Flatness control structure for a drywall sander

Abstract

A flatness control structure for a drywall sander, comprising: a device body, wherein the bottom of the device body is equipped with a rotating device, a housing is arranged below the device body, a sanding component is arranged inside the housing, the sanding component comprises a sanding piece, the bottom of sanding piece is connected to a sanding disc, and the bottom of sanding disc is connected to sandpaper, a threaded bolt is arranged between the sanding piece and the housing, a fixing component is arranged inside the housing, and an installation component is arranged inside the housing. The sander replaces the bristle sections with a wear-resistant strip which is less likely to deform when in contact with the sanding surface. When force is applied, the sander can be firmly fixed on the sanding surface, ensuring stability of the entire sander, thereby improving the flatness of the sanding surface.
