One end of the threaded insertion rod 4 is a smooth rod, and the other end of the threaded insertion rod 4 is provided with a thread. When mounting the spraying tank 2, the quick installation mechanism can quickly fix the drone body 1 and the spraying tank 2 together. Cooperating with the stabilizing mechanism, the spraying tank 2 can be quickly and stably mounted on the drone body 1. It has high efficiency and can make the connection of the spraying tank 2 more stable, and no accidental falling accidents will occur.

[0040] Among them, the quick installation mechanism includes mounting plates 6, mounting grooves 7, limiting caps 8, and fixing caps 9. There are two mounting plates 6, and the two mounting plates 6 are respectively installed on both sides of the drone body 1. There are holes on the side walls of the two mounting plates 6 that cooperate with the threaded insertion rods 4.
