Abstract: A novel glue-free makeup brush with a clamping assembly, including a handle, a brush head, and a connecting piece. The brush head includes bristles and a mounting piece, and is arranged on an upper end of the handle. The bristles are arranged on the mounting piece, and the mounting piece is clamped with the connecting piece. An upper end of the clamping assembly, formed by a first clamp and a second clamp, is provided with a groove, in which the mounting piece is arranged. In this way, the brush head can be arranged on the clamping assembly without using glue. The handle is removably connected with a sleeve of the connecting piece.
