Abstract

A hinge mechanism () includes a mounting member (), at least one retractable elastic shaft () and a rotating member (). The retractable elastic shaft has two opposite ends. The mounting member is located at one end of the retractable elastic shaft and defines at least one first hollow (). The rotating member is located at the other end of the retractable elastic shaft and defines at least one second hollow (). The first and second hollows respectively receive two ends of the retractable elastic shaft. The mounting member is rotatable relative to the rotating member to drive the retractable elastic shaft to move between a first position where the retractable elastic shaft is slantwise to an axis of the rotating member and a second position where the retractable elastic shaft is parallel to the axis of the rotating member. The hinge mechanism is easy to be manufactured.
