[0002] A prism is a transparent object surrounded by two intersecting but non-parallel planes, used to split or disperse light beams. A prism is a polyhedron made of transparent material, which is widely used in optical instruments. Prisms can be divided into several types according to their properties and uses. The shape of a prism is changed by drilling and polishing, but the existing prism punching device does not have a protective mechanism, and is unable to block the waste generated when the prism is punched, causing the waste to fly into the eyes of the staff, resulting in poor safety. In addition, the punching position cannot be fixed during punching, which may cause the prism position to shift and the punching accuracy to be poor. Utility Model Content
