A combination buckle 505 is fixedly installed on the output end of the motor 508. The connecting shaft 504 and the combination buckle 505 are slidably connected. When the laser cutting head 4 needs to be cleaned, the laser cutting head 4 is moved Go into the cleaning chamber 503 and start the motor 508. The motor 508 drives the cleaning chamber 503 to rotate. The cleaning brush 509 rotates with the cleaning chamber 503 to quickly clean the laser cutting head 4 and remove metal particles and other impurities on the surface. The cleaning chamber 503 can be disassembled through the combination connection of the connecting shaft 504 and the combination buckle 505 to remove the metal particles and impurities that fall after the internal cleaning is completed. A magnetic attraction layer 502 is slidably connected between the circumferential inner wall of the outer chamber 501 and the circumferential outer wall of the cleaning chamber 503. During the cleaning process, the magnetism of the magnetic attraction layer 502 is transferred to the wall of the cleaning chamber 503. After the cleaning brush 509 cleans away the metal particles, it is adsorbed to prevent them from sticking to the laser cutting head 4 again. The combination buckle 505 and the circumferential outer wall of the connecting shaft 504 are slidably connected with a fixing bolt 506, and one end of the fixing bolt 506 is threadedly connected with a fixing sleeve 507. In order to ensure the firm connection between the motor 508 and the cleaning chamber 503, the combination buckle 505 and the connecting shaft 504 are stably connected through the combination of the fixing bolt 506 and the fixing sleeve 507.
