Abstract

A mute hand winch includes a supporting system, a drive system and a braking system. The drive system includes a drive shaft, a capstan assembly and a first gear. Both the drive shaft and the capstan assembly are disposed at the base, the first gear is in threaded connection with the drive shaft, and the first gear is engaged with the capstan assembly. The braking system includes a second gear and a third gear. The second gear is sleeved on the drive shaft and is located at one side of the first gear. There is a gap between the first gear and the second gear. The first gear and the second gear are selectively attached and locked tightly to prevent the first gear and the capstan assembly from rotating. The third gear is fixed at the base, and the third gear has an unilateral bearing.
