The upper end of the fixed plate 2 is slidably connected with a sliding plate 3. The top end of the sliding plate 3 is fixedly connected with a connecting block 4. The inner side of the connecting block 4 is fixedly connected with a mounting railing 5. The inner surface of the mounting railing 5 is bolted with a limiting fixture 6, a peeling tool 7 and a cutting tool 8. The limiting fixture 6, the peeling tool 7 and the cutting tool 8 are arranged in sequence from front to back. By providing the limiting fixture 6, the peeling tool 7 and the cutting tool 8, the limiting fixture 6 can limit and fix the wire, the peeling tool 7 can cut the outer skin of the wire to facilitate wire peeling, and the cutting tool 8 can cut the wire, thereby improving the functionality and stability of the device. The middle part of the top end of the top plate 1 is fixedly connected with a limiting frame 9. The upper end of the connecting block 4 is fixedly connected with a limiting block 10. The inner side of the limiting block 10 is fixedly connected with a limiting column 11. The outer surface of the limiting column 11 is slidably connected with the opening on the limiting frame 9, which is convenient for improving the docking stability of the limiting fixture 6, the peeling tool 7 and the cutting tool 8 and enhancing the overall stability and reliability.

[0023] In another embodiment provided by the present utility model, as Figures 1-4As shown, a retaining plate 12 is fixedly connected to the middle of the top plate 1. A waste opening 13 is provided in the middle of the top plate 1. The sizes of the retaining plate 12 and the waste opening 13 are the same, preventing the leather shell from remaining at the junction of the retaining plate 12 and the waste opening 13, ensuring the stable collection of the leather shell. A support plate 15 is fixedly connected to the bottom end of the waste opening 13. A bottom plate 16 is fixedly connected to the bottom end of the support plate 15. A waste box 14 is slidably connected to the upper end of the bottom plate 16. By providing the retaining plate 12 and the waste opening 13, the leather shell can be collected after the device finishes peeling. Finally, the leather shell is collected through the waste box 14, facilitating the stable and reliable operation of the device, improving the overall cleanliness and functionality of the device. An electric push rod 17 is fixedly connected to the outer surface of the support plate 15. The output end of the electric push rod 17 is fixedly connected to a sliding frame 18. A positioning column 19 is fixedly connected to the top end of the sliding frame 18. The top end of the positioning column 19 is fixedly connected to the bottom end of the sliding plate 3. The outer surface of the positioning column 19 is slidably connected to the slots on the top plate 1 and the fixing plate 2, further improving the sliding stability of the sliding plate 3 and the connecting block 4.

The waste box 14 is located directly behind the waste opening 13, facilitating the collection of the leather shell and improving the overall cleanliness.

[0024] Working principle: The wire is fed in through an external mechanism between the limit clamp 6, the peeling tool 7 and the shearing tool 8, and sent out through the opening on the limit frame 9. The electric push rod 17 is started. The output end of the electric push rod 17 drives the sliding plate 3 and the connecting block 4 to move left and right through the sliding frame 18 and the positioning column 19. Under the shock absorption of the shock absorber 20 and the limiting action of the limiting column 11 and the limit frame 9, the limit clamp 6, the peeling tool 7 and the shearing tool 8 are driven to approach the wire. The limit clamp 6 can limit and fix the wire. The peeling tool 7 can cut the outer skin of the wire, facilitating the peeling of the wire. The shearing tool 8 can cut the wire. Pull the wire body forward to complete the peeling of the front end of the cut wire. The peeled leather shell enters the waste box 14 through the retaining plate 12 and the waste opening 13, completing the peeling and shearing of the wire.
