Embodiment Construction
[0008] The present invention consists of a brush roller body (1), 2. an elbow assembly (2), a handle (3), and an extension rod (4). Both the handle and the extension rod are hollow, and the inner wall of the handle is processed with internal threads. The extension rod is divided into two parts. One end of the extension rod is designed with external threads, and the other end is designed with internal and external threads. , the two extension rods can also be fixedly connected through the internal thread at one end and the external thread at the other end. They can be used in combination according to the needs of the actual situation, and can also be used separately without the extension rod.

The invention discloses a roller brush with lengthened rods. The roller brush with the lengthened rod is composed of a brush roller body, a bend pipe assembly, a handle and the lengthened rods. The handle and the two lengthened rods are hollow; an inner thread is machined on the inner wall of the handle; one end of each lengthened rod is provided with an outer thread; the other end of each lengthened rod is provided with inner and outer threads; the lengthened rods are rotationally and fixedly connected with the inner thread of the handle through the outer threads on one ends; the two lengthened rods can be rotationally and fixedly connected through the inner thread at one end and the outer thread at the other end; assembly and disassembly are convenient, the structure is simple, and the lengthened rods are combined for use according to actual conditions and can also be disassembled for independent use. When the roller brush is used for painting a square house, as the position above a wall or a ceiling is tool high, the brush can not reach the painted position, a ladder or other climbing tool is needed, inconvenience is brought, and at this time, a user hopes that the roller brush in hands can be lengthened so that the brush can reach the high position easily.
Description
technical field [0001] The invention belongs to a roller brush, in particular to a roller brush with an extension rod. technical background [0002] When we paint the interior walls, the top of the wall and the ceiling often need to use tools such as ladders due to insufficient height, which is very inconvenient. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and to provide a roller brush with a simple structure and technology and an extension rod. [0004] The technical method adopted by the present invention to solve the technical problem is: a roller brush, which is composed of a brush roller body, a curved pipe assembly, a handle, and an extension rod. It is characterized in that: the handle and the extension rod are hollow, and the inner wall of the handle is processed Thread, the extension rod is divided into two parts, one end of the extension rod is desig...
