When the first magnetic module 130 rises, the distance between the first and second

magnetic modules

130 and 233 is decreased, so that the magnetic force between the first and second

magnetic modules

130 and 233 may be increased. In addition, when the first magnetic module 130 descends, the distance between the first and second

magnetic modules

130 and 233 increases, so that the magnetic force between the first and second magnetic modules 130 may be reduced.

According to an embodiment of the present invention, the user may rotate the rotating member 311 in the first direction (for example, counterclockwise direction) to elevate the first magnetic module 130. The spacing between the magnetic modules 130 may be reduced to increase the magnetic force.

On the contrary, the user can lower the first magnetic module 130 by rotating the rotating member 311 in a second direction (for example, in a clockwise direction), and accordingly, a gap between the first and second magnetic modules 130. This increase can reduce the magnetic force.
