Bosses are respectively arranged on one side of two end parts of the notch of the upper through groove and fixedly connected with the outer wall of the shell 1, wherein one boss is provided with a vertical shaft lever, and the other boss is provided with an inserting hole; two sides of the upper blade 2 are correspondingly provided with wing plates with two bosses, through holes are formed in the wing plates, one wing plate is rotationally connected with the boss through a shaft rod, and the other wing plate is spliced with the other boss through a pin 6.
The outside end of the lower blade 3 is fixedly provided with a transverse plate, a spring is arranged between the transverse plate and the blade shell 5, and the length of the transverse plate is larger than the groove width of the lower through groove.
The handle 8 is arranged outside the closed end of the shell 1, and the handle 8 is T-shaped.
When the wing plate of the upper blade 2 is spliced with the pin 6, the cutting edge of the upper blade 2 extends to the outer side of the copper core in the leaky cable; the edge of the lower blade 3 extends to the inner side of the sheath of the leaky cable.
When the cable stripping machine is used, the upper blade 2 is firstly opened, the end part of a cable is plugged into the shell 1, the lower blade is extruded into the blade shell 5 under the action of the spring, the end part of the cable is not affected, then the upper blade 2 is rotated, the cutting edge of the upper blade is pressed into the copper core of the cable, the upper blade 2 is fixed by the pin 6, and then the shell 1 is rotated, so that the cable stripping work of the end part of the cable is realized.
Example 2
