1. A rotating mechanism, comprising:
a rotating shaft;
a first mechanical part, wherein a first slide groove extends in the first mechanical part;
a second mechanical part, wherein a second slide groove extends in the second mechanical part;
a third mechanical part, wherein a first end of the third mechanical part is connected to the rotating shaft, and a second end of the third mechanical part is disposed in the first slide groove;
a fourth mechanical part, wherein a first end of the fourth mechanical part is connected to the rotating shaft, and a second end of the fourth mechanical part is disposed in the second slide groove; and
an elastic component, wherein the elastic component is sleeved on the rotating shaft, or is clasped on the rotating shaft, or is sleeved on the third mechanical part or the fourth mechanical part;
wherein the first mechanical part, the second mechanical part, the third mechanical part, and the fourth mechanical part are configured in a manner that, when the first mechanical part and the second mechanical part rotate around the rotating shaft, the second end of the third mechanical part slides with respect to the first slide groove, and the second end of the fourth mechanical part slides with respect to the second slide groove; and
wherein the elastic component is sleeved on the rotating shaft, or is clasped on the rotating shaft, and the elastic component is configured in a manner that:
when the first mechanical part and the second mechanical part are in a folded state or an unfolded state, deformation of the elastic component is a first deformation; or
when the first mechanical part and the second mechanical part are in a state between folded and unfolded states, deformation of the elastic component is a second deformation; or
wherein the elastic component is sleeved on the third mechanical part or the fourth mechanical part, and the elastic component is configured in a manner that:
when the third mechanical part has a first positional relationship with a cam, deformation of the elastic component is the first deformation; or
when the third mechanical part has a second positional relationship with a cam, deformation of the elastic component is the second deformation; and
wherein a deformation value of the second deformation is greater than a deformation value of the first deformation.
