[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The folding function of the propeller is realized by means of the connecting piece, the sleeve rod, the telescopic rod, the first storage groove, the first spring, the clamping block and the two clamping holes. The clamping block can be fixed by simply inserting the clamping block into the first clamping hole and rotating the sleeve rod so that the clamping block is inserted into the clamping ring, thereby making the propeller more convenient to carry.

[0016] 2. The functions of the UAV are improved by the landing gear, fixing block, mounting groove, airbag, mounting plate, gas cylinder and inflation tube. The UAV can land not only on the ground but also on the water. When landing on the water, the liquid level meter can detect that liquid has entered the inside of the mounting groove. At this time, the solenoid valve will be activated through the control center, and the compressed gas in the gas cylinder will quickly enter the inside of the airbag, popping the airbag out of the inside of the mounting groove, so that the UAV can float on the water.

[0017] 3. The material delivery function is realized through the horizontal plate, slide, vertical plate, bidirectional threaded rod, motor, lifting ring and fixed block. The materials are hung on the inner side of the lifting ring, and the motor is started to drive the bidirectional threaded rod to rotate, thereby driving the vertical plate to slide inside the slide, and then driving the two lifting rings to approach each other. The fixing can be completed until the fixed block is inserted into the slot. BRIEF DESCRIPTION OF THE DRAWINGS
