[0002] The carbon brush, also known as the brush, as a sliding contact part, is widely used in many electrical devices. The main materials for carbon brushes in product applications are graphite, impregnated graphite, metal, and graphite. The carbon brush is a device for transmitting energy or signals between the fixed part and the rotating part of a motor, generator, or other rotating machinery. It is generally made of pure carbon plus a solidifying agent, and its shape is generally square. It is stuck in a metal bracket, and there is a spring inside to tightly press it against the rotating shaft. When the motor rotates, electrical energy is transmitted to the coil through the commutator. Since its main component is carbon, it is called a carbon brush. It is easily worn and should be maintained and replaced regularly, and the carbon deposits should be cleaned. The carbon brush looks a bit like an eraser for erasing pencils, with a wire led out on the top, and its volume varies. As a sliding contact part, the carbon brush is widely used in many electrical devices. The main product materials are electrographite, impregnated graphite, metal, and graphite. The carbon brush fixing bracket can play a good protective role during the use of the carbon brush and can effectively ensure the extension of the service life of the carbon brush.

[0003] When the existing device is in use, the main body of the carbon brush fixing bracket cannot be adjusted in angle, and it is easily affected by external collisions during use, resulting in a reduced service life. It cannot provide a buffering force for the internal carbon brush, and it cannot be disassembled and repaired, making the later maintenance cumbersome.

[0004] Therefore, in view of the above problems, a motor carbon brush fixing bracket for preventing carbon brushes from falling off is proposed. Content of the Utility Model
