Description

切刀用之替換刀刃及切刀 Replacement blade and cutter for cutter

本發明係關於一種切刀用之替換刀刃及切刀。 The invention relates to a replacement blade and a cutter for a cutter.

一直以來，有人提出了更換替換刀刃之切刀。例如，日本專利特開2008-229077號公報所公開之剪切小刀，其具有可在固定切刀刃的同時移動自如的設置於盒內的滑塊。該滑塊包括滑塊主體和能夠在該滑塊主體之間夾入切刀刃而設置之按壓構件。此外，滑塊可藉由進行規定操作來卸下切刀刃。該日本專利特開2008-229077號公報中之剪切小刀的構成為，在卸下切刀刃時，需要對滑塊進行規定操作，故而即使從盒中取出了滑塊和切刀刃，切刀刃亦不會出現不慎脫落這種問題。 For a long time, someone has proposed to replace the cutter with a replacement blade. For example, the cutting knife disclosed in Japanese Patent Application Laid-Open No. 2008-229077 has a slider provided in a box that can move freely while fixing the cutting blade. The slider includes a slider body and a pressing member that can sandwich a cutting blade between the slider body. In addition, the slider can remove the cutting blade by performing prescribed operations. The cutting knife in the Japanese Patent Laid-Open No. 2008-229077 is configured to require a predetermined operation on the slider when removing the cutting blade. Therefore, even if the slider and the cutting blade are removed from the box, the cutting blade is not There will be a problem of accidentally falling off.

例如，日本專利特開2010-264004號公報中所公開之剪切小刀具備切刀主體、具有切刃之切刀構件和對切斷對象物以恒定壓力按壓切刃之施力構件。施力構件使用的係配置在切刃相反一側的板簧等。如此構成之剪切小刀可保持恒定之按壓力，並可使進行裁切操作時之操作性保持穩定。 For example, the cutting knife disclosed in Japanese Patent Laid-Open No. 2010-264004 includes a knife body, a knife member having a cutting edge, and an urging member that presses the cutting edge with a constant pressure on the cutting object. The urging member uses a leaf spring or the like arranged on the opposite side of the cutting blade. The shearing knife constructed in this way can maintain a constant pressing force and can maintain stable operability during cutting operations.

然而，上述之剪切小刀可利用覆蓋部分刃體之滑塊來對替換刀刃進行更換，而大部分刃體直至被收納在切刀主體為止之時間段內係露出的，故而有時在替換刀刃之更換操作過程中，使用者便會觸碰到刃體。 However, the above-mentioned shearing knife can be replaced by a slider covering part of the blade body, and most of the blade body is exposed during the period of time until it is stored in the main body of the cutter, so sometimes the blade is replaced. During the replacement operation, the user will touch the blade.

本發明有鑒於以上問題，目的係提供一種在進行替換刀刃之更換操作時，可降低接觸到替換刀刃之刀刃的可能性之切刀用替換刀刃和具備該替換刀刃之切刀。 In view of the above problems, the purpose of the present invention is to provide a replacement blade for a cutter that can reduce the possibility of contact with the blade of the replacement blade and a cutter provided with the replacement blade during the replacement operation of the replacement blade.

本發明之切刀用替換刀刃的特徵在於，具備具有卡合部的托盤和刃體，該刃體具有前後移動自如地被收納於前述托盤上且前述卡合部所卡合之被卡合部；前述卡合部與前述被卡合部可拆裝地相卡合。 The replacement blade for a cutter of the present invention is characterized by comprising a tray having an engaging portion and a blade body, the blade body having an engaged portion that is movably stored on the tray and engaged with the engaging portion ; The engaging portion and the engaging portion are detachably engaged with each other.

本發明之切刀的特徵在於，具備拆裝自如地收納上述切刀用替換刀刃之主體盒，並形成前述可進出之刃體。 The cutter of the present invention is characterized in that it has a main body case that detachably accommodates the replacement blade for the cutter, and forms the blade body that can be moved in and out.

根據本發明，可提供對替換刀刃進行更換操作時，可降低接觸到替換刀刃之刀刃的可能性之切刀用替換刀刃和具備該替換刀刃之切刀。 According to the present invention, it is possible to provide a replacement blade for a cutting knife and a cutting knife provided with the replacement blade that can reduce the possibility of contacting the blade of the replacement blade when the replacement operation is performed on the replacement blade.

尾端蓋40從收納有替換刀刃20和滑塊50之主體盒30之後端，拆裝自如地安裝在開口承托部35，從而作為蓋子來起作用。尾端蓋40被形成為，其左右寬度比主體盒30要窄(參照圖6)。尾端蓋40在前方側具有前方開口部41。在尾端蓋40之後方側，形成有貫穿左右之橢圓形通孔42。此外，為使得尾端蓋40之後端面40d在側面視圖中，在與通孔42之間的位置上形成的壁厚大致相同，而形成為沿通孔42內周邊形狀的橢圓圓弧狀(參照圖5)。在通孔42之內壁部421上，貫穿後端面40d側的兩個通孔422設置在上下方。 The end cap 40 is detachably attached to the opening receiving portion 35 from the rear end of the main body box 30 in which the replacement blade 20 and the slider 50 are housed, and functions as a cap. The end cap 40 is formed so that its left-right width is narrower than that of the main box 30 (refer to FIG. 6). The tail end cap 40 has a front opening 41 on the front side. On the rear side of the end cap 40, an elliptical through hole 42 penetrating the left and right is formed. In addition, in order to make the rear end face 40d of the end cap 40 in a side view, the wall thickness formed at the position between the through hole 42 is substantially the same, and it is formed in an elliptical arc shape along the inner periphery of the through hole 42 (refer to Figure 5). In the inner wall portion 421 of the through hole 42, two through holes 422 penetrating the rear end surface 40d side are provided above and below.

在前方開口部41之內壁，在右側之導面41b和左側之導面41a上，形成有各自向前後方向延伸設置之凸狀導軌43a、43b。導軌43a於上下方並設有兩個，導軌43b亦於上下方並設有兩個。此外，在右側之導面41b，在導軌43b之前方側，形成有與開口承托部35右側之導槽351b、351c之卡止凹部352卡合之凸圓弧狀卡合凸部431。同樣，在左側之導面41a，在導軌43a之前方側，形成有與開口承托部35左側之導槽351a的卡止凹部352卡合的未圖示的凸圓弧狀卡合凸部。因此，藉由右側之導軌43b被導槽351b、351c所導引，而左側之導軌43a被導槽351a所導引，從而尾端蓋40從後方被安裝在主體盒30上。 On the inner wall of the front opening 41, on the right side guide surface 41b and the left side guide surface 41a, there are formed convex guide rails 43a, 43b each extending in the front and rear directions. Two guide rails 43a are provided above and below, and two guide rails 43b are also provided above and below. In addition, on the right guide surface 41b, on the front side of the guide rail 43b, there is formed a convex arc-shaped engagement protrusion 431 that engages with the locking recesses 352 of the guide grooves 351b and 351c on the right side of the opening receiving portion 35. Similarly, on the guide surface 41a on the left side, on the front side of the guide rail 43a, there is formed a convex arc-shaped engagement protrusion not shown that engages with the locking recess 352 of the guide groove 351a on the left side of the opening receiving portion 35. Therefore, the right rail 43b is guided by the guide grooves 351b and 351c, and the left rail 43a is guided by the guide groove 351a, so that the end cap 40 is mounted on the main box 30 from the rear.

尾端蓋40完全被安裝在主體盒30時，卡合凸部431與卡止凹部352相卡合。為此，在獲得安裝有尾端蓋40之卡固感的同時，可防止尾端蓋40不慎脫落。 When the end cap 40 is completely installed in the main box 30, the engaging convex portion 431 engages with the engaging concave portion 352. For this reason, while obtaining the securing feeling of the end cap 40 installed, the end cap 40 can be prevented from accidentally falling off.

在尾端蓋40之頂面形成有安裝有鎖定構件90之呈矩形凹陷之鍃孔部44。鍃孔部44在其底部，於四個角之角部具有安裝孔441，在大致中央位置上具有與安裝孔441相比，敞開面積稍大之鎖定銷貫通孔442。安裝孔441和鎖定銷貫通孔442形成為向尾端蓋40之左右方向延伸之大致為矩形之長孔。此外，在鍃孔部44底部上之左右方向之大致中央位置，在夾持鎖定銷貫通孔442之前側和後側，形成有卡合凸起443。 The top surface of the end cap 40 is formed with a rectangular recessed hole 44 in which the locking member 90 is installed. The hole 44 has a mounting hole 441 at the bottom of the four corners, and a lock pin through hole 442 with a slightly larger opening area than the mounting hole 441 at a substantially central position. The mounting hole 441 and the lock pin through hole 442 are formed as a substantially rectangular long hole extending in the left-right direction of the end cap 40. In addition, at approximately the center position in the left-right direction on the bottom of the hole portion 44, engagement protrusions 443 are formed on the front and rear sides of the clamping lock pin through hole 442.

接著，對替換刀刃20進行說明。替換刀刃20包含托盤60和刃體70。包含在替換刀刃20之刃體70從刃體70之右側，被托盤60所固定住，并從刃體70之左側與滑塊50相連接。 Next, the replacement blade 20 will be described. The replacement blade 20 includes a tray 60 and a blade body 70. The blade body 70 included in the replacement blade 20 is fixed from the right side of the blade body 70 by the tray 60 and is connected to the slider 50 from the left side of the blade body 70.

鎖定構件90其主體部分形成為大致呈四方形之平板狀。在鎖定構件90之頂面具有操作旋鈕91，即在前後方向上較長之直線形凸起。該操作旋鈕91在使用者使鎖定構件90向左右方向移動時使用。在鎖定構件90之主體部分之底面，如圖3的放大圖B所示，在四個角之角部，在下方豎立設置有導柱92。各導柱92具備在其下側頂端部，向前後之外方向分別凸出之翻轉凸起921。翻轉凸起921被形成為，從頂端側向鎖定構件90之基端側逐漸變粗。前方側導柱92c之翻轉凸起921之傾斜面形成在前方側，後方側導柱92d之翻轉凸起921之傾斜面形成在後方側。 The main body of the locking member 90 is formed into a substantially rectangular flat plate shape. There is an operating knob 91 on the top surface of the locking member 90, that is, a linear protrusion that is long in the front-rear direction. The operation knob 91 is used when the user moves the lock member 90 in the left-right direction. On the bottom surface of the main body portion of the locking member 90, as shown in the enlarged view B of FIG. 3, at the corners of the four corners, guide posts 92 are erected below. Each guide post 92 is provided with inverted protrusions 921 protruding in the front, rear, and outer directions at the lower end portion thereof. The inverting protrusion 921 is formed to gradually become thicker from the tip side to the base end side of the lock member 90. The inclined surface of the inverting protrusion 921 of the front guide post 92c is formed on the front side, and the inclined surface of the inverting protrusion 921 of the rear guide post 92d is formed on the rear side.

各導柱92向設置在鍃孔部44之安裝孔441分別對應***。此外，翻轉凸起921設置在貫穿安裝孔441之下方端之露出部分上。因此，翻轉凸起921可防止鎖定構件90從尾端蓋40 之安裝孔441脫落。 The guide posts 92 are respectively inserted into the mounting holes 441 provided in the hole portion 44 respectively. In addition, the inverting protrusion 921 is provided on the exposed part of the lower end of the penetration hole 441. Therefore, the overturning protrusion 921 can prevent the locking member 90 from being removed from the end cap 40 The mounting hole 441 falls off.

在鎖定構件90之主體部分之底面中央位置，形成有在下方豎立設置之鎖定銷93。鎖定銷93其頂端向尾端蓋40之左側呈L字形而彎曲。鎖定銷93貫穿設置在鍃孔部44之鎖定銷貫通孔442上。此外，在鎖定構件90之背面側，向前後方向延伸設置之槽部94a、94b分別形成在左右。各槽部94a、94b被分割成夾持鎖定銷93之前側和後側。該左右任意一個槽部94a、94b與尾端蓋40的卡合凸起443相卡合。 At the center of the bottom surface of the main body of the locking member 90, a locking pin 93 is formed upright below. The top end of the locking pin 93 is bent in an L shape toward the left side of the end cap 40. The lock pin 93 is inserted through the lock pin through hole 442 of the hole portion 44. In addition, on the back side of the lock member 90, grooves 94a and 94b extending in the front and rear directions are formed on the left and right, respectively. Each groove portion 94a, 94b is divided into the front side and the rear side of the clamping lock pin 93. Any one of the left and right grooves 94 a and 94 b is engaged with the engaging protrusion 443 of the tail end cover 40.

圖4(a)係圖1的切刀10之鎖定構件90位置上的IV-IV剖面圖，表示的係鎖定解除狀態；圖4(b)表示的係IV-IV剖面圖的鎖定狀態。由於鎖定構件90之導柱92和鎖定銷93被***到分別形成為長孔狀之安裝孔441和鎖定銷貫通孔442內，因此，可將鎖定構件90向切刀10之左右方向移動。將鎖定構件90向圖面上之右側(切刀10之左側)滑動的話，設置在鎖定構件90之底面之L字形鎖定銷93之頂端，就會如圖4(b)所示，貫穿鎖定孔531。在鎖定銷93貫穿鎖定孔531之鎖定狀態下，滑塊50在前後方向之移動便會受到限制。而且，在鎖定狀態下，鎖定構件90被安裝在尾端蓋40上。因此，尾端蓋40之前後移動亦會受到限制。亦就係說，藉由操作鎖定構件90，在限制切刀10之尾端蓋40拆卸的同時，可限制切刀10之使用。 Fig. 4(a) is a sectional view of IV-IV at the position of the locking member 90 of the cutter 10 of Fig. 1, showing the unlocked state; Fig. 4(b) shows the locked state of the sectional view of IV-IV. Since the guide post 92 and the locking pin 93 of the locking member 90 are inserted into the mounting hole 441 and the locking pin through hole 442 formed in the elongated hole shape, respectively, the locking member 90 can be moved in the left-right direction of the cutter 10. If you slide the locking member 90 to the right side of the drawing (the left side of the cutter 10), the top end of the L-shaped locking pin 93 provided on the bottom surface of the locking member 90 will penetrate the locking hole as shown in Figure 4(b) 531. In the locked state where the locking pin 93 penetrates the locking hole 531, the movement of the slider 50 in the front and rear direction is restricted. Moreover, in the locked state, the locking member 90 is installed on the tail end cap 40. Therefore, the front and back movement of the end cap 40 is also restricted. In other words, by operating the locking member 90, while restricting the removal of the tail end cap 40 of the cutter 10, the use of the cutter 10 can be restricted.

此外，鎖定構件90位於切刀10之右側位置時(圖4(a)之鎖定解除狀態)，設置在圖2和圖3所示之鎖定構件90主體部背面之左側槽部94a與卡合凸起443相卡合。此外，鎖定構件90位於切刀10之左側位置時(圖4(b)的鎖定狀態)，設 置在鎖定構件90背面之右側槽部94b與卡合凸起443相卡合。因此，鎖定構件90在鎖定狀態與鎖定解除狀態之任意一種狀態下被固定住。 In addition, when the locking member 90 is located on the right side of the cutter 10 (the unlocked state of FIG. 4(a)), the left groove portion 94a and the engagement projection are provided on the back of the main body of the locking member 90 shown in FIGS. 2 and 3 From 443 phases snap together. In addition, when the locking member 90 is located on the left side of the cutter 10 (the locked state of FIG. 4(b)), set The right groove portion 94b placed on the back of the locking member 90 engages with the engaging protrusion 443. Therefore, the lock member 90 is fixed in either of the locked state and the unlocked state.

接著，對從切刀10之收納狀態到使用狀態之操作進行說明。圖5係圖1的切刀10之V-V剖面圖，(a)表示的係收納狀態；(b)表示的係使用狀態。圖6係圖5的切刀10之VI-VI剖面圖，(a)表示的係收納狀態；(b)表示的係使用狀態。此外，圖7係放大了圖5的切刀10之操作部52周邊之VII-VII剖面圖。 Next, the operation from the stored state of the cutter 10 to the used state will be described. Fig. 5 is a V-V sectional view of the cutter 10 of Fig. 1, (a) shows the storage state; (b) shows the use state. Fig. 6 is a VI-VI sectional view of the cutter 10 of Fig. 5, (a) shows the storage state; (b) shows the use state. In addition, FIG. 7 is an enlarged cross-sectional view VII-VII around the operating portion 52 of the cutter 10 of FIG. 5.

在圖5(a)之收納狀態下，如圖6(a)所示，滑動凸起631被***到固定孔73之前方側。操作凸起632之滑塊50側的頂點和從該頂點向底板61側傾斜的前後的面，隨著滑塊50之位置與按壓部561相接觸。在收納狀態下，操作凸起632，位於按壓部561之前方傾斜部561c之前方。使用者將操作構件80向前方推出後，就會如圖7所示，設置在操作構件80之卡合解除板83之前端傾斜部83c，將前方之卡合凸起584c，向左前方向(圖7之左下方向)推出，籍此來解除與缺口部321之間的卡合。為此，操作部52則能夠向前方移動。此外，後方之卡合凸起584d伴隨著操作部52向前方移動而向左方(圖7的下方)撓曲，與缺口部321之間的卡合便被解除。 In the storage state of FIG. 5(a), as shown in FIG. 6(a), the sliding protrusion 631 is inserted into the front side of the fixing hole 73. The apex of the operation protrusion 632 on the slider 50 side and the front and back surfaces inclined from the apex to the bottom plate 61 side contact the pressing portion 561 with the position of the slider 50. In the stored state, the operating protrusion 632 is located in front of the inclined portion 561c in front of the pressing portion 561. After the user pushes the operating member 80 forward, as shown in FIG. 7, the front end inclined portion 83c of the engagement release plate 83 of the operating member 80 is provided, and the front engagement protrusion 584c is moved to the front left direction (FIG. 7) push out, thereby releasing the engagement with the notch 321. For this reason, the operation part 52 can move forward. In addition, the rear engaging protrusion 584d bends to the left (downward in FIG. 7) as the operation portion 52 moves forward, and the engagement with the notch portion 321 is released.

此外，在圖5(a)中，滑塊50向前方移動時，下卡止凸起562將上卡止凸起661向上方推上，並將卡止部66之中央，向上方進行彈性變形。因此，對於滑塊50之移動需要規定以上的力，為此，可防止刃體70與滑塊50一起不慎移動。 In addition, in FIG. 5(a), when the slider 50 moves forward, the lower locking projection 562 pushes the upper locking projection 661 upward, and the center of the locking portion 66 is elastically deformed upward . Therefore, a predetermined force or more is required for the movement of the slider 50, and for this reason, the blade 70 and the slider 50 can be prevented from moving accidentally.

圖8係從切刀10之圖6(a)的收納狀態過渡為圖6(b)的使用狀態之過程的剖面圖。操作構件80向前方側推出後，滑動凸起631在具有規定間隙量之狀態下***到作為長孔之固定孔73內。因此，刃體70與滑塊50同時按規定之間隙量向前方移動。而且，如圖8所示，操作凸起632跨上前方傾斜部561c，位於按壓部561之平坦部時，滑動板63向托盤60之右側(圖8的上側)撓曲。為此，滑動凸起631從固定孔73脫離，刃體70便可進一步前進移動。將滑塊50進一步向前方移動後，按壓部561向操作凸起632之前方移動，在彈力之作用下，與向滑塊50側移動後之滑動凸起631相抵接。為此，滑動凸起631位於按壓部561之平坦部，向滑動板63之右方撓曲便得到保持。之後，如圖6(b)所示，按壓部561向滑動凸起631之前方移動後，滑動板63之變形在彈力之作用下復原，刃體70從刃體進出孔31向外部露出。 FIG. 8 is a cross-sectional view of the process of transitioning from the storage state of FIG. 6(a) of the cutter 10 to the use state of FIG. 6(b). After the operating member 80 is pushed out to the front side, the sliding protrusion 631 is inserted into the fixed hole 73 as a long hole with a predetermined amount of clearance. Therefore, the blade body 70 and the slider 50 simultaneously move forward by a predetermined amount of clearance. Moreover, as shown in FIG. 8, when the operating protrusion 632 straddles the front inclined portion 561c and is located on the flat portion of the pressing portion 561, the sliding plate 63 is bent to the right side of the tray 60 (upper side in FIG. 8). For this reason, the sliding protrusion 631 is disengaged from the fixing hole 73, and the blade body 70 can further move forward. After the slider 50 is moved further forward, the pressing portion 561 moves to the front of the operating protrusion 632, and under the action of elastic force, it abuts against the sliding protrusion 631 moved to the slider 50 side. For this reason, the sliding protrusion 631 is located at the flat part of the pressing part 561, and is held by bending to the right of the sliding plate 63. After that, as shown in FIG. 6( b ), after the pressing portion 561 moves in front of the sliding protrusion 631, the deformation of the sliding plate 63 is restored under the action of the elastic force, and the blade 70 is exposed to the outside from the blade inlet and outlet hole 31.

向滑塊50前方之送出操作結束，使用者解除操作構件80之操作後，圖7之卡合凸起584c、584d與任意一個缺口部321相卡合。因此，滑塊50之前後移動便受到限制，可固定刃體70之伸出余量。圖5(b)和圖6(b)的切刀10之使用狀態其外觀揭示於圖1(b)之透視圖。 After the sending operation to the front of the slider 50 is completed and the user releases the operation of the operating member 80, the engaging protrusions 584c and 584d of FIG. 7 are engaged with any of the notches 321. Therefore, the front and back movement of the slider 50 is restricted, and the protrusion margin of the blade body 70 can be fixed. The appearance of the cutter 10 in use state of FIGS. 5(b) and 6(b) is shown in the perspective view of FIG. 1(b).

此外，將滑塊50向後方移動時亦與圖7所示之卡合凸起584c、584d向前方移動時同樣地動作。亦即，由使用者將操作構件80向後方推出後，設置在操作構件80之卡合解除板83之後端傾斜部83d將後方之卡合凸起584d向左後方向(圖7之右下方向)推出，籍此來解除與缺口部321之卡合。為此，操作部52便可向後方移動。此外，前方的卡合凸起584c伴隨著向操作 部52的後方移動，向左方(圖7之下方)撓曲，與缺口部321之卡合便被解除。就這樣，卡合解除板83藉由操作構件80之前後操作，可將與卡合凸起584c、584d之缺口部321之卡合向滑塊50之移動方向解除。 In addition, when the slider 50 is moved backward, it operates in the same manner as when the engaging protrusions 584c and 584d shown in FIG. 7 are moved forward. That is, after the operating member 80 is pushed back by the user, the rear end inclined portion 83d of the engagement release plate 83 provided on the operating member 80 turns the rear engagement protrusion 584d to the left and rear direction (the lower right direction in FIG. 7 ) Is pushed out to release the engagement with the notch 321. For this reason, the operation part 52 can be moved backward. In addition, the front engagement protrusion 584c is accompanied by The rear of the part 52 moves and flexes to the left (downward in FIG. 7), and the engagement with the notch part 321 is released. In this way, the engagement release plate 83 can be released from the engagement with the notches 321 of the engagement protrusions 584c and 584d in the moving direction of the slider 50 by operating the operating member 80 back and forth.

以上，對本發明之實施方式進行了說明。但，本發明並不局限於本實施方式，還可加上各種變更來實施。在本實施方式之說明中，對於將刃體70向前方移動之功能和卸下***到刃體70之滑動凸起631之功能，滑塊50係藉由分別具備卡合凸起563和按壓部561的一個構件來實現的，但結構上亦可不設置按壓部561。例如，亦可將滑動凸起631設置為向前後方向傾斜之凸圓弧上之凸起。因此，可藉由將操作構件80以超過規定之力向前方推壓來使滑動凸起631跨上固定孔73之後方邊緣來解除刃體70與托盤60之間的固定。 Above, the embodiment of the present invention has been described. However, the present invention is not limited to this embodiment, and various changes can be added and implemented. In the description of this embodiment, for the function of moving the blade 70 forward and the function of removing the sliding protrusion 631 inserted into the blade 70, the slider 50 is provided with an engaging protrusion 563 and a pressing portion respectively. It is realized by one component of 561, but the pressing part 561 may not be provided in the structure. For example, the sliding protrusion 631 can also be set as a protrusion on a convex arc inclined in the forward and backward directions. Therefore, it is possible to release the fixation between the blade 70 and the tray 60 by pushing the operating member 80 forward with a force exceeding a predetermined force so that the sliding protrusion 631 straddles the rear edge of the fixing hole 73.

此外，替換刀刃20和滑塊50可作為一個組合件來構成。此時，在作為切刀10之消耗品來更換的替換刀刃中，可包含托盤60、刃體70和滑塊50。因此，更換替換刀刃時，可省去安裝滑塊50之操作，使更換操作變得容易。 In addition, the replacement blade 20 and the slider 50 can be constructed as a single assembly. At this time, the replacement blade to be replaced as a consumable of the cutter 10 may include the tray 60, the blade body 70, and the slider 50. Therefore, when replacing the replacement blade, the operation of installing the slider 50 can be omitted, making the replacement operation easier.

此外，至於滑塊50和刃體70，可在刃體70上設置兩個以上的圓孔和方孔等孔部，籍此來進行固定。或者，亦可在刃體70上設置一個或多個缺口部，可使滑塊50與其缺口部相卡合，從而固定滑塊50和刃體70。 In addition, as for the slider 50 and the blade body 70, two or more holes such as round holes and square holes may be provided on the blade body 70 for fixing. Alternatively, one or more notches may be provided on the blade body 70 so that the slider 50 can be engaged with the notches, so as to fix the slider 50 and the blade body 70.

此外，作為解除固定孔73和滑動凸起631之卡合之方法，並不局限於藉由滑塊50之前進移動來使按壓部561撓曲滑動板63之方法。例如，可使與操作構件80之操作聯動之其他 構件，從滑動板63之左側來抵接，從而撓曲滑動板63。或者，於主體盒30之外側面上設置與滑塊50獨立之解除構件，可藉由該解除構件之按下操作或與滑動操作聯動的構件等來按壓操作凸起632等，從而撓曲滑動板63。 In addition, the method of releasing the engagement between the fixing hole 73 and the sliding protrusion 631 is not limited to the method of causing the pressing portion 561 to bend the sliding plate 63 by moving the slider 50 forward. For example, it can be linked to the operation of the operating member 80. The member abuts from the left side of the sliding plate 63 to bend the sliding plate 63. Alternatively, a release member independent of the slider 50 is provided on the outer side of the main box 30, and the operating protrusion 632 can be pressed by the pressing operation of the release member or a member linked to the sliding operation, etc., to bend and slide板63.

此外，固定孔73並不局限於本實施方式中所示之長孔，例如，亦可采用一個或多個圓孔和方孔。 In addition, the fixing hole 73 is not limited to the long hole shown in this embodiment. For example, one or more round holes and square holes may also be used.

此外，對於滑動凸起631之拆裝方法，亦可由其他方法來構成。例如，主體盒30可具備鎖定構件用以藉由滑動操作和按下操作來切換與刃體70之間之滑動凸起631之固定狀態和固定解除狀態。此外，亦可采用滑動凸起631貫穿固定孔73時，使用螺旋彈簧等來賦能這樣的結構。 In addition, the method of disassembling and assembling the sliding protrusion 631 can also be constructed by other methods. For example, the main box 30 may be provided with a locking member for switching between the fixed state and the fixed release state of the sliding protrusion 631 between the blade body 70 and the blade body 70 by sliding operation and pressing operation. In addition, when the sliding protrusion 631 penetrates the fixing hole 73, a coil spring or the like may be used to energize the structure.

此外，在刃體70上所形成之刃尖71亦可為單刃。 In addition, the blade tip 71 formed on the blade body 70 may also be a single blade.
