The disclosure discloses a novel power cord detachable structure for portable hair curler, including a power cord, an encapsulation is fixed to one end of the power cord, and an upper handle is fixed to the top of the encapsulation. By providing a fixing slot on the fixing sleeve and inserting the fixing sleeve into the appliance, the fixing sleeve is rotated to loose and fasten the fastener, thereby achieving the detaching effect. By providing and pushing the tail sleeve, the internal rotary lock is opened, the power cord is inserted into the product, the tail sleeve is loosened, and the fixing point inside the tail sleeve returns to the position where the lock is pushed, so that the power cord will not be detached. The tail sleeve is pushed so that the internal rotary lock is opened, and the power cord can be pulled out smoothly.
