Abstract

The invention relates to the technical field of electric tools, in particular to a wall polisher. The wall polisher comprises an operating handle, a motor and a polishing head. The polishing head comprises a top cover, a base and abrasive disc assemblies. A transmission mechanism for transmitting the torque of the motor to the abrasive disc assemblies is arranged between the top cover and the base. An output shaft of the transmission mechanism is an eccentric shaft or a concentric shaft. An abrasive disc of each abrasive disc assembly is installed at the lower end of the eccentric shaft or the concentric shaft. The base is internally provided with a rotating disk, one side of the rotating disk is provided with a shifting handle, the rotating disk is provided with one or more limiting holes, the top cover is fixedly provided with a positioning rod stretching into the limiting holes, and the limiting holes can clamp or loosen the positioning rod through the rotation of the rotating disk. According to the wall polisher, the two different abrasive disk assemblies are usually prepared, the output shaft of the transmission mechanism of one abrasive disk is the eccentric shaft, the other output shaft of the transmission mechanism of the other abrasive disk is the concentric shaft, different abrasive disk assemblies can be rapidly switched, and therefore the wall corner can be polished very conveniently.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a wall grinder. Background technique [0002] Wall sanders are a well-established technology for sanding and cleaning walls before they are painted, painted or wallpapered. [0003] In the prior art, the wall grinding machine has the following defects: (1) the grinding head of the wall grinding machine generally adopts a circular grinding disc, however, the circular grinding disc is not suitable for grinding the corners of the wall; In the case of different surface materials, the adsorption force of the wall grinder cannot be adjusted. Contents of the invention [0004] The purpose of the present invention is to provide a wall grinding machine capable of grinding the corners of the wall better and quickly replacing the grinding head. [0005] The purpose of the present invention is achieved like this: [0006] The wall grinder includes an operating handle, a motor, an...
