A hinge structure for an electronic device including a first part and a second part is provided. The hinge structure includes a first fixing base, a second fixing base, a rotating element, and a control element. The first fixing base connects to the first part. The second fixing base connects to the second part and includes a first locking structure. The rotating element includes a second locking structure. An end of the rotating element rotatably and movably connects to the first fixing base along an axial direction. The other end of the rotating element engages with the first locking structure through the second locking structure. The control element extends to the rotating element for driving the rotating element to move along the axial direction.
