Abstract:
1. A transmission mechanism with the function of the shock absorption, comprising: a) a transmission unit adapted to receive a drive gear set within a housing; b) a motor coupled to the gear set and being mounted adjacent to and external the housing for providing the drive gear set with necessary driving power; c) a transmission rod disposed within the drive gear set to allow for a power transmission; d) a shock-absorbing unit including a fixing sleeve being disposed at the external side of the housing with respect to the internal end of the transmission rod, a shock-absorbing spring being installed within the fixing sleeve, and a telescopic lever being adapted to actuate the shock-absorbing spring; wherein said shock-absorbing spring is linearly displaceable and provides resistance to a linear displacement of said telescopic lever; and e) an adjusting unit interposed between the transmission rod and the shock-absorbing unit, the adjusting unit including: a rotating member having an internal rim with ring-shaped teeth corresponding to the ring-shaped sharp teeth of the push member as well as axial ribs corresponding to the guide grooves of the socket, the axial ribs further having an external rim abutting against a pad ring of the shock-absorbing unit.
