Meanwhile, the limiting plate 46 rotates rapidly to drive the lifting plate 22 to move downwards rapidly, the permanent magnet 222 moves rapidly at the moment, the magnetic induction coil 23 generates current exceeding a threshold value, and the outage triggering mechanism 2 sends out an outage signal outwards. When the problem is solved, the breaking net plate 44 can be manually restored, and the breaking trigger mechanism 2 and the ejection mechanism 3 are driven to restore to the initial positions.
