摘要： A hinge capable of widely expanding includes an arc-shaped guide member, two movable members and two torsion generating members, wherein first guide rails are formed on two sides of the arc-shaped guide member, and a circular displacement track is defined by an arc center of the arc-shaped guide member. Each of the two movable members, respectively positioned on two sides of the arc-shaped guide member, is provided with a working surface contacting one of the first guide rails and an arc-shaped through hole penetrating therethrough. The arc center of the arc-shaped through hole is the same as the arc-shaped guide members'. Each of the two torsion generating members is assembled to the arc-shaped guide member through the arc-shaped through hole to which one of the two movable members belongs. The two movable members are guided by the arc-shaped guide member to move on the circular displacement track.
