The present invention relates to a folding plug which has two bottom slots at center of a base while the bottom slots are extended outward with two receiving slots disposed in parallel. Two shaft supports are interposed in parallel between the bottom slots, and the middle section of the shaft supports is fitted with a dished member. Besides, a locating recess is laterally interposed between the shaft supports. When a cover with a press bar is covered on the base, the dished member of the shaft supports is placed upon the shaft used to connect the prongs. The shaft is clamped between the shaft supports of the base and the press bar of the cover so that the prongs are swiveled between the bottom slots and the receiving slots at different angles. In addition, at least two locating flanges are mounted on the rim of said shaft, and the engagement state of the locating flanges of the shaft with the locating recess is changeable so that the prongs can be located at all prearranged angles for different applications.
