[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention places the sheet material in the middle area of the frame slot of the bracket. At this time, the cylinder is running, driving the transmission rod to move downward, so that the punching head moves downward to punch and punch the material. The two punching heads are respectively fixed on the two assembly seats. The two assembly seats are movably connected to the connecting seat through a slide, which is used to move the assembly seat and the punching head. The position of the punching head is changed to change the spacing of the punching holes during punching to meet the needs of punching holes with different spacings. After adjusting the position, tighten the positioning screw and limit the slide after adjusting the position;

[0016] 2. The screw hole at the bottom of the transmission rod is used to pass the screw. When the screw is tightened, the transmission rod and the connecting seat are fixed together. When the screw is loosened, the connecting seat can be rotated relative to the transmission rod, changing the direction of the connecting seat, so that the two punching heads can switch positions. At this time, the punching head can be tilted relative to the placed sheet material. Then, during the stamping process, the sheet material can be punched obliquely.
