The pliers include a first assembly including a first handle, a first jaw, and a first workpiece engaging surface. The pliers include a second assembly including a second handle, a second jaw, a second workpiece engaging surface, and a third workpiece engaging surface.

替代性示範性實施例係關於如可在申請專利範圍中大體敘述之其他特徵及特徵的組合。Alternative exemplary embodiments relate to other features and combinations of features as may be generally recited in the scope of the patent application.

較佳實施例之詳細說明 大體參看諸圖，鉗，特定言之鎖定鉗的各種實施例得以展示。鉗包括經由第一樞軸可樞轉地耦接至第二手柄及第二夾爪之第一手柄及第一夾爪。鉗包括在第一及第二夾爪上之相對的工件嚙合表面。大體而言，在本文所述之實施例中，工件嚙合表面中之至少一者可動地耦接至相關聯的夾爪元件，從而允許工件嚙合表面與夾爪之間的相對移動。申請人已發現，與具有固定工件嚙合表面之鉗相比，隨著扭力施加至工件，工件嚙合表面與夾爪之間的相對運動顯著地增加扭力(例如，增加10%-70%或更多)。在一些實施例中，申請人相信，與具有固定工件嚙合表面之鉗相比，本文所論述之設計將在滑動之前施加至工件的扭力增加至少10%-70%，諸如50%、60%、70%、80%、90%、100%，或更多。Detailed description of the preferred embodiment Referring generally to the figures, various embodiments of pliers, and in particular locking pliers, are shown. The pliers includes a first handle and a first jaw pivotally coupled to a second handle and a second jaw via a first pivot. The jaws include opposing workpiece engaging surfaces on the first and second jaws. Generally speaking, in the embodiments described herein, at least one of the workpiece engaging surfaces is movably coupled to the associated jaw element, thereby allowing relative movement between the workpiece engaging surface and the jaws. Applicants have discovered that the relative motion between the workpiece engagement surface and the jaws significantly increases the torsional force (e.g., an increase of 10%-70% or more) as torque is applied to the workpiece compared to pliers with a fixed workpiece engagement surface ). In some embodiments, the applicant believes that the design discussed herein will increase the torque applied to the workpiece before sliding by at least 10%-70%, such as 50%, 60%, compared to pliers with fixed workpiece engaging surfaces 70%, 80%, 90%, 100%, or more.

在本文所述之特定實施例中，工件嚙合表面為定位於上部及下部夾爪上之齒的集合，且附接至下部夾爪之第二樞軸允許定位於下部夾爪上之齒的區段相對於下部夾爪之旋轉。下部齒之此旋轉隨著鉗圍繞工件旋轉而增強所施加的握持力，因此在無滑動之情況下增加施加於工件上的扭力。In the specific embodiment described herein, the workpiece engagement surface is a collection of teeth positioned on the upper and lower jaws, and the second pivot attached to the lower jaws allows the area of the teeth positioned on the lower jaws The segment rotates relative to the lower jaw. This rotation of the lower teeth increases the gripping force applied as the jaws rotate around the workpiece, thus increasing the torque applied to the workpiece without sliding.

在一些實施例中，鉗經由第三樞軸鎖定。鎖定機構允許鉗置放於工件上，且將夾爪鎖定於固定位置中以在不握持手柄之情況下保持握持力。儘管下文之描述適用於鎖定鉗，但在各種實施例中，如本文所論述之可動工件嚙合表面(例如，啟用可動齒之第二樞軸)可用以針對廣泛多種握持工具增強扭力，該等工具諸如非鎖定鉗、扳手等。In some embodiments, the forceps are locked via a third pivot. The locking mechanism allows the jaws to be placed on the work piece, and locks the jaws in a fixed position to maintain the holding force without holding the handle. Although the description below applies to locking pliers, in various embodiments, a movable workpiece engagement surface as discussed herein (eg, a second pivot that enables movable teeth) can be used to enhance torque for a wide variety of gripping tools, etc. Tools such as non-locking pliers, wrenches, etc.

詳言之，傳統鎖定鉗藉由增加所施加之握持力且經由工件之旋轉鎖定握持力而與非鎖定鉗相比允許工件上的更多扭力。鉗在工地為許多功能服務，但常常用以握持工件且在給定方向上旋轉工件。傳統鉗允許操作者「握持」鉗之手柄且圍繞工件旋轉手柄以加緊或鬆開工件。一些鉗鎖定以移除對隨著鉗圍繞工件旋轉而連續地施加握持力的需要。鎖定鉗使操作者能夠設定且施加握持力，上部及下部夾爪接著隨著鉗圍繞工件旋轉而保持所設定之固定位置。In detail, the conventional locking pliers allow more torsional force on the workpiece than the non-locking pliers by increasing the applied holding force and locking the holding force through the rotation of the workpiece. Pliers serve many functions on the job site, but are often used to hold the workpiece and rotate the workpiece in a given direction. Conventional pliers allow the operator to "hold" the handle of the pliers and rotate the handle around the workpiece to tighten or loosen the workpiece. Some pliers lock to remove the need to continuously apply a holding force as the pliers rotate around the workpiece. The locking jaws allow the operator to set and apply a gripping force, and the upper and lower jaws then maintain the set fixed position as the jaws rotate around the workpiece.

在一實施例中，下部夾爪，或下部夾爪之可動面，單獨地釘紮至樞軸。因此，當操作者將扭力施加至工件時，下部夾爪，或下部夾爪之可動面，樞轉以增加鎖定或握持力。下部夾爪，或下部夾爪之可動面，可單獨地旋轉，使得下部夾爪之部分可圍繞不同的樞軸點樞轉。因此，當施加至鉗之力產生工件上的扭力時，下部夾爪，或下部夾爪之可動面，被允許樞轉以增加鎖定力或握持力。手柄上之力藉由下部夾爪之可旋轉可動面產生工件上的扭力，該扭力與藉由無第二樞軸接頭之相同鉗上之相同力所產生的扭力相比大至少10-70%。在一些實施例中，施加於工件上之扭力增加70%或更多。In one embodiment, the lower jaw, or the movable surface of the lower jaw, is separately pinned to the pivot. Therefore, when the operator applies a torsional force to the workpiece, the lower jaw, or the movable surface of the lower jaw, pivots to increase the locking or gripping force. The lower jaw, or the movable surface of the lower jaw, can be rotated independently, so that the part of the lower jaw can pivot around different pivot points. Therefore, when the force applied to the jaws produces a torsional force on the workpiece, the lower jaw, or the movable surface of the lower jaw, is allowed to pivot to increase the locking force or holding force. The force on the handle generates a torsional force on the workpiece by the rotatable movable surface of the lower jaw, which is at least 10-70% greater than the torsional force generated by the same force on the same jaw without a second pivot joint . In some embodiments, the torque applied to the workpiece is increased by 70% or more.

圖1說明鉗10，鉗10具有耦接至第一或上部夾爪14之第一或上部手柄12及耦接至第二或下部夾爪18之第二或下部手柄16。上部手柄12及上部夾爪14經由第一樞軸15耦接至下部手柄16及下部夾爪18，第一樞軸15經組配來打開及閉合夾爪。上部夾爪14及下部夾爪18經組配來打開且在夾爪之間的空間中***工件，並閉合以握持工件，例如夾持工件。上部夾爪14可包括經組配來嚙合工件之第一組齒20。下部夾爪18與上部夾爪14相對，且可包括與上部夾爪14上之第一組齒20相對的第二組齒22及第三組齒24。第二組齒安置於下部夾爪18之第一部分26上，且第三組齒24安置於圍繞第二樞軸30旋轉的第二部分28上。在此組態中，第三組齒24提供槓桿臂，該槓桿臂隨著力施加至上部手柄12及下部手柄16而增加施加至工件之扭力。1 illustrates a forceps 10 having a first or upper handle 12 coupled to a first or upper jaw 14 and a second or lower handle 16 coupled to a second or lower jaw 18. The upper handle 12 and the upper jaw 14 are coupled to the lower handle 16 and the lower jaw 18 via a first pivot 15 that is assembled to open and close the jaw. The upper jaw 14 and the lower jaw 18 are assembled to open and insert the workpiece in the space between the jaws, and close to hold the workpiece, for example, clamp the workpiece. The upper jaw 14 may include a first set of teeth 20 configured to engage the workpiece. The lower jaw 18 opposes the upper jaw 14 and may include a second set of teeth 22 and a third set of teeth 24 opposite the first set of teeth 20 on the upper jaw 14. The second set of teeth is disposed on the first portion 26 of the lower jaw 18, and the third set of teeth 24 is disposed on the second portion 28 that rotates about the second pivot 30. In this configuration, the third set of teeth 24 provides a lever arm that increases the torque applied to the workpiece as force is applied to the upper handle 12 and the lower handle 16.

參看圖1至圖5，呈鎖定鉗10之形式的手工具係根據本發明之一實施例說明。鎖定鉗10包括上部夾爪14及耦接至上部夾爪14之上部手柄12。鎖定鉗10亦包括可動的下部夾爪18，及在第一樞軸15處將上部夾爪14樞轉地耦接至下部夾爪18之下部手柄16。下部手柄16可圍繞第一樞軸15樞轉，以在打開位置與閉合位置(圖1)之間相對於上部夾爪14移動下部夾爪18。上部夾爪14包括與上部手柄12相對之遠端末端32，且下部夾爪18包括與下部手柄16相對之遠端末端34。Referring to FIGS. 1 to 5, a hand tool in the form of a locking pliers 10 is described according to an embodiment of the present invention. The locking jaw 10 includes an upper jaw 14 and an upper handle 12 coupled to the upper jaw 14. The locking jaw 10 also includes a movable lower jaw 18 and a lower handle 16 that pivotally couples the upper jaw 14 to the lower jaw 18 at the first pivot 15. The lower handle 16 is pivotable about the first pivot 15 to move the lower jaw 18 relative to the upper jaw 14 between the open position and the closed position (FIG. 1 ). The upper jaw 14 includes a distal end 32 opposite the upper handle 12 and the lower jaw 18 includes a distal end 34 opposite the lower handle 16.

夾持或擠壓上部手柄12及下部手柄16提供上部夾爪14及下部夾爪18上之夾持力。當施加至手柄12、16之旋轉力變為工件上的扭力時，其迫使工件旋轉且在夾爪14及18上產生摩擦。舉例而言，當手柄12、16經夾持且在順時針方向上旋轉時，順時針扭力施加至工件。扭力使下部夾爪18之第二部分28，包括第三組齒24，歸因於在逆時針方向上之摩擦而在順時針方向上圍繞第二樞軸30樞轉。第二部分28或下部夾爪18之旋轉增加施加至工件之夾持力。藉由此增加之夾持力，操作者可在無滑動或不損失夾持力之情況下在順時針方向上將增加量的扭力施加於工件上。在一些實施例中，扭力之量增加10%、15%、20%、25%、30%、35%、40%、45%、50%、55%、60%、65%、70%或更多。Clamping or pressing the upper handle 12 and the lower handle 16 provides the clamping force on the upper jaw 14 and the lower jaw 18. When the rotational force applied to the handles 12, 16 becomes a torsional force on the workpiece, it forces the workpiece to rotate and creates friction on the jaws 14 and 18. For example, when the handles 12, 16 are clamped and rotated in the clockwise direction, a clockwise torsional force is applied to the workpiece. The torsional force causes the second portion 28 of the lower jaw 18, including the third set of teeth 24, to pivot in a clockwise direction about the second pivot 30 due to friction in the counterclockwise direction. The rotation of the second part 28 or the lower jaw 18 increases the clamping force applied to the workpiece. With this increased clamping force, the operator can apply an increased amount of torque to the workpiece in a clockwise direction without slipping or without loss of clamping force. In some embodiments, the amount of torque is increased by 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70% or more many.

如上文所述，第一樞軸15允許上部手柄12及上部夾爪14至下部手柄16及下部夾爪18之可旋轉耦接。隨著手柄12、16被擠壓或加緊，下部夾爪18相對於上部夾爪14移動以減小界定為上部夾爪14與下部夾爪18之間的區域之工作區域。第一樞軸15為將下部手柄16耦接至上部手柄12之接頭，使得上部手柄12相對於下部手柄16可動以相對於上部夾爪14移動下部夾爪18。換言之，下部手柄16關於上部手柄12樞轉，以增加或減小固定之上部夾爪14的遠端末端32與可動之下部夾爪18之遠端末端34之間的距離D(例如，圖3)。As described above, the first pivot 15 allows the rotatably coupling of the upper handle 12 and upper jaw 14 to the lower handle 16 and lower jaw 18. As the handles 12, 16 are squeezed or tightened, the lower jaw 18 moves relative to the upper jaw 14 to reduce the working area defined as the area between the upper jaw 14 and the lower jaw 18. The first pivot 15 is a joint that couples the lower handle 16 to the upper handle 12 so that the upper handle 12 is movable relative to the lower handle 16 to move the lower jaw 18 relative to the upper jaw 14. In other words, the lower handle 16 pivots about the upper handle 12 to increase or decrease the distance D between the distal end 32 of the fixed upper jaw 14 and the distal end 34 of the movable lower jaw 18 (eg, FIG. 3 ).

在一些實施例中，第二樞軸接頭或第二樞軸30將第三組齒24耦接至下部夾爪18。第二樞軸30接頭允許第三組齒24獨立於第一樞軸接頭15而圍繞第二樞軸30旋轉。在此組態中，下部夾爪18上之第二組齒22可圍繞第一樞軸15樞轉。下部夾爪18上之第三組齒24可圍繞第一樞軸15及第二樞軸30兩者樞轉。當第三組齒24圍繞第二樞軸30旋轉時，工作區域減小，從而增強夾持力。第三組齒減小工作區域之直徑。此減小之區域增加工件上之夾持或握持力，且藉此增加施加至工件的扭力。In some embodiments, the second pivot joint or second pivot 30 couples the third set of teeth 24 to the lower jaw 18. The second pivot 30 joint allows the third set of teeth 24 to rotate about the second pivot 30 independently of the first pivot joint 15. In this configuration, the second set of teeth 22 on the lower jaw 18 can pivot about the first pivot 15. The third set of teeth 24 on the lower jaw 18 can pivot about both the first pivot axis 15 and the second pivot axis 30. When the third set of teeth 24 rotates about the second pivot 30, the working area decreases, thereby enhancing the clamping force. The third set of teeth reduces the diameter of the working area. This reduced area increases the clamping or holding force on the workpiece, and thereby increases the torque applied to the workpiece.

在一些實施例中，各種參數判定第一樞軸15及第二樞軸30之相對位置。舉例而言，鎖定鉗10包括縱向軸線74及高度軸線76。第二樞軸30可沿著高度軸線相對於第一樞軸15間隔，使得第二樞軸30定位於第一樞軸15與下部手柄16中間。此外，第三組齒24可在第二組齒22後方定位。在此組態中，第三組齒24在縱向軸線74之方向上定位於第二組齒22與第一樞軸15之間。In some embodiments, various parameters determine the relative positions of the first pivot 15 and the second pivot 30. For example, the locking forceps 10 includes a longitudinal axis 74 and a height axis 76. The second pivot 30 may be spaced relative to the first pivot 15 along the height axis so that the second pivot 30 is positioned between the first pivot 15 and the lower handle 16. In addition, the third set of teeth 24 may be positioned behind the second set of teeth 22. In this configuration, the third set of teeth 24 is positioned between the second set of teeth 22 and the first pivot 15 in the direction of the longitudinal axis 74.

參看圖3至圖5，上部夾爪14包括藉由平面所界定之工件嚙合表面36，該平面連接定位於上部夾爪14之前部上的第一組齒20之遠端末端32。如所說明，額外的工件嚙合表面38可包括藉由定位於夾爪14之後部處的齒20之遠端末端所界定的額外平面。在所說明實施例中，斜角將工件嚙合表面36連接至上部夾爪14上之額外的工件嚙合表面38。在一些實施例中，工件嚙合表面36及第二夾爪面102可為平行、成銳角，或垂直的。出於本揭示案之目的，除非另有提到，否則工件嚙合表面36包括上部夾爪14上之所有工件嚙合表面。Referring to FIGS. 3 to 5, the upper jaw 14 includes a workpiece engagement surface 36 defined by a plane that connects the distal end 32 of the first set of teeth 20 positioned on the front of the upper jaw 14. As illustrated, the additional workpiece engagement surface 38 may include an additional plane defined by the distal end of the tooth 20 positioned at the rear of the jaw 14. In the illustrated embodiment, the bevel angle connects the workpiece engagement surface 36 to an additional workpiece engagement surface 38 on the upper jaw 14. In some embodiments, the workpiece engagement surface 36 and the second jaw face 102 may be parallel, at an acute angle, or perpendicular. For the purposes of this disclosure, unless otherwise mentioned, the workpiece engagement surface 36 includes all workpiece engagement surfaces on the upper jaw 14.

下部夾爪18包括具有定位於下部夾爪18之前部處之多個齒22的第一部分26，及藉由第二樞軸30樞轉地耦接至第一部分26之第二部分28。如本文所述，此第二樞軸30使第二部分28，包括第三組齒24，能夠旋轉且相對於第一部分26移動。第二部分28自初始位置(圖4中所說明)朝向鄰近於上部手柄12之第二位置相對於第一部分26樞轉(大體在如圖5中所說明之箭頭A的方向上)。該旋轉可為自由的或偏向的。偏向旋轉圍繞第二樞軸30之軸線施加彈簧常數，以使第二部分28返回至初始位置。舉例而言，彈簧可使下部夾爪18之第二部分28旋轉至無所施加扭力的抵靠下部夾爪18之靜止位置(resting position)。當扭力經施加時，夾持力可旋轉彈簧遠離靜止或初始位置且朝向工作區域之後部。The lower jaw 18 includes a first portion 26 having a plurality of teeth 22 positioned at the front of the lower jaw 18, and a second portion 28 pivotally coupled to the first portion 26 by a second pivot 30. As described herein, this second pivot 30 enables the second portion 28, including the third set of teeth 24, to rotate and move relative to the first portion 26. The second portion 28 pivots relative to the first portion 26 from an initial position (illustrated in FIG. 4) toward a second position adjacent to the upper handle 12 (generally in the direction of arrow A as illustrated in FIG. 5). This rotation can be free or biased. The yaw rotation applies a spring constant around the axis of the second pivot 30 to return the second portion 28 to the initial position. For example, the spring can rotate the second portion 28 of the lower jaw 18 to a resting position against the lower jaw 18 without applied torque. When the torsional force is applied, the clamping force can rotate the spring away from the rest or initial position and toward the rear of the work area.

在初始位置中，第二部分28鄰接下部夾爪18上之肩部44。第二部分28包括定位於下部夾爪18之後部末端處的多個齒(例如，第三組齒24)。連接第三組齒24之遠端末端的平面界定第二工件嚙合表面40。如下文更詳細地描述，第二部分28可相對於下部夾爪18之第一部分26樞轉，以使第二工件嚙合表面40相對於上部夾爪14及下部夾爪18上之工件嚙合表面38、40及42的位置及方位變化。工件嚙合表面36、38、40及/或42可為彎曲、平面、抛物線、成角、六邊形的，或包含另一形狀。In the initial position, the second portion 28 abuts the shoulder 44 on the lower jaw 18. The second portion 28 includes a plurality of teeth positioned at the rear end of the lower jaw 18 (eg, a third set of teeth 24). The plane connecting the distal ends of the third set of teeth 24 defines the second workpiece engaging surface 40. As described in more detail below, the second portion 28 can pivot relative to the first portion 26 of the lower jaw 18 so that the second workpiece engagement surface 40 is relative to the workpiece engagement surface 38 on the upper jaw 14 and the lower jaw 18 , 40 and 42 position and orientation changes. Workpiece engagement surfaces 36, 38, 40, and/or 42 may be curved, planar, parabolic, angled, hexagonal, or include another shape.

下部夾爪18包括藉由平面所界定之第二工件嚙合表面40，該平面連接下部夾爪18之第二部分28上的第三組齒120。如上文所解釋，下部夾爪18可包括額外的工件嚙合表面42，或第二工件嚙合表面40可包含整個下部夾爪18。舉例而言，下部夾爪之第一部分26藉由額外之工件嚙合表面42界定平面。額外之工件嚙合表面將下部夾爪18之遠端末端34連接至下部夾爪18之第二部分28所開始處的斜角。在所說明實施例中，斜角將第二工件嚙合表面40定向至下部夾爪18上之額外的工件嚙合表面42。在一些實施例中，第二工件嚙合表面40及額外之工件嚙合表面42可為平行、成銳角，或垂直的。出於本揭示案之目的，第二工件嚙合表面40僅包括可樞轉地耦接(例如，經由第二樞軸30)至下部夾爪18之第二部分28。任何額外之工件嚙合表面42將單獨地識別及區分。The lower jaw 18 includes a second workpiece engagement surface 40 defined by a plane connecting the third set of teeth 120 on the second portion 28 of the lower jaw 18. As explained above, the lower jaw 18 may include an additional workpiece engaging surface 42 or the second workpiece engaging surface 40 may contain the entire lower jaw 18. For example, the first portion 26 of the lower jaw defines the plane by the additional workpiece engaging surface 42. The additional workpiece engagement surface connects the distal end 34 of the lower jaw 18 to the bevel where the second portion 28 of the lower jaw 18 begins. In the illustrated embodiment, the oblique angle directs the second workpiece engagement surface 40 to an additional workpiece engagement surface 42 on the lower jaw 18. In some embodiments, the second workpiece engagement surface 40 and the additional workpiece engagement surface 42 may be parallel, at an acute angle, or perpendicular. For the purposes of this disclosure, the second workpiece engagement surface 40 only includes a second portion 28 that is pivotally coupled (eg, via the second pivot 30) to the lower jaw 18. Any additional workpiece engagement surfaces 42 will be individually identified and distinguished.

舉例而言，第二樞軸30允許第二工件嚙合表面40相對於第二或下部夾爪18移動。第一或上部夾爪14及下部夾爪18界定工作區域(例如，第一夾爪與第二夾爪之間的區域)，該工作區域在力引入工件上之所施加扭力時隨著第二工件嚙合表面40相對於下部夾爪18移動而減小。在一些實施例中，第二工件嚙合表面40可包括整個下部夾爪18，使得在下部夾爪18上不存在額外之工件嚙合表面42。For example, the second pivot 30 allows the second workpiece engaging surface 40 to move relative to the second or lower jaw 18. The first or upper jaw 14 and the lower jaw 18 define a working area (for example, the area between the first jaw and the second jaw), the working area follows the second torque when the force is applied to the workpiece. The workpiece engaging surface 40 moves relative to the lower jaw 18 and decreases. In some embodiments, the second workpiece engaging surface 40 may include the entire lower jaw 18 so that there is no additional workpiece engaging surface 42 on the lower jaw 18.

在其他實施例中，第三工件嚙合表面(例如，額外之工件嚙合表面42)可耦接至下部夾爪18。類似地，第四工件嚙合表面(例如，額外之工件嚙合表面38)可耦接至第一夾爪。在此組態中，在上部夾爪14上存在兩個工件嚙合表面36、38，且在下部夾爪18上存在兩個工件嚙合表面40、42。在一些實施例中，下部夾爪18之第二部分28上的第二工件嚙合表面40相對於第一工件嚙合表面36、第三工件嚙合表面38及第四工件嚙合表面42樞轉。In other embodiments, a third workpiece engaging surface (eg, additional workpiece engaging surface 42) may be coupled to the lower jaw 18. Similarly, a fourth workpiece engaging surface (eg, additional workpiece engaging surface 38) may be coupled to the first jaw. In this configuration, there are two workpiece engagement surfaces 36, 38 on the upper jaw 14 and two workpiece engagement surfaces 40, 42 on the lower jaw 18. In some embodiments, the second workpiece engagement surface 40 on the second portion 28 of the lower jaw 18 pivots relative to the first workpiece engagement surface 36, the third workpiece engagement surface 38, and the fourth workpiece engagement surface 42.

下部夾爪18上之第二工件嚙合表面40可包括可圍繞第二樞軸30樞轉之多個對準齒(例如，第三組齒24)。第三組齒24之長度係在下部夾爪18之第二部分28上的最前與最後齒之間量測。舉例而言，下部夾爪18具有沿著縱向軸線74之縱向長度及沿著高度軸線76之高度。沿著下部夾爪18之第二部分28對準的第三組齒24之長度可為第二夾爪之縱向長度的至少25%。如上文所述，該長度可為下部夾爪18之100%。在一些實施例中，沿著下部夾爪之第三組齒24的長度可為下部夾爪18之長度的30%、35%、40%、45%、50%、55%、60%、65%、70%、75%、80%、85%、90%、95%或100%。The second workpiece engaging surface 40 on the lower jaw 18 may include a plurality of alignment teeth (eg, a third set of teeth 24) that can pivot about the second pivot 30. The length of the third set of teeth 24 is measured between the front and last teeth on the second portion 28 of the lower jaw 18. For example, the lower jaw 18 has a longitudinal length along the longitudinal axis 74 and a height along the height axis 76. The length of the third set of teeth 24 aligned along the second portion 28 of the lower jaw 18 may be at least 25% of the longitudinal length of the second jaw. As mentioned above, this length may be 100% of the lower jaw 18. In some embodiments, the length of the third set of teeth 24 along the lower jaw may be 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65 of the length of the lower jaw 18 %, 70%, 75%, 80%, 85%, 90%, 95% or 100%.

返回至圖1及圖2，鎖定機構46可經組配來相對於下部夾爪18鎖定上部夾爪14之位置。最佳地在圖2中所說明，鎖定鉗10包括可操作以將鉗10保持於閉合或固定位置之鎖定機構46。鎖定機構46包括鎖定連桿部件48及調整部件50(例如，控制匙)。鎖定連桿部件48之第一末端52可滑動地耦接至上部/上部手柄12，且沿著上部/上部手柄12軸向可動。第一末端包括與控制匙或調整部件50之嚙合表面58。隨著調整部件50加緊，耦接至上部手柄12之鎖定連桿部件48移動以增加在上部夾爪14及下部夾爪18處的夾持力。鎖定連桿部件48之第二末端54可在樞軸銷56處樞轉地耦接至下部手柄16。在其他實施例中，鎖定連桿部件48可經由一或多個樞轉連桿部件樞轉地耦接至下部手柄16，或可沿著下部夾爪18直接樞轉。Returning to FIGS. 1 and 2, the locking mechanism 46 may be configured to lock the position of the upper jaw 14 relative to the lower jaw 18. As best illustrated in FIG. 2, the locking jaw 10 includes a locking mechanism 46 operable to hold the jaw 10 in a closed or fixed position. The lock mechanism 46 includes a lock link member 48 and an adjustment member 50 (for example, a control key). The first end 52 of the locking link member 48 is slidably coupled to the upper/upper handle 12 and is axially movable along the upper/upper handle 12. The first end includes an engagement surface 58 with the control key or adjustment member 50. As the adjustment member 50 tightens, the locking link member 48 coupled to the upper handle 12 moves to increase the clamping force at the upper jaw 14 and the lower jaw 18. The second end 54 of the lock link member 48 may be pivotally coupled to the lower handle 16 at the pivot pin 56. In other embodiments, the lock link member 48 may be pivotally coupled to the lower handle 16 via one or more pivot link members, or may pivot directly along the lower jaw 18.

在所說明實施例中，第三樞軸60將經鎖定之下部手柄16連接至經鎖定之下部夾爪18。經由鎖定機構所產生之力傳輸至第三樞軸60，第三樞軸60將力傳輸至下部夾爪18，從而產生工件上的鎖定夾持力。釋放槓桿62在銷64處樞轉地耦接至下部手柄16。釋放槓桿62嚙合鎖定連桿部件48上之波瓣66，以自鎖定或閉合位置釋放鉗10。鎖定連桿部件48可自上部手柄12延伸至下部手柄16且嚙合鎖定機構46，鎖定機構46相對於上部手柄12將下部手柄16鎖定於適當位置以使得下部夾爪18相對於上部夾爪14鎖定。In the illustrated embodiment, the third pivot 60 connects the locked lower handle 16 to the locked lower jaw 18. The force generated by the locking mechanism is transmitted to the third pivot 60, and the third pivot 60 transmits the force to the lower jaw 18, thereby generating a locking clamping force on the workpiece. The release lever 62 is pivotally coupled to the lower handle 16 at the pin 64. The release lever 62 engages the lobe 66 on the locking link member 48 to release the forceps 10 from the locked or closed position. The locking link member 48 can extend from the upper handle 12 to the lower handle 16 and engage a locking mechanism 46 that locks the lower handle 16 in position relative to the upper handle 12 so that the lower jaw 18 is locked relative to the upper jaw 14 .

調整部件50包括在一末端處之嚙合表面58、螺紋柄68，及與嚙合表面58相對的自柄68延伸之凸緣70。調整部件50諸如藉由鑄造、鍛造及其類似者而由金屬整體地形成為單一組件。螺紋柄68係藉由在上部手柄12的與上部夾爪14相對之末端中的螺紋孔69接納。歸因於柄68及孔69之螺紋嚙合，調整部件50可相對於上部手柄12旋轉以在軸向方向上平移調整部件50。The adjustment member 50 includes an engagement surface 58 at one end, a threaded shank 68, and a flange 70 extending from the shank 68 opposite the engagement surface 58. The adjustment member 50 is integrally formed as a single component from metal, such as by casting, forging, and the like. The threaded shank 68 is received by a threaded hole 69 in the end of the upper handle 12 opposite the upper jaw 14. Due to the threaded engagement of the handle 68 and the hole 69, the adjustment member 50 can rotate relative to the upper handle 12 to translate the adjustment member 50 in the axial direction.

在所說明實施例中，凸緣70包括細長開口72。細長開口72可允許工具(例如，螺絲起子)之使用以穿透孔洞且增加施加至鎖定機構46的力。藉由鎖定機構所施加之增加的夾持力可增加施加於工件上之可利用扭力。因此，細長開口72及下部夾爪18之第二部分28的組合可組合以增加施加至工件之扭力。在一些實施例中，扭力可增加10%或更多。藉由凸緣70中之細長開口72及下部夾爪18之可旋轉的第二部分28，與標準鎖定鉗相比，在滑動之前施加至工件之扭力可增加超過20%、25%、30%、40%、50%、55%、60%、65%、70%或更多。與標準鎖定鉗相比，具有細長開口72之凸緣70及可旋轉的第二部分28可將滑動之前施加至工件之扭力增加80%、90%、100%、125%、150%、175%或更多。In the illustrated embodiment, the flange 70 includes an elongated opening 72. The elongated opening 72 may allow the use of a tool (eg, a screwdriver) to penetrate the hole and increase the force applied to the locking mechanism 46. The increased clamping force applied by the locking mechanism can increase the available torque applied to the workpiece. Therefore, the combination of the elongated opening 72 and the second portion 28 of the lower jaw 18 can be combined to increase the torque applied to the workpiece. In some embodiments, the torque can be increased by 10% or more. With the elongated opening 72 in the flange 70 and the rotatable second portion 28 of the lower jaw 18, the torque applied to the workpiece before sliding can be increased by more than 20%, 25%, 30% compared to standard locking pliers , 40%, 50%, 55%, 60%, 65%, 70% or more. Compared to standard locking pliers, the flange 70 with elongated opening 72 and the rotatable second portion 28 can increase the torque applied to the workpiece before sliding by 80%, 90%, 100%, 125%, 150%, 175% Or more.

移動嚙合表面58與鎖定連桿部件48之第一末端52之間的嚙合使鎖定連桿部件48關於第二樞軸銷56移動，且調整夾爪14、18在閉合時施加於工件上的夾持力。當下部手柄16處於閉合位置中時，改變調整部件50相對於上部手柄12之位置改變了上部夾爪14與下部夾爪18之間的距離。在一些實施例中，鎖定鉗10進一步包括耦接於下部夾爪18與上部手柄12之間的彈簧74。彈簧74使下部夾爪18朝向打開位置偏向，因此允許工件上之夾持力的釋放。當釋放槓桿62被推動且彈簧74嚙合時，工件上之夾持力被釋放，且鉗10可相對於工件移除或重設。The engagement between the moving engagement surface 58 and the first end 52 of the lock link member 48 causes the lock link member 48 to move about the second pivot pin 56 and adjusts the clamps that the jaws 14, 18 apply to the workpiece when closed Hold on. When the lower handle 16 is in the closed position, changing the position of the adjustment member 50 relative to the upper handle 12 changes the distance between the upper jaw 14 and the lower jaw 18. In some embodiments, the locking forceps 10 further includes a spring 74 coupled between the lower jaw 18 and the upper handle 12. The spring 74 biases the lower jaw 18 toward the open position, thus allowing the release of the clamping force on the workpiece. When the release lever 62 is pushed and the spring 74 is engaged, the clamping force on the workpiece is released, and the jaws 10 can be removed or reset relative to the workpiece.

參看圖4及圖5，針對夾爪14、18之遠端末端32、34之間的任何特定距離D，當可動夾爪18之第二部分28處於其初始位置中時(圖4)，第一夾爪面94、第二夾爪面102及第三夾爪面134界定工作區域或第一夾持直徑Φ1。當下部夾爪18及上部夾爪14藉由夾持力嚙合工件且施加扭力時，第三組齒24圍繞第二樞軸30接頭樞轉，使得自第二樞軸30接頭至工件之半徑隨著施加至手柄的扭力增加而增加。Referring to FIGS. 4 and 5, for any particular distance D between the distal ends 32, 34 of the jaws 14, 18, when the second portion 28 of the movable jaw 18 is in its initial position (FIG. 4), the first A clamping jaw surface 94, a second clamping jaw surface 102 and a third clamping jaw surface 134 define a working area or a first clamping diameter Φ1. When the lower jaw 18 and the upper jaw 14 engage the workpiece by the clamping force and apply a torsional force, the third set of teeth 24 pivots around the second pivot 30 joint, so that the radius from the second pivot 30 joint to the workpiece The torque applied to the handle increases.

第一夾持直徑Φ1為與第一夾爪面94、第二夾爪面102及第三夾爪面134(例如，工件嚙合表面)中之每一者相切的圓之直徑。當可動夾爪18之第二部分28自圖4中所說明之初始位置樞轉至圖5中所說明的樞轉位置時，第一夾爪面94、第二夾爪面102及第三夾爪面134界定小於第一夾持直徑Φ1之第二夾持直徑Φ2，而不會使夾爪14、18之遠端末端32、34之間的距離D變化。在所說明實施例中，第一夾持直徑Φ1與第二夾持直徑Φ2之間的差大於1.58毫米。在一些實施例中，第一夾持直徑Φ1與第二夾持直徑Φ2之間的差可大於1.75毫米。The first clamping diameter Φ1 is the diameter of a circle that is tangent to each of the first clamping jaw face 94, the second clamping jaw face 102, and the third clamping jaw face 134 (eg, workpiece engagement surface). When the second portion 28 of the movable jaw 18 pivots from the initial position illustrated in FIG. 4 to the pivot position illustrated in FIG. 5, the first jaw surface 94, the second jaw surface 102, and the third jaw The claw surface 134 defines a second clamping diameter Φ2 that is smaller than the first clamping diameter Φ1 without changing the distance D between the distal ends 32, 34 of the clamping jaws 14, 18. In the illustrated embodiment, the difference between the first clamping diameter Φ1 and the second clamping diameter Φ2 is greater than 1.58 mm. In some embodiments, the difference between the first clamping diameter Φ1 and the second clamping diameter Φ2 may be greater than 1.75 mm.

在操作中，鎖定鉗10以上部夾爪14及下部夾爪18處於閉合位置中且以下部手柄16處於閉合位置中開始，如圖1中所示。如上文所論述，使用者可在手柄12、16藉由旋轉調整部件50而閉合(使可動之下部夾爪18圍繞第五銷142樞轉)的同時調整夾爪14、18之遠端末端32、34之間的距離D。下部手柄16接著關於上部手柄12打開，從而進一步增加距離D。在夾爪14、18處於打開位置中之情況下(例如，圖3及圖4)，使用者圍繞工件定位夾爪14、18，且接著朝向上部手柄12樞轉下部手柄16以朝向閉合位置移動下部夾爪18。In operation, the locking jaw 10 begins with the upper jaw 14 and lower jaw 18 in the closed position and the lower handle 16 in the closed position, as shown in FIG. 1. As discussed above, the user can adjust the distal end 32 of the jaws 14, 18 while the handles 12, 16 are closed by rotating the adjustment member 50 (to pivot the movable lower jaw 18 about the fifth pin 142) , The distance D between 34. The lower handle 16 is then opened with respect to the upper handle 12, thereby further increasing the distance D. With the jaws 14, 18 in the open position (e.g., FIGS. 3 and 4), the user positions the jaws 14, 18 around the workpiece and then pivots the lower handle 16 toward the upper handle 12 to move toward the closed position The lower gripper 18.

當夾爪14、18閉合且鎖定於工件上時，使用者可將力施加至手柄12、16以試驗且旋轉工件。此力使可動夾爪18之第二部分28在箭頭A之方向上自初始位置(圖4)樞轉至第二旋轉位置(圖5)，藉此減小夾爪14、18的夾持直徑(例如，至夾持直徑Φ2)。夾持直徑之此減小有利地增加施加至工件之夾持力且增強夾爪14、18的握持力。因此，鎖定鉗10在較高的所施加扭力下抵抗工件上之滑動。When the jaws 14, 18 are closed and locked on the workpiece, the user can apply force to the handles 12, 16 to test and rotate the workpiece. This force causes the second portion 28 of the movable jaw 18 to pivot from the initial position (Figure 4) to the second rotational position (Figure 5) in the direction of arrow A, thereby reducing the clamping diameter of the jaws 14, 18 (For example, to the clamping diameter Φ2). This reduction in clamping diameter advantageously increases the clamping force applied to the workpiece and enhances the gripping force of the jaws 14,18. Therefore, the locking pliers 10 resist sliding on the workpiece at a higher applied torque.

舉例而言，依據ASME Standard B107.24，章節5.2.4(「the jaw grip test(夾爪握持力測試)」)之夾爪握持力測試對體現本發明之態樣的鎖定鉗實行。在夾爪握持力測試期間，鎖定鉗經夾持至圓鋼心軸上，其中初始夾持預負載處於30磅與35磅之間。在鎖定鉗固定於適當位置之情況下，心軸以一度每秒之速率旋轉。最大扭力係恰好在心軸滑動且開始相對於夾爪旋轉之前量測。在一些實施例中，鉗在大於212英尺磅，特定言之213-480英尺磅且更特定言之233至380英尺磅之夾爪握持力測試下達成最大扭力。在一些實施例中，鉗在至少300英尺磅之夾爪握持力測試下達成最大扭力。在一些實施例中，鉗在至少380英尺磅之夾爪握持力測試下達成最大扭力。在一些實施例中，鉗在至少400英尺磅之夾爪握持力測試下達成最大扭力。在一些實施例中，鉗在至少480英尺磅之夾爪握持力測試下達成最大扭力。For example, according to ASME Standard B107.24, section 5.2.4 ("the jaw grip test ("the jaw grip test")), the gripping force test of the gripper is performed on the locking pliers embodying the aspect of the present invention. During the gripping force test of the clamping jaws, the locking jaws were clamped onto a round steel mandrel with an initial clamping preload between 30 and 35 pounds. With the locking jaws fixed in place, the mandrel rotates at a rate of one degree per second. The maximum torque is measured just before the mandrel slides and begins to rotate relative to the jaws. In some embodiments, the pliers achieve maximum torque under a gripper grip test of greater than 212 foot pounds, specifically 213-480 foot pounds, and more specifically 233 to 380 foot pounds. In some embodiments, the jaws achieve maximum torque under a gripping force test of at least 300 foot pounds of jaws. In some embodiments, the jaws achieve maximum torque under a gripping force test of at least 380 foot pounds of jaws. In some embodiments, the pliers achieve a maximum torque under a gripping force test of at least 400 foot pounds. In some embodiments, the pliers achieve maximum torque under a gripping force test of at least 480 foot pounds.

圖6至圖7說明具有上部夾爪102及下部夾爪104之鎖定鉗100的實施例。第二夾爪104包括下部夾爪104上之所有齒120及整個下部工件嚙合表面108。下部夾爪104因此可圍繞第一樞軸110及第二樞軸130關於上部夾爪102旋轉。在此實施例中，整個下部夾爪104可圍繞第一樞軸110及第二樞軸130兩者樞轉。6-7 illustrate an embodiment of a locking jaw 100 having an upper jaw 102 and a lower jaw 104. The second jaw 104 includes all teeth 120 on the lower jaw 104 and the entire lower workpiece engaging surface 108. The lower jaw 104 can thus rotate about the first jaw 110 and the second pivot 130 about the upper jaw 102. In this embodiment, the entire lower jaw 104 can pivot about both the first pivot 110 and the second pivot 130.

當力經施加以閉合手柄112、114時，鉗100圍繞工件118閉合。歸因於鉗100之機械優點，在工件118上存在較大的所得夾持力，例如夾爪102、104之間的壓縮力。另外，當使用者將力施加至閉合或經鎖定鉗100之手柄112、114時，移動夾爪104進一步加倍工件118上的所得壓縮夾持力。當鉗100上部夾爪102及下部夾爪104閉合或嚙合於工件118上時，工作區域122界定工件118可配合於作用工件嚙合表面106、108之間的最大第一直徑124。隨著扭力藉由使用者施加至手柄，第一直徑124減小至第二直徑126(圖7中所示)。When force is applied to close the handles 112, 114, the jaws 100 close around the workpiece 118. Due to the mechanical advantages of the pliers 100, there is a large resulting clamping force on the workpiece 118, such as the compressive force between the clamping jaws 102, 104. In addition, when the user applies a force to the handles 112, 114 of the closed or locked jaws 100, the moving jaw 104 further doubles the resulting compressed clamping force on the workpiece 118. When the upper jaw 102 and the lower jaw 104 of the jaw 100 are closed or engaged on the workpiece 118, the working area 122 defines a maximum first diameter 124 that the workpiece 118 can fit between the active workpiece engagement surfaces 106, 108. As the torque is applied to the handle by the user, the first diameter 124 decreases to the second diameter 126 (shown in FIG. 7).

上部夾爪102包含上部工件表面106，包括偏移斜角之齒的兩個平面。下部夾爪104包括具有類似組態之下部工件嚙合表面108(例如，偏移斜角之齒的兩個平面)。在此組態中，下部工件嚙合表面108在下部夾爪104上圍繞樞軸130旋轉作為單一單元。如所說明，下部工件嚙合表面108在下部夾爪104上圍繞第一樞軸110相對於上部夾爪102旋轉。當上部手柄112及下部手柄114朝向彼此移動(例如，夾持力經施加)時，上部夾爪102相對於下部夾爪104移動，從而產生工件118上之夾持力116。上部工件表面106包含第一組齒119。如上文所述，下部工件嚙合表面108包括單一可旋轉第二組齒120的整個長度。下部工件嚙合表面108係沿著下部夾爪104自最前至最後齒量測。如圖6至圖7中所說明及上文所述，可旋轉之下部工件嚙合表面108的長度可包含整個下部夾爪102。儘管說明為在下部夾爪104上，但可旋轉之工件嚙合表面可類似地安置於上部夾爪102上。The upper jaw 102 includes an upper workpiece surface 106, including two planes offset by beveled teeth. The lower jaw 104 includes a lower workpiece engaging surface 108 having a similar configuration (eg, two planes offset by beveled teeth). In this configuration, the lower workpiece engagement surface 108 rotates about the pivot 130 on the lower jaw 104 as a single unit. As illustrated, the lower workpiece engagement surface 108 rotates relative to the upper jaw 102 on the lower jaw 104 about the first pivot 110. When the upper handle 112 and the lower handle 114 move toward each other (eg, a clamping force is applied), the upper jaw 102 moves relative to the lower jaw 104, thereby generating a clamping force 116 on the workpiece 118. The upper workpiece surface 106 contains a first set of teeth 119. As described above, the lower workpiece engagement surface 108 includes the entire length of a single rotatable second set of teeth 120. The lower workpiece engaging surface 108 is measured along the lower jaw 104 from the front to the end of the teeth. As illustrated in FIGS. 6-7 and described above, the length of the rotatable lower workpiece engagement surface 108 may include the entire lower jaw 102. Although illustrated as being on the lower jaw 104, the rotatable workpiece engagement surface can be similarly placed on the upper jaw 102.

當夾持力116散佈於工件118上時，藉由上部夾爪102及下部夾爪104所包圍之工作區域122藉由所施加的夾持力減小且變形以產生工件之第一直徑124。如圖7中所說明，隨著工件旋轉，工作區域122隨著下部夾爪104在A之方向上旋轉而減小且將較大之夾持力116施加於工件118上。此增加之夾持力116可產生工件118中的第二直徑126。隨著工件118經歷扭力，摩擦使距離128縮小，直至第二夾爪接觸上部手柄112且最大化夾持力為止。舉例而言，比較圖6中之距離128與圖7中的旋轉距離。When the clamping force 116 is spread on the workpiece 118, the working area 122 surrounded by the upper jaw 102 and the lower jaw 104 is reduced and deformed by the applied clamping force to produce the first diameter 124 of the workpiece. As illustrated in FIG. 7, as the workpiece rotates, the working area 122 decreases as the lower jaw 104 rotates in the direction of A and applies a larger clamping force 116 to the workpiece 118. This increased clamping force 116 can produce a second diameter 126 in the workpiece 118. As the workpiece 118 experiences torsional force, friction reduces the distance 128 until the second jaw contacts the upper handle 112 and maximizes the clamping force. For example, compare the distance 128 in FIG. 6 with the rotation distance in FIG. 7.

圖8至圖9說明具有可旋轉表面之鉗200的另一實施例。圖8至圖9之實施例與圖1至圖5之實施例實質上相同，除了所描述之差異以外。與鉗10之設計對比，鉗200之第二夾爪部分216具有加厚的第二夾爪面218以增強將夾持力施加於工件220上之區域。8 to 9 illustrate another embodiment of a jaw 200 having a rotatable surface. The embodiments of FIGS. 8 to 9 are substantially the same as the embodiments of FIGS. 1 to 5 except for the differences described. In contrast to the design of the jaw 10, the second jaw portion 216 of the jaw 200 has a thickened second jaw surface 218 to enhance the area where the clamping force is applied to the workpiece 220.

鉗200包括經由第一樞軸212耦接之上部夾爪202及下部夾爪204。下部夾爪204包括夾爪面206及與夾爪面206整體形成之第二部分208，且可圍繞第二樞軸209圍繞下部夾爪204樞轉。下部夾爪204在第一樞軸212處可樞轉地釘紮至上部手柄210，且在第三樞軸處可樞轉地釘紮至下部手柄214。The jaw 200 includes an upper jaw 202 and a lower jaw 204 coupled via a first pivot 212. The lower jaw 204 includes a jaw face 206 and a second portion 208 integrally formed with the jaw face 206, and can pivot about the second jaw 204 around the lower jaw 204. The lower jaw 204 is pivotally pinned to the upper handle 210 at the first pivot 212 and pivotally pinned to the lower handle 214 at the third pivot.

鉗200包括具有加厚之第二夾爪面218的第二夾爪部分216。第二夾爪部分216可旋轉地耦接(例如，經由第二樞軸209)至下部夾爪204。The jaw 200 includes a second jaw portion 216 having a thickened second jaw face 218. The second jaw portion 216 is rotatably coupled (eg, via the second pivot 209) to the lower jaw 204.

當鉗200圍繞工件220閉合時，夾持力222基於手柄之槓桿作用而產生。由於加厚之第二夾爪面218，此力散佈至工件220之較大區域以防止滑動且更均勻地散佈握持力。隨著扭力施加至工件220(例如，在上部手柄210及下部手柄214處之旋轉力)，第二夾爪部分216在方向224上樞轉。第二夾爪部分216在方向224上之移動朝向上部夾爪202及上部手柄210旋轉。此旋轉減小第二夾爪部分216與上部夾爪202之間的工作區域226。減小之工作區域226產生工件220上之增加的夾持力，以在工件220之滑動之前增加所施加之扭力的量。When the clamp 200 is closed around the workpiece 220, the clamping force 222 is generated based on the lever action of the handle. Due to the thickened second jaw surface 218, this force is spread to a larger area of the workpiece 220 to prevent slippage and spread the grip more evenly. As a torsional force is applied to the workpiece 220 (eg, rotational force at the upper handle 210 and the lower handle 214), the second jaw portion 216 pivots in the direction 224. The movement of the second jaw portion 216 in the direction 224 rotates toward the upper jaw 202 and the upper handle 210. This rotation reduces the working area 226 between the second jaw portion 216 and the upper jaw 202. The reduced working area 226 produces an increased clamping force on the workpiece 220 to increase the amount of torque applied before the workpiece 220 slides.

圖10說明鉗300之另一實施例。鉗300與如上文所述之鉗10、100及200實質上相同或類似，除了所描述之差異以外。與鉗10、100及200之設計對比，上部手柄306及下部手柄314圍繞中央軸桿440夾持。另外，上部夾爪302經由長橢圓形接頭344耦接至上部手柄，長橢圓形接頭344允許上部夾爪302在夾爪未鎖定時釋放工件上之夾持力，但在夾爪經鎖定時將相同或實質上相同的夾持力施加於工件上。FIG. 10 illustrates another embodiment of the forceps 300. The forceps 300 are substantially the same or similar to the forceps 10, 100, and 200 as described above, except for the differences described. In contrast to the designs of the pliers 10, 100, and 200, the upper handle 306 and the lower handle 314 clamp around the central shaft 440. In addition, the upper jaw 302 is coupled to the upper handle via an oblong joint 344. The oblong joint 344 allows the upper jaw 302 to release the clamping force on the workpiece when the jaw is not locked, but when the jaw is locked The same or substantially the same clamping force is applied to the workpiece.

上部夾爪302具有第一組齒(例如，齒302a及302b)。下部夾爪304具有兩個部段，可旋轉部段306及夾持部段308。可旋轉部段306圍繞樞軸330夾持且旋轉，且夾持部段308引起夾持力。兩個部段圍繞樞軸315旋轉。齒304a係在可旋轉部段306上。齒304b係在夾持部段308上。上部夾爪302上之齒302a及302b(例如，第一組齒)可組合為上部工件嚙合表面。可圍繞樞軸315旋轉之齒304b界定第二工件嚙合表面。下部夾爪包括齒304a，齒304a可圍繞兩個點(樞軸315及樞軸330)樞轉，從而界定第三工件嚙合表面。齒304a之旋轉減小工作直徑，且隨著扭力施加至工件而增加夾持力。The upper jaw 302 has a first set of teeth (eg, teeth 302a and 302b). The lower jaw 304 has two sections, a rotatable section 306 and a clamping section 308. The rotatable section 306 clamps and rotates about the pivot 330, and the clamping section 308 causes a clamping force. The two sections rotate about the pivot 315. The teeth 304a are attached to the rotatable section 306. The teeth 304b are attached to the clamping section 308. The teeth 302a and 302b (eg, the first set of teeth) on the upper jaw 302 may be combined into an upper workpiece engaging surface. The teeth 304b that can rotate about the pivot 315 define a second workpiece engaging surface. The lower jaw includes teeth 304a that can pivot about two points (pivot 315 and pivot 330) to define a third workpiece engaging surface. The rotation of the teeth 304a reduces the working diameter and increases the clamping force as the torque is applied to the workpiece.

圖11說明根據另一實施例之一對鉗400。圖11中所說明之鉗400與如上文所述之鉗10、100、200及300相同或類似，具有下文所述的差異。與鉗10之設計對比，第二夾爪面406彎曲以增強旋轉弧。彎曲形狀之構造使第二夾爪面406之肩部能夠自不同的第一位置旋轉通過減小工件區域之旋轉弧且進入鄰接上部手柄406之不同的第二位置。FIG. 11 illustrates one pair of pliers 400 according to another embodiment. The pliers 400 illustrated in FIG. 11 are the same as or similar to the pliers 10, 100, 200, and 300 as described above, with the differences described below. In contrast to the design of the forceps 10, the second jaw face 406 is curved to enhance the rotation arc. The configuration of the curved shape enables the shoulder of the second jaw surface 406 to rotate from a different first position by reducing the rotation arc of the workpiece area and into a different second position adjacent to the upper handle 406.

鉗400包括上部夾爪402及下部夾爪404，各自具有兩個單獨組之齒。上部夾爪402之上部組的齒或上部工件嚙合表面包括齒402a及402b。下部夾爪包括兩個不同組之齒404a及404b。齒404a圍繞第一樞軸15及第二樞軸30旋轉。齒404b僅圍繞第一樞軸15旋轉。如所說明，齒402a、402b、404a、404b以鈍角耦接，但可為成銳角、平行或彎曲的。組合齒402a、402b、404a、404b與可旋轉齒404a之總體形狀增加所施加的夾持力。The forceps 400 includes an upper jaw 402 and a lower jaw 404, each having two separate sets of teeth. The upper set of teeth or upper workpiece engaging surface of upper jaw 402 includes teeth 402a and 402b. The lower jaw includes two different sets of teeth 404a and 404b. The teeth 404a rotate around the first pivot 15 and the second pivot 30. The tooth 404b only rotates around the first pivot 15. As illustrated, the teeth 402a, 402b, 404a, 404b are coupled at an obtuse angle, but can be acute, parallel, or curved. The overall shape of the combined teeth 402a, 402b, 404a, 404b and rotatable teeth 404a increases the clamping force applied.

圖12說明根據另一實施例之鎖定鉗500。鎖定鉗500與如上文所述之鉗10實質上相同或類似，除了所描述之差異以外。與鉗10之設計對比，鉗500之齒不旋轉。實情為，鉗500之齒沿著斜面平移以減小工件上的工作區域。FIG. 12 illustrates a locking forceps 500 according to another embodiment. The locking forceps 500 are substantially the same or similar to the forceps 10 as described above, except for the differences described. In contrast to the design of pliers 10, the teeth of pliers 500 do not rotate. In fact, the teeth of the pliers 500 are translated along the inclined plane to reduce the working area on the workpiece.

鉗500包括上部夾爪502及下部夾爪504，各自具有兩個單獨組之齒。上部夾爪502包括可平移之齒502a及502b。下部夾爪包括可平移之齒504a及504b。如所說明，齒502a、502b、504a、504b以鈍角耦接。在一些實施例中，齒可為彈簧加載或偏向的，使得當使用者在手柄處提供旋轉力506且齒將扭力提供至工件508時，齒平移或滑動。舉例而言，齒可沿斜坡平移向上，如藉由箭頭510所指示。此平移使齒能夠減小工件508上之直徑且增加夾持力。箭頭510說明在扭力減小工作區域(藉由箭頭512所說明)且齒平移時齒可平移之方向。當施加旋轉負載506時，此平移增加工件508上之夾持力且減小鎖定鉗500經歷的滑動。The forceps 500 includes an upper jaw 502 and a lower jaw 504, each having two separate sets of teeth. The upper jaw 502 includes translatable teeth 502a and 502b. The lower jaw includes translatable teeth 504a and 504b. As illustrated, the teeth 502a, 502b, 504a, 504b are coupled at an obtuse angle. In some embodiments, the teeth may be spring-loaded or biased, such that when the user provides rotational force 506 at the handle and the teeth provide torque to the workpiece 508, the teeth translate or slide. For example, the teeth can be translated upward along the slope, as indicated by arrow 510. This translation enables the teeth to reduce the diameter on the workpiece 508 and increase the clamping force. Arrow 510 illustrates the direction in which the teeth can translate when the torque is reduced in the work area (illustrated by arrow 512) and the teeth are translated. When a rotational load 506 is applied, this translation increases the clamping force on the workpiece 508 and reduces the slippage experienced by the locking jaw 500.
