[0025] Specifically, the limiting members 1 are installed on the landing gear 3 of the unmanned aerial vehicle at intervals to define a limiting space in which the movement of the lifebuoy 2 in the horizontal direction and the vertical upward direction is limited, and the binding rope area 21 of the lifebuoy 2 is exposed at the interval between adjacent limiting members 1, so that the binding rope area 21 of the lifebuoy 2 is connected with the rudder mechanism of the unmanned aerial vehicle through the binding rope, and when the rudder mechanism of the unmanned aerial vehicle releases the binding rope, the lifebuoy 2 can be separated from the limiting space and dropped.

[0026] That is, the limiting members 1 are installed on the landing gear 3 of the unmanned aerial vehicle at intervals, which on the one hand can expose part of the lifebuoy 2, facilitating the connection of the lifebuoy 2 with the rudder mechanism of the unmanned aerial vehicle through the binding rope, and on the other hand can make the lifebuoy 2 contact with the limiting members 1 at least at two positions, so that the horizontal direction and the vertical upward direction of the lifebuoy 2 are limited to move, thereby ensuring that the lifebuoy 2 and the unmanned aerial vehicle can be relatively fixed during the flight of the lifebuoy 2 following the unmanned aerial vehicle, thereby avoiding safety accidents such as collision between the lifebuoy 2 and the propeller of the unmanned aerial vehicle, improving the dropping accuracy of the lifebuoy 2, and ensuring the timeliness and reliability of the rescue.
