Second buffer springs 415 are sleeved outside the two guide sliding rods 413.

[0025] As Figure 1 , Figure 2 , Figure 3 As shown, the bottoms of the two buffer air bags 407 are respectively fixedly connected to the bottom of the inner cavity of the two sleeves 406, and the tops of the two buffer air bags 407 are respectively fixedly connected to the bottom ends of the two sleeve rods 405.

[0026] As Figure 1As shown in the figure, the moving component 5 includes a double-headed motor 501 disposed inside the slot 3.

By using the two connecting shafts 504, the bottom plate 505 is pushed downward until the universal wheels 506 contact the ground, enabling the movement of the take-off and landing platform body 1. When the unmanned aerial vehicle lands on the top of the support plate 402, the support plate 402 moves downward under the impact force, squeezing the first buffer spring 408 and the elastic sheet 410. At the same time, the sleeve rod 405 moves into the inside of the sleeve 406 to squeeze the buffer airbag 407, which can buffer the impact force. Subsequently, the shock absorber seat 401 moves downward, and the two rotating shafts 411 rotate. At the same time, the two guiding sliders 414 are pushed to slide on the surface of the guiding slide rod 413 to squeeze the second buffer spring 415, which can buffer the impact force for the second time, avoiding damage to the parts inside the unmanned aerial vehicle caused by the vibration generated when the unmanned aerial vehicle falls.
