Three hinge seats 37 are arranged on the collar rings 36, a connecting rod 35 is hinged on the hinge seats 37, and the end of the connecting rod is rotatably connected to a strip-shaped groove inside the fixing plate 33. The fixing plate 33 is of a "C" - shaped structure. The gear 11 to be polished is arranged outside the fixing component 3. The sleeve 32, the main gear 210 and the elastic column 26 are coaxially arranged. The collar ring 36 of the activity column 31 is fixedly arranged at the upper part, and the collar rings 36 of the sleeve 32 are fixedly arranged at the bottom and the middle. An arc plate 34 is arranged outside the fixing plate 33.

After the rotating rod 23 passes through the connecting shell 24 and the upper planet carrier 28 through bearings, a main gear 210 is provided. Three driven gears 211 are meshed outside the main gear 210. The driven gears 211 are fixed to the upper planet carrier 28 through rotating shafts. The upper planet carrier 28 is fixedly connected to the connecting shell 24. A gear ring 29 is meshed outside the driven gears 211, a grinding sheet 25 is fixed outside the gear ring 29, the connecting shell 24 is fixedly connected to the grinding sheet 25. A lower planet carrier 27 is arranged below the driven gears 211, the lower planet carrier 27 is fixed to the upper planet carrier 28 by a fixing rod.
