Specifically, the triggering mechanism comprises a pressed moving part, the pressed moving part is positioned right below the flood gate, and the falling force of the pressed moving part drives the pressed moving part to move downwards when the flood gate is closed. The connecting mechanism moving driving part comprises a pushing part 43 (in the form of a pushing rod in the embodiment) and a connecting part, one end of the pushing part 43 is connected with the lower end of the pressed moving part, and the other end is connected with one end of the connecting part; one end of the connection mechanism 42 detachably penetrates the lower end of the fixing portion and the upper end of the detachable sandwiching portion along the direction in which the pushing portion 43 pushes the connection portion to move, and the other end of the connection portion is connected to the one end of the connection mechanism 42.

In this embodiment, the guide bars of both guide slip mechanisms are located directly below the flood gate. When the guide rod receives downward pressure from the flood gate, the connecting block is driven to move downwards, so that one end of the pushing part also moves downwards, the other end of the pushing part moves outwards, and the connecting rod is pushed to move outwards. The connecting rod drives the connecting frame to move outwards, finally drives the connecting mechanism connected with the connecting frame to move outwards and separate from the lower end of the fixing part 413 and the upper end of the connecting base 412, at this time, the lower end of the fixing part 413 and the upper end of the connecting base 412 are automatically separated, and then the middle busbar and the detachable clamping part are detached together.
Further, the triggering mechanism further includes an elastic member 48, where the elastic member 48 is located below the pressed moving portion (in this embodiment, the connection block 45), and the connection block 45 generates a downward force on the elastic member 48 when the pressed moving portion moves downward.

And by setting the elastic coefficient of the elastic piece, misoperation of a system or artificial can be effectively avoided. If the connecting mechanism is pressed on the top end of the guide rod by people carelessly, the downward pressure given by a human body can only promote the elastic piece to compress for a small stroke due to the existence of the elastic piece, and the distance of the movement of the connecting mechanism is insufficient to achieve the purpose of separating the lower end of the fixing part from the upper end of the detachable clamping part.
