The first magnet 310 is configured to be a flat plate structure, the second magnet 410 is configured to be a circular truncated cone structure, and the first magnet 310 and the second magnet 410 are simple in structure and can reduce the manufacturing cost. A gap is formed between the first and second magnets 310 and 410 to prevent a repulsive force between the first and second magnets 310 and 410 from being increased, and to prevent an overall height of the first and second magnets 310 and 410 and the spacer columns 500 from being excessively increased.
