A synchronous belt 605 is meshed on the surface of the synchronous pulleys. Protective covers are arranged on both sides of the synchronous belt 605. The position of the synchronous belt 605 is fixed by arranging the support rod 12 and the pin shaft. The protective cover can prevent dust and impurities from being mixed into the synchronous belt 605 during stamping and causing wear; grooves are opened on the two side surfaces of the mounting plate 5, and the inner wall of the groove is rotatably connected with a gear 603. The gear 603 is rotatably connected with the ratchet disk 602 inside the synchronous belt 605 through a rotating shaft.

When the punching head 3 rises, it drives the telescopic mechanism 4 to move upward, the telescopic mechanism 4 drives the mounting plate 5, the mounting plate 5 drives the synchronous belt 605, and the synchronous belt 605 drives the workpiece to move upward. When the telescopic mechanism 4 moves upward to the position of the upper fixed plate 8, the baffle 11 is used to stop the telescopic rod 402 from moving upward, while the guide cylinder 401 continues to move upward, the guide cylinder 401 drives the rack 604 to move upward, and the rack 604 drives the gear rack 604 to move upward. The wheel 603 rotates, and the gear 603 drives the ratchet disc 602 in the synchronous belt 605 to rotate.
