An extension cord winding device includes: a frame body integrally formed with an upper frame and a lower frame; an extension cord having a plug at one end and a terminal socket at the other end uniformly wound around the upper frame; and a relay socket electrically connected at a middle place of the extension cord. The upper frame includes: a relay-socket supporting seat fixed on a top surface; a plurality of corrugated positioning grooves, together with a plurality of cord grips, which are located at each side of the upper frame; and a terminal-socket receiving chamber located at an end portion. The lower frame includes a plurality of cord holding members provided on each side, a plurality of supporting struts integrally formed at four corners, and a plurality of stabilizing angle plates movably connected to the supporting struts. The extension cords can thereby be used for making either a longer or a shorter electrical connection without becoming loosened or tangled, and the frame body can be conveniently hooked on an object or placed on a ground surface.
