DETAILED DESCRIPTION

[0019] The split wire stripper consists of an assembly frame 1, a driving handle 2, a clamping head 3, a cutting head 4, a driving screw rod 5, a connecting plate A6 and a driving rack 7 (see the attached manual). Figure 1 ).

[0020] The assembly frame 1 is symmetrically slidably provided with a connecting plate A6 and a connecting plate B21; a driving screw 5 is movably provided in the middle of the assembly frame 1 through a bearing; the driving screw 5 is respectively threadedly connected with the connecting plate A6 and the connecting plate B21 (see the attached manual). Figure 1 ); when the driving screw rod 5 rotates forward, the connecting plate A6 and the connecting plate B21 can be driven to separate from each other along the assembly rack 1; when the driving screw rod 5 rotates reversely, the connecting plate A6 and the connecting plate B21 can be driven to move closer to each other along the assembly rack 1.

[0021] The middle part of the driving screw rod 5 is provided with a driving gear 8 (see the attached manual). Figure 2 The drive handle 2 is slidably mounted on the assembly rack 1 above and below the drive gear 8 through the guide slide rod 9; a return support spring 10 is connected between the drive handle 2 and the assembly rack 1 (see the attached manual). Figure 2 ).

[0022] Two sets of driving racks 7 are meshed and connected on both sides of the driving gear 8; one set of driving racks 7 is fixedly connected to one set of driving handles 2; the other set of driving racks 7 is fixedly connected to another set of driving handles 2 (see the attached manual). Figure 2). In this way, when the two sets of driving handles 2 are held by hand and brought close to each other after overcoming the elastic force of the return support spring 10, the driving handles 2 can drive the driving screw 5 to rotate forward through the driving rack 7 and the driving gear 8; during the forward rotation of the driving screw 5, the connecting plate A6 and the connecting plate B21 can be driven to separate from each other along the assembly frame 1.

[0023] One end of the connecting plate A6 is equipped with a clamping head 3 (see the appendix of the instruction manual). Figure 1 ); The clamping head 3 is composed of a support frame B25, a fixed tooth plate 18, a movable tooth plate 19 and a control rod B20 (see the attached manual Figure 3 ).

[0024] A support frame B25 is fixedly mounted on one end of the connecting plate A6; a fixed tooth plate 18 is fixedly mounted inside the support frame B25; a movable tooth plate 19 is slidably mounted in the support frame B25 on one side of the fixed tooth plate 18 through a slide rail; a separation tension spring 16 is connected between the movable tooth plate 19 and the support frame B25; an anti-wear roller 17 is movably mounted on one side of the movable tooth plate 19 (see the attached manual Figure 3 and 5 ).

[0025] Under the action of the elastic force of the separation tension spring 16, the anti-wear roller 17 on the movable tooth plate 19 always maintains a rolling connection with the control rod A14; thus, when the control rod A14 is actuated, the anti-wear roller 17 can control the back and forth movement of the movable tooth plate 19.

[0026] One end of the connecting plate B21 is equipped with a cutting head 4 (see the appendix of the instruction manual). Figure 1 ); The cutting head 4 is composed of a support frame A11, a cutting fixed plate 12 and a cutting movable plate 13 (see the attached manual Figure 2 ).

[0027] A support frame A11 is fixedly mounted on one end of the connecting plate B21; a cutting plate 12 is fixedly mounted inside the support frame A11; a cutting movable plate 13 is slidably mounted in the support frame A11 on one side of the cutting plate 12 through a slide rail; a separation tension spring 16 is connected between the cutting movable plate 13 and the support frame A11 (see the attached manual). Figure 2 A wear-resistant roller 17 is movably mounted on one side of the cutting plate 13 (see the attached manual). Figure 3 and 4 ).

[0028] Under the action of the elastic force of the separation tension spring 16, the anti-wear roller 17 on the cutting movable plate 13 always maintains a rolling connection with the control rod B20; thus, when the control rod B20 is actuated, the back and forth movement of the cutting movable plate 13 can be controlled by the anti-wear roller 17.

[0029] A plurality of semicircular cutouts 15 of different diameters are arranged facing each other between the cutting fixed plate 12 and the cutting movable plate 13 (see the attached manual for details). Figure 2 ).

[0030] When the cutting fixed plate 12 and the cutting movable plate 13 are buckled, a cutting ring is formed between the semicircular cutouts 15 arranged opposite to each other. The diameter of each cutting ring is consistent with the diameter of the metal core of various types; thus, when the cutting movable plate 13 and the cutting fixed plate 12 are buckled, the insulating layer (i.e., outer skin) on the wire can be cut off through the corresponding cutting ring without damaging the metal core.

[0031] The clamping head 3 and the cutting head 4 are arranged facing each other; the assembly frame 1 between the clamping head 3 and the cutting head 4 is respectively equipped with a control rod A14 and a control rod B20 (see the appendix of the manual Figure 1 ).

[0032] The control rod B20 extends to the inside of the support frame A11 of the cutting head 4; the control rod B20 is rollingly connected to the anti-wear roller 17 of the cutting head 4. The control rod A14 extends to the inside of the support frame B25 of the clamping head 3; the control rod A14 is rollingly connected to the anti-wear roller 17 of the clamping head 3.

[0033] The control rod A14 and the control rod B20 are both of an integrated structure; they are composed of an extrusion section 22, a transition section 23 and a return section 24; one end of the transition section 23 is provided with the return section 24; the other end of the transition section 23 is provided with the extrusion section 22; the extrusion section 22 and the return section 24 are both arranged horizontally; the transition section 23 is arranged in an inclined shape and is connected to the extrusion section 22 and the return section 24 in a circular arc transition (see the attached manual Figure 6 ). The purpose of setting the control rod A14 and the control rod B20 in this way is that during the separation process of the clamping head 3 and the cutting head 4, the control rod A14 can squeeze the movable tooth plate 19 through the anti-wear roller 17 to make it close to the fixed tooth plate 18; at the same time, the control rod B20 can squeeze the cutting movable plate 13 through the anti-wear roller 17 to make it close to the cutting fixed plate 12.

[0034] When the split wire stripper is working, the wire to be stripped is first passed through the fixed tooth plate 18 and the movable tooth plate 19 of the clamping head 3 and the fixed cutting plate 12 and the movable cutting plate 13 of the cutting head 4 in sequence. Then the wire stripper is adjusted so that the fixed cutting plate 12 and the movable cutting plate 13 are aligned with the cutting position of the wire, and the wire is aligned with the corresponding cutting ring.

[0035] After the above preparations are completed, the two sets of driving handles 2 are clamped by hand to overcome the elastic force of the return support spring 10 and move closer to each other. When the driving handles 2 move closer to each other, the driving rack 7 and the driving gear 8 can drive the driving screw 5 to rotate forward; during the forward rotation of the driving screw 5, the connecting plate A6 and the connecting plate B21 can be driven to separate from each other along the assembly frame 1.

[0036] During the separation process of the connecting plate A6 and the connecting plate B21, the clamping head 3 and the cutting head 4 can be driven to separate from each other; during this process, the control rod B20 can squeeze the anti-wear roller 17 and the cutting movable plate 13 through the extrusion section 22, so that they are close to the cutting fixed plate 12 to complete the cutting of the insulation layer of the wire; at the same time, the control rod A14 can squeeze the anti-wear roller 17 and the movable tooth plate 19 through the extrusion section 22, so that they can clamp the wire with the cooperation of the fixed tooth plate 18.

[0037] After the cutting movable plate 13 cuts off the insulation layer of the wire, continue to clamp the two sets of driving handles 2 so that they continue to move closer to each other; in this way, the clamping head 3 and the cutting head 4 can continue to separate; in this way, the clamping head 3 can clamp and fix the wire; the cutting head 4 can drive the cut insulation layer away from the previous position along the wire, thereby completing the wire stripping work.

[0038] Then, the driving handle 2 is released. After the driving handle 2 is released, the separation type wire stripping pliers can be quickly reset under the action of the elastic force of the separation tension spring 16 and the return support spring 10; the separation type wire stripping pliers can enter the next working cycle.

[0039] The detachable wire stripping pliers has a compact structure and an ingenious design. When working, the clamping head 3 and the cutting head 4 can be separated by holding and clamping the two sets of driving handles 2. During the separation of the clamping head 3 and the cutting head 4, the wire stripping work can be completed. Since the detachable wire stripping pliers can directly complete the wire stripping work by holding the driving handles 2 during the working process, no operating skills are required, thereby solving the problem of low safety caused by the difficulty in controlling the force when using the existing wire stripping pliers, and meeting the needs of power workers.
