Abstract: A slide hinge is connected a cover to a base of a portable electronic device and has a stationary bracket, two pivot members, a sliding bracket and two torsion springs. The pivot members are mounted rotatably on the sliding bracket and are mounted to the base. The sliding bracket is mounted slidably on the stationary bracket and is mounted to the cover. The torsion springs are connected between the stationary bracket and the sliding bracket and each torsion spring multiple looped segments. The torsion springs with the looped segments provide an excellent resilient force to position the stationary bracket in one edge of the sliding bracket and therefore stably hold the cover in opened or closed positions without inadvertently sliding relative to the base.
