A handle 1 is provided; in the middle of the handle 1 are respectively provided with a fixed pincer head 2 fixed on the top and a movable pincer head 3 pinned on the top; specifically, a groove is opened in the middle of the handle 1, and the upper end of the movable pincer head passes through the pin shaft 3a is inserted into the groove and connected with the handle 1. Both the fixed pliers 2 and the movable pliers 3 adopt a V-shaped structure, and there are opposite V-shaped notches on the inner side of the middle, and a diamond-shaped strip is formed between the two V-shaped notches. Cable port;

A locking handle 4 with a pin shaft is arranged outside the bottom of the movable pliers 3; A return spring 5 set on the pin shaft of the locking handle 4 is arranged between the bottoms of the pliers 3; the locking handle 4 is threaded in the fixed pliers 2 and the movable pliers 3 with its pin shafts, and is movable The bottom of the clamp head 3 is pressed against the return spring 5 to form a locking force on the bottom of the fixed clamp head 2, thereby forming a locking structure for the cable 8 in the diamond-shaped cable stripping port;

A rotary cutting adjustment handle 6 with a pin shaft is arranged outside the middle part of the fixed pliers head 2; a rotary cutting spring 6a and a rotary cutting blade are arranged on the top of the pin shaft of the rotary cutting adjustment handle 6; the rotary cutting spring 6a and the rotary cutting blade It can be located in the fixed pliers head 2, and the rotary cutting adjustment handle 6 is screwed into the fixed pliers head 2 with its pin shaft, and the rotary cutting blade is pushed by the rotary cutting spring 6a at the top of the pin shaft to form a pair in the diamond-shaped cable stripping opening. Radial rotary-cut structure of cable wire 8 insulation;

The outer middle side of movable pliers head 3 is provided with the sectioning adjustment handle 7 with bearing pin; The top of the bearing pin of sectioning adjustment handle 7 is provided with sectioning spring 7a and sectioning blade; Sectioning spring 7a and sectioning The blade can be in the movable pliers head 3, and the cutting adjustment handle 7 is screwed in the movable pliers head 3 with its pin shaft, and the cutting spring 7a at the top of the pin shaft pushes the cutting blade to form a pair of diamond-shaped stripping cables.
