[0002] In the process of machining workpieces using CNC lathes, in order to prevent the debris generated during the machining process from flying randomly, and to prevent the user from accidentally approaching the machining structure and causing danger, a protective structure is usually set on the machining table. Although the existing CNC lathe protection mechanism can meet the basic isolation protection function, the protective structure is often slidably set on the top of the machining table, and the inner wall of the protective structure is often facing downward. When the user needs to clean the inner wall of the protective structure, it will be very troublesome, time-consuming and laborious, which will bring great inconvenience to people's use.

[0003] For example, the utility model with announcement number CN 210334378 U discloses a new protective cover for a CNC lathe. In the technical solution of this patent, the protective cover is slidably arranged on a workbench and a shell. Since the inner walls of the shell and the protective cover are always facing downward, it is not convenient to make the inner walls of the shell and the protective cover face upward. Therefore, when the inner walls of the shell and the protective cover need to be cleaned, they can only be inserted into the inside of the shell and the protective cover for cleaning, which will bring great inconvenience to people's use.
