At this time, the disassembly frame 2 can be moved out of the workbench 1, and then the handle 15 is pulled. The handle 15 will drive the protective shell 14 to move, so that the protective shell 14 is separated from the cutting wheel 13, and the cutting wheel 13 is moved to separate from the spline shaft 12. At this time, the cutting wheel 13 can be detached, which is convenient for the staff to inspect or replace it, thereby improving the service life of the device.
