PURPOSE: A plug is provided to minimize the space between a wall surface and an object, thereby maximizing space utilization. CONSTITUTION: A connection terminal(101) and a ground terminal are combined with a cylindrical main body(102). A rotating unit(111) rotates at 360 degrees in the horizontal direction. A penetration hole is formed in the center of the rotating unit. A cylindrical rotating unit(121) rotates within 180 degrees in the vertical direction. The rotating unit is inserted into the external diameter of an end of a wire(105).
