The second casing may be a casing where a screen of the notebook computer is located.

The single-axis hinge is provided with a connecting arm 3, a first end of the connecting arm 3 is rotationally connected with the first connecting frame 1, a second end of the connecting arm 3 is rotationally connected with the second connecting frame 2, and a second shell connecting position 20 on the second connecting frame 2 is spaced from the axis of a rotating shaft 32 of the connecting arm 3 to the second connecting frame 2, so that the rotating angle range of the second shell connecting position 20 on the second connecting frame 2 relative to the first shell connecting position 10 on the first connecting frame 1 is larger than that of the connecting arm; taking the maximum opening angle of the mobile terminal as the flattening as an example, from folding to flattening, the rotation angle of the second housing connection part 20 relative to the first housing connection part 10 is 180 °, and the rotation angle of the connection arm is a certain angle smaller than 180 °, which can be specifically determined by the rotation limit. The rotational limit of the connecting arm 3 may be provided on the first connecting frame 1. And the rotation limit of the second connecting frame 2 can be arranged on the second connecting frame 2 to be matched and limited with the connecting arm 3.

The single-axis hinge is also provided with a torsion mechanism, and the torsion mechanism is arranged on the first connecting frame 1 and is connected with the second connecting frame 3 through a sliding connection structure of a pin and a chute.

The torsion mechanism comprises a swing arm 4, the swing arm 4 is rotationally connected with the first connecting frame 1, a shaft 40 which is rotationally connected with the connecting arm 3 is not on the same axis but is parallel to a shaft 32 which is rotationally connected with the first connecting frame 1, an elastic mechanism and a friction structure pressed by the elastic mechanism are arranged on the shaft 40 which is rotationally connected with the swing arm 4 and the first connecting frame 1, and the swing arm 4 is connected with the friction structure; the swing arm 4 is provided with the pin 41, and the second connecting frame 2 is provided with the chute 21. In the present embodiment, the friction structure includes a first cam 51 and a second cam 52, the first cam 51 and the swing arm 3 are connected, and the second cam 52 and the first cam 51 are pressed by a spring 53.
