A hinge structure including a first shaft, a second shaft and a moving component is provided. The first shaft and the second shaft respectively have a guiding portion and a first screw thread and a second screw thread located at the guiding portion. Each of the first screw threads is connected to the corresponding second screw thread. The moving component is respectively coupled to the two guiding portions. When the first shaft and the second shaft rotate with each other through the moving component to switch between a first state and a second state, the moving component is guided by the first screw threads and the second screw threads to move along a direction parallel to the first shaft back and forth.
