Moreover, the inner diameter of the air suction port can be 2.00 mm, which matches the aperture of the largest punching hole 221 on the punching pin punching module 220. The air suction port is connected with the waste collection container 320 through the collection pipe 310, and the tail end of the collection pipe 310 is connected with the waste collection container 320. A red scale line is attached to the position of 80% of the volume of the waste collection container 320, so that when the punching waste collected reaches the red scale line, the punching waste in the waste collection container 320 needs to be removed in time to prevent too much waste from affecting the collection effect and causing surface waste residue. In addition, the above-mentioned negative pressure generating device can be an air extractor.
