[0016] 1. In this solution, the positioning plate is installed at the bottom of the drone, and the drone is supported by the mounting plate and the support feet, which facilitates the take-off and landing of the drone.

[0029] In the embodiment, the positioning plate 1 is installed at the bottom of the drone, and the drone is supported by the mounting plate 2 and the supporting legs 3 to facilitate the take-off and landing of the drone. When the drone is landing, under the action of gravity, the mounting plate 2 and the supporting legs 3 on the outer wall will be pushed to deviate to both sides, thereby driving the T-bar 403 to deviate. Damping is set inside the buffer cavity on the mounting seat 401, and the buffer cavity and the buffer plate 402 cooperate with each other to facilitate buffering of the moving T-bar 403, and then buffering the mounting plate 2 and the supporting legs 3, thereby improving the landing stability of the positioning plate 1 and the drone.

[0030] Please combine the specific Figure 2 As shown, an abutment spring 404 is connected between the outer wall of each buffer plate 402 and the inner wall of the corresponding buffer cavity.

[0031] In this embodiment, the abutment spring 404 facilitates the resetting of the T-shaped rod 403 , and cooperates with the buffer cavity and the buffer plate 402 to further improve the use effect of the buffer mechanism 4 .
