<p>The present invention provides a dual-pawl type ratchet buckle, in which several pawls, each having a stop, contact sawteeth of a strap at different positions, so that the strap can move in minute units of distance rather than in units of one pitch. In the present invention, the strap is placed between opposite plates (110) provided on the base (100), and a lever (200) is coupled to the opposite plates. Furthermore, the dual-pawl type ratchet buckle includes a pawl unit (300). The pawl unit comprises an inner pawl (310) and an outer pawl (320), which are provided on the same shaft and rotatably coupled to the opposite plates, and each of which has a spring so as to be returned to an original position thereof. The stops (303) are provided on ends of the inner and outer pawls which face the lever. The ends of the inner and outer pawls on which the stops are provided are in contact with the sawteeth at different positions. Thus, the distance that the strap is moved can be minutely adjusted.</p> |
