The invention provides a two-phase and three-phase conversion multi-purpose plug. Conversion between a two-phase plug and a three-phase plug is realized. The plug is convenient for use and consists of a plug body, a ground wire pin, a ground wire pin seat, a pin roll, a pin roll seat, a zero wire pin, a fire wire pin, a zero wire pin seat, a fire wire pin seat, a front pressing plate and connection screws. The plug is characterized in that the ground wire pin, the ground wire pin seat and the pin roll are fixedly connected; the pin roll is arranged in a pin roll hole in the pin roll seat; the ground wire pin can rotate 90 degrees through the pin roll to fold and unfold; the zero wire pin and the fire wire pin are respectively fixedly connected with the zero wire pin seat and the fire wire pin seat; two annular segment protrusions are respectively arranged on the rearmost ends of the zero wire pin seat and the fire wire pin seat; two annular segment protrusions are respectively embedded into matched annular grooves of the plug body; and the annular grooves are incomplete grooves, which ensure that the zero wire pin and the fire wire pin rotate to a position at the angle of 60 degree of the three-phase plug from a parallel position of the two-phase plug.
Description
technical field [0001] The invention relates to the technical field of household appliance accessories, in particular to a multi-purpose plug capable of realizing mutual conversion between a two-phase plug and a three-phase plug. Background technique [0002] We use all kinds of electrical appliances at home or when we go out. The plugs of the electrical appliances are two-phase or three-phase. When using them, the following situations often occur. Sometimes there are only two-phase sockets, and the electrical appliances with three-phase plugs cannot be used. Sometimes there are only three-phase sockets. Electric appliances with two-phase plugs cannot be used, which brings inconvenience to life and work. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a multi-purpose plug with simple structure and convenient operation. It realizes mutual conversion between two-phase plugs and three-phase plugs, can ...
