[0002] With the development of technology, laser drilling machines are also constantly updated and developed. During the operation of laser drilling machines, different products need to select different jigs for production. In the prior art, during laser drilling processing, the operator needs to use tape to seal the jig and fix it on the processing platform. When replacing the jig, you need to first tear off the tape and remove the old jig, then replace it with a new jig, and then connect the new jig to the processing platform with tape. However, due to the limited operating space of the processing platform and the relatively smooth surface, the tape is difficult to stick and tear off, and the process is relatively cumbersome, affecting the efficiency of jig replacement. In addition, after laser drilling processing, waste will accumulate on the platform, blocking the laser light path and resulting in defective products. Utility Model Content
