A moving mechanism is provided, including a torsion hinge, a slider, a lock member, and an elastic member disposed on the slider. The torsion hinge has a first plate and a second plate rotatable relative to each other. The lock member is rotatable relative to the first plate, and the slider is movably disposed on the second plate. When the moving mechanism is in a closed state, the lock member is engaged with a slot portion of the second plate, so as to restrict the second plate in a predetermined angle. When the slider slides relative to the second plate to a critical position, the elastic member pushes the lock member to release from the slot portion, such that the second plate is rotatable to an open position.
