ABSTRACT:
A magnetic altitude adjusting mechanism is described. The magnetic altitude adjusting mechanism includes a slide, a track, and a magnetic repulsive device. The slide including a magnetic piece is bar-shaped. The magnetic piece is configured in the slide. A longitudinal direction of the magnetic piece and a longitudinal direction of the slide are the same. The slide is coupled to the track so as to move along the track and be prevented from rotation thereon. The magnetic repulsive device is disposed on one end of the track to generate a magnetic repulsive force for fixing the slide on the track. The slide stops on a predetermined position with the magnetic repulsive force while an external force is released after the slide is adjusted to the predetermined position by the external force.
