ABSTRACT:
A string fastening device includes a reel on which a string is reeled thereon and a toothed ring is connected to the reel. A knob has a shaft inserted into a tube extending from the base of the device and the reel is rotatably mounted on the tube. The knob has first teeth in an underside thereof and the first teeth are engaged with the toothed ring so that the reel is driven by rotation of the knob to tighten the ring. The knob can be pulled away from the reel to disengage the first teeth from the toothed ring so that the string can be loosened. The knob includes second teeth and the base has two pawls which limit the knob to rotate in one direction to drive the reel.
