[0030] Finally, the staff takes out the fixing nut 4 and rotates the fixing nut 4 to the rear end of the mounting rod 1 by using a wrench, so that the fixing nut 4 is pressed against the surface of the grinding wheel 2 to fix the grinding wheel 2, thereby ensuring the stability of the grinding wheel 2 installed on the surface of the mounting rod 1.

[0031] Working principle: After the staff takes out the grinding wheel 2 and sleeves the grinding wheel 2 on the rear end of the mounting rod 1, the staff can rotate the bolt 10 by using a wrench, and the rotation of the bolt 10 drives the spherical ball 11 to move backward to press the inner wall of the triangular chute 9, thereby driving the fixing block 7 to gradually slide to the left and be clamped into the inside of the fixing slot 8 for installation and fixation. In the process of sliding on the surface of the guide rod 12, the fixing block 7 can press the sleeve spring 15, and the sleeve spring 15 provides a reverse elastic force to the fixing block 7. When it is necessary to disassemble the grinding wheel 2, the staff only needs to rotate the bolt 10 in the reverse direction by using a wrench, and the rotation of the bolt 10 drives the spherical ball 11 to move forward to disengage from the inner wall of the triangular chute 9. At this time, the sleeve spring 15 releases the elastic force and pushes the fixing block 7 to slide reversely to disengage from the inside of the fixing slot 8, thereby releasing the fixing effect on the grinding wheel 2. Since the fixing block 7 and the grinding wheel 2 are in direct contact, when the grinding wheel 2 moves to press the surface of the fixing block 7, the fixing block 7 will not move. Finally, the staff takes out the fixing nut 4 and rotates the fixing nut 4 to the rear end of the mounting rod 1 by using a wrench, so that the fixing nut 4 is pressed against the surface of the grinding wheel 2 to fix the grinding wheel 2.

[0032] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
