Abstract:
The invention relates to communications technologies and discloses a rotation axis, a digital device and a Universal Serial Bus (USB) device. The rotation axis includes a sleeve, an elastic body, a concave washer, and a movable support. The sleeve includes a lip and a cylinder. The elastic body, the concave washer, and the movable support are disposed sequentially around the cylinder with the lip adjacent to the elastic body along the axial direction of the cylinder beginning with the lip. A number of concaves are disposed on one end-surface of the concave washer and distributed on a circle. The end-surface of the concave washer where the concaves are disposed contacts one end-surface of the movable support. A number of protrusions are disposed on the end-surface of the movable support to mate the concaves. In the invention, a rotation axis is constituted by a few parts including a sleeve, an elastic body, a concave washer, and a movable part. Therefore, the rotation axis is characterized by simple structure, small size, low cost, and good reliability.
