[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The protection structure is used to install the base on the rotor of the unmanned aerial vehicle through the mounting frame, so that the rotor is located between the multiple protection frames. When the unmanned aerial vehicle collides with the building, the protection frame located on the outer side of the unmanned aerial vehicle first contacts the building, so that the support rod located on the outer side of the unmanned aerial vehicle rotates along the hinge point with the base. The support rod controls the deformation of the torsional spring during rotation, so that the impact force generated during the collision can be preliminarily buffered by the torsional spring.

The movement of the protection frame is buffered by the buffer assembly during movement, so that the impact on the unmanned aerial vehicle is further buffered. The impact force is not directly transmitted to the unmanned aerial vehicle and the internal parts when the unmanned aerial vehicle collides with the building, so that the unmanned aerial vehicle and the rotor are effectively protected.
