摘要:
A hand-propelled, self-driving, traveling machine that includes a clutch which enables transmission between a wheel and a transmission shaft. The clutch provides a drive state in which the transmission shaft drives the wheel to rotate and an unlocked state in which the wheel is rotatable relative to the transmission shaft. The clutch includes a driving member, combined with the transmission shaft, a movable pin, movable between a locked position in which the clutch is in the drive state and an unlocked position in which the clutch is in the unlocked state, a transmission member connected to the wheel, a movable friction member provided with a limiting slot, where the movable pin is partially disposed in the limiting slot, and a fixed friction member that is fixed to the chassis and that is in a frictional contact with the movable friction member.
