  • Patent number: 8720012
    Abstract: A fastener for a document folder includes a base plate, a hook bracket and torsion springs. The front end of the base plate is extended upwards and curled to form a bending section. A slot is formed by the surrounding of the bending section. Rotating shafts on two sides of the front end of the hook bracket are respectively arranged at two ends of the inside of the slot. The torsion springs are respectively sleeved on the rotating shafts on two sides of the front end of the hook bracket. Some ends of the torsion springs are fixed on the rotating shafts and the other ends of the torsion springs are fixed on the base plate. End sections of the rotating shafts are bent upwards to form retaining sections. Clamp holes are engaged with the retaining sections and used for fastener opening formed on the front of the bending section.
