Abstract
An electronic device is provided, including a first module, a second module, a control module, and a torsion hinge. The second module is rotatably disposed on the first module between a first position and a second position. The control module is slidably disposed on the first module between a third position and a fourth position. When the control module is in the third position, the second module is restricted to rotate with respect to the first module. When the control module is in the fourth position, the second module is released by the control module and rotatable with respect to the first module.
