PURPOSE: A device for tightening a wire is provided to conveniently manipulate a device, thereby improving convenience for use and removing discomfort due to malfunction. CONSTITUTION: A device for tightening a wire includes a housing part(60), a reel part(40), a lifting cam part(30), a cam actuating part(20), a cam base part(50), and a rotary cover(10). The inner side of the housing part is cylindrical. A ratchet-type protrusion is formed on the upper side of the reel part. A slide protrusion is formed on the lower side of the lifting cam part, an outer peripheral cam groove part is formed on the outer periphery of the lifting cam part, and an inner peripheral cam groove part is formed on the inner periphery of the lifting cam part. The cam actuating part has a cam protrusive part rotating in one direction in order to lift the lifting cam part. The cam base part includes a guide cam part and a ratchet-type coupling part. The guide cam part guides the lifting of the lifting cam part. The ratchet-type coupling part is formed at the outer periphery of the cam base part, and restrains the one directional rotation of a ratchet-type gear. The rotary cover is coupled to the upper side of the cam actuating part, and integrally rotates with the cam actuating part. |
