Brushes with different materials and structures are suitable for different occasions and requirements. For example, soft brushes are suitable for cleaning precision instruments and sensitive surfaces, while hard brushes are more suitable for removing stubborn stains or treating rough surfaces. In industrial production, automated brush equipment can efficiently complete operations such as large-area painting, deburring, and polishing, improving production efficiency and product quality.

[0003] A Chinese patent with the publication number CN210930115U discloses a brush, which includes a hollow handle and a brush part. The bristles used in the brush part are imitation animal hairs. The brush part includes a fixed part and a fastening part that is fastened to the fixed part. The fixed part is integrally formed with the handle. The imitation animal hairs are pasted on the upper surface of the fastening part through glue. The fixed part is a hollow structure, and a plurality of fixing blocks for supporting and balancing the surface of the fastening part are arranged in the cavity of the fixed part. The fixing blocks are movably connected to the fixed part. An extension part is provided at the end of the handle, and the extension part is detachably connected to the handle.

[0004] Although the above scheme can effectively clean dust and better protect the material from being scratched, the overall structure of the brush is fixed, and the handle cannot be folded, resulting in a relatively long overall length during storage, which is not easy to store and affects carrying. Therefore, it does not meet the existing needs, and for this reason, we propose a brush with a folding handle effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a brush with a folding handle effect to solve the problem that the brush handle cannot be folded, resulting in a relatively long overall length and not being easy to store as mentioned in the above background art.
