Expansion socket

The present invention relates to an expansion socket, and more particularly to an expansion socket that connects each of the sub-seats in a sliding manner.

Currently used power extension cords include a body having a plurality of jacks for providing a plurality of electrical plugs for plugging in. However, the number of jacks on the conventional power extension cord does not necessarily meet the needs of each user, and it is not possible to flexibly expand or reduce the number of jacks as the user desires, and there is a need for improvement.

Taiwan's new patent No. M498978 "Building Block Socket Structure" discloses a power socket that can expand or reduce the number of power sockets according to the needs of users. The socket structure disclosed in the prior patent is on a body.
