[0009] Through the above technical solutions: When in use, pulling the limit plate can stretch the limit spring. At this time, the limit rod slides along the inner wall of the limit opening into the limit groove, and then the connection block is separated from the inner wall of the connection groove, enabling the brush shell to be separated from the connection plate. At this time, the bristles and the brush shell can be replaced. When installing the brush shell, insert the connection block fixedly connected to the brush shell into the connection groove. After the limit opening is aligned with the limit groove, the limit rod slides into the limit opening under the pulling force of the limit spring, fixing the brush shell. When painting, the excess paint can flow into the cavity through the paint baffle, preventing the paint from dripping or flowing onto the hands of the operator. The rotating roller can smooth the paint. The operator can tilt their hand to make the rotating roller contact the wall. It is also possible to replace the rotating roller with a patterned one to apply patterns to the paint. When encountering a narrow space or when it is inconvenient to construct with the hands, the handle can be rotated. At this time, the threaded rod rotates in the inner wall of the threaded groove, adjusting the position of the handle for convenient painting operation. Therefore, it is convenient and flexible to change the painting method, significantly improving the painting efficiency.
