The clutch operating end 611 corresponds to the position of the manual operating end 2 to realize that when the driving shaft 3 is operated by the manual operating end 2, the clutch is driven to cut off the power connection between the worm wheel 53 and the driving shaft 3. An electric operating device is added to realize automatic operation of the drive shaft, and the electric operating device is connected to the drive shaft through a clutch mechanism.
