PURPOSE: A concent unit for embedding a power cord is provided to lead out a cable from a unit body and electrically connect a plug to a multi-tap. CONSTITUTION: A unit body(110) is formed as an external box(112) and a cover(114) for forming an external shape with a uniform size. A heating plug(116) is composed at an external side of the cover(114) of the unit body(110), and is electrically combined with a power concent. A ratchet wheel(120) is rotatably installed in the external box(112). A plurality of uni-directional ratchets are formed in a radial manner in the ratchet wheel(120). A spiral spring box(130) is installed in an upper portion of the ratchet wheel(120). An external side end of a spiral spring(132) is connected to one side of an internal portion of the spiral spring box(130). A driving reel(140) is installed in an upper portion of the spiral spring(132), and a cable is wound on the driving reel(140). A multi-tap(150) is composed at an external end of the cable wound on the driving reel(140), and a plurality of power connection holes electrically connected with a plug of an electric instrument are formed in the multi-tap(150). A circular contact point copper plate(160) installed at an upper side of the driving reel(140) electrically connects the heating plug(116) to an internal end of the cable. A spiral spring fixing hole(112a), protruded and formed on an internal surface of the cover(114) of the unit body(110), fixes an internal side end of the spiral spring(132). A multi-tap bridging and maintaining device having a multi-tap safe reception portion(170), a snap bridging flap and a snap bridging groove maintains the multi-tap(150) at one side of the unit body(110). A ratchet wheel bridging and maintaining device having a ratchet bridging flap(180) and an elastic spring(182) bridges and maintains the ratchet wheel(120) so that the loosened state of the cable is maintained. A ratchet wheel release button(190) releases the ratchet wheel bridging and maintaining device so that the cable is wound on the driving reel(140) by a recovery force of the spiral spring(132).
