ABSTRACT:
A retractable plug of power supply is comprised of a slide seat and a plug body. The slide seat is snap-fastened in a housing and metal pieces are arranged on sides of the plug body. An elastic lamella is disposed above the plug body, and a wedge block is located on the elastic lamella. The housing has a slot and a positioning hook part is provided on an inner wall face of the housing. A pushbutton is combined to the elastic lamella through the slot. The plug body is slidable in the slide seat by pushing the pushbutton in order to stretch metal pieces out of the housing. The metal pieces are prevented from being withdrawn into the housing by way of mutual retaining of the wedge and the positioning hook part, and such retaining could be released by pressing down the pushbutton to allow the withdrawal of the metal pieces into the housing.
