The cover 1 is rotatable relative to the body 2 to open and close the cover 1. In the process that the cover body 1 rotates relative to the main body 2, the second connecting assembly and the cover body 1 integrally rotate, and the second connecting assembly is connected with the first connecting assembly and rotates relatively.

Further, the surface of one of the first connecting component and the second connecting component is provided with a sliding groove, the other one is provided with a salient point 38, and the salient point 38 is matched with the sliding groove. Wherein, under the condition that the main body 2 and the cover body 1 relatively rotate, the salient points 38 move in the sliding grooves. Namely, the salient points 38 and the sliding grooves are correspondingly arranged on the two connected surfaces, the sliding grooves correspond to the positions of the salient points 38, and the salient points 38 can be inserted into the sliding grooves and move along the sliding grooves.

Further, the groove depth of the sliding groove changes from one end of the sliding groove to the other end of the sliding groove. In this embodiment, the groove depth of the sliding groove is changed, and different extrusion forces are generated on the protruding points 38 by the change of the groove depth of the sliding groove, so that different rotation friction forces are formed between the first connecting assembly and the second connecting assembly, and the force feeling when the cover body 1 is rotated, opened and closed relative to the main body 2 is influenced. Specifically, the larger the chute depth is, the smaller the extrusion force to the salient points 38 is; the smaller the groove depth, the greater the pressing force on the bump 38. Therefore, in the process that the cover body 1 rotates relative to the main body 2 to open and close, when the salient points 38 move to the positions with smaller groove depths of the sliding grooves, the extrusion force between the sliding grooves and the salient points 38 is larger, so that the rotation resistance of the cover body 1 is increased; when the salient points 38 move from the positions with smaller groove depth of the sliding grooves to the positions with larger groove depth of the sliding grooves, the extrusion force between the sliding grooves and the salient points 38 is reduced, so that the salient points 38 generate restoring force towards the sliding grooves, the salient points 38 can move continuously along the sliding grooves, and the self-force-generating experience is realized.
