Abstract
The invention discloses a brush holder, comprising a brush carrier, a fixed base, a locking mechanism, a locking cap, and a torsion mechanism. The brush carrier is fixed under the fixed base. The locking mechanism is fixed on the fixed base. An end of the locking mechanism extends into the torsion mechanism and is connected with the torsion mechanism. The other end of the locking mechanism is detachably connected with the locking cap. When a brush needs changing, the brush is pressed downwards and meanwhile the torsion mechanism of the brush holder is rotated by an angle of 90 DEG towards any direction. Thus, the torsion mechanism drives the connected locking mechanism to rotate 90 DEG, and the locking mechanism is connected or disconnected with the locking cap which is fixed on a motor installation mechanism in advance, so that the brush holder is integrally installed on the motor or taken off from the motor, and operation of changing the brush is completed further. Operation of loosening and screwing up brush braid fixing bolts in the prior art is not needed, so that process of changing the brush is simplified and security of changing operation is improved.
