Description

Technical Field

[0001] The utility model relates to the technical field related to roller brushes, in particular to an easily adjustable roller brush handle component. 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] During painting operations, it is often necessary to paint work surfaces of different heights. However, due to the length limit of the roller brush handle, when the painting work surface becomes higher, the user generally paints on tiptoe or with the help of scaffolding or other elevated platforms. Long-term tiptoe painting operations will cause the painters to feel tired. When painting operations are carried out with the help of scaffolding or other elevated platforms, there are safety hazards and the risk of slipping. In addition, the replacement operation between the roller brush and the handle is difficult. In this regard, the present invention specially proposes an easily adjustable roller brush handle assembly to solve the above problems. Utility Model Content
