Directions continue to cut the wire's lamination. Driven by the conveying mechanism 540, the peeling mechanism 520 moves along the extending direction of the wire, so that the peeling mechanism 520 can continuously peel off the film along the wire axis, increasing the length of the core wire leaking out, which is convenient for later cutting and use.

In order to make the film fragments fall into the accommodating cavity 5101, the conveying mechanism 540 can drive the peeling mechanism 520 to move away from the pulling direction of the wire, so that the cut film is located in front of the mouth end of the cutting mechanism, and will not into the guide hole.

In order to make the electric wire in a state of being stretched when the stripping mechanism 520 cuts the electric wire, the stripping mechanism 520 and the cutting casing 510 jointly tension the electric wire. It can be understood that the hole wall of the threading hole 5102 can exert frictional force on the outer surface of the wire to prevent the wire between the stripping mechanism 520 and the threading hole 5102 from loosening, thereby preventing the stripping mechanism 520 from cutting the core wire.

In this way, the electric wire between the stripping mechanism 520 and the threading hole 5102 is kept in a tensioned state by the frictional force of the outer surface of the wire through the damping member 560, so as to prevent the electric wire from shaking or loosening. In this embodiment, the damping member 560 is a rubber member, and the damping member 560 is inserted through the threading hole 5102 to increase the contact area with the wire, thereby increasing the frictional force with the wire.
