[0002] A drone, as the name suggests, is an unmanned aircraft. Since the birth of the airplane in the early 20th century, people at that time had proposed the idea of ​​unmanned aircraft due to considerations about the safety of flying aircraft. It was not until the 1930s that the British Ferrer Company converted a "Queen" twin-wing fixed-wing aircraft into an unmanned target aircraft, marking the beginning of the entry of drones into aviation history.

[0003] According to a Chinese patent with publication number "CN211893673U", a UAV flight anti-collision device is disclosed, including a UAV body, an anti-collision body is fixedly installed on the top of the UAV body, a first bolt is movably provided on the top of the anti-collision body, a connecting rod is movably provided on the bottom of the UAV body, a sliding ring is movably provided on the outer wall of the connecting rod, a first anti-collision rod is fixedly installed on the outside of the sliding ring, the first anti-collision rod is distributed in a "cross" shape on the outer wall of the sliding ring, a first anti-collision ring is fixedly installed on the outer wall of the first anti-collision rod, an electric telescopic device is fixedly installed on the bottom of the connecting rod, a second anti-collision ring is fixedly installed on the bottom of the electric telescopic device, a second anti-collision rod is fixedly installed on the inner wall of the second anti-collision ring, and the anti-collision bodies are symmetrically distributed on the top and bottom of the UAV body.

By setting up two anti-collision rings, the anti-collision effect of the drone body in the horizontal direction is achieved. By setting up the anti-collision body, the anti-collision effect of the drone body in the vertical direction is achieved, and the anti-collision effect is good. However, the above structure cannot achieve an effective protection effect, and cannot directly and effectively protect the rotor, which results in the above device having low protection performance and inconvenience in use, and increases the drone's own gravity too much, resulting in the drone being unable to be flexibly used.

[0014] Second, when in use, the upper end of the main body can be protected by the action of multiple guardrails, and the front and rear of the main body can be protected by the action of the buffer rod and the buffer plate. When the buffer plate is collided, the movable rod moves toward the inside of the buffer sleeve, so that the buffer plate can be buffered under the action of the buffer spring, thereby increasing the protection effect.
