Provided is a hand brake, comprising a hand wheel (4), a chain (5), an enclosure (1), a drive shaft assembly (3) which is disposed in the enclosure (1), bull gear (13), and base assembly; the hand wheel (4) is connected to the drive shaft assembly (3), one end of the chain (5) is fixed to the bull gear (13) by means of rivets, and the main shaft of the bull gear (13) is a chain winding shaft (2). The hand brake further comprises a limiting device disposed on the chain winding shaft (2) between the bull gear (13) and the base (22); the limiting device comprises a first bearing (10), a torsion spring (11), a guide plate (9), and a guide plate holder (23). Installing the hand brake not only prevents the problem of the chain interfering with the movable pulley when the hand brake is deployed and thus affecting the performance of the hand brake, but also provides for a better appearance.
