Abstract
A hinge has a first bracket, a pivot pin, a second bracket and two torsion spring assemblies. The first bracket has a support and two holders. The pivot pin is mounted rotatably through the support and the holders on the base of the first bracket. The second bracket is mounted to the pivot pin. The torsion spring assemblies are mounted on the pivot pin and correspond respectively to the holders on the first bracket. Each torsion spring assembly has a disk and a torsion spring. The disk is mounted securely to the pivot pin and has a spring hook. The torsion spring is mounted around the pivot pin and has two ends. One end is mounted securely on the corresponding holder, and the other end is engaged detachably with the spring hook on the disk. The torsion springs provide a recovering force to keep the pivot pin from pivoting inadvertently.
