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 bearing I (10), a torsion spring holder (12), a torsion spring (11), a guide plate (9), and a guide plate holder (23); the torsion spring (11) is sleeved on the outside of the bearing I (10). a stopper post III (7) is secured to the side of the torsion spring holder (12) facing the spring; a stopper post I (8) is secured to the side of the guide plate (9) facing the torsion spring (11); a stopper post II (26) is secured to the side of the base (22) facing the guide plate holder (23); the stopper post II (26) passes, by means of a hole, through the guide plate holder (23) and rotates in the arcuate groove of the guide plate (9). The center distance between the drive shaft (16) and chain (5) which is on end of the chain winding shaft (2) is increased by 47 mm; 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.
