[0004] The above-mentioned technical scheme has certain beneficial effects, but in actual use, since the two sides of the workpiece are clamped and fixed between the bottom plate of the positioning fixture and the upper plate of the positioning fixture, it can prevent up and down movement. However, the force of the engraving and milling machine is relatively large during processing. Although the transverse spring telescopic rod can be adjusted, it cannot resist the force caused by the engraving and milling machine during processing, which makes it easy for the workpiece to move laterally, resulting in the engraving and milling machine being unable to stably engrave the workpiece. For this reason, we propose a positioning mechanism for engraving and milling machine processing. Utility Model Content
