[0029] The working principle of this device is as follows: first, connect the male connector 4 with the female connector 6. During the connection process, the guide groove 10 is combined with the guide block 7 to guide and limit the female connector 6 when the female connector 6 is inserted into the male connector 4. During the plugging process, the female connector 6 will apply external force to it through the inclined surface of the limit rod 11, thereby causing the linkage plate 16 to push the spring 15 and the telescopic column 14 to compress. When the limit rod 11 is in the position of the limit hole 8, the limit rod 11 can be automatically placed in the limit hole 8 by relying on the resilience of the telescopic column 14 and the spring 15, thereby realizing the connection and fixation of the two. The connection can be made in one step. After the connection is completed, the drone body 1 can lift the water hose 9, and the water in the water hose 9 can be sprayed out through the sprinkler pipe 3 to extinguish the fire.
