[0008] Compared with the prior art, the utility model has the following beneficial effects: the operator installs the grinding wheel body onto the driving device through the cooperation of the fixing sleeve and the threaded groove; the super-hard grinding layer can improve the grinding effect during grinding, and the dust generated during grinding will enter the first ash inlet hole and the second ash inlet hole through the first annular groove and the second annular groove, and at the same time, the dust will enter the third ash inlet hole through the ash collecting groove, and the dust entering the first ash inlet hole, the second ash inlet hole and the third ash inlet hole will enter the dust collecting plate for collection, thereby greatly reducing the flying of dust;

[0009] When there is a lot of dust inside the dust collecting plate, the operator rotates the fixing ring, and the fixing ring drives the sealing plate to rotate through the fixing connecting rod and the fixing connecting head. When the sealing plate rotates, it drives the blocking bolt to rotate out of the threaded hole, so that all the dust can be poured out. This makes the grinding wheel less dusty during grinding, ensures the operator's operating vision and health, and has a very good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
