[0002] After placing the workpiece flat on the work platform of the laser marking machine, the laser marking machine can be used to engrave text on the workpiece surface. The traditional method of positioning the workpiece involves setting mutually perpendicular stops in two directions on the work platform. However, this generates harmful fumes during laser engraving, which are harmful if they diffuse into the air or are inhaled by the operator, resulting in poor overall performance. Therefore, this invention proposes an engraving fixture for a laser marking machine. Utility Model Content
