Shell 8 is " L " shape, and is one-body molded.

With reference to Fig. 3 and Fig. 4, the concrete course of work can be divided into three phases:

Reset: the 3rd electric connection line 93 and the 4th electric connection line connect 94 and power connection, the second coil rack 41 energisings, produce electromagnetic force, attract the second slide bar 31, the motion of the second slide bar 31 drives 33 motions of coupled connector, connector 33 compression the second springs 32, and drive banking stop 34 and move inwards and be in vertical state, the first slide bar 12 no longer kept out.The first slide bar 12 moves downward under the elastic force effect of the first spring 11, until blocked by block 14.

Closed: the first electric connection line 91 connects positive source, and the second electric connection line 92 connects power cathode.This moment, 21 energisings of First Line ring framework, produced electromagnetic force, and consistent with the magnetic force direction of magnet 23.Under the acting in conjunction of magnet 23 and electromagnetic force, the first slide bar 12 moves upward rapidly, compression the first spring 11.After motion finished, the second spring 32 was upheld, and outwards moved at the effect lower limit bit slice 34 of the second spring 32, was in heeling condition.After outage, it is motionless that the first slide bar 12 keeps under the attraction force acts of magnet 23, and state at this moment is not very stable, if the first slide bar 12 has broken away from magnet 23, banking stop 34 can prop up the first slide bar 12.

Open: the 3rd electric connection line and the 4th electric connection line connect and power connection, and the first electric connection line 91 connects negative pole simultaneously, and the second electric connection line 92 connects positive pole.

The second coil rack 41 energisings produce electromagnetic force, attract the second slide bar 31, the motion of the second slide bar 31 drives 33 motions of coupled connector, connector 33 compression the second springs 32, and drive banking stop 34 and move inwards and be in vertical state, the first slide bar 12 no longer kept out.
