[0002] Machine tool protective cover is used to protect machine tools. It can protect the surface of machine tools from external corrosion and damage. There are many types. There are: accordion protective cover, steel plate protective cover, these two are used on the guide rail. There are also screw protective covers used on the screw, including: round, square, polygonal. These types of methods are different. There are wire support type and stitching type. There are also roller shutter protective covers and armor protective covers;

[0003] For example, the protective structure of a CNC cylindrical grinder disclosed in the utility model with authorization announcement number CN213616094U combines a hard mechanical cover with an accordion-type guide rail mesh cover. The hard mechanical cover is used to protect the mechanical outer wall of the equipment, and the accordion-type guide rail mesh cover protects the outside of the guide rail and other components to meet the protection requirements of different structures of the grinder. However, when installing the accordion cover, it is necessary to connect the arc-shaped support rods on the accordion cover with the connecting rods with the help of support sleeves and other components while opening the accordion cover, so that the accordion cover can be installed on the cylindrical grinder. This makes the installation process of the accordion cover more complicated and inconvenient for the quick installation and protection of the exposed part of the cylindrical grinder by the accordion cover.
