Abstract
The invention relates to a double spring winder for the power cord of a cleaner. The winder comprises two tub wheels and two disciform springs arranged at rotary tables outside the tub wheels; the power cord is wound around the tub wheels of the winder. A reversing gear is arranged between the two disciform springs so as to cause the screwing directions of the two springs to be opposite. The original position for the two springs renders an elasticity difference to cause the cord to return. When the power cord is pulled out from the tub wheels of the winder, the tub wheels rotate, one spring screws forward and the other spring screws backward; when the power cord is returned, the tub wheels rotate reversely, the spring screwing forward becomes slack and releases elasticity collected, the spring screwing backward screws forward and collects elasticity and the power cord is wound around the tub wheels of the winder. Therefore, under the function of the unchanged elasticity difference between the two springs, the power cord long pulled out can be returned safely at homogeneous velocity and the problem of damage caused by quick return of the power cord to users in the prior art can be solved.
