Abstract

The utility model provides a brush fixing device. The brush fixing device comprises a brush grip cover and a brush grip; the brush is disposed in the brush grip; two opposite sides on the brush grip cover are provided with lock pieces; two opposite sides on the brush grip are provided with lock grooves which match the lock pieces; the lock pieces are embedded into the lock grooves and buckles are formed; the brush grip cover is fixedly disposed at one end of the brush grip through the buckles. According to the brush fixing device, since the buckles are formed by the mutually cooperated lock pieces and lock grooves on the brush grip cover and the brush grip, the brush grip cover can only be clamped and fastened from the one end of the grip cover, and plays a role in firmly and radially checking the brush, and thus a problem that assembly between the brush and the brush fixing device is difficult is solved, and a phenomenon that ejection of the brush grip cover during a work process of the brush is prevented.
