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.

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.
