The traditional plug design usually contains fixed zero line and live line plug, and in the case of need, it also includes the ground line plug to improve the electrical safety. For some heavy electric appliances, when only the zero line and the live line are inserted into the socket, the center of gravity may be unstable and fall off or loosen from the socket, which not only affects the convenience of use, but also may cause heating and even fire hazard due to poor contact. In addition, in the case of only two-hole socket available, the ground line plug in the traditional three-pin plug will become a redundant part, hindering the plug-in, and the applicability is limited. Some foldable plug designs have appeared in the market, but these designs are often complex in structure, inconvenient to operate, or have problems in stability, which cannot fully meet the market demand.
