<p>A hinge assembly includes a shaft, a follower and an elastic element. The shaft forms a projection. The follower defines a through hole and forming an inner peripheral wall surrounding the through hole. A threaded portion is formed on the inner peripheral wall, and the projection engages with the threaded portion of the follower. The elastic element provides an axial force to push the follower rotatable about and simultaneously longitudinally movable along the shaft.</p> |
