[0012] 1. The utility model sets one of the axes of the grinding roller to be composed of a transition shaft, a waist groove piece, a bayonet pin and a secondary shaft, and then sets a slip ring elastically supported by a spring on the inner side of the roller body of the grinding roller. When the square key shaft at the other end of the grinding roller is separated from the motor, the roller body is pushed to make the roller body and the secondary shaft slide relative to each other, and at the same time, the bayonet pin on the waist groove piece is separated from the roller body, and then the roller body can be disassembled by rotating it ninety degrees, which is more convenient.

[0013] 2. The utility model sets a fixing sleeve, a locking pin, a lever, a spring and other components at the end of the roller body. The locking pin is inserted into the bayonet pin under the elastic force of the spring, so that the bayonet pin, the waist groove piece, the transition shaft and the auxiliary shaft and other components can be locked, thereby ensuring the stability of the connection between these components and the roller body.
