US Patent 9368900 Power socket structure for outdoor electric extension line

A power socket structure for outdoor electric extension line is disclosed, comprising one or more power sockets, a socket body including a first pivotal axis and a second pivotal axis, a fixation case and a cone, wherein the cone is fixedly combined with at least a sidewall of the fixation case, and the socket body is pivotally connected onto the fixation case such that the socket body can rotate within the fixation case. Upon inserting a power plug of an electric product into the power socket, the power plug can bring the socket body to rotate within the fixation case so that the power socket of the socket body always faces towards the electric product thereby preventing the product power line of the power plug from wrapping around the socket body which may otherwise cause troublesome power line entanglements.
