However, it is not suitable for the production of gaskets required for on-site debugging after the fixture is put into use. The amount of on-site debugging is not large. They are all marked first, then drilled on a drill press and sheared. Burrs need to be ground off, and the drilling machine equipment is fixed. The thin steel plate used to make the gasket is not easy to tighten on a small drill press. There are certain safety hazards and low efficiency, which is not conducive to the normal production. If each gasket is made in advance, it will increase the company's costs and increase inventory waste.

[0004] Therefore, a puncher is provided to address the deficiencies in the prior art. Utility Model Content
