An air hole 34 is provided on the fixing plate 3. An external air pipe connector 35 is fixed on the back of the fixing plate 3 and at a position corresponding to the air hole 34. An external shaft connector 32 is fixed on the back of the fixing plate 3 and at a position corresponding to the connecting shaft 31. A guide groove 43 is provided on the outer wall of the slide bar 41. A guide block 42 matched with the guide groove 43 is provided on the inner wall of the adjusting block 4. A heat dissipation groove 21 is provided on the periphery of the grinding disc body 2. An exhaust groove 22 is provided on the rear side of the grinding disc body 2. The fixing plate 3 protrudes outward and a cavity is provided between the fixing plate 3 and the grinding disc body 2.
