Abstract

An extension lamp socket is disclosed and the extension lamp socket can be screwed into the screw connecting part of the conventional lamp socket for combination. The screw connector of a light bulb can be screwed in from the bottom end of the shell wall of the extension lamp socket and be fixed with the internal threaded convex body. In this way, the power source of the conventional lamp socket can be connected with the light bulb via the extension lamp socket. When installing a light bulb that occupies a large space, the extension lamp socket can be used to lower the screw connecting position. When installing a light bulb in a narrow or special space, the extension lamp socket can be used to extend the screw connecting position outward to facilitate installation of the light bulb.
