Wall space sander

The utility model discloses a wall space sander, and solves the technical problems of enabling the wall space sander to be convenient to use, high in construction efficiency, meticulous in polishing, consistent in scratch and good in impressions. To solve the technical problems, the technical scheme includes that the wall space sander is a circular shape formed by a manner that two ends of bent saw blade are fixedly connected and are enclosed . One side of the bent saw blade is a sawtooth part, and the other side of the bent saw blade is a saw blade back. The wall space sander is the circular shape formed by enclosing the bent saw blade, is provided with two faces used for polishing, and can be matched with floated coat wall space with different thicknesses. Compared with an existing construction technology, the wall space sander is high in efficiency, can be matched with mechanized construction to be used, and can be well adapted to air shrinkage efficiency of motor. Immediate construction is not needed. Aft
