The two positioning frames 7 form a longitudinal positioning surface, and the two swing frames 9 form a transverse swing surface.

[0030] The other ends of the two swing frames 9 are connected through a connecting plate 10, and the connecting plate 10 is fixedly connected with a linear module that drives the tug-wire clamp 2 to move in the same direction or in the opposite direction. The linear module drives the tug-wire clamp 2 to move in the same direction or in the opposite direction, and drives the tug-wire clamp 2 to clamp the cut-off outer skin part of the shielded high-voltage line. A positioning seat 11 is fixedly connected to the end of the connecting plate 10, and an offset component is connected between the positioning seat 11 and the driving plate 6.

A positioning frame 7 is provided directly above the material receiving box 17 and directly below the cable.

The first cylinder 12 retracts, driving one end of the pull wire clamp 2 to deviate from the axis of the shielded high-voltage wire. The driving motor 4 drives the main shaft to rotate (forward and reverse) to generate a deflection force to completely break the cut of the aluminum foil layer on the cable. The outer skin and aluminum foil are then removed through the second moving assembly. After the outer skin and aluminum foil are removed, they fall into the receiving box 17 under the action of gravity. This new aluminum foil removal process is applicable to both silicone wire and cross-linked wire, with a short processing time and neat aluminum foil breaks without residue.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
