In this way, the damaged polishing wheel 13 can be quickly removed from the machine for replacement. When installing, first align the end of an assembly rod 5 with the plug 6 with the installation shaft 4 and insert it. At the same time, insert the corresponding plug 6 into the socket 7 on the installation shaft 4. During this period, the card block 9 on the plug 6 will also be inserted into the corresponding card slot 8. At the same time, the spring piece 15 will also be stuck in the corresponding positioning groove 16, thereby fixing the installation shaft 4 and the assembly rod 5. In this way, the installation shaft 4 and the assembly rod 5 will not move at will, wherein the spring piece 15 is installed in the card slot 8, and the positioning groove 16 is open The spring piece 15 is provided on the card block 9 and is clamped in the positioning groove 16. During assembly, the plug 6 is inserted into the corresponding jack 7, and the card block 9 is also inserted into the card slot 8. Finally, the spring piece 15 is clamped in the corresponding positioning groove 16. In this way, the plug 6 and the corresponding assembly rod 5 can be positioned, and the positioning of the polishing wheel 13 can be completed, thereby improving the power and convenience for subsequent installation work, and facilitating the user to quickly complete the assembly of the polishing wheel 13. Then, after the current assembly rod 5 is installed, the new polishing wheel 13 is immediately sleeved on the assembly rod 5, wherein the corresponding plug 6 will also be inserted into the corresponding jack 7, the corresponding card block 9 will also be inserted into the corresponding card slot 8, and the corresponding spring piece 15 will also be clamped into the corresponding The positioning groove 16 realizes the positioning and fixing of the assembly rod 5 and the polishing wheel 13. It should be noted that the subsequent installation of the assembly rod 5 and the polishing wheel 13 is also installed according to the above process. After the polishing wheel 13 is sleeved on the assembly rod 5, the assembly rod 5 and the limiting clamping strip 12 are both inserted into the adapting hole 14 on the polishing wheel 13 to realize further positioning and fixing of the polishing wheel 13. The assembly rod 5 and the limiting clamping strip 12 are adapted to the adapting hole 14.
