中，縱夾齒12的凸條121的突端（即相當於尾根的部分）係夾住包含設在兩顎部4的第一區域5且彼此接觸的平面5a的平面，並透過間隙而對向。但是，亦可為不對向。各縱夾齒12的各凸條121自凹部16起的高度，在凸條121的前後方向的任意位置中令為恆常相同。但是，亦可令為恆常不相同。在顎部4的前端21的左右形成朝向顎部4的前端而前端狹窄狀地傾斜的傾斜側面22。再者，縱夾齒12的凸條121的突端是形成在比橫夾齒11的凹條112還低的位置。The longitudinal portion of the plurality of ribs 121 of the longitudinal pinch 12 faces the front end 21 of all the crotch portions 4, and in the state in which the crotch portions 4 are closed in such a manner that the first region 5 is in contact, the ridges of the longitudinal pinch teeth 12 The projecting end of 121 (i.e., the portion corresponding to the tail root) sandwiches the plane including the plane 5a provided in the first region 5 of the two jaw portions 4 and in contact with each other, and is opposed to each other through the gap. However, it can also be misaligned. The height of each of the ridges 121 of each of the longitudinal teeth 12 from the concave portion 16 is always the same at any position in the front-rear direction of the ridge 121. However, it can also be made to be different from one another. On the right and left sides of the front end 21 of the crotch portion 4, an inclined side surface 22 that is inclined toward the front end of the crotch portion 4 and whose front end is narrowly inclined is formed. Further, the projecting end of the rib 121 of the longitudinal pinch 12 is formed at a position lower than the groove 112 of the lateral pinch 11.

如上述，當在垂直於前後方向的剖面為凹弧形狀的凹部16設有延伸在前後方向的多個凸條121，使其前部面臨顎部4的前端21，則在張開顎部4並以一對縱夾齒12夾持螺釘頭時，能以縱夾齒12的凸條121確實地捕捉並夾持螺釘頭的圓弧周面。是以，在取下設在螺釘頭的十字狀的操作槽損壞的螺釘或螺紋生鏽的螺釘時，將縱夾齒12的凸條121壓接或咬入螺釘頭的圓弧周面，能將螺釘往鬆脫方向確實地轉動操作。尤其是，即使在除去從螺釘頭的圓弧周面的螺釘鎖緊面起的高度為小的扁圓頭螺絲或皿頭螺絲的情況，藉由將兩顎部4的前端21的凹部16附近密接於螺釘鎖緊面，使凸條121的前部咬入螺釘頭的圓弧周面，而能確實地除去小的扁圓頭螺絲或皿頭螺絲。As described above, when the concave portion 16 having a concave arc shape in a cross section perpendicular to the front-rear direction is provided with a plurality of ribs 121 extending in the front-rear direction so that the front portion faces the front end 21 of the crotch portion 4, the open portion is opened. 4 When the screw head is held by the pair of longitudinal teeth 12, the arcuate surface of the screw head can be surely caught and held by the ridges 121 of the longitudinal teeth 12. Therefore, when the screw or the threaded rusted screw provided in the cross-shaped operation groove of the screw head is removed, the ridge 121 of the longitudinal pinch 12 is crimped or bitten into the arcuate surface of the screw head, and Rotate the screw in the loose direction. In particular, even in the case where the height of the flat head screw or the head screw which is small from the screw locking surface of the circular arc circumferential surface of the screw head is removed, by the concave portion 16 of the front end 21 of the two jaw portions 4 It is in close contact with the screw locking surface, so that the front portion of the rib 121 bites into the circular arc surface of the screw head, and the small oblate screw or the head screw can be reliably removed.

接著，針對由鉗子100的兩顎部4夾持夾持對象的功能，參照圖6等說明。Next, the function of clamping the object to be clamped by the two jaw portions 4 of the forceps 100 will be described with reference to FIG. 6 and the like.

當握住鉗子100的兩臂部1的手柄2，則兩顎部4的張開間隔會漸變窄。在兩顎部4之間沒有夾持對象的情況，兩顎部4的第一區域5彼此接觸而前端碰觸的時間點下，會成為兩顎部4閉合的狀態。此狀態為手柄2到達握入限度的狀態。在此閉合狀態中，兩顎部4的一者的橫夾齒11的凸條111進入另一者的橫夾齒11的凹條112，且橫夾齒11彼此呈不接觸的狀態。藉此，能防止橫夾齒11的劣化等。When the handle 2 of the arms 1 of the forceps 100 is grasped, the opening interval of the two jaws 4 is gradually narrowed. When there is no object to be sandwiched between the two jaws 4, the first region 5 of the two jaws 4 is in contact with each other and the front end is in contact with each other, and the two jaws 4 are closed. This state is a state in which the handle 2 reaches the grip limit. In this closed state, the ridges 111 of the lateral nips 11 of one of the two jaws 4 enter the concave strips 112 of the other lateral nipples 11, and the lateral nips 11 are in a state of no contact with each other. Thereby, deterioration of the lateral teeth 11 and the like can be prevented.

設在鉗子100的兩顎部4的前端側的第一區域5，因為具有在將手柄2握住到握入限度為止而閉合兩顎部4的狀態會相互接觸的部分（例如接觸的平面5a），即使是片材體等厚度為薄的夾持對象，藉由閉合兩顎部4，使第一區域5的接觸部分能夾持，而能只用兩顎部4的前端側夾持厚度為薄的夾持對象。舉例而言，如圖6（a）所示，能藉由第一區域5夾持厚度為薄的片材體50。再者，作為夾持對象，例如能列舉：金屬製片材體、塑膠片材、金屬線材、電線、皮革片材、橡膠片材、塑膠片、布帛等。片材體50例如是金屬製片材體、塑膠片材、皮革片材、橡膠片材等。The first region 5 provided on the front end side of the crotch portion 4 of the forceps 100 has a portion in which the state in which the two crotch portions 4 are closed while holding the handle 2 to the gripping limit (for example, the contact plane 5a) The contact portion of the first region 5 can be clamped by closing the two jaw portions 4 even if the thickness is such that the sheet body is thin, and the thickness can be sandwiched only by the front end sides of the two jaw portions 4. For thin gripping objects. For example, as shown in FIG. 6(a), the sheet body 50 having a small thickness can be sandwiched by the first region 5. In addition, examples of the object to be clamped include a metal sheet body, a plastic sheet, a metal wire, an electric wire, a leather sheet, a rubber sheet, a plastic sheet, a fabric, and the like. The sheet body 50 is, for example, a metal sheet body, a plastic sheet, a leather sheet, a rubber sheet, or the like.

又，在以兩顎部4的對向的一對橫夾齒11夾持片材體50的情況中，如圖6（b）所示，當握住手柄2並以一對橫夾齒11夾持片材體50的端部的上下面，則橫夾齒11接觸片材體50且以上下的凸條111的突端111a承受片材體50；其中，片材體係厚度為薄的夾持對象一例子，上下的凸條位在錯開一半間距的位置。當從此狀態更握入手柄2，則片材體50被第一區域5夾住，且如圖6（c）所示，一顎部4的橫夾齒11的多個凸條111的突端111a側，分別進入設在對向位置的另一顎部4的橫夾齒11的凹條112內，而能使片材體50塑性變形為連續的山谷狀。藉此，能以對向的橫夾齒11穩固地夾持片材體50，故相較於只用第一區域5之間夾住片材體50的情況，能更加確實地夾持片材體50。又，藉由以第一區域5與多個凸條111的突端111a附近夾持夾持對象，而能在多個位置將夾持對象夾持，進而能穩定地夾持。又，在維持穩固地夾持片材體50的狀態，將片材體50拉伸操作後，能準確地進行將片材體50的整體從裝設部分拉出的作業或折曲夾持部分的作業等的二次作業。Further, in the case where the sheet body 50 is sandwiched by the pair of lateral teeth 11 opposed to the two jaw portions 4, as shown in Fig. 6(b), when the handle 2 is held and a pair of lateral teeth 11 are used When the upper and lower sides of the end portion of the sheet body 50 are sandwiched, the lateral pin 11 contacts the sheet body 50 and the protruding end 111a of the upper and lower ribs 111 receives the sheet body 50; wherein the thickness of the sheet system is thin. In the case of the object, the upper and lower ribs are located at a position offset by half. When the handle 2 is further gripped from this state, the sheet body 50 is sandwiched by the first region 5, and as shown in Fig. 6(c), the projecting end 111a of the plurality of ribs 111 of the lateral nip 11 of the shank portion 4 is shown. The side enters the concave strip 112 of the lateral pin 11 of the other crotch portion 4 provided at the opposite position, respectively, so that the sheet body 50 can be plastically deformed into a continuous valley shape. Thereby, the sheet body 50 can be firmly held by the opposing lateral teeth 11 so that the sheet can be more reliably held than when the sheet body 50 is sandwiched between the first regions 5 only. Body 50. Further, by sandwiching the nip object in the vicinity of the projecting end 111a of the plurality of ribs 111 in the first region 5, the nip object can be held at a plurality of positions, and the nip can be stably held. Moreover, after the sheet body 50 is stretched in a state where the sheet body 50 is firmly held, the operation of pulling the entire sheet body 50 from the mounting portion or the bending holding portion can be accurately performed. Secondary work such as work.

又，使橫夾齒11後方的凸條111配置的間距比前方的凸條111配置的間距P1還寬，且令後方的凸條111的高度比前方的凸條的高度高，藉此如圖6（b）與圖6（c）所示，只藉由橫夾齒11前方中間距P1變小且高度為低的凸條111，能區分為夾持片材體50的使用形態與以橫夾齒11的整體夾持片材體50的使用形態。舉例而言，在以橫夾齒11整體夾持片材的情況，藉由間距為大且高度為高的凸條111夾持片材體50，使凸條111與片材體50的接觸面積變大，能確實地防止凸條111與片材體50相對地滑動。Further, the pitch at which the ridges 111 on the rear side of the lateral nip 11 are disposed is wider than the pitch P1 at which the front ribs 111 are disposed, and the height of the rear ribs 111 is higher than the height of the ridges on the front side. 6(b) and FIG. 6(c), it is possible to distinguish between the use form of the holding sheet body 50 and the horizontal direction by the ridges 111 which are smaller by the pitch P1 in the front direction of the lateral nip 11 and have a lower height. The entire shape of the teeth 11 holds the form of use of the sheet body 50. For example, in the case where the sheet is sandwiched by the lateral teeth 11 as a whole, the sheet body 50 is sandwiched by the ridges 111 having a large pitch and a high height, so that the contact area between the ridges 111 and the sheet body 50 is made. When it is enlarged, it is possible to surely prevent the ridge 111 from sliding relative to the sheet body 50.

以上，若根據本實施形態，藉由如後述的構成方式，在閉合兩顎部4的狀態，能使橫夾齒11不接觸而防止橫夾齒11的劣化等，進而能防止工具的劣化：在以第一區域5接觸的方式閉合兩顎部4的狀態，一顎部4的橫夾齒11的凸條111進入另一顎部4的橫夾齒11的凹條112內，且一顎部4的橫夾齒11的凸條111不接觸另一顎部4的橫夾齒11的凹條112。As described above, according to the configuration of the present embodiment, the state in which the two jaw portions 4 are closed can prevent the lateral teeth 11 from coming into contact with each other, thereby preventing deterioration of the lateral teeth 11 and the like, and further preventing deterioration of the tool: In a state in which the two crotch portions 4 are closed in such a manner that the first region 5 is in contact, the ribs 111 of the lateral nip 11 of one shank portion 4 enter the concave strip 112 of the lateral nip 11 of the other crotch portion 4, and one 颚The rib 111 of the lateral pin 11 of the portion 4 does not contact the recess 112 of the lateral nip 11 of the other crotch portion 4.

又，若根據本實施形態，即使是片材狀的構件等厚度為薄的夾持對象，藉由設在兩顎部4的前端側的第一區域5中，在閉合兩顎部4的情況會接觸的部分（例如平面5a等）作夾持，而能只用兩顎部4的前端側夾持厚度為薄的夾持對象，可適宜地夾持厚度為薄的夾持對象。Further, according to the present embodiment, even in the case where the thickness of the member such as a sheet-like member is thin, the two dam portions 4 are closed by the first region 5 provided on the distal end side of the crotch portion 4 The portion to be contacted (for example, the flat surface 5a or the like) is sandwiched, and the holding target having a small thickness can be sandwiched only by the front end side of the two jaw portions 4, and the holding object having a small thickness can be appropriately sandwiched.

又，藉由將夾持對象以兩顎部4的對向的橫夾齒11夾入，而非以第一區域5夾住夾持對象，則一顎部4的橫夾齒11的凸條111進入對向的另一顎部4的橫夾齒11的凹條112，藉此使夾持對象塑性變形為山谷狀，即使是厚度為薄的夾持對象亦能確實地夾持。Further, by sandwiching the clamping object 11 with the opposing lateral teeth 11 of the two jaws 4 instead of sandwiching the clamping object with the first region 5, the ridges of the lateral teeth 11 of the one portion 4 111 enters the concave strip 112 of the transverse pin 11 of the other crotch portion 4, whereby the object to be clamped is plastically deformed into a valley shape, and the object to be clamped can be surely held even if the thickness is small.

再者，雖在上述實施形態中，針對如後述的橫夾齒11設在兩顎部4的對向面14的情況進行說明：在前方具有以間距P1配置的多個凸條111，在後方具有以比間距P1還寬的間距配置的較前方的凸條111的高度還高的多個凸條111。惟在本發明中，具有隨著配置的位置往後方階段性地間距變寬且高度變高的多個凸條111的橫夾齒11只要設在兩顎部4的對向面14即可，即使在這樣的情況，亦能產生相同於上述實施形態的功效。於此，階段性地是指兩階段以上的階段，亦即在橫夾齒11具有的凸條111整體中，間距與高度為兩階段以上的變化即可，舉例而言，可為具有間距與高度不變化的鄰接的2個以上凸條111。舉例而言，在一個橫夾齒11中，若間距與高度在整體為兩階段以上地變大，則可想成是意指：間距與高度至少一方為相同的凸條111連續且部分地配置。在此，間距與高度一方為階段性地變化的情況亦相同。In the above-described embodiment, the case where the lateral teeth 11 to be described later are provided on the opposing faces 14 of the two jaw portions 4 will be described. The front side has a plurality of ribs 111 arranged at the pitch P1, and is rearward. There are a plurality of ribs 111 having a height higher than that of the front ribs 111 arranged at a wider pitch than the pitch P1. However, in the present invention, the lateral teeth 11 having the plurality of ridges 111 which are gradually widened in the stepwise direction and height-increasing with the position of the arrangement are provided on the opposing faces 14 of the two jaw portions 4, Even in such a case, the same effect as the above embodiment can be produced. Here, the stage refers to a stage of two or more stages, that is, in the whole of the ridges 111 of the lateral teeth 11 , the pitch and the height may be two or more stages, for example, it may have a pitch and Two or more ribs 111 adjacent to each other whose height does not change. For example, in one of the lateral teeth 11, if the pitch and the height become larger than two stages as a whole, it is conceivable that the ridges 111 having at least one of the same pitch and height are continuously and partially arranged. . Here, the case where the pitch and the height are changed stepwise is also the same.

再者，在本發明中，橫夾齒11中間距與高度相同的多個凸條111，或間距與高度至少一方不同的多個凸條111的配置形態或其組合等，可無須為上述實施形態1所示的形態，能對應所需自由地變更。Further, in the present invention, the arrangement of the plurality of ridges 111 having the same pitch and height in the lateral nip 11 or the arrangement of the plurality of ridges 111 having different pitches and heights, or the like, need not be performed as described above. The form shown in the form 1 can be freely changed in accordance with the necessity.

以下，針對橫夾齒11的變形例使用圖8與圖9說明。再者，在以下的說明中，相同於實施形態1的構件，賦予相同的符號並省略其說明。Hereinafter, a modification of the lateral pin 11 will be described with reference to FIGS. 8 and 9. In the following description, members that are the same as those in the first embodiment are denoted by the same reference numerals, and their description is omitted.

（變形例1） 圖8（a）為用以說明橫夾齒11的變形例1，從連結軸方向觀看橫夾齒11的附近的圖。在此變形例1中，橫夾齒11，由形狀與大小相同且以相同間距在前後方向排列的多個凸條111構成；一顎部4的橫夾齒11相對於另一顎部4的橫夾齒，在前後方向只錯開橫夾齒的凸條的排列間距的一半間距量而設置，且在以第一區域接觸的方式閉合兩顎部的狀態，一顎部的橫夾齒的凸條的突端與另一顎部的橫夾齒的凹條的底端，在凸條的高度方向，以不接觸狀態正對。(Variation 1) FIG. 8(a) is a view for explaining a modification 1 of the lateral pin 11 and the vicinity of the lateral pin 11 as seen from the direction of the connecting axis. In the first modification, the lateral teeth 11 are composed of a plurality of ribs 111 having the same shape and size and arranged in the front-rear direction at the same pitch; the lateral teeth 11 of one shank 4 are opposed to the other shank 4 The transverse teeth are disposed in the front-rear direction by shifting only half the pitch of the arrangement pitch of the ridges of the lateral teeth, and in the state in which the two sides are closed in contact with the first region, the convexity of the transverse teeth of one turn The bottom end of the strip of the strip and the bottom of the strip of the other jaw are in the non-contact state in the height direction of the strip.

舉例而言，在圖8（a）係表示如後述的例子：各橫夾齒11的凸條111分別形成為相同大小的三角形狀，且排列間距P設定為相同。在此例子中，凸條111的突端111a與鄰接凸條111的凹條112的底端112a皆被修圓。舉例而言，從凹條112的底端112a到凸條111的突端111a的高度為0.6mm時，令凸條111的突端111a的半徑值為0.2mm，令凹條112的底端112a的半徑值為0.3mm。For example, FIG. 8( a ) shows an example in which the ridges 111 of the respective lateral ribs 11 are each formed in a triangular shape having the same size, and the arrangement pitch P is set to be the same. In this example, the projecting end 111a of the rib 111 and the bottom end 112a of the recess 112 of the abutting rib 111 are rounded. For example, when the height from the bottom end 112a of the concave strip 112 to the protruding end 111a of the ridge 111 is 0.6 mm, the radius of the protruding end 111a of the ridge 111 is 0.2 mm, and the radius of the bottom end 112a of the concave strip 112 is made. The value is 0.3 mm.

（變形例2） 圖8（b）為用以說明橫夾齒11的變形例2，從連結軸方向觀看橫夾齒11的附近的圖。此變形例2係不將變形例1的凸條111的突端111a修圓的外隅角，不將凹條112的底端112a修圓的內隅角者，藉此能使夾持物不易錯開。(Variation 2) FIG. 8(b) is a view for explaining a modification 2 of the lateral pin 11 and the vicinity of the lateral pin 11 as seen from the direction of the connecting axis. This modification 2 is an outer corner which does not round the protruding end 111a of the ridge 111 of the first modification, and does not round the inner end 112a of the concave strip 112, whereby the holder can be easily staggered.

（變形例3） 圖8（c）為用以說明橫夾齒11的變形例3，從連結軸方向觀看橫夾齒11的附近的圖。此變形例3，為加大變形例1中凸條111的突端111a附近與凹條112的底端附近的圓角半徑，並令剖面形狀為連續的波形形狀；其中，剖面形狀沿著橫夾齒11的表面的前後方向。如此，當令橫夾齒11形成為連續波形，則在以橫夾齒11夾持片材體50等的夾持對象的狀態中，能一邊確實地夾持夾持對象，一邊緩慢地使其變形，故適合不想損傷夾持對象的表面的情況。(Modification 3) FIG. 8(c) is a view for explaining a modification 3 of the lateral teeth 11, and the vicinity of the lateral teeth 11 is viewed from the direction of the connection axis. In the third modification, the radius of the corner of the vicinity of the protruding end 111a of the ridge 111 in the vicinity of the bottom end of the concave strip 112 in the modification 1 is increased, and the cross-sectional shape is a continuous waveform shape; wherein the sectional shape is along the horizontal clip The front-rear direction of the surface of the tooth 11. In the state in which the horizontal nip 11 is formed in a continuous shape, the nip object can be reliably deformed while holding the nip object in a state in which the nip object such as the sheet body 50 is held by the lateral nip 11 Therefore, it is suitable for the case where the surface of the object to be clamped is not damaged.

（變形例4） 圖9（a）為用以說明橫夾齒11的變形例4，從連結軸方向觀看橫夾齒11的附近的圖。此變形例為上述實施形態1的橫夾齒11中，凸條111的間距皆為相同，惟其高度H係隨著從橫夾齒11的前方朝向後方階段性地變小之物。如此，當以高度H不同的多個凸條111構成橫夾齒11，則相同於本實施形態，可區分使用形態為：以具有高度H為大的凸條111之橫夾齒11的前半部分夾持片材體50等的夾持對象、及以橫夾齒11的整體夾持片材體50等的夾持對象。又，藉由以高度H為大的凸條111夾持片材體50等的夾持對象，使凸條111與片材體50等的接觸對象的接觸面積變大，能確實地防止橫夾齒11與片材體50等的夾持對象相對地滑動。(Variation 4) FIG. 9(a) is a view for explaining a modification 4 of the lateral pin 11 and the vicinity of the lateral pin 11 as seen from the direction of the connecting axis. In this modification, in the lateral nip 11 of the first embodiment, the pitch of the ridges 111 is the same, but the height H is gradually reduced from the front side of the lateral nip 11 toward the rear. As described above, when the lateral ribs 11 are formed by the plurality of ridges 111 having different heights H, the same manner as in the present embodiment can be used to distinguish the first half of the lateral spurs 11 of the ridges 111 having the height H as large. The object to be gripped by the sheet body 50 and the like, and the object to be sandwiched by the sheet body 50 and the like are sandwiched by the entire of the lateral teeth 11 . In addition, by sandwiching the object to be sandwiched by the sheet body 50 or the like with the ridges 111 having a large height H, the contact area between the ridges 111 and the sheet member 50 and the like is increased, and the cross clamp can be reliably prevented. The teeth 11 slide relative to the object to be clamped by the sheet body 50 or the like.

In this modification, in the first modification, the ridges 111 and the concave strips 112 having a quadrangular shape as viewed from the axial direction of the connecting shaft 3b constitute the lateral teeth 11 .

（變形例7） 圖14為用以說明橫夾齒11的變形例7，表示閉合兩顎部4的狀態中兩顎部的前端附近的圖（圖14（a））、以圖14（a）的區域D表示的部分的放大圖（圖14（b））、表示兩顎部4在前後方向錯開的情況中兩顎部4的前端附近的圖（圖14（c））以及以圖14（a）的區域E表示的部分的放大圖（圖14（d））。(Variation 7) FIG. 14 is a view showing a modification 7 of the lateral pin 11 and showing a vicinity of the front end of the two crotch portions in a state in which the crotch portions 4 are closed (FIG. 14(a)), and FIG. 14(a) An enlarged view of a portion indicated by a region D (Fig. 14 (b)), a view showing the vicinity of the front end of the two jaw portions 4 in the case where the two jaw portions 4 are shifted in the front-rear direction (Fig. 14 (c)), and Fig. 14 An enlarged view of a portion indicated by a region E of (a) (Fig. 14 (d)).

此變形例為在上述實施形態中，如圖14（a）與圖14（b）所示，在以第一區域5接觸的方式閉合兩顎部4的狀態，即以一顎部4的橫夾齒11的凸條111的突端111a與該凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a在凸條111的高度方向正對的方式將兩顎部4組合的狀態下，橫夾齒11具有，一顎部4的橫夾齒111的凸條111與該凸條111進入的另一顎部4的橫夾齒11的凹條112的對向的側面間的間隔130，比該凸條111的突端111a與該凹條112的底端112a的間隔131大的形狀之物。一顎部4的橫夾齒11的凸條111，與該凸條111進入的另一顎部4的橫夾齒11的凹條112的對向的側面間的間隔130，例如，為一顎部4的橫夾齒11的凸條111的兩個側面111b，與該凸條111進入的另一顎部4的橫夾齒11的凹條112的兩個側面112b之中，隔著間隙相互地對向的側面111b與112b間的間隔130。於此的側面111b與側面112b的間隔130例如可想成是側面111b與側面112b中間隔最寬的部分的間隔。In the above-described embodiment, as shown in FIGS. 14(a) and 14(b), the two crotch portions 4 are closed so as to be in contact with the first region 5, that is, the cross-section of the crotch portion 4 The protruding end 111a of the rib 111 of the dent 11 and the bottom end 112a of the concave strip 112 of the lateral nip 11 of the other rim 4 of the dent 11 enter the two slant portions in the height direction of the ridge 111 In the combined state, the lateral teeth 11 have the ribs 111 of the lateral nips 111 of one shank 4 and the concave strips 112 of the transverse nips 11 of the other shank 4 into which the ribs 111 enter. The space 130 between the side faces is larger than the space 131 between the projecting end 111a of the ridge 111 and the bottom end 112a of the recess 112. For example, the space 130 between the ribs 111 of the lateral nip 11 of one shank 4 and the opposite side of the concave strip 112 of the lateral nip 11 of the other shank 4 into which the ridge 111 enters is, for example, a ridge The two side faces 111b of the ridges 111 of the lateral nip 11 of the portion 4 and the two side faces 112b of the concave strip 112 of the lateral nip 11 of the other shank portion 4 into which the ribs 111 enter are separated from each other by a gap The spacing 130 between the opposite sides 111b and 112b. The interval 130 between the side surface 111b and the side surface 112b is considered to be, for example, the interval between the side surface 111b and the side surface 112b which are the widest interval.

組合兩顎部4的狀態，例如可想成是將第一臂部1a與第二臂部1b以連結部3連結的狀態。於此，以一顎部4的橫夾齒11的凸條111的突端111a與該凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a在凸條111的高度方向正對的方式將兩顎部4組合的狀態，可想成是假設成此狀態的情況，兩顎部4亦可因製造時的誤差等，而未必以成為如上述狀態的方式組合。以第一區域5接觸的方式閉合兩顎部4的狀態為如後述的狀態：以一顎部4的橫夾齒11的凸條111的突端111a與該凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a，在凸條111的高度方向正對的方式組合兩顎部4，上述狀態例如可認為是，以第一區域5接觸的方式閉合兩顎部4，亦即以一顎部4的橫夾齒11的凸條111的突端111a與該凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a的距離為最短的方式組合兩顎部4的狀態。The state in which the two arm portions 4 are combined is, for example, a state in which the first arm portion 1a and the second arm portion 1b are coupled to each other by the connecting portion 3. Here, the protruding end 111a of the ridge 111 of the lateral nip 11 of one shank 4 and the bottom end 112a of the concave strip 112 of the lateral nip 11 of the other shank 4 of the ridge 4 are in the rib 111. The state in which the heights are facing each other in a state in which the two jaws 4 are combined is considered to be a state assumed to be in this state, and the two jaws 4 may be combined in such a manner as to be in the above state due to an error in manufacturing or the like. The state in which the two crotch portions 4 are closed in such a manner that the first region 5 is in contact is a state as will be described later: the projecting end 111a of the ridge 111 of the lateral nip 11 of the shank portion 4 and the other crotch portion 4 into which the rib 111 enters The bottom end 112a of the concave strip 112 of the lateral pin 11 is combined with the two crotch portions 4 in such a manner that the height direction of the rib 111 is opposite. The above state can be considered as, for example, closing the two crotch portions in such a manner that the first region 5 is in contact with each other. 4, that is, the distance between the protruding end 111a of the ridge 111 of the lateral nip 11 of the shank 4 and the bottom end 112a of the concave strip 112 of the lateral nip 11 of the other shank 4 into which the rib 111 enters is the shortest. The way to combine the state of the two jaws 4.

在上述實施形態的鉗子中，例如因加工誤差或組合誤差等，使第一臂部1a與第二臂部1b的連結位置等錯開，且兩顎部4的橫夾齒11的位置關係等在凸條111的高度方向錯開，導致兩顎部4彼此以比原設計還接近的方式配置，即使如此，在閉合兩顎部4時，一顎部4的橫夾齒11的凸條111的突端111a，與該凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a亦不易引起相互接觸。在此情況，因為兩顎部4以連結部3為中心轉動，所以凸條111的突端111a即使接觸，仍可想成是接觸該凸條111進入的凹條112的側面112b。因此，舉例而言，閉合兩顎部4的狀態中，一顎部4的橫夾齒11的凸條111的突端111a與此凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a在凸條111的高度方向的間隔131，可為了容易夾住薄的夾持對象等而預先設定為狹窄。In the forceps of the above-described embodiment, the connection position of the first arm portion 1a and the second arm portion 1b is shifted, for example, due to a machining error, a combination error, or the like, and the positional relationship between the lateral teeth 11 of the two jaw portions 4 is The height direction of the ribs 111 is staggered, so that the two jaws 4 are disposed in a manner closer to each other than the original design. Even so, when the two jaws 4 are closed, the protruding ends of the ribs 111 of the lateral teeth 11 of one of the jaws 4 are closed. 111a, the bottom end 112a of the concave strip 112 of the lateral pin 11 of the other crotch portion 4 into which the ridge 111 enters is also less likely to cause mutual contact. In this case, since the two jaw portions 4 are rotated about the joint portion 3, even if the projecting end 111a of the ridge 111 is in contact, it can be thought of as the side surface 112b of the recessed strip 112 that contacts the rib 111. Thus, for example, in the state in which the two jaw portions 4 are closed, the projecting end 111a of the ridge 111 of the lateral nip 11 of one shank 4 and the tang of the traverse pin 11 of the other shin portion 4 into which the rib 111 enters The gap 131 between the bottom end 112a of the strip 112 in the height direction of the ridge 111 can be set to be narrow in advance in order to easily sandwich a thin gripping object or the like.

然而，在一顎部4的橫夾齒11的凸條111與該凸條111進入的另一顎部4的橫夾齒11的凹條112對向的側面間的間隔130，令其為該凸條111的突端111a與凹條112的底端112a在凸條111的高度方向中的間隔131以下的情況，因加工誤差或組合誤差等，第一臂部1a與第二臂部1b的連結位置等錯開，兩顎部4的相對位置關係在前後方向錯開，如此，在閉合兩顎部4的狀態，一顎部4的凸條111的突端111a會碰觸該凸條111進入的另一顎部4的橫夾齒11的凹條112的側面112b，可推知會導致突端111a的劣化。兩顎部4的前後方向中相對位置關係錯開，例如可想成是：將一顎部4的凸條111的突端111a對於該凸條111進入的另一顎部4的凹條112的底端112a在凸條111的高度方向正對的狀態，設為沒有錯開的狀態的情況。兩顎部4在前後方向錯開，例如是在以第一區域5接觸的方式閉合兩顎部4的狀態中，一顎部4的凸條111的突端111a對於該凸條111進入的另一顎部4的凹條112的底端112a，在凸條111的高度方向呈非正對的狀態。However, the space 130 between the ribs 111 of the lateral nip 11 of one of the ridges 4 and the side of the traverse 112 of the traverse 11 of the other shank 4 of the shank 111 is such that When the protruding end 111a of the ridge 111 and the bottom end 112a of the concave strip 112 are equal to or smaller than the interval 131 in the height direction of the ridge 111, the first arm portion 1a and the second arm portion 1b are connected due to a machining error, a combination error, or the like. When the position is staggered, the relative positional relationship between the two jaws 4 is shifted in the front-rear direction, so that in the state in which the two jaws 4 are closed, the protruding end 111a of the ridges 111 of one of the jaws 4 touches the other of the ribs 111. The side surface 112b of the concave strip 112 of the lateral pin 11 of the crotch portion 4 can be inferred to cause deterioration of the protruding end 111a. The relative positional relationship in the front-rear direction of the two jaw portions 4 is staggered, for example, as follows: the bottom end of the concave strip 112 of the other crotch portion 4 into which the projecting end 111a of the ridge portion 111 of one shank portion 4 enters the rib portion 111 The state in which 112a is facing in the height direction of the ridge 111 is a state in which it is not shifted. The two jaws 4 are staggered in the front-rear direction, for example, in a state in which the two jaws 4 are closed in such a manner that the first region 5 is in contact with each other, the protruding end 111a of the protruding strip 111 of one of the jaws 4 enters the other side of the protruding strip 111 The bottom end 112a of the concave strip 112 of the portion 4 is in a non-positive state in the height direction of the ridge 111.

因此，如本變形例所述，閉合兩顎部4的狀態，為以一顎部4的橫夾齒11的凸條111的突端111a，與該凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a，在凸條111的高度方向正對的方式組合兩顎部4的狀態下，橫夾齒11，具有一顎部4的橫夾齒111的凸條111與該凸條111進入的另一顎部4的橫夾齒11的凹條112的對向的側面間的間隔130，比該凸條111的突端111a與該凹條112的底端112a的間隔131大的形狀，藉此，使一顎部4的橫夾齒11的凸條111的突端111a，與該凸條111進入的另一顎部4的橫夾齒11的凹條112的底端112a的凸條111的高度方向的間隔131變窄，能以橫夾齒容易地夾住薄的夾持對象等，且即使在因第一臂部1a與第二臂部1b產生的加工誤差或組合誤差等所導致兩顎部4的相對位置關係在前後方向錯開的情況（例如圖14（c）與圖14（d）所示的情況）等，使一顎部4的凸條111的突端111a不易碰觸該凸條111進入的另一顎部4的橫夾齒11的凹條112的側面112b，能防止突端111a的劣化。同樣地，即使在因第一臂部1a與第二臂部1b產生的加工誤差或組合誤差等，所導致兩顎部4的相對位置關係在凸條的高度方向錯開的情況，使一顎部4的凸條111的突端111a不易碰觸該凸條111進入的另一顎部4的橫夾齒11的凹條112的側面112b，而能防止突端111a的劣化。Therefore, as described in the present modification, the state in which the two jaw portions 4 are closed is the projection end 111a of the ridge 111 of the lateral nip 11 of the shank portion 4, and the traverse of the other shin portion 4 into which the ridge 111 enters. The bottom end 112a of the concave strip 112 of the pinion 11 is in the state in which the two jaws 4 are combined in the height direction of the ridge 111, and the lateral nip 11 has a ridge of the lateral nip 111 of the dam portion 4. The space 130 between the opposite side faces of the concave strip 112 of the lateral pin 11 of the other crotch portion 4 into which the ridge 111 enters is larger than the protruding end 111a of the rib 111 and the bottom end 112a of the concave strip 112. The shape of the space 131 is large, whereby the protruding end 111a of the rib 111 of the lateral pin 11 of one shank 4 and the bottom of the concave strip 112 of the lateral nip 11 of the other crotch portion 4 into which the rib 111 enters The interval 131 in the height direction of the ridges 111 of the end 112a is narrowed, and it is possible to easily sandwich a thin nip object or the like with the lateral nip, and even in the machining error caused by the first arm portion 1a and the second arm portion 1b. Or a combination of errors or the like causes the relative positional relationship between the two jaws 4 to be shifted in the front-rear direction (for example, as shown in FIGS. 14(c) and 14(d)), etc., so that the ridges 111 of one of the jaws 4 are Burst Another jaw portion 111a of the ridge 111 touches easily cross into the clamp 4 of the concave side surface 11 of the tooth 112 112b, possible to prevent deterioration of the protruding end 111a. Similarly, even in the case of a machining error or a combination error or the like caused by the first arm portion 1a and the second arm portion 1b, the relative positional relationship between the two jaw portions 4 is shifted in the height direction of the ridges, so that one portion is made The protruding end 111a of the ridge 111 of the 4 does not easily touch the side surface 112b of the concave strip 112 of the lateral nip 11 of the other dam portion 4 into which the ridge 111 enters, and the deterioration of the protruding end 111a can be prevented.

再者，在此變形例中，舉例而言，對向的側面111b與側面112b間的間隔130，在閉合兩顎部4的狀態，相對於凸條111的突端111a與該凸條111進入的凹條112的底端112a在凸條111的高度方向中的間隔131，較佳為寬0.02mm以上，或較佳為寬0.04mm以上。舉例而言，間隔131為0.1mm的情況，可令間隔130為0.148mm。又，在此情況中，對向的側面111b與側面112b間的前後方向的距離132，例如可為0.202mm。但是，上述的數值僅為一例，當然亦可為此以外的數值。舉例而言，上述的間隔130、131及距離132可根據鉗子的大小或形狀等適當設定。Further, in this modification, for example, the interval 130 between the opposite side surface 111b and the side surface 112b enters the protruding end 111a of the rib 111 and the ridge 111 in a state in which the two dam portions 4 are closed. The interval 131 of the bottom end 112a of the concave strip 112 in the height direction of the ridge 111 is preferably 0.02 mm or more in width, or preferably 0.04 mm or more in width. For example, in the case where the interval 131 is 0.1 mm, the interval 130 can be made 0.140 mm. Moreover, in this case, the distance 132 of the front-back direction between the opposing side surface 111b and the side surface 112b can be 0.202 mm, for example. However, the above numerical values are merely examples, and of course, values other than this may be used. For example, the above-described intervals 130, 131 and the distance 132 may be appropriately set according to the size or shape of the forceps.

再者，在此變形例中說明的構成，例如只要為以如後述的方式構成的夾持工具，則亦能適用在上述實施形態的鉗子以外的夾持工具：在閉合兩顎部的狀態，一顎部的橫夾齒的凸條進入凹條內，凹條鄰接另一顎部的橫夾齒的凸條，且一顎部的橫夾齒的凸條不接觸另一顎部的橫夾齒的凹條。舉例而言，只要為以如後述的方式構成的夾持工具，則亦能適用在上述實施形態的鉗子以外的夾持工具：在以閉合兩顎部的狀態接觸的接觸部與接觸部接觸的方式閉合兩顎部的狀態下，一顎部的橫夾齒的凸條，進入鄰接另一顎部的橫夾齒的凸條的凹條內，且另一顎部的橫夾齒的凸條，不接觸另一顎部的橫夾齒的凹條。於此，閉合兩顎部的狀態，例如可想成是將臂部的手柄握住到握入限度為止的狀態。In addition, the configuration described in the above-described modification can be applied to a holding tool other than the forceps of the above-described embodiment, for example, in a state in which the two jaws are closed, as long as it is a holding tool configured as described later. The ridges of the transverse teeth of one jaw enter the concave strip, the concave strips abut the ridges of the transverse teeth of the other jaw, and the ridges of the transverse teeth of one jaw do not contact the transverse clip of the other jaw The concave groove of the tooth. For example, as long as it is a holding tool which is configured as described later, the holding tool other than the forceps of the above-described embodiment can be applied to the contact portion which is in contact with the contact portion in a state in which the two crotch portions are closed. In the state in which the two jaws are closed, the ridges of the transverse teeth of one jaw enter the concave strip of the ridge of the transverse nip adjacent to the other ridge, and the ridge of the transverse ridge of the other ridge , does not touch the concave strip of the transverse jaw of the other crotch. Here, the state in which the two crotch portions are closed, for example, is considered to be a state in which the handle of the arm portion is held to the gripping limit.

The ridges provided at the two ridges are arranged in a state in which the ridges are displaced in the front-rear direction, and it is conceivable that the ridges provided adjacent to the ridges are also displaced in the front-rear direction.

再者，於此的接觸部可想成是在閉合兩顎部的狀態會接觸，且限制在閉合兩顎部的狀態中於凸條的高度方向中的兩顎部的相對位置關係的接觸部，亦可想成是在閉合兩顎部的狀態會接觸，且在閉合兩顎部的狀態中阻礙一顎部往另一顎部方向移動的接觸部。又，於此的接觸部，例如是藉由接觸而限制臂部1的握入限度者，例如可想成是限制握入限度的止動件。舉例而言，於此，接觸部可為相當於本實施形態中，在閉合兩顎部4的情況接觸的第一區域5者。又，此接觸部，例如可為設在夾持工具的兩顎部的橫夾齒與連結部之間的對向面，且在閉合兩顎部的狀態刀尖彼此會接觸的一對切斷刀等。又，此接觸部，例如可為分別設在夾持工具的兩顎部的橫夾齒與連結部之間的對向面，且在閉合兩顎部的狀態前端部分會接觸的一對突起部等。又，此接觸部，可為設在比兩臂部的連結部還靠手柄側，且在閉合兩顎部的狀態刀尖彼此會接觸的一對切斷刀等。再者，作為此接觸部，例如可用相同於專利文獻1中的止動件等的構成。Further, the contact portion here is conceivable to be in contact with each other in a state in which the two crotch portions are closed, and the contact portion in the relative positional relationship between the two crotch portions in the height direction of the ridge in the state in which the two crotch portions are closed is confined. It is also conceivable that the contact portion is in a state in which the two crotch portions are closed, and the contact portion in which the one crotch portion moves in the other crotch portion is blocked in a state in which the two crotch portions are closed. Further, the contact portion here is, for example, a person who restricts the grip limit of the arm portion 1 by contact, and can be thought of as a stopper that limits the gripping limit. For example, here, the contact portion may correspond to the first region 5 that is in contact with the case where the two jaw portions 4 are closed in the present embodiment. Further, the contact portion may be, for example, a pair of cut surfaces that are provided between the lateral nips of the gripping tool and the joint portion, and that are in contact with each other in a state where the two knuckles are closed. Knife and so on. Further, the contact portion may be, for example, a pair of protrusions which are respectively provided on the opposing faces between the lateral nips of the gripping tools and the connecting portions, and which are in contact with each other at the front end portion of the closed state. Wait. Further, the contact portion may be a pair of cutting blades or the like which are provided on the handle side of the connecting portion of the both arm portions and which are in contact with each other in a state where the two jaw portions are closed. In addition, as the contact portion, for example, a configuration similar to the stopper or the like in Patent Document 1 can be used.
