A limiting block 19 is fixedly sleeved on the fixing column 20. A spring 17 is sleeved on the fixing column 20. The spring 17 is located between the second slider 16 and the limiting block 19. According to the inner core diameter of the wire, the wire head to be cut is placed on the appropriate arc-shaped cutting edge 24 of the lower cutter 4. The driving mechanism drives the first slider 10 to move. The first slider 10 drives the roller 7 to move synchronously through the mounting seat 8. The roller 7 rolls on the top of the guiding block 15. When the roller 7 moves along the inclined surface of the guiding block 15, the guiding block 15 is continuously pressed down, and the upper cutter 6 is also pressed down synchronously until cutting operation is achieved in cooperation with the lower cutter 4. When the roller 7 moves along the horizontal plane of the guiding block 15, the cutting position of the upper cutter 6 and the lower cutter 4 can be maintained. At this time, the wire skin of the wire head is removed, and the wire can be drawn out, so that wire head peeling operation can be realized; when the roller 7 returns, the upper cutter 6 rises and separates from the lower cutter 4, and the operation is very simple without manual operation with a wire stripping pliers.

When the roller 7 moves along the inclined surface of the guiding block 15, the guiding block 15 is continuously pressed down, and the upper cutting knife 6 is also pressed down synchronously until it cooperates with the lower cutting knife 4 to complete the cutting operation. When the roller 7 moves along the horizontal plane of the guiding block 15, the cutting position of the upper cutting knife 6 and the lower cutting knife 4 can be maintained. At this time, the wire skin at the head of the electric wire is removed, and the electric wire can be pulled out, so that the wire head stripping operation can be realized; when the roller 7 returns, the upper cutting knife 6 rises and separates from the lower cutting knife 4. The operation is very simple and there is no need to manually hold a wire stripping pliers for operation; the waste head after cutting enters the recycling box 3 for recycling through the discharge hole 25; the marking plate 5 is used to mark the electric wire inner core diameter parameter cut by the arc-shaped cutting edge 24.
