Power plug with a freely rotatable delivery point

A power plug with a freely rotatable delivery point, comprising:

• a plug seat, an end surface of which is provided with an indented circular space, with a bottom of the space being provided with a center axis and the end surface being an open end;
• an armature which displaces forward and backward along an axial direction and a working plane of which is distributed with plural concentric conducting slip rings of unequal radii, with the armature being coaxial with the center axis, being installed in the indented space of the seat and being positioned radially by the seat;
• a turntable which is loosely connected at the open end of the seat along the same axis as the armature, the turntable being engaged with a tail end of the center axis;
• a set of insertion terminals, with an insertion end being vertically distributed on an outward radial surface of the turntable and a root part being extended with a plate-shaped elastic conducting probe which is extended respectively into and is in contact with the conducting slip ring of the armature;
• an electricity conducting element, an end of which is linked with and conducts the armature through the seat, and the other end is a delivery point;
• and
• an elastic arch element which operates indirectly between an interior of the seat and a longitudinal distance of the armature.
