Under normal circumstances, the surface of the buffer plate 28 is pressed against the surface of the positioning block 27 by the elasticity of the coil spring. By setting a slidable connecting rod 23 and an automatically opened buffer plate 28, when the UAV takes off and lands, the connecting rod 23 and the buffer plate 28 can have a certain buffer through the strong pressure inside the side bracket 2. When the aerial photography UAV body 1 accidentally collides with an obstacle during the take-off and landing process, the slidable and automatically opened structure will provide a certain degree of buffering effect, reduce the risk of damage caused by the collision, protect the aerial photography UAV body 1 from damage, and is beneficial to protecting the aerial photography UAV body 1 itself and the surrounding environment. If an accident occurs during take-off and landing, the buffering effect of the device can reduce the damage caused by the collision to the UAV and the surrounding environment;

[0026] The booster assembly 4 includes a fixed block 41 fixedly connected to the surface of the aerial photography drone body 1, a sliding groove 42 is provided inside the fixed block 41, an electric telescopic rod 43 is fixedly installed inside the fixed block 41, a sealing plate 44 is fixedly connected to the output end of the electric telescopic rod 43, a sealing ring is fixedly installed on the outer surface of the sealing plate 44, a connecting pipe 45 is fixedly connected to the surface of the fixed block 41, an air leakage hole 46 is provided on the surface of the fixed block 41, the inner top end of the sliding groove 42 is connected to the outside of the fixed block 41 through the air leakage hole 46, and the inside of the sliding groove 42 is connected to the inside of the lateral bracket 2 through the connecting pipe 45 and the air intake pipe 21.

[0027] The inside of the buffer plate 28 is equidistantly connected to the roller 281 for rotation, and the surface of the roller 281 close to the positioning block 27 extends to the outer surface of the buffer plate 28.

At this time, the sealing ring 22 drives the connecting rod 23 to slide, so that the connecting rod 23 extends from the inside of the lateral bracket 2. When the connecting rod 23 is extended, the interior of the connecting rod 23 is also in a strong pressure state, so that the sealing block 24 drives the connecting plate 25 to slide. When the end of the connecting plate 25 away from the sealing block 24 extends to the outside of the connecting rod 23, the elasticity of the coil spring on the rotating shaft 26 opens the buffer plate 28 and abuts against the surface of the positioning block 27. When the main body 1 of the aircraft accidentally collides with an obstacle during take-off and landing, the sliding and automatically opening structure will provide a certain degree of buffering effect, reduce the risk of damage caused by the collision, and protect the main body 1 of the aerial photography drone from damage, which is beneficial to protecting the main body 1 of the aerial photography drone itself and the surrounding environment. If an accident occurs during take-off and landing, the buffering effect of the device can reduce the damage caused by the collision to the drone and the surrounding environment. By arranging two openable buffer plates 28 on each side bracket 2, the buffer plate 28 under the side bracket 2 can also support the main body 1 of the aerial photography drone during take-off and landing, providing more support for the main body 1 of the aerial photography drone and increasing its stability.
