Description

Technical Field

[0001] This utility model relates to a wire gripper, and more particularly to a wire gripper used, for example, to grip a wire during the process of pulling the wire while cutting a covered wire. Background Technology

[0002] When cutting electrical wires, a wire slitting tool is used to loosen the wire at the point where it is pulled and cut. Typically, such a wire slitting tool is configured to connect wire grippers to both ends of a retractable telescopic shaft. By using this wire slitting tool, the wire is gripped at each end while the central telescopic shaft retracts, causing the wire between the two grippers to loosen in an arched shape. One such wire gripper is known (see Patent Document 1).

[0132] The fixed gripper 20 has a second back protrusion that protrudes from the upper part of the back side toward the lower part of the back side and has a generally convex shape on the back side, so that the fixed gripper 20 is more difficult to be damaged by forces (forces from the upper side to the lower side) and / or forces (forces from the lower side to the upper side) received from the first link member 70 from the upper surface side toward the lower surface side.

[0133] The first back protrusion of one side is a protrusion that extends longer from the upper side to the lower side, and the second back protrusion of the other side is a protrusion that extends longer from the upper side to the lower side.

[0134] The first and second rear protrusions are separated by a certain interval and divided into left and right sides.

[0135] The fixed gripper 20 has a protrusion 29 in a generally rectangular shape to prevent the wire-shaped gripper 20 from being damaged by the force applied from the wire-shaped gripper 30 when the wire-shaped gripper 20 is gripped between the wire-shaped pressing part 30 and the rear mounting part 34 and the first connecting rod member 70, and the first wire gripper 10A and the second wire gripper 10B approach each other and the wire-shaped gripper 10B flexes in a direction away from the cylindrical body 510 and the telescopic body 520 of the live wire separating tool 1000.

[0140] The first link component mounting part 52 and the second link component mounting part 54 are the parts that constitute the link mechanism 18. They are separated by a certain interval and are divided into left and right sides.

[0141] In this embodiment, the first link component mounting part 52 is formed on the right side of the movable gripper 50, and the second link component mounting part 54 is formed on the left side of the movable gripper 50.

[0142] The movable gripper 50 has a movable inner hole 62 for inserting the first link member 70 and the second link member 100.

[0143] The first link component mounting portion 52 has a first movable inner hole portion 62A for inserting the first link component 70, and the second link component mounting portion 54 has a second movable inner hole portion 62B for inserting the second link component 100.

[0150] The main body 72 of the linkage component has a movable gripper mounting part 74 forming a region for mounting to the movable gripper 50, a fixed gripper mounting part 76 forming a region for mounting to the fixed gripper 20, and an operation member mounting part 78 forming a region for mounting to the operation member 130 at the lower part of the linear body holding part 60.

[0151] In this embodiment, the movable gripper mounting part 74 is formed on the right side of the movable gripper 50, and the fixed gripper mounting part 76 is formed on the left side of the movable gripper 50.

[0155] (Guiding mechanism of linkage mechanism)

[0156] The first link component 70 also has:

[0157] The guide portion 80 is formed as a roughly semi-circular arc shape protruding from the center of the main body portion 72 of the connecting rod component toward the direction of pulling the operating component 130.

[0158] The guide section 80 is a part that constitutes the interval adjustment mechanism 12, the guide mechanism 14 and the movement restriction mechanism 16. It is a plate-shaped body that is roughly semi-circular when viewed from the front, and is integrally formed with the main body of the connecting rod component 72.

[0159] The guide section 80 is configured to droop downward from the main body section 72 of the linkage component, that is, in the direction away from the movable gripper 50.

[0160] The guide section 80 is provided with a small path section 82 that extends from the side that pushes the operating component 130 back toward the side that pulls the operating component 130, and is roughly semi-circular when viewed from the front.

[0161] The guide section 80 has guide protrusions 84 around the path section 82.

[0163] The guide protrusion 84 has a roughly semi-circular guide edge 86 at its lower edge and an upper edge 88 (guide portion) facing the guide edge 86.

[0164] The path section 82 has a path section end 90 formed on the side of the main body section 72 of the connecting rod component. From the upper side of the path section end 90, the upper edge 92 of the path section extends toward the direction of pulling the operating component 130. In addition, from the lower side of the path section end 90, the lower edge 96 of the path section extends toward the direction of pulling the operating component 130.

[0166] The path portion 82 is separated from the guide edge 86 and the upper edge 88 by an equal distance, and the upper edge portion 92 and the lower edge portion 96 of the path portion are formed to be almost parallel.

[0167] The height difference between the end 90 of the path section and the side edge 94 of the path section corresponds to the vertical movement distance of the movable gripper 50, that is, the distance by which the gap between it and the fixed gripper 20 can be widened or shortened. In other words, the side edge 94 of the path section is positioned above or below the end 90 of the path section, corresponding to the distance the movable gripper 50 moves away from the fixed gripper 20.

[0168] As shown in Figure 4, the guide edge 86 of the guide part 80 is configured such that, by operating the operating member 130, the engaging guide part 364 of the slider 330 moves from the left side of the small path end 90 to the right side, thereby causing the movable gripper 50 to move upward, i.e., the fixed gripper 20.

[0266] like Figure 1 As shown in Figure 2, the second movable pivot hole 68 of the first linkage component mounting portion 52 of the movable gripper 50 is connected to the first pivot hole 98a of the first linkage component 70, so that the inner surface of the first linkage component mounting portion 52 of the movable gripper 50 contacts the surface and back surface of the first linkage component 70, and the pivot 126A is embedded in the second movable pivot hole 68 of the movable gripper 50 and the first pivot hole 98a of the first linkage component 70. Through the pivot 126A, the first linkage component 70 can be rotatably mounted on the movable gripper 50.

[0267] like Figure 1 As shown in Figure 2, the second connecting pivot hole 158 of the first connecting member 140 is continuous with the third pivot hole 98c of the first connecting rod member 70, so that the back side of the first connecting member 140 faces the front side of the first connecting rod member 70. Furthermore, the fifth connecting pivot hole 188 of the second connecting member 170 is continuous with the third pivot hole 98c of the first connecting rod member 70, so that the front side of the second connecting member 170 faces the back side of the first connecting rod member 70.

[0268] The pivot 120 is inserted into the second connecting pivot hole 158 and the fifth connecting pivot hole 188 of the operating member 130 and the third pivot hole 98c of the first link member 70. Through the pivot 120, the first link member 70 can be rotatably mounted on the operating member 130.

[0269] In addition, a spacer is provided between the first link component 70 and the first connecting component 140 and the second connecting component 170.

[0270] like Figure 1As shown in Figure 2, the first fixed pivot hole 40 of the second link component mounting portion 24 of the fixed gripper 20 is continuous with the second pivot hole 112 of the fixed gripper mounting portion 106 of the second link component 100. The front surface of the front protrusion 36 of the second link component mounting portion 24 of the fixed gripper 20 faces the surface of the fixed gripper mounting portion 106 of the second link component 100. The pivot 124B is inserted into the first fixed pivot hole 40 of the fixed gripper 20 and the second pivot hole 112 of the second link component 100. Through the pivot 124B, the second link component 100 can be rotatably mounted on the fixed gripper 20.

[0271] like Figure 1 As shown in Figure 2, the first movable pivot hole 66 of the movable gripper 50 and the first pivot hole 110 of the second link member 100 are connected, so that the inner surface of the first movable inner hole 62A of the second link member mounting portion 54 of the movable gripper 50 contacts the surface and back surface of the second link member 100, so that the pivot 124A is embedded in the first movable pivot hole 66 of the movable gripper 50 and the first pivot hole 110 of the second link member 100. Through the pivot 124A, the second link member 100 can be rotatably mounted on the movable gripper 50.

[0272] like Figure 1 As shown in Figure 2, the third connecting pivot hole 160 of the first connecting member 140 is continuous with the third pivot hole 114 of the second connecting rod member 100, so that the back side of the first connecting member 140 faces the front side of the second connecting rod member 100. Furthermore,

[0273] The sixth connecting pivot hole 190 of the second connecting member 170 is connected to the third pivot hole 114 of the second connecting rod member 100, so that the front side of the second connecting member 170 faces the back side of the second connecting rod member 100.

[0274] Pivot 122 is inserted into the third connecting pivot hole 160 and the sixth connecting pivot hole 190 of the operating component 130 and the third pivot hole 114 of the second link component 100. Through pivot 122, the second link component 100 can be rotatably mounted on the operating component 130.

[0275] Furthermore, a spacer is provided between the second link component 100 and the first connecting component 140 and the second connecting component 170.

[0276] like Figure 1 And as shown in Figure 2,

[0277] By connecting the mounting hole 348 of the retaining part 340 with the path part 82 of the first connecting rod member 70.

[0278] The vertical wall 360 of the inner groove 342 of the retaining part 340 and the inner surface of the vertical wall 362 face the front side surface of the guide part 80 of the first connecting rod member 70 and the back side surface of the first connecting rod member 70, and the lower end edge 86 of the guide part 80 contacts the engaging guide part 364 of the retaining part 340.

[0279] The stop part 344 is inserted into the mounting hole 348 of the slider 330, so that the slider 330 is mounted on the first connecting rod part 70.

[0280] like Figure 1 As shown in Figure 2, when the ring portion 332 of the slider 330 is rotated, the screw 334 rotates inside the screw mounting hole 316 of the regulating portion body 302, thereby causing the holding portion 340 to move up and down.

[0281] By connecting the fixed gripper 20 and the movable gripper 50 to the first link member 70 and the second link member 100 in this way, the movable gripper 50 can approach and move away from the fixed gripper 20 when the first link member 70 and the second link member 100 are rotated.

[0282] The wire gripper 10 of the first embodiment of this utility model holds the wrapped wire W between the fixed gripper 20 and the movable gripper 50 by positioning the wrapped wire W between the fixed gripper 20 and the movable gripper 50 and rotating the first link member 70 and the second link member 100, thereby bringing the movable gripper 50 close to the fixed gripper 20 and holding the wrapped wire W between the wire pressing part 30 of the fixed gripper 20 and the wire holding part 60 of the movable gripper 50.

[0283] The engaging guide 364 of the retaining part 340 can slidably contact the lower edge 86 of the guide part of the first link member 70. In addition, the height difference between the end of the path part 90 and the side edge of the path part 94 corresponds to the vertical movement distance of the movable gripper 50, that is, the distance that can be opened or closed between the gripper 50 and the fixed gripper 20. That is, the engagement guide 364 of the holding part 340 is formed in a roughly arc shape corresponding to the distance of the movable gripper 50 from the fixed gripper 20, and the side edge 94 of the path part is positioned below the end 90 of the path part. Therefore, when the holding part 340 of the regulating part body 302 moves up and down by rotating the ring part 332 of the slider 330, the engagement guide 364 of the holding part 340 moves up and down along the lower edge 86 of the guide part of the first connecting rod member 70. The first connecting rod member 70 and the second connecting rod member 100, which together with the first connecting rod member 70 constitute a parallel crank mechanism, rotate. As a result, the movable gripper 50, on which the first connecting rod member 70 and the second connecting rod member 100 are rotatably mounted, moves forward and backward relative to the fixed gripper 20.

[0284] As shown in Figures 2 and 4, when the movable gripper 50, on which the first link component 70 and the second link component 100 are rotatably mounted, moves forward or backward relative to the fixed gripper 20, the interval between the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 changes.

[0285] The gap between the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 is widest when the engaging guide part 364 of the slider 330 is close to the left side of the guide part 80 (the end of the path part 90 side of the path part 82), and narrowest when the engaging guide part 364 of the slider 330 is close to the right side of the guide part 80 (the side of the guide part 80 furthest from the main body part 72 of the connecting rod component).

[0286] When a wire W is sandwiched between the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50, and the holding part 340 of the regulating part body 302 moves up and down by rotating the ring part 332 of the slider 330, thereby causing the first link member 70 to rotate and the movable gripper 50 to approach the fixed gripper 20, and the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 press the side of the wire W with a strong force, the engaging guide part 364 of the holding part 340 receives a strong force from the lower edge 86 of the guide part of the first link member 70.

[0287] Therefore, a large frictional force will be generated between the engaging guide 364 of the retaining part 340 and the lower edge 86 of the guide part of the first connecting rod member 70. So if the ring part 332 of the slider 330 is not rotated to reduce the force of the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 pressing the side of the wire W, the engaging guide 364 of the retaining part 340 will not move to the right or left.

[0288] As shown in Figure 2, a guide portion 80 of the first connecting rod member 70 is inserted into the inner groove portion 342 of the holding portion 340 of the slider 330. In addition, a locking guide portion 364 is embedded in the path portion 82 of the first connecting rod member 70 and the mounting hole 348 of the slider 330. Therefore, the guide portion 80 of the first connecting rod member 70 is maintained in a state in which it can always slide in contact with the inner groove portion 342 of the holding portion 340 of the slider 330.

[0289] Regarding the first link component 70, such as Figure 1 As shown,

[0290] The surface and back of the movable gripper mounting portion 74 of the first link member 70 are in contact with the inner surface of the second movable inner hole portion 62B of the movable gripper 50, and the surface and back of the guide portion 80 are in contact with the inner groove portion 342 of the regulating portion 300. Therefore, the first link member 70 is prevented from deforming to the front or back side by the second movable inner hole portion 62B of the movable gripper 50 and the inner groove portion 342 of the slider 330.

[0291] Therefore, by preventing the first link member 70 from deforming to the front or back side, the wire gripper 10 can prevent the force of gripping the wrapped wire W from decreasing or gaps from forming between the wrapped wire W and the fixed gripper 20, after the movable gripper 50 approaches the fixed gripper 20 and grips the wrapped wire W between the wire pressing part 30 of the fixed gripper 20 and the wire holding part 60 of the movable gripper 50.

[0292] (Linkage mechanism)

[0293] like Figure 1 As shown in Figure 2, the movable gripping body 50, the first connecting rod component 70, the second connecting rod component 100, and the operating component 130 of the wire gripper 10 constitute the linkage mechanism 18.

[0294] The first connecting rod member 70 serves as the drive joint for actuating the parallel crank mechanism, and the second connecting rod member 100 serves as the driven joint that actuates via the first connecting rod member 70, which serves as the drive joint. The operating member 130 is connected to the first connecting rod member 70, which serves as the drive joint, and the second connecting rod member 100, which serves as the driven joint, and also serves as a fixed joint that does not actuate in the parallel crank mechanism. The movable gripper 50 is connected to the first connecting rod member 70, which serves as the drive joint, and the second connecting rod member 100, which serves as the driven joint, and also serves as a connecting joint that actuates in the parallel crank mechanism.

[0295] exist Figure 9 The image shows the state in which the covered wire W is clamped from both above and below by a fixed gripper 20 and a movable gripper 50. The movable gripper 50 is rotatably connected above the first link member 70 and the second link member 100 in a manner that allows it to approach and move away from the fixed gripper 20.

[0296] (The function and usage of the interval adjustment mechanism, guiding mechanism, movement restriction mechanism and linkage mechanism)

[0297] Mainly based on Figures 4A-4B This invention will explain the function and usage of the interval adjustment mechanism, guide mechanism, movement restriction mechanism and linkage mechanism of the wire gripper 10 involved in the first embodiment of the present invention.

[0298] When the wire gripper 10 is in the state where the movable gripper 50 is furthest away from the fixed gripper 20 and is hooked onto the covered wire W, such as Figure 2B As shown, the stop portion 344 of the slider 330, which constitutes the interval adjustment mechanism 12 and the movement restriction mechanism 16, is located at the end of the path portion 90 side of the guide portion 80. The screw 334 is rotated so that the engaging guide portion 364 of the slider 330 abuts against the lower edge 86 of the guide portion, thereby fixing the slider 330 to the guide portion 80.

[0299] In this state, lift the wire gripper 10 to the position covering the wire W, as shown. Figure 4A As shown, the covered wire W is positioned between the fixed gripper 20 and the movable gripper 50 of the wire gripper 10.

[0300] At this time, when the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 are maintained in a roughly horizontal direction, the screw 334 of the slider 330 is slightly tilted from the vertical direction towards the push-back side. The front end of the push-back side of the operating member 130 protrudes slightly forward (push-back side) compared to the push-back side of the fixed gripper 20. Consequently, even if the operating member 130 is pulled to the right (pull side) while the fixed gripper 20 is stationary, it will... Figure 4A As shown, the first link assembly 70 and the second link assembly 100 rotate counterclockwise (towards the push-back side) using pivots 126B and 124B as pivots. In conjunction with the movement of pivots 120 and 122, the operating member 130 moves to the lower right. At this time, along with the operating member 130, the position of the stop portion 344 also moves to the lower right. When the stop portion 344 reaches the lower edge 96 of the guide portion 80, the operating member 130 cannot move further to the lower right. The first link assembly 70, the second link assembly 100, and the movable gripper 50 do not move. The operating member 130 and the stop portion 344 function as a movement limiting mechanism 16 operating in this manner.

[0301] At this time, the operating component mounting portion 78 of the first linkage component 70 and the operating component mounting portion 108 of the second linkage component 100 also extend to the push-back side, and the first linkage component 70 and the second linkage component 100 tilt. However, the engaging guide portion 364 of the slider 330 does not lift the guide end edge 86 of the guide portion 80 formed on the pulling side of the first linkage component 70. Therefore, the guide portion 80 and the stop portion 344 function as a movement limiting mechanism 16 that prevents the first linkage component 70, the second linkage component 100, and the movable gripper 50 from moving.

[0302] Next, when securing the covered wire W between the fixed gripper 20 and the movable gripper 50, as follows: Figure 4A and Figure 4BAs shown, by rotating the screw 334 of the slider 330 constituting the interval adjustment mechanism 12 counterclockwise, the engaging guide 364 at the upper end of the screw 334 comes into contact with the guide edge 86 of the guide portion 80. When the screw 334 is rotated counterclockwise further, the guide edge 86 slides in the engaging guide 364 of the slider 330, lifting the guide portion 80. Simultaneously, the first link member 70 and the second link member 100 constituting the interval adjustment mechanism 12 rotate counterclockwise around pivots 124B and 126B, lifting the movable gripper mounting portion 74 side, causing the movable gripper 50 to move upward toward the fixed gripper 20. Therefore, through the functions of the slider 330, the guide portion 80 of the first link member 70, and the second link member 100 constituting the interval adjustment mechanism 12, the movable gripper 50 can be moved toward the fixed gripper 20, securing the covered wire W.

[0303] Furthermore, when shortening the distance between the fixed gripper 20 and the movable gripper 50 according to the wire diameter of the covered wire W, such as Figure 4B As shown, by rotating the screw 334 of the slider 330, a finer coated wire W can be firmly secured.

[0304] At this time, when the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 are maintained in the horizontal direction, the screw 334 of the slider 330 is slightly tilted from the vertical direction toward the push-back side, and the front end of the push-back side of the operating member 130 protrudes considerably rearward (near the center in the width direction of the fixed gripper 20) relative to the push-back side of the fixed gripper 20. Simultaneously, the operating member mounting part 78 of the first link member 70 and the operating member mounting part 108 of the second link member 100 also move toward the pull side, and the first link member 70 and the second link member 100 tilt considerably. Then, the engaging guide part 364 of the slider 330, which rotates the screw 334 upward, lifts the guide end edge 86 of the guide part 80 formed on the pull side of the first link member 70.

[0305] Furthermore, the rotation of the ring 332 of the regulating part 300 is usually achieved by hooking the ring 332 with the hook 702 of the rotating rod 700 (described later) and rotating the rotating rod 700.

[0306] Next, the process of removing the wire gripper 10 from the insulated wire W will be explained.

[0307] By rotating the screw 334 of the slider 330 constituting the interval adjustment mechanism 12 clockwise, the screw 334 descends and comes into contact with the lower edge 96 of the guide section 80. By further rotating the screw 334 of the slider 330 clockwise, the screw 334 of the slider 330 is released, causing the screw 334 to descend. The stop section 344 of the slider 330 is stopped from descending, causing the first linkage component 70 to rotate clockwise with the pivot 126B as the axis. As a result, the movable gripper 50 separates from the fixed gripper 20, and the wire gripper 10 can be pulled away from the wrapped wire W.

[0308] (A variation of the first embodiment)

[0309] like Figures 5 to 9 As shown, the wire gripper 10, a modified example of the first embodiment of this utility model, includes:

[0310] The fixed gripper 20 has a linear pressing part 30;

[0311] The movable gripper 50 has a linear body holding portion 60 that moves toward the linear body pressing portion 30 of the fixed gripper 20; and

[0312] The operating component 130 is connected to the movable gripper 50 via the interval adjustment mechanism 12 and the linkage mechanism 18.

[0313] The interval adjustment mechanism 12 is a mechanism that adjusts the interval between the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 through the guide mechanism 14. The interval adjustment mechanism 12 is mainly composed of a guide protrusion 84, a regulating part 300, a slider 330, a stop part 344 and a locking guide part 364.

[0314] The interval adjustment mechanism 12 has a guide mechanism 14 for guiding the movement restriction mechanism 16, and a movement restriction mechanism 16 for restricting the movement of the movable gripper 50 in order to keep the interval between the linear pressing part 30 of the fixed gripper 20 and the linear holding part 60 of the movable gripper 50 constant.

[0315] The interval adjustment mechanism 12 is provided by a linkage mechanism 18 for moving the movable gripper 50.

[0316] The linkage mechanism 18 mainly consists of a fixed gripper 20, a movable gripper 50, a first linkage component 70, a second linkage component 100, and an operating component 130.

[0317] The first link member 70 constituting the linkage mechanism 18 has a guide portion 80 that extends toward the pulling side of the operating member 130 and constitutes the guide mechanism 14, which is provided in the center or near the center of its length direction.

[0318] The guiding mechanism 14 is mainly composed of the guiding protrusion 84 constituting the guiding part 80, the engaging guiding part 364, and the stopping part 344 of the regulating part 300.

[0319] The movement restriction mechanism 16 is composed of a regulation part 300, which is mounted between the guide part 80 formed in the first connecting rod member 70 and the operating member 130, thus forming a guide mechanism 14.

[0320] The guide portion 80 constitutes the interval adjustment mechanism 12, the guide mechanism 14, and the movement restriction mechanism 16, and includes a guide protrusion 84 constituting the guide mechanism 14, and a path portion 82 that passes through the first linkage member 70 that moves the movable gripper 50 in accordance with the movement trajectory of the first linkage member 70.

[0321] The guide portion 80 has a guide edge 86 formed around the path portion 82.

[0322] The regulating part 300 constituting the interval adjustment mechanism 12 is movably mounted on the operating component 130 near the guide part 80.

[0323] The regulating part 300 is provided with an engaging guide part 364 constituting a movement restriction mechanism 16 in the area where it engages with the guide edge 86 formed around the path part 82, and a stop part 344 constituting a movement restriction mechanism 16 is provided in the area where it engages with the path part 82.

[0324] The guide portion 80 is configured such that, as the regulating portion 300 moves, the connecting rod component moves toward the pulling side and the pushing side of the operating component 130, and stops when the regulating portion 300 stops.

[0325] The regulating part 300 has a slider 330 mounted between the guide part 80, which protrudes from the first link member 70 constituting the linkage mechanism 18 connected to the movable gripper 50, and the operating member 130.

[0326] The slider 330 is mounted near one end of the operating component 130, and the slider 330 is configured to move freely in the direction of the movable gripper 50 and the operating component 130.

[0327] The slider 330 has an engaging guide portion 364 at its other end that engages with the guide end edge 86 formed around the guide portion 82 of the guide portion 80.

[0328] The regulating part 300 is configured such that, when the movable gripper 50 is closed and / or open, the first link member 70 is fixed in a constant position by stopping the engaging guide part 364 that engages with the guide part 80.

[0329] The slider 330 is mounted on the operating member 130 near one end, and the slider 330 is configured to move freely in the direction of the movable gripper 50 and the operating member 130. At its other end, it has a pin-shaped stop portion 344 that engages with the path portion 82 of the guide portion 80.

[0330] The stop part 344 is configured to act as a movement restriction mechanism 16 that engages with the path part 82 to restrict the movement of the linkage component when the movable gripper 50 is in the open state.

[0331] The guide portion 80 is configured to match the movement trajectory of the linkage member that moves the movable gripper 50, and extends from the pull side to the push-back side of the operating member 130, a guide protrusion 84 having a semi-circular arc-shaped guide edge 86 extending from the pull side to the push-back side of the operating member 130.

[0332] The guide edge 86 of the guide portion 80 constitutes an interval adjustment mechanism 12, which is formed on the lower edge of the guide protrusion 84 surrounding the path portion 82 of the guide portion 80. It is configured to move along a semi-circular arc trajectory as the engaging guide portion 364 of the regulating portion 300 moves, from the pulling side of the operating member 130 to the pushing side or from the pushing side of the operating member 130 to the pulling side.

[0333] The regulating part 300 is configured such that, when the movable gripper 50 is changed from a closed state to an open state, the engaging guide part 364 located at or near the end of the guide edge 86 on the push-back side of the path portion 82 constituting the guide part 80 moves toward the pull side, and / or when the movable gripper 50 is changed from an open state to a closed state, the engaging guide part 364 located on the side of the guide edge 86 constituting the guide part 80 that is farther away from the pull side than the end of the path portion 90 moves toward the push-back side.

[0334] Regarding this configuration, it is no different from the cable gripper 10 in the first embodiment. The cable gripper 10, which is a variation of the first embodiment, is different only in the configuration of the guide portion 80 that forms the interval adjustment mechanism 12, the guide mechanism 14 and the movement restriction mechanism 16 in the first link member 70 that constitutes the linkage mechanism 18.

[0335] Therefore, the description here will focus on the guide portion 80 formed in the first link member 70, and the description of other components will be omitted.

[0336] In the first embodiment, the guide portion 80 of the main body portion 72 of the first link member 70 is formed in a ring shape, and a generally elliptical path portion 82 is formed on its inner side. However, in the variation of the first embodiment, the guide portion 80 is not connected to the side opposite to the main body portion 72 of the link member, but is formed in an open state.

[0337] In a variation of the first embodiment, the guide portion 80 is composed of a straight upper edge 92 of a path portion extending in a near-horizontal direction from the upper side of the guide protrusion 84, and a mouth-shaped guide protrusion 84 extending from the main body portion 72 of the connecting rod member opposite to the upper edge 92 of the path portion.

[0338] The minor path 82 is formed between the upper edge 92 of the minor path, which is formed by cutting off a part of the main body 72 of the connecting rod component, and the lower edge 96 of the minor path of the guide protrusion 84.

[0339] In the guide protrusion 84, the upper edge of the upper guide protrusion 84 forms a lower edge 96 of a path portion extending in an arc shape, and the lower edge of the lower guide protrusion 84 forms a lower edge 86 of a guide portion extending in an arc shape.

[0340] That is, in the guide protrusion 84, the lower edge 86 of the guide portion surrounding the lower side of the guide protrusion 84 is generally arc-shaped, and the lower edge 96 of the guide portion surrounding the upper side of the guide protrusion 84 is generally arc-shaped.

[0341] In the guide section 80, the upper edge 92 of the path section of the main body 72 of the connecting rod component constituting the guide protrusion 84 is a straight line that extends approximately parallel to the center of the lower edge 96 of the path section of the guide protrusion 84. From the center to the front end of the guide protrusion 84, an open type path section 82 without the upper edge 92 of the path section is formed.

[0342] The lower edge 86 of the guide portion of the first link component 70 can slidably contact the engaging guide portion 364 of the retaining portion 340, and is configured to be lifted by the screw 334 of the slider 330.

[0343] (Fire wire separation tool)

[0344] Regarding the method of using the wire gripper 10 involved in this utility model, the focus is on its use as a wire separating tool 1000 in the wire separating process, and it is mainly based on... Figure 9 Please provide an explanation.

[0345] like Figure 9As shown, the live wire separating tool 1000 is a tool with a pair of first wire grippers 10A and second wire grippers 10B installed at both ends of the rod-shaped telescopic member 500. After the covered wire W is held by the pair of first wire grippers 10A and second wire grippers 10B, the covered wire W is bent and cut.

[0346] The pair of first wire grippers 10A and second wire grippers 10B installed at both ends of the rod-shaped telescopic member 500 of the wire separating tool 1000 according to the second embodiment of the present invention are both wire grippers 10 according to the first embodiment of the present invention.

[0347] The 1000-type wire separating tool includes a 500-type rod-shaped telescopic tool:

[0348] The cylindrical body 510 has a first mounting portion 512 at one end for mounting the first wire gripper 10A;

[0349] The first wire support 600 is mounted on the cylindrical body 510 by mounting the cylindrical body 510 to the mounting part 602;

[0350] The telescopic body 520 has a second mounting portion 522 for mounting the second wire gripper 10B at one end, and the end side opposite to the second mounting portion 522 is built into the cylindrical body 510 and telescopic relative to the cylindrical body 510.

[0351] The second wire support 610 is installed on the telescopic body 520 by installing the telescopic body 520 on the mounting part 612;

[0352] The reinforcing part (not shown) is installed on the telescopic body 520; and

[0353] A reciprocating shaft (not shown) is screwed into a reinforcing section (not shown).

[0354] like Figure 9 As shown, in the cylindrical body 510,

[0355] It has a generally cylindrical side portion 514 formed in the shape of a cylinder protruding from its side.

[0356] It has a side cylindrical hole (not shown) formed from an opening at the end of the side cylindrical portion 514 toward the interior of the cylindrical body 510.

[0357] An input shaft 516, which is rotatably inserted into a side cylindrical hole (not shown), has an input portion 518 at one end.

[0358] The input shaft 516 has a first bevel gear (not shown) mounted at the end opposite to the input section 518.

[0359] It has a second bevel gear (not shown) mounted on a reciprocating shaft (not shown) and meshing with a first bevel gear (not shown).

[0360] The reciprocating shaft (not shown) rotates the first bevel gear (not shown) mounted on the end opposite to the input portion 518 of the input shaft 516 by rotating the input portion 518 of the input shaft 516, thereby rotating when the second bevel gear (not shown) rotates.

[0361] When the reciprocating shaft (not shown) rotates, the reinforcing part (not shown) that is screwed into the reciprocating shaft (not shown) and the telescopic body 520 that is installed on the reinforcing part (not shown) and can extend and retract freely relative to the cylindrical body 510 extend and retract relative to the cylindrical body 510.

[0362] When the telescopic body 520 installed on one of the reinforcing parts (not shown) and the other reinforcing part (not shown) extends or retracts relative to the cylindrical body 510,

[0363] The distance between the first wire gripper 10A installed in the first mounting part 512 of the cylindrical body 510 and the second wire gripper 10B installed in the second mounting part 522 of the telescopic body 520 can be extended.

[0364] The live wire separating tool 1000 uses a rod-shaped telescopic tool 500 to insert the wrapped wire W into the... Figure 9 The first wire support 600 shown has a first wire insertion area 604 for inserting the covering wire W and Figure 9 After the second wire support 610 shown is inserted into the second wire insertion area 614 for inserting the covered wire W, the covered wire W is held by holding the first part P1 of the covered wire W with the first wire gripper 10A and holding the second part P2 of the covered wire W with the second wire gripper 10B.

[0365] like Figure 9 As shown, by hooking the ring portion 332 of the slider 330 with a hook 702 formed at at least one end of the rotating rod 700 and rotating the ring portion 332 of the slider 330, the first wire gripper 10A holds the first portion P1 of the wire W.

[0366] By hooking the ring portion 332 of the slider 330 with a hook 702 formed at at least one end of the rotating bar 700 and rotating the ring portion 332 of the slider 330, the second wire gripper 10B holds the second portion P2 of the wire W, which is different from the first portion P1.

[0367] After the wire separating tool 1000 holds the first part P1 of the wrapped wire W using the first wire gripper 10A and the second part P2 of the wrapped wire W using the second wire gripper 10B, it shortens the length of the portion of the telescopic body 520 that is exposed outside the cylindrical body 510 by rotating the input part 518 of the input shaft 516. This shortens the distance between the first wire gripper 10A and the second wire gripper 10B, causing the portion between the first wire support member 600 on the right side and the second wire support member 610 on the left side of the wrapped wire W to bend in a direction opposite to the cylindrical body 510. The bending portion is then cut off by the cutting blade, thereby cutting the wrapped wire W.

[0368] Since the live wire separating tool 1000 itself does not have a cutting blade to cut the insulated wire W, the live wire separating tool 1000 can also be called a wire cutting auxiliary component. Alternatively, a cutting blade to cut the insulated wire W can be provided in the live wire separating tool 1000.

[0369] As described above, the embodiments of the present invention have been disclosed in the above description, but the present invention is not limited thereto.

[0370] That is, various changes can be made to the above-described embodiments in terms of mechanism, shape, material, quantity, position or configuration without departing from the technical concept and purpose of this utility model, and these changes are all included in this utility model.
