    Abstract: An electric stretching/collecting device for a parasol including a touch switch, a remote control circuit, a motor driving mechanism, a manually operated clutch mechanism and a ratchet damper mechanism. A motor serves to drive the motor driving mechanism to wind or unwind a cord for stretching/collecting the parasol. When the crank is switched, a clutching effect is provided to change the electrically driving operation into a manually driving operation. Therefore, the stretching/collecting device of the parasol is able to achieve double uses of manual and electric operation for conveniently stretching or collecting the parasol face.
