Movable hinge

A movable hinge to pivotally couple a base and a back panel of an electronic device, the back panel including a support portion and a housing compartment in the support portion, the movable hinge comprising:

• a first slide portion which is held in the housing compartment and includes a track portion and a first sloped surface connected to the track portion;
• and
• a second slide portion including a first pin with two ends respectively running through the track portion and fastening to the base, a butting portion coupled on the first pin and slidable thereon, and an elastic element coupled on the first pin and interposed between the butting portion and the base;
• the first pin being located at a bottom end of the track portion, the back panel being formed at a first position where the butting portion presses the elastic element to generate a return force thereof so that the butting portion is pushed by the return force of the elastic element to move along the first sloped surface to press the first slide portion to slide against the second slide portion and also drive the back panel to move against the base.
