A rotational outlet-socket includes an outlet-socket group including at least two outlet-socket units connected in series, and each outlet-socket unit separately performing rotation in a plurality of angles, where an electric conduction member group is disposed in the outlet-socket unit and includes a first electric conduction rod including a first clamping portion, a second electric conduction rod including a second clamping portion, and a ground wire electric conduction rod including a ground wire clamping portion, and the ground wire clamping portion is pivotally connected to and pivots around the ground wire electric conduction rod through a pivotal connection portion by using a pivotal connection piece. The ground wire clamping portion pivots around a rotation axis between the first clamping portion and the second clamping portion when the outlet-socket unit rotates.
