step 1: firstly, a first support (1) and a second support (2) are fixed below an unmanned aerial vehicle through a third cushion (37) at the upper end, and a first spring (13) is abutted against the lower part of the unmanned aerial vehicle, when the unmanned aerial vehicle lands, a first supporting rod (4) and a second supporting rod (5) are buffered downwards and slide in a first sliding chute (14), and play a role of buffering through a second spring (16) below, and meanwhile, the first spring (13) enables a third movable plate (12) to transversely incline under the action of elastic force when the unmanned aerial vehicle subsides downwards, so that the damping effect is improved while a space is provided for the first spring (13);
step 2: meanwhile, when the first cushion (6) and the second cushion (7) below contact the ground, the third cushion can slide upwards under the action of the third spring (20) under the second sliding groove (18), the third spring (20) arranged at the upper end of the second sliding block (19) can play a role in shock absorption, and the third cushion can play a good role in shock absorption when being matched with a shock absorption structure of the upper part;
and step 3: when the third support bar (8) is lifted upwards, the second slider (19) above can contact the first movable block (21) and the second movable block (22), as shown in fig. 5, the inclination of the two sides of the second slider (19) is a mirror image of the first movable block (21) and the second movable block (22), therefore, when the second slider (19) is lifted upwards, the first movable block (21) and the second movable block (22) can respectively lift the fixture block (28) in the first movable plate (9) and the second movable plate (10) back to the sixth chute (27), so that the first movable plate (9) and the second movable plate (10) are ejected outwards under the action of the fifth spring (35), and because the fifth spring (35) is fixedly connected with the seventh chute (34), the elastic force of the spring rolling can be used for controlling the elastic force of the first movable plate (9) and the second movable plate (10) to eject outwards, the first movable plate (9) and the second movable plate (10) can be opened outwards to form a triangle on two sides of the first support (1) and the second support (2) to serve as a support when the unmanned aerial vehicle descends, and the landing stability of the unmanned aerial vehicle is guaranteed while the damping is achieved.
