Abstract
A hinge provides swiveling of a display relative to one side of a host body includes a first fastening seat, a pintle, a second fastening seat, a main twisting set, a positioning friction plate, an ancillary twisting set, a compressed elastic reed assembly and a nut. The main twisting set has a main rotary member compressed by a returning force of the compressed elastic reed assembly. When the pintle pivots to a selected angle, the protrusion of the main rotary member rapidly slides in a retaining latch trough through a steep sloped surface so that the display can automatically and fully fold over the host body. The main rotary member and the ancillary rotary member turn concurrently and respectively on the steep sloped surface and a gradual sloped surface so that adequate friction resistance is generated due to compression of the returning force of the compressed elastic reed assembly.
