[0009] 1. Pliers device Figure 1 is a schematic perspective view showing the entire pliers device 10 of this embodiment. Figure 1 is also a schematic perspective view showing the pliers device 10 with the first gripping portion 104 and the second gripping portion 204 in the open position.

[0010] The pliers device 10 is a tool having a crimping function and a cutting function. The pliers device 10 comprises a first clamping piece 100, a second clamping piece 200, and a shaft portion 18, etc. Each of the first clamping piece 100 and the second clamping piece 200 is a base portion that extends in substantially one direction. The first clamping piece 100 and the second clamping piece 200 are connected so that their extending directions intersect with each other and they can rotate relative to each other.

[0011] Specifically, a through hole 12 is formed in the first clamping piece 100 at an intermediate position, and the second clamping piece 200 is inserted through this through hole 12, thereby giving the pliers device 10 an X shape. Furthermore, the shaft portion 18 is inserted through the through hole 14 of the first clamping piece 100 (see Figure 2) and the through hole 16 of the second clamping piece 200 (see Figure 2), so that the first clamping piece 100 and the second clamping piece 200 are rotatably supported on the shaft portion 18 in a state where they intersect with each other.

[0012] In other words, the pivot axis A of the first clamping piece 100 and the second clamping piece 200 is the central axis of the shaft portion 18, and the pivot axis direction D1 of the first clamping piece 100 and the second clamping piece 200 is the axial direction of the shaft portion 18.

[0013] The first clamping piece 100 has a first clamping portion 104 on one side for holding an article, and a first operation receiving portion 102 on the other side for receiving operations from the user. Similarly, the second clamping piece 200 has a second clamping portion 204 on one side for holding an article, and a second operation receiving portion 202 on the other side for receiving operations from the user.

[0014] The first operation receiving portion 102 and the second operation receiving portion 202 are provided in the same rotation direction and form a pair. Also, the first operation receiving portion 102 and the second operation receiving portion 202 face each other. Further, the first clamping portion 104 and the second clamping portion 204 are provided in the same rotation direction and form a pair. Furthermore, the first clamping portion 104 and the second clamping portion 204 face each other. Note that the rotation direction in each component of the plier device 10 means the direction around the rotation axis A.

[0015] When the first operation receiving portion 102 and the second operation receiving portion 202 approach (close) along the rotation direction, the first clamping portion 104 and the second clamping portion 204 approach due to the principle of the first-class lever. On the other hand, when the first operation receiving portion 102 and the second operation receiving portion 202 separate (open) along the rotation direction, the first clamping portion 104 and the second clamping portion 204 separate due to the principle of the first-class lever.

[0016] Regarding the specific configurations of the first clamping portion 104 and the second clamping portion 204, mainly, reference will be made to FIGS. 2 to 6 for description. FIGS. 2 to 4 are exploded perspective views showing the configurations of the first clamping portion 104 and the second clamping portion 204 of the present embodiment. Further, FIG. 2 is an exploded perspective view seen from the tip side of the first arrangement portion 110, the guide portion 140 side, and the opening direction side of the second clamping portion 204, FIG. 3 is an exploded perspective view seen from the tip side of the first arrangement portion 110, the housing portion 160 side, and the opening direction side of the second clamping portion 204, and FIG. 4 is an exploded perspective view seen from the side opposite to the tip side of the first arrangement portion 110, the outside of the housing portion 160, and the opening direction side of the second clamping portion 204. FIG. 5 is a schematic view showing the configuration of the guide portion 140 of the present embodiment. Also, FIG. 5 is a schematic view seen from the opening end 146a, 146b sides outside the guide portion 140. Note that in FIG. 5, the illustration of the configurations other than the guide portion 140 is omitted. FIG. 6 is a schematic perspective view showing the configurations of the adherend 300 and the tag 306 of the present embodiment.

[0017] The first clamping portion 104 includes a first placement portion 110, a second placement portion 120, a holding portion 130, a guide portion 140, a housing portion 160, etc., and the second clamping portion 204 includes a pressing portion 210, a concave portion 220, a cutting portion 230, a bounce prevention plate 240, etc.

[0018] The first placement portion 110 places the adherend 300 (see FIG. 6) in a state where the extending direction is aligned with the rotation axis direction D1. The adherend 300 extends in one direction and is a cylindrical sleeve capable of bundling two linear bodies 308a and 308b. Two semi-circular through holes 302a and 302b are formed in the adherend 300, and the linear bodies 308a and 308b are appropriately inserted into the through holes 302a and 302b. The linear bodies 308a and 308b may be on one side of different linear members or on both sides of the same linear member. Examples of the linear member include a wire and a core wire of an electric wire. From these, specifically, the first placement portion 110 places the adherend 300 having open ends 304a and 304b at each end in the rotation axis direction D1.

[0019] The first placement portion 110 includes a first support surface 112. The first support surface 112 is an end surface on the closing direction side of the first clamping portion 104 in the first placement portion 110 and supports the adherend 300. Also, in the extending direction D2 of the first clamping portion 104, the middle portion of the first support surface 112 is recessed and curved toward the opening direction side compared to both end edges. Therefore, the first support surface 112 positions and supports at least a part of the adherend 300.

[0020] Further, the first placement portion 110 is divided into two placement pieces 110a and 110b, and the placement pieces 110a and 110b are arranged in a bifurcated shape with a gap in the rotation axis direction D1. The placement pieces 110a and 110b are arranged on both sides of the adherend 300, and the first support surfaces 112 of the placement pieces 110a and 110b support the outer peripheral surfaces on both sides of the adherend 300.

[0021] The second placement section 120 is where the tag 306 (see Figure 6) is placed. The tag 306 is a roughly rectangular plate-shaped member that is integrally formed with the object to be attached 300. The tag 306 is provided on the outside of the object to be attached 300 in the direction of the object's thickness and extends in one direction together with the object to be attached 300.

[0022] The second mounting portion 120 is located outside the first mounting portion 110 and adjacent to the first mounting portion 110 in the extending direction D2 of the first clamping portion 104. Specifically, the second mounting portion 120 is located outside the first mounting portion 110 and on the pivot axis A side in the extending direction D2 of the first clamping portion 104 and adjacent to the first mounting portion 110.

[0023] The second placement section 120 includes a second support surface 122. The second support surface 122 is the closing end face of the first clamping section 104 in the second placement section 120. The second support surface 122 is a substantially rectangular plane and supports the tag 306.

[0024] The second support surface 122 of the second placement section 120 is adjacent to the first support surface 112 of the first placement section 110 in the extending direction D2 of the first clamping section 104, and the edge of the first support surface 112 of the first placement section 110 and the edge of the second support surface 122 of the second placement section 120 are shared, thus forming a continuous structure.

[0025] The retaining portion 130 is provided on the edge of the second support surface 122 of the second placement portion 120 and is a wall that extends toward the closing direction side of the first clamping portion 104. Specifically, the retaining portion 130 is provided in a substantially L-shape in plan view on the edge of the second support surface 122 of the second placement portion 120 that forms the corner opposite to the first placement portion 110 side.

[0026] The pressurizing section 210 works in cooperation with the first placement section 110 to pressurize the object to be adhered 300. Furthermore, the pressurizing section 210 is positioned in the same rotational direction as the first placement section 110. In addition, the pressurizing section 210 faces the first placement section 110.

[0027] The pressurizing portion 210 is provided with a protrusion 212. The protrusion 212 extends in the extending direction D3 of the second clamping portion 204 and protrudes toward the closing direction side of the second clamping portion 204. In addition, the protrusion 212 is located between the arrangement pieces 110a and 110b in the rotation axis direction D1. The amount of protrusion of the protrusion 212 is set to be about half the thickness of the object to be attached 300.

[0028] Furthermore, of the end faces on the closing direction side of the second clamping portion 204 in the pressurizing portion 210, at least the end face of the convex portion 212 is the pressurizing surface 214 that comes into contact with the object to be adhered 300.

[0029] The recess 220 is recessed toward the opening direction of the second clamping portion 204. The recess 220 is formed on the outside of the pressurizing portion 210 and adjacent to the pressurizing portion 210 in the extending direction D3 of the second clamping portion 204. Specifically, the recess 220 is provided on the outside of the pressurizing portion 210 and on the pivot axis A side in the extending direction D3 of the second clamping portion 204 and adjacent to the pressurizing portion 210. Furthermore, the recess 220 is formed in the same rotation direction as the second placement portion 120. Moreover, the recess 220 faces the second placement portion 120.

[0030] The guide portion 140 guides the insertion of the tips of the linear bodies 308a and 308b into the open ends 304a and 304b of the object to be attached 300. The guide portion 140 is located outside the first placement portion 110 and is adjacent to the first placement portion 110 in the rotation axis direction D1.

[0031] The guide portion 140 has a wall that widens as it moves away from the first placement portion 110 along the rotation axis direction D1, and has a space that is roughly pyramidal in shape. Two guide holes 142a and 142b are formed in the guide portion 140. The guide holes 142a and 142b are through holes that extend in the rotation axis direction D1.

[0032] The guide holes 142a and 142b are aligned in the extending direction D2 of the first clamping portion 104, with guide hole 142a located closer to the pivot axis A than guide hole 142b. Furthermore, the two guide holes 142a and 142b communicate in the extending direction D2 of the first clamping portion 104.

[0033] Furthermore, the guide holes 142a and 142b widen as they move away from the first placement portion 110 along the rotation axis direction D1. Specifically, the guide hole 142a widens both on the rotation axis A side and the closing direction side of the first clamping portion 104 in the extending direction D2 of the first clamping portion 104 as it moves away from the first placement portion 110 along the rotation axis direction D1. On the other hand, the guide hole 142b widens both on the opposite side of the rotation axis A side and the closing direction side of the first clamping portion 104 in the extending direction D2 of the first clamping portion 104 as it moves away from the first placement portion 110 along the rotation axis direction D1.

[0034] Based on these findings, the opening ends 144a and 144b on the first arrangement section 110 side have a smaller opening width than the opening ends 146a and 146b on the opposite side.

[0035] Furthermore, the position of the guide hole 142a is slightly shifted from the position of the guide hole 142b towards the opening direction of the first clamping portion 104. Also, the guide hole 142a is enlarged towards the closing direction of the first clamping portion 104 by the amount of the shift from the guide hole 142b. As a result, the positions of the opening end 144a and the opening end 146a are also slightly shifted towards the opening direction of the first clamping portion 104 and enlarged towards the closing direction of the first clamping portion 104 by the amount of the shift.

[0036] Furthermore, on the inner surface of the guide portion 140 on the opening side of the first clamping portion 104, a guide wall 148 is provided between the guide holes 142a and 142b. The guide wall 148 extends in the rotation axis direction D1 and slightly extends toward the closing side of the first clamping portion 104. Specifically, the guide wall 148 extends toward the closing side of the first clamping portion 104 to the extent that the opening ends 144a and 144b are separated.

[0037] The open end 144a of the guide portion 140 is located at the same position as the first support surface 112 of the first placement portion 110 in the extending direction D2 of the first clamping portion 104, and is separated from the first support surface 112 in the closing direction of the first clamping portion 104. Specifically, the open end 144a of the guide portion 140 is separated from the first support surface 112 of the first placement portion 110 to the extent that, when the object to be attached 300 is placed in the first placement portion 110 (see Figure 7), it is located on the same rotation axis direction D1 as the open end 304a of the object to be attached 300.

[0038] Furthermore, the size of the open end 144a of the guide portion 140 is smaller than the open end 304a of the object to be attached 300 when the object to be attached 300 is placed in the first placement portion 110 (see Figure 7).

[0039] The open end 144b of the guide portion 140 is located at the same position as the first support surface 112 of the first placement portion 110 in the extending direction D2 of the first clamping portion 104, and is separated from the first support surface 112 in the closing direction of the first clamping portion 104. Specifically, the open end 144b of the guide portion 140 is separated from the first support surface 112 of the first placement portion 110 to the extent that, when the object to be attached 300 is placed in the first placement portion 110 (see Figure 7), it is located on the same rotation axis direction D1 as the open end 304b of the object to be attached 300.

[0040] Furthermore, the size of the open end 144b of the guide portion 140 is smaller than the open end 304b of the object to be attached 300 when the object to be attached 300 is placed in the first placement portion 110 (see Figure 7).

[0041] Based on these findings, the sizes of the open ends 146a and 146b of the guide section 140 are larger than the open ends 144a and 144b on the first placement section 110 side, and the open ends 304a and 304b of the adherend 300.

[0042] Furthermore, the guide portion 140 has a notch 150 that opens to the closing side of the first clamping portion 104, which is wider than the guide wall 148. In the extending direction D2 of the first clamping portion 104, the width of the notch 150 is greater than or equal to the sum of the thicknesses of the linear bodies 308a and 308b. Also, the notch 150 widens in the extending direction D2 of the first clamping portion 104 as it moves away from the first placement portion 110 along the rotation axis direction D1.

[0043] The cutting section 230 cuts the linear bodies 308a and 308b. The cutting section 230 is located outside the first placement section 110 and on the opposite side of the guide section 140 in the rotation axis direction D1, and is adjacent to the pressurizing section 210.

[0044] The cutting section 230 includes a blade portion 232. The blade portion 232 extends in the extending direction D3 of the second clamping section 204 and protrudes toward the closing direction side of the second clamping section 204. In the rotational direction, the tip of the blade portion 232 is located at the same position as the tip of the convex portion 212 of the pressurizing section 210, or slightly toward the opening direction side of the second clamping section 204 than the tip position of the convex portion 212 of the pressurizing section 210. In this embodiment, the blade portion 232 is a single-edged blade with the tip of the blade facing the first arrangement section 110, but the blade portion 232 may be double-edged.

[0045] The bounce-prevention plate 240 prevents the cut pieces 310a and 310b (see Figure 11) of the linear bodies 308a and 308b from bouncing when the linear bodies 308a and 308b are cut. The bounce-prevention plate 240 is located outside the cutting section 230 and on the opposite side of the pressurizing section 210 in the rotation axis direction D1, and is adjacent to the cutting section 230.

[0046] The bounce-prevention plate 240 is a plate that intersects the rotation direction and extends in the rotation axis direction D1. The bounce-prevention plate 240 is located on the opening direction side of the second clamping portion 204, beyond the tip of the blade portion 232 of the cutting portion 230. The distance between the bounce-prevention plate 240 and the tip of the blade portion 232 is set to be greater than or equal to the thickness of the linear body 308a or the linear body 308b.

[0047] The housing section 160 houses the cut pieces 310a and 310b (see Figure 11) of the linear bodies 308a and 308b. The housing section 160 is located outside the first placement section 110 and on the opposite side from the guide section 140 in the rotation axis direction D1, and is adjacent to both the first placement section 110 and the second placement section 120. Furthermore, the housing section 160 is located in the same rotation direction as the cutting section 230 and the bounce prevention plate 240. In addition, the housing section 160 faces both the cutting section 230 and the bounce prevention plate 240.

[0048] The housing section 160 is box-shaped, with the closing side of the first clamping section 104 communicating with the interior, and its bottom surface 162 positioned on the opening side of the first clamping section 104 relative to the first support surface 112 of the first placement section 110. Although the wall of the housing section 160 on the side of the first placement section 110 is omitted, the first placement section 110 and the second placement section 120 are used as walls of the housing section 160 by being adjacent to both of them.

[0049] The open end 164 of the housing section 160 is located in the same position as the second support surface 122 of the second arrangement section 120 in the rotational direction. Furthermore, the opening size and shape of the housing section 160 are the same regardless of its position in the depth direction.

[0050] The opening size of the housing section 160 is larger than the size of the frame formed by joining the outer edges of the cutting section 230 blade 232 and the anti-slip plate 240 when the second clamping section 204 is viewed from the closing side of the second clamping section 204, and the shape of the opening of the housing section 160 is the same as that of the frame.

[0051] Of the inner surfaces of the housing portion 160, each of the surfaces 166 intersecting the extending direction D2 of the first clamping portion 104 is located at the same position as the edge of the first support surface 112 of the first placement portion 110, or outside the first support surface 112, in the extending direction D2 of the first clamping portion 104.

[0052] Furthermore, the inner surface of the housing 160 includes a pair of anti-warping surfaces 168a and 168b that face each other in the rotation axis direction D1. The distance between the anti-warping surfaces 168a and 168b is greater than or equal to the width of the blade portion 232 of the cutting section 230 in the rotation axis direction D1. In addition, each of the anti-warping surfaces 168a and 168b is located at the same position as the end face of the blade portion 232, or slightly outside the blade portion 232, in the rotation axis direction D1.

[0053] 2. Usage example Next, examples of the use of the pliers device 10 will be described, mainly with reference to Figures 7 to 11. Figures 7 to 10 are schematic perspective views illustrating examples of the use of the pliers device 10 of this embodiment. Figures 7-8 and 10 are schematic perspective views from the tip side of the first placement section 110, the housing section 160 side, and the opening direction side of the second clamping section 204. Figure 9 is an exploded perspective view from the opposite side of the tip side of the first placement section 110, the outside of the guide section 140, and the opening direction side of the second clamping section 204. Figure 11 is a schematic diagram illustrating examples of the use of the pliers device 10 of this embodiment. Figure 11 is also a schematic diagram of the outside of the first placement section 110 in the extending direction D2 of the first clamping section 104, from the side opposite to the second placement section 120 side. Figures 3 to 6 may also be referred to when describing examples of the use of the pliers device 10.

[0054] First, the user separates the first operation receiving section 102 and the second operation receiving section 202, thereby separating the first clamping section 104 and the second clamping section 204, and then places the object to be attached 300 and the tag 306 on the first placement section 110 and the second placement section 120, as shown in Figure 7. Specifically, both sides of the object to be attached 300 are placed on the placement pieces 110a and 110b.

[0055] When the object to be attached 300 and the tag 306 are placed in the first placement section 110 and the second placement section 120, the open end 304a of the object to be attached 300 on the guide section 140 side is located on the same rotation axis direction D1 as the open end 144a of the guide section 140 (see Figure 3, etc.), and the open end 304b of the object to be attached 300 on the guide section 140 side is located on the same rotation axis direction D1 as the open end 144b of the guide section 140 (see Figure 3, etc.). Furthermore, when the object to be attached 300 and the tag 306 are placed in the first placement section 110 and the second placement section 120, the object to be attached 300 faces the pressurizing section 210, and the tag 306 faces the recess 220.

[0056] Furthermore, the first support surface 112 (see Figure 3, etc.) of the first placement portion 110 prevents the first clamping portion 104 from shifting in the extending direction D2 of the attached object 300, and the holding portion 130 prevents the first clamping portion 104 from shifting in the direction of rotation axis D1, as well as in the direction of extension D2 of the tag 306 that is opposite to the first placement portion 110. Since the attached object 300 and the tag 306 are integrally constructed, both the displacement in the direction of rotation axis D1 and the displacement of the first clamping portion 104 in the extending direction D2 are prevented for the attached object 300 and the tag 306 as a whole.

[0057] Next, as shown in Figure 8, the user inserts the ends of the linear member 312, which has been pre-inserted through the through hole 316 of the object to be attached 314, that is, the ends of the linear bodies 308a and 308b, into the open ends 146a and 146b of the guide portion 140. The object to be attached 314 is, for example, a fastening bolt for the lid of a 18-liter can.

[0058] Furthermore, after inserting the tips of the linear bodies 308a and 308b into the open ends 146a and 146b of the guide section 140, the user moves the tips of the linear bodies 308a and 308b toward the object to be attached 300, thereby passing the tips of the linear bodies 308a and 308b through the open ends 144a and 144b of the guide section 140 (see Figure 3). In other words, the user passes the linear bodies 308a and 308b through the guide holes 142a and 142b of the guide section 140.

[0059] When the tips of the linear bodies 308a and 308b move toward the object to be attached 300 while contacting at least one of the inner surface of the guide portion 140 and the guide wall 148 within the guide holes 142a and 142b of the guide portion 140, the tips of the linear bodies 308a and 308b are guided toward the open ends 144a and 144b of the guide portion 140. Furthermore, when the tips of the linear bodies 308a and 308b move toward the object to be attached 300 while contacting the guide wall 148 within the guide holes 142a and 142b of the guide portion 140, the direction of movement of the tips of the linear bodies 308a and 308b is set to the rotation axis direction D1.

[0060] Furthermore, the open ends 144a and 144b of the guide section 140 are separated by the guide wall 148. Therefore, when the linear bodies 308a and 308b pass through the open ends 144a and 144 of the guide section 140 with their direction of travel inclined with respect to the rotation axis direction D1, they come into contact with the guide wall 148. Consequently, after passing through the open ends 144a and 144b of the guide section 140, the tips of the linear bodies 308a and 308b are located on the same rotation axis direction D1 as the open ends 144a and 144b of the guide section 140.

[0061] Next, as shown in Figure 9, the user moves the tips of the linear bodies 308a and 308b further toward the object to be attached 300, and inserts the tips of the linear bodies 308a and 308b into the open ends 304a and 304b on the guide portion 140 side of the object to be attached 300. After that, the user moves the tips of the linear bodies 308a and 308b toward the housing portion 160, passing the tips of the linear bodies 308a and 308b through the open ends 304a and 304b on the housing portion 160 side of the object to be attached 300. In other words, the user passes the linear bodies 308a and 308b through the through holes 302a and 302b of the object to be attached 300.

[0062] When the linear bodies 308a and 308b are inserted through the through holes 302a and 302b of the object to be attached 300, the portions of the linear bodies 308a and 308b closer to the housing portion 160 than the first placement portion 110 face the bottom surface 162 of the housing portion 160, the cut portion 230, and the anti-bouncing plate 240, respectively.

[0063] Next, the user determines the attachment positions of the object to be attached 300 and the tag 306 to the linear bodies 308a and 308b by moving one or more of the pliers device 10, the object to be attached 314, and the linear member 312 in the rotation axis direction D1.

[0064] Next, as shown in Figure 10, the user brings the first operation receiving section 102 and the second operation receiving section 202 closer together, thereby bringing the first clamping section 104 and the second clamping section 204 closer together, and the first placement section 110 and the pressurizing section 210 clamp the object to be attached 300 with a force that does not deform the object to be attached 300.

[0065] At this time, both the blade portion 232 of the cutting portion 230 and the anti-bounce plate 240 face the bottom surface 162 of the housing portion 160, while covering the portion of the linear bodies 308a and 308b that is closer to the housing portion 160 than the first placement portion 110, near the open end 164 of the housing portion 160. Also, at this time, the anti-bounce plate 240 covers the linear bodies 308a and 308b without coming into contact with them.

[0066] Next, as shown in Figure 11, the user brings the first operation receiving section 102 and the second operation receiving section 202 closer together to perform both crimping and cutting. When crimping is performed, the first placement section 110 and the pressurizing section 210 work together to crimp (crimp) the adherend 300 that bundles the linear bodies 308a and 308. Specifically, when crimping is performed, a compressive stress in the rotational direction is applied to the adherend 300 through the cooperation of the convex section 212 and the placement pieces 110a and 110b, and the adherend 300 is crimped and fixed together with the linear bodies 308a and 308. Furthermore, when cutting is performed, the linear bodies 308a and 308b sandwiched between the blade portion 232 of the cutting portion 230 and the second support surface 122 of the placement piece 110b are cut by shear stress, and the unnecessary portions of the linear bodies 308a and 308b are removed. The unnecessary portions of the linear bodies 308a and 308b refer to the portions of the linear bodies 308a and 308b that are closer to the housing portion 160 than to the first placement portion 110 in the rotation axis direction D1.

[0067] The cut pieces 310a and 310b of the linear bodies 308a and 308 are stored in the storage section 160. Furthermore, even if the cut pieces 310a and 310b bounce when the linear bodies 308a and 308 are cut, they will collide with the bounce prevention plate 240, fall into the storage section 160, and as a result be stored and recovered within the storage section 160.

[0068] Furthermore, when cutting the linear bodies 308a and 308, the pair of anti-warping surfaces 168a and 168b prevent the blade portion 232 of the cutting portion 230 from warping (loosening) in the rotation axis direction D1. In addition, when cutting the linear bodies 308a and 308, the recess 220 prevents pressure from being applied to the tag 306.

[0069] Next, the user separates the first operation receiving section 102 and the second operation receiving section 202, thereby separating the first clamping section 104 and the second clamping section 204, and moves the object to be attached 300 and the tag 306, etc., towards the closing direction of the first clamping section 104, thereby removing the object to be attached 300 and the tag 306, etc., from the pliers device 10. When removing the object to be attached 300 and the tag 306, etc., from the pliers device 10, the linear bodies 308a and 308b, which are inserted through the guide holes 142a and 142b of the guide section 140, are removed from the guide section 140 through the notch 150.

[0070] When the pliers device 10 is used in this manner, the tag 306 is suspended from the object 314 by the linear member 312.

[0071] With the guide portion 140 of the pliers device 10 in this embodiment, after inserting the tips of the linear bodies 308a and 308b into the open ends 146a and 146 of the guide portion 140, the tips of the linear bodies 308a and 308b can be inserted into the open ends 304a and 304b of the workpiece 300 on the guide portion 140 side simply by moving the tips of the linear bodies 308a and 308b toward the workpiece 300 located in the first placement portion 110. Therefore, with the guide portion 140 of the pliers device 10 in this embodiment, insertion of the linear bodies 308a and 308b into the open ends 304a and 304b of the workpiece 300 can be easily performed.

[0072] Furthermore, in the pliers device 10 of this embodiment, the first placement section 110 and the pressurizing section 210 can crimp the workpiece 300 that bundles the linear bodies 308a and 308b, while the cutting section 230 can remove the unnecessary parts of the linear bodies 308a and 308b. In other words, the pliers device 10 of this embodiment can perform two processes, crimping and cutting, simultaneously. Therefore, the pliers device 10 of this embodiment improves work efficiency compared to when crimping and cutting are performed separately.

[0073] Furthermore, the storage section 160 of the pliers device 10 of this embodiment allows the cut pieces 310a and 310b of the linear bodies 308a and 308b to be stored in the storage section 160. Therefore, the storage section 160 of the pliers device 10 of this embodiment can prevent the cut pieces 310a and 310b of the linear bodies 308a and 308b from scattering on the floor of the work site, and as a result, the effort required to clean the work site can be reduced.

[0074] Furthermore, the pair of anti-warping surfaces 168a and 168b of the pliers device 10 of this embodiment can prevent the blade portion 232 of the cutting portion 230 from warping (loosening) in the rotation axis direction D1 when cutting the linear bodies 308a and 308b. Therefore, the pair of anti-warping surfaces 168a and 168b of the pliers device 10 of this embodiment can also prevent the cut surface from becoming slanted when cutting the linear bodies 308a and 308b. In other words, the pair of anti-warping surfaces 168a and 168b of the pliers device 10 of this embodiment can also prevent the tips of the linear bodies 308a and 308b from becoming sharp after cutting. As a result, the pair of anti-warping surfaces 168a and 168b of the pliers device 10 of this embodiment can also prevent the sharp tips of the linear bodies 308a and 308b from adversely affecting objects or people.

[0075] Furthermore, with the bounce-prevention plate 240 of the pliers device 10 of this embodiment, even if the cut pieces 310a and 310b of the linear bodies 308a and 308 bounce, the cut pieces 310a and 310b can be contained within the storage section 160. In other words, with the bounce-prevention plate 240 of the pliers device 10 of this embodiment, the cut pieces 310a and 310b of the linear bodies 308a and 308 can be reliably contained within the storage section 160.

[0076] Furthermore, the guide holes 142a and 142b of the guide portion 140 of the pliers device 10 in this embodiment are widened as they move away from the first placement portion 110 along the rotation axis direction D1. Therefore, in the guide portion 140 of the pliers device 10 in this embodiment, the size of the open ends 146a and 146b on the side of the guide portion 140 opposite to the first placement portion 110 is large, making it easy to insert the linear bodies 308a and 308b into the open ends 146a and 146b of the guide portion 140.

[0077] Furthermore, according to the second placement section 120 of the pliers device 10 of this embodiment, a tag 306 integrated with the object to be attached 300 can be placed.

[0078] Furthermore, the holding portion 130 of the pliers device 10 of this embodiment prevents not only misalignment of the tag 306 in the rotational axis direction D1, but also misalignment of the first gripping portion 104 of the tag 306 in the extension direction D2 toward the side opposite to the first placement portion 110.

[0079] Furthermore, the recess 220 of the pliers device 10 in this embodiment makes it possible to avoid pressurizing the tag 306 when crimping the adherend 300 that bundles the linear bodies 308a and 308b.

[0080] Furthermore, the first support surface 112 of the first placement section 110 of the pliers device 10 of this embodiment prevents misalignment of the object to be attached 300 in the extending direction D2 of the first clamping section 104.

[0081] 3. Variant This concludes the description of embodiments of the present invention. However, the specific configurations shown in these embodiments are merely examples, and the embodiments of the present invention are not limited to those shown in these embodiments.

[0082] The first operation receiving section 102 may be provided on the first placement section 110 side of the first clamping section 104, and the second operation receiving section 202 may be provided on the pressurizing section 210 side of the second clamping section 204. In this case, the pliers device 10 is V-shaped. Also in this case, as the first operation receiving section 102 and the second operation receiving section 202 move closer together along the rotational direction, the first clamping section 104 and the second clamping section 204 move closer together due to the principle of a second-class lever. On the other hand, as the first operation receiving section 102 and the second operation receiving section 202 move away from each other along the rotational direction, the first clamping section 104 and the second clamping section 204 move away from each other due to the principle of a second-class lever.

[0083] Furthermore, the pliers device 10 may include an elastic member that biases the first gripping portion 104 and the second gripping portion 204 in a direction that separates them. An example of an elastic member is a compression spring. The elastic member may also be positioned between the first operating receiving portion 102 and the second operating receiving portion 202 and connected to both of them. Alternatively, the elastic member may be positioned between the first gripping portion 104 and the second gripping portion 204 and connected to both of them. With an elastic member, the effort required to separate the first gripping portion 104 and the second gripping portion 204 from each other can be eliminated.

[0084] The pliers device 10 may include a limiting mechanism that prevents excessive pressure on the workpiece 300 by interfering with the approach of the first clamping portion 104 and the second clamping portion 204. The limiting mechanism includes a first interference portion and a second interference portion, the first interference portion being provided on the first clamping portion 104 and the second interference portion being provided on the second clamping portion 204. The first interference portion and the second interference portion are located in the same rotational direction. Immediately after the crimping of the workpiece 300 bundling the linear bodies 308a and 308b and the cutting of the linear bodies 308a and 308 are completed, the first interference portion and the second interference portion come into contact with each other in the rotational direction when the first clamping portion 104 and the second clamping portion 204 approach each other, interfering with any further approach between the first clamping portion 104 and the second clamping portion 204. For example, if the first interfering portion is the blade portion 232 of the cutting portion 230, the second interfering member may be a protrusion that projects from the anti-warping surface 168a in the rotation axis direction D1. In this case, the protrusion is located slightly on the opening direction side of the first clamping portion 104 than the first support surface 112 of the first placement portion 110, and is on the rotation direction of the blade portion 232.

[0085] Furthermore, the second placement portion 120 may be provided on the outside of the first placement portion 110 and on the opposite side from the pivot axis A in the extending direction D2 of the first clamping portion 104.
