[0002] The elbow roller brush is a professional tool for decoration. It is mostly made of engineering plastics and fibers, and some are made of natural wool fabrics.

[0003] For example, the Chinese patent with application number CN201821853532.X discloses a novel roller brush adjustment mechanism, which is installed on the roller brush installation side of the machine body. The roller brush is a cylindrical cylinder with bristles attached to the surface, including a roller brush bracket, a pin shaft, a telescopic spring and a tooth box. Mounting holes are provided at the axial positions of both ends of the roller brush, and an axial hole is provided at the center bottom of the mounting hole. The roller brush bracket is gyroscope-shaped, and the middle part is a circular plate. A hollow cylindrical barrel cavity connected to the center of the circular plate surface is provided, and one end of the barrel cavity cooperates with the mounting hole. One side surface of the circular plate is in contact with the end of the roller brush, and a partition with a central opening is provided in the barrel cavity on one side of the circular plate surface. The pin shaft is vertically installed on the barrel cavity partition of the roller brush bracket.

[0004] However, the above solution has the following disadvantages: when it is used, it can prevent the roller brush from swinging left and right and generating noise, but it lacks the multi-angle use of the roller brush and the height adjustment of the roller brush.
