[0041] Embodiment three:

[0042] On the basis of the first embodiment, a mobile control mechanism is disclosed, which includes a first magnetic block 11, a second magnetic block 13 and a trigger mechanism. The first magnetic block 11 is fixed above the protective block 7, the second magnetic block 13 is arranged above the mounting shell 8, and the second magnetic block 13 and the first magnetic block 11 are arranged with opposite magnetic poles.
