[0002] In the field of modern mechanical processing, wire cutting machines are widely used in cutting various materials due to their high precision and high efficiency. The working principle of wire cutting machines is mainly to generate discharge sparks through the high-speed movement of the electrode wire between the workpiece and the guide wheel to erode the material, thereby achieving cutting of the workpiece.

[0003] However, most of the existing guide wheel anti-falling structures are clamped and fixed with anti-falling clips, which are troublesome to install and usually lack stability. They are prone to falling due to their own instability, and cannot play a protective role. There are safety hazards. We propose a guide wheel anti-falling structure. Utility Model Content
