Claim:
A hinge assembly comprising: a first connecting member defining a first shaft hole; a second connecting member defining a second shaft hole; a first fixing member comprising a first fixing shaft and a first magnet attached to the first fixing shaft, the first fixing shaft extending through the first shaft hole and the first fixing magnet to be received in the second shaft hole; and a second fixing member comprising a second fixing shaft and a second magnet attached to the second fixing shaft, the second fixing shaft extending through the second shaft hole and the second magnet to be received in the first shaft hole, wherein the second fixing shaft defines a first through hole for receiving the first fixing member, and the second magnet defines a second through hole for the first fixing member extending through; wherein the south pole of the first magnet faces the south pole of the second magnet or the north pole of the first magnet faces the north pole of the second magnet, thereby providing a repelling force to prevent the first fixing member and the second fixing member from detaching from each other.
