The invention discloses a socket adapter. The socket adapter comprises a socket body and a positioning disc; a positioning frame protruding downwards is arranged at the bottom of the positioning disc, two conductive rods are rotatably arranged on the positioning disc at the position of the positioning frame, the upper ends of the two conductive rods penetrate through first penetrating holes in the bottom of the socket body and are suitable for being electrically connected with a zero line terminal and a live line terminal respectively, and conductive inserting pieces extending transversely are arranged at the lower ends of the conductive rods; and the socket body is in linkage connection with each conductive rod through a linkage component, and when the socket body and the positioning disc rotate relatively, the conductive rods are driven to rotate through the linkage component, so that the conductive inserts are switched between a storage state in which the conductive inserts are stored in the positioning frame and a working state in which the conductive inserts extend out of the positioning frame. The socket adapter is reasonable in structure, when the socket adapter is installed, the positioning frame is inserted into the track groove of the track, then the socket body is rotated, when the socket adapter is disassembled, the socket body is rotated reversely, operation is convenient, and good practicability is achieved.
