[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting an adjustment component, can push the fixed plate to move when the electric push rod two is turned on. The movement of the fixed plate causes the strip box and the punching part on the lower side to move longitudinally. At the same time, the motor one can drive the drive roller to drive the conveyor belt to run in the strip box. The conveyor belt can drive the electric push rod one at the lower end of the connecting plate and the punching part to move laterally through the I-shaped block. The I-shaped block slides in the slide groove two at the lower end of the strip box. By setting the adjustment component, the position of the punching part can be moved and adjusted, which is convenient for punching holes in different positions of synthetic leather and improving the working range of the punching part.
[0013] 2. This utility model, by setting up a holding component, allows the synthetic leather to be laid flat on the worktable. The motor is then turned on to drive the screw to rotate. The rotation of the screw causes the slide to move downwards. The slide causes the folding rod to slide on the upper end of the fixed frame. The downward movement of the folding rod uses the pressure plate to hold and fix the two ends of the synthetic leather on the worktable. By setting up the holding component, the fixing effect of the synthetic leather to be punched is better, and the synthetic leather is less likely to shift when punching holes.
