[0002] Telescopic machine tool protective cover is one of the common accessories in machine tools. It is mainly used to protect machine tool guide rails, screw rods and other components to prevent iron chips from falling onto the guide rails or screw rods and hindering their operation. Telescopic machine tool protective cover is usually composed of multiple cover bodies, which are slidably connected to each other, and the cover bodies at both ends are fixed to the machine tool by bolts.

[0003] According to the application number: CN202322719381.6, a retractable machine tool protective cover is disclosed, which includes a main cover shell, a side positioning plate is welded on one side of the main cover shell, a first telescopic section is provided inside the other side of the main cover shell, and a structure for facilitating telescopic assembly and disassembly is provided between the top ends of the main cover shell, the first telescopic section, the second telescopic section, and the third telescopic section. The retractable machine tool protective cover is provided with a first positioning guide rod, a concave fixing plate, a second positioning guide rod, an anti-slip nut, and a guide rod perforation. When in use, the concave fixing plate inside the telescopic section is displaced along the corresponding first positioning guide rod and the second positioning guide rod. The guide rod perforation facilitates the passage of the guide rod, and the anti-slip nut limits the displacement distance. When disassembly, assembly, maintenance, and replacement are required, only four sets of anti-slip nuts need to be loosened to complete the disassembly, assembly, and replacement, thereby realizing the function of being easy to retract, disassemble, and maintain, and solving the problem that the device does not have the function of being easy to retract, disassemble, and maintain.

[0004] Based on the above, the existing retractable machine tool protective cover is easily deformed and damaged when it is hit during use. In order to ensure the normal use of the protective cover, the protective cover needs to be replaced. Since the protective cover is usually fixed by bolts, multiple bolts need to be removed during replacement, which is cumbersome and affects work efficiency. Utility Model Content
