Abstract
A hinge provides swiveling of a display relative to one side of a host body including a first fastening seat, a pintle, a second fastening seat, a main torsion anchor member, a torsion rotary member, an ancillary torsion anchor member, a compressed elastic reed assembly and a nut. The main torsion anchor member and the torsion rotary member are compressed by a returning force of the compressed elastic reed assembly. When the pintle pivots to a selected angle, the protrusion rapidly slides in a retaining latch trough of the main torsion anchor member through a steep sloped surface so that the display automatically and fully folds over the host body. The torsion rotary member pivots concurrently so that the bulged edge slides on a gradual sloped surface of different gradients so that adequate friction resistance is generated due to compression of the returning force of the compressed elastic reed assembly.
