The box 43 is slidably connected in the dust collecting groove 42, the front dust suction pipe 48 is located above the grinding disc 2, the side air duct 45 is fixedly installed on the surface of the wind groove 44 on the left and right sides, the extension pipe 46 is fixedly installed on the end of the side air duct 45 away from the wind groove 44, and the trumpet dust suction port 47 is located on both sides of the grinding disc 2 near the bottom position. When the wall is polished during decoration, the friction between the grinding disc 2 and the wall produces a large amount of dust. Turn on the vacuum cleaner 41 to make the wind groove 44 suck air inward, and the dust enters the vacuum cleaner 41 through the front dust suction pipe 48 and the trumpet dust suction ports 47 on both sides, and falls into the dust collecting box 43 in the dust collecting groove 42. After use, the dust collecting box 43 is pulled out of the dust collecting groove 42 for cleaning.
