[0027] A sliding block 10 is provided on the surface of the threaded rod 8, and the sliding block 10 is threadedly connected to the threaded rod 8;

[0028] When the device is in use, the motor 7 is turned on to drive the threaded rod 8 to rotate. Since the threads on both sides of the threaded rod 8 are opposite, the sliding blocks 10 on both sides move inward at the same time.

[0029] A fixing plate 9 is disposed at the upper end of the sliding block 10, and a force-bearing plate 11 is disposed on the side of the fixing plate 9;

[0030] When the device is in use, the threaded rod 8 drives the sliding blocks 10 on both sides to move inward at the same time, thereby driving the fixed plate 9 to move inward at the same time, so that the fixed plate 9 pushes the force-bearing plate 11 to fit with the raised two sides of the strip body 21 to block the strip body 21, thereby preventing the strip body 21 from rebounding and improving the processing quality of the strip body 21.

[0031] A fixing bolt 16 is provided at the upper end of the die 15, the fixing bolt 16 penetrates the die 15, and the fixing bolt 16 is threadedly connected to the base 1;
