[0032] The transverse movement mechanism includes a transverse movement seat 230, which is arranged on the top of the punching component, and the transverse movement seat 230 is arranged on the bottom of the lifting seat 220 for sliding transversely; the transverse movement seat 230 can be moved to adjust the position of the punching component in the transverse direction; the friction between the transverse movement seat 230 and the lifting seat 220 can be set to an appropriate size, so that the transverse movement seat 230 can be locked in the current position by friction; of course, a screw can also be set to lock the transverse position of the transverse movement seat 230, that is, the transverse movement mechanism also includes a screw, which is arranged transversely, and the screw is rotatably arranged on the lifting seat 220, and the screw is threadedly connected to the transverse movement seat 230. The transverse position of the transverse movement seat 230 can be adjusted by rotating the screw, thereby adjusting the transverse position of the punching component. One end of the screw protrudes from the lifting seat 220 and is provided with a handwheel or other mechanism that can rotate the screw to facilitate the rotation of the screw.
