In order to improve the reliability of a product through stable operation when a user fastens a wire, the present invention provides a wire fastening apparatus comprising a housing, a winding member, a gear member, a spring part, and a knob part. The housing includes a support protruding in a radial direction above a coupling shaft, which protrudes upwardly from the center of the bottom surface. A latch type gear in one direction of the circumference is formed on the inner circumference of a lateral wall portion of the housing. The winding member is inserted into the housing to be able to rotate, wherein a wire is selectively wound on the winding member. The gear member includes a wing part formed at the edge of the gear member, and a molding restriction part, which is selectively molded to the latch type gear and thus the rotation thereof in one direction is restricted, is formed at the end portion of the wing part. A penetration hole is formed in the center of the gear member, and thus the gear member is selectively elevated, and detached from the winding member. The spring part is disposed above the gear member, and is in a close contact with the external circumference of the support by elastic restoring force so as to selectively keep the elevation state of the gear member. The knob part includes a press protrusion protruding downward, wherein the press protrusion presses the spring part toward the support at the time of rotation in the other direction. The knob part is coupled with the gear member to cover the top side of the gear member. |
