In addition, the protection effect of the existing aluminum veneer grinding device is poor, and the grinding sheets are exposed to the outside. When in use, the operator is prone to accidentally touch the high-speed rotating blade. In this solution, in the initial state, the spring 7 will always push the sliding ring 5 to the side of the No. 2 fixing ring 3, so that the sliding ring 5 is tightly attached to the side of the No. 2 fixing ring 3, thereby keeping the sliding sleeve 6 always on the outside of the grinding disc 8.
