Patent attributes
A rotating shaft structure includes a damping component, a first shaft body and a second shaft body. A first limiting slot is disposed on a circumferential surface of the first shaft body. The damping component is located between the first shaft body and the second shaft body. The damping component includes one or more damping groups. Each damping group includes an elastic part and a first ball. The first ball abuts against the circumferential surface of the first shaft body by using elastic force of the elastic part. A second end of the elastic part is elastically connected to the circumferential surface of the second shaft body. In a rotation process of the first shaft body, the first ball rolls relative to the circumferential surface of the first shaft body and can be positioned in the first limiting slot.
