Description

Technical Field

[0001] The utility model relates to the technical field related to roller brushes, and in particular to a roller brush which is convenient for adjusting the overall length. Background Art

[0002] A roller brush is a tool for rolling paint on a large area. It is used frequently in daily architectural decoration projects when rolling paint on a large area. The roller brush handle is an important component of the roller brush. When using the roller brush, the roller brush is generally placed in a paint bucket and dipped in paint. After the roller brush is taken out of the paint bucket, more paint is dipped on the roller and the surface to be painted is painted.

[0003] A roller brush, also known as a roller, is divided into three types: long-hair, medium-hair, and short-hair. It is a tool used for rolling paint on a large area. During construction, the exterior walls of a house built with bricks need to be painted. Putty powder will be applied on the exterior walls before paint is applied on the exterior walls, making the exterior walls more beautiful and more durable. Existing roller brushes often need to be installed before use. Since the installation of the device is more cumbersome, the installation time of the device is increased. At the same time, the device has a single structure and a fixed length, which reduces the diversity and applicability of the device. In this regard, this solution specifically proposes a roller brush that is easy to adjust the overall length to solve the above problems. Utility Model Content
