Abstract: The present invention relates to a brake, which has a fixed seat, a friction brake shoe, a braking part, a braking spring, an acting block, and a driving block. The acting block is connected with a driving member and matched on an acting face of the driving block. The driving block is connected with the braking part. The braking spring has a first end connected with a driven member and a second end connected to the braking part. The braking part is articulated on the driven member by a support pin. The braking part can be engaged with the friction brake shoe or disengaged from the friction brake shoe, and connected with a driven member. In a normal operation or still state, the brake is capable of braking or releasing braking without additional power.
