Wall surface polishing device capable of polishing internal corners

Abstract

The invention relates to the technical field of house decoration, and discloses a wall surface polishing device capable of polishing internal corners. A fan is included. A first limiting block is arranged above the fan, the left side of the first limiting block is fixed connected with a screw, an adjusting nut is connected to the outside of the screw in a sleeving mode, a sliding block is movablyconnected to the left side of the adjusting nut, a second limiting block is fixedly connected to the left side of the screw, a spring is fixedly connected to the right side of the second limiting block, a fixed block is arranged on the left side of the second limiting block, and two second connecting rods are rotatably connected to the top of the fixed block, and the opposites sides of the two second connecting rods are rotatably connected with two internal corner polishing plates. By the internal corner polishing plates, when the internal corners need to be polished, the adjusting nut slidesto the left to drive the sliding block to move to the left until the sliding block is in contact the second limiting block, and the internal corner polishing plates extend, so that the effects that when the internal corners are polished, tools are not required to be changed additionally, and work efficiency is improved are achieved.

Description
