[0002] The wall polisher can also be called a wall polisher, a wall sanding machine, a wall polisher, a putty polisher or a polishing machine. It is called differently in different places. When polishing the wall, the wall polisher is needed.

[0003] At present, in the decoration process, the wall needs to be polished by using the polisher, and the general polisher is provided with a protective cover, so as to facilitate the collection of polishing dust and prevent the polishing dust from splashing. However, the general protective cover is generally fixedly arranged, which is not convenient for adjusting the front and back positions of the protective cover, and the protective cover is easy to be abraded with the wall, thereby reducing the polishing uniformity. Therefore, we design a building wall polisher to facilitate the adjustment of the position of the protective cover. UTILITY MODEL CONTENT
