The specific principle of the invention is as follows:

(1) when the unmanned aerial vehicle lands, the buffer seat 504 in the first buffer assembly 5 is firstly contacted with the ground, the bottom of the buffer seat 504 is provided with a rubber buffer cushion which can firstly play a part of shock absorption function, after the buffer seat 504 is contacted with the ground, the ground provides an upward acting force for the buffer seat 504, the buffer seat 504 slides upwards relative to the first support column 502, the first buffer spring 506 is compressed to generate elastic deformation, so that the buffer function is played, and the spring force of the first buffer spring 506 ensures that the buffer seat 504 is not contacted with the bottom of the base 3;

(2) thereafter, the second damping assembly 7 is in contact with the ground, which contact of the second damping assembly 7 with the ground will result in three movements:

a. firstly, the rotating arm 704 is driven to rotate around the second arm body 714, and the bottom of the rotating arm 704 is spread outwards at the time, because the bottom of the rotating arm 704 is provided with a universal joint and a roller, the friction force with the ground is small at the time, and the rotating motion of the rotating arm 704 is buffered by the third buffer spring 710;

b. when the rotating arm 704 moves to the maximum limit, the force applied to the rotating arm 704 by the ground will be divided into a first component force directed vertically upwards and a second component force directed horizontally outwards, and the first component force will make the second arm 714 move upwards relative to a first arm 712, thereby compressing the second spring and playing a role of buffering;

c. the second component force drives the first arm 712 to slide in the second sliding groove and the first sliding block 904 to slide in the first sliding groove 902, so as to be expanded outwards;

the invention can play a role in buffering when the unmanned aerial vehicle lands, can also ensure the stability of the unmanned aerial vehicle when the unmanned aerial vehicle lands, and effectively solves the problems encountered in the prior art.
