The two springs are connected at one end to the inner wall of the mounting hole and at the other end to the movable plate. They can play a certain buffering role during the wire stripping process. When encountering some unforeseen external impact or uneven cable material, it can reduce the damage to the cutting blade and the entire wire stripper structure, and also help maintain the relatively stable working state of the cutting blade.

[0028] Example 3

[0029] Please refer to the accompanying drawings in the specification. In this embodiment of the utility model, a novel wire stripper includes a first wire stripper 1 and a second wire stripper 2, which are hinged together by a hinge shaft 3. This connection method makes the wire stripper more flexible and smooth during opening and closing operations, allowing users to control the opening and closing angle of the wire stripper according to actual needs, so as to adapt to the wire stripping operation of cables of different thicknesses. The bottom end of the first wire stripper 1 is provided with a first handle 4, and there is a first connecting block 6 between the first handle 4 and the first wire stripper 1. The bottom end of the second wire stripper 2 is provided with a second handle 5, and there is a second connecting block 7 between the second handle 5 and the second wire stripper 2.

[0030] The first connecting block 6 and the second connecting block 7 are provided with a branching assembly. The branching assembly includes an upper tapered roller 8, a lower tapered roller 9, an upper tapered roller 10, a lower tapered roller 11, and a cutting blade 12. Both the first connecting block 6 and the second connecting block 7 have mounting grooves. The upper tapered roller 8 and the lower tapered roller 9 are disposed in the mounting groove of the first connecting block 6. Each of the upper tapered roller 8 and the lower tapered roller 9 is provided with a guide rod 13, and both the upper tapered roller 8 and the lower tapered roller 9 are respectively mounted on the first connecting block 6 via the guide rod 13. There is a certain gap between the first roller 9 and the second tapered roller 11; the second connecting block 7 is provided with the second upper tapered roller 10, the second lower tapered roller 11 and the cutting blade 12 in the mounting groove. The second upper tapered roller 10 and the second lower tapered roller 11 are both provided with guide rods 14, and the second upper tapered roller 10 and the second lower tapered roller 11 are respectively set on the second connecting block 7 through the guide rods 14. The cutting blade 12 is set between the second upper tapered roller 10 and the second lower tapered roller 11. The dividing assembly is composed of the first upper tapered roller, the first lower tapered roller, the second upper tapered roller, and the second lower tapered roller. The tapered roller design helps to better conform to the cable and guide it into the appropriate stripping position. The gap between the different rollers helps to position and organize the cable, facilitating accurate stripping operations. Furthermore, the cutting blade is positioned between the upper and lower tapered rollers, allowing for precise cutting and separation of the wire core and insulation while separating the wires. This integrated wire separating and cutting functions improves stripping efficiency and accuracy.

[0031] The second connecting block 7 is provided with a blade adjustment assembly, one side of which is connected to the cutting blade 12.

[0032] The blade adjustment assembly includes a pusher 19, and the second connecting block 7 is provided with a pusher sliding groove 20. The pusher 19 is disposed in the pusher sliding groove 20, and the front end of the pusher 19 is fixedly connected to the cutting blade 12. The pusher and its front end are fixedly connected to the cutting blade. When adjusting the position of the cutting blade and stripping the wire, the pusher can assist the blade to move and apply force better, further enhancing the stability of the blade adjustment and wire stripping operation.

[0033] Example 4

[0034] The first connecting block 6 is equipped with a current testing component. The current testing component does not include the upper tapered roller 8 and the lower tapered roller 9. The current testing component includes a housing 23, a cover plate 24, a button battery, a circuit board, and a spring sheet 25. The first connecting block 6 has a tooling hole, and the housing 23 is disposed in the tooling hole. The button battery is mounted on the circuit board, which is disposed inside the housing 23. The spring sheet 25 is disposed on the circuit board, with one end of the spring sheet 25 extending through the housing 23 to the outside of the housing 23 and contacting the first connecting block 6. The spring sheet is a metal spring sheet. The circuit board is equipped with a red light and a green light. By setting the spring sheet on the circuit board to contact the clamp body, when the wire stripper contacts the wire and conducts electricity, the red light and green light on the circuit board will light up depending on whether it is a live wire or a neutral wire. If it is a live wire, the red light will light up; if it is a neutral wire, the green light will light up.

[0035] Working Principle: First, when the user grasps the first and second handles and applies pressure to bring them close together, the first and second wire stripping clamps close via a hinge shaft, clamping the cable between them. This step is similar to the clamping action of ordinary pliers, providing stable support for subsequent wire stripping operations. After clamping the cable, as the wire stripping clamps close, the cable enters the wire separating assembly area on the first and second connecting blocks. Upper and lower tapered rollers 1 and 2 surround the cable. Because they are tapered rollers, they can accommodate cables of different thicknesses and can initially separate the cable insulation from the core, guiding the insulation and core into the appropriate position. Simultaneously, the gap between the rollers helps to position the cable, preventing it from shifting during stripping. Based on the wire separating, the cutting blade located between upper and lower tapered rollers 2 begins to work. As the wire stripping clamps close further, the cutting blade cuts into the cable insulation, slicing it open. Because the blade is positioned relatively fixed in a reasonable location within the wire splitting assembly, and can be fine-tuned by adjusting the blade, it can precisely cut the insulation sheath without damaging the wire core as much as possible.

[0036] In the above process, this utility model uses a hinged shaft connection, allowing for flexible opening and closing and convenient control of the stripping angle. The tapered rollers of the wire separating assembly can fit the cable well, accurately positioning and separating the wire core from the insulation sheath. The cutting blade is located between the rollers, allowing for precise cutting of the insulation sheath without damaging the wire core; the blade adjustment assembly can adjust the blade position via a rotating component and a threaded rod, and can also utilize a spring to buffer external impacts, protecting the blade and the wire stripper structure. The pushing component assists in the movement and force application of the blade, enhancing the stability of adjustment and stripping operations; the folding component at the handle allows the wire stripper to be folded when not in use, reducing its space occupation and making it convenient for carrying and storing when working outdoors.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
