An installation pole(12) of a semicircular shape is vertically installed in the other side of the installation plate. A plurality of supporting poles(20) is coupled in the installation plate. Two fitting pieces are formed on one end of the supporting pole. A connection bar(22) and an insertion hole(24) are formed on the other end of the supporting pole. An insertion groove is formed in both sides of a cut part of the insertion hole. After a cable is inserted in the insertion hole, a fixing piece(27) is inserted in the insertion groove for fixing the cable. A plurality of interval control devices(30) controls an interval between the supporting poles. Each interval control device includes a base plate and a cover. After the base plate is inserted in a space part of inside the cover, the connection bar of the supporting pole is inserted in the space part.
