<p>The present invention relates to a traction string. The traction string comprises: a head unit; a first connection unit extended from the head unit; a body unit extended from the first connection unit and having one side surface from which a plurality of friction increasing protrusion protrudes; a second connection unit extended from the body unit; and a fastening unit connected with the second connection unit and inserted into the head unit to be caught and fixed. The first and second connection units are relatively narrower in width than the body unit and the head unit. The fastening unit is relatively thinner than the second connection unit. The head unit includes a through hole into which the fastening unit is inserted; a protrusion integrally protruding from one side of the through hole; and a pushing piece extended from one side surface of the protrusion. The fastening unit has a slope surface formed on one side thereof and has a protrusion having a vertical surface and formed on the other side thereof, is caught on the protrusion to be fixed, and is released by operation of pushing piece to be separated from the through hole. According to the present invention, the traction string can be quickly and easily installed and separated as necessary by being formed in a cable tie-shape, can remarkably reduce manufacturing costs relative to the conventional traction string through a simple structure, and can be easily and conveniently used by the old and the infirm and female drivers without an external help by being easily installed and separated without a separate tool.</p> |
