Description

Technical Field

[0001] The utility model relates to the technical field of wall grinding, in particular to a portable wall grinding machine for decoration. Background Art

[0002] When decorating indoors, the wall needs to be decorated. Before painting or pasting wallpaper, the wall needs to be polished and cleaned. Wall polishers are widely used due to their high polishing efficiency and ease of use. The existing wall polisher has a head equipped with a drive motor, a reducer and a working disc. The drive motor drives the working disc to rotate through the reducer, and the sandpaper on the working disc polishes the wall, thereby making the wall smooth.
