The threads in opposite directions are respectively threadedly penetrated and connected to the two groups of sliders 401 on the same side, an inner groove 501 is arranged inside the bending rod 5 near the outer end, the threaded pin 6 movably penetrates the bending rod 5 and extends to the inner groove 501, two groups of plug-in rods 502 are fixedly connected to the inner wall of the inner groove 501, and the two groups of plug-in rods 502 are both movably penetrated through the inner end of the threaded pin 6, the outer end of the bending rod 5 is rotatably connected with a threaded sleeve 503, and the threaded sleeve 503 is threadedly sleeved on the outer side of the threaded pin 6, the bending rod 5 and the mounting plate 3, and the adjusting rod 10 and the bending rod 5 and the movable plate 9 are rotatably connected through a rotating pin, the outer end of the bending plate 11 is rotatably connected with two groups of first threaded rods 1101, and the first threaded rod 1101 is threadedly penetrated and connected to the movable plate 9, the upper end of the bending plate 11 is threadedly penetrated and connected to the second threaded rod 1102, and the bottom of the second threaded rod 1102 is rotatably connected to the extrusion block 1103.

[0023] Based on the above structure, when the device is in use, a standard or irregular sheet material is placed on the upper end of the fixed platform 1, and then the motor 402 is started to drive the rotating shaft 4 to rotate, and the threads in opposite directions on the outer side of the rotating shaft 4 drive the sliders 401 on the same side of the two sets of mounting plates 3 to slide relative to each other, thereby driving the two sets of mounting plates 3 to move relative to each other and gradually approach the two ends of the sheet material.
