In addition, by rotating the extension rods 808, they can be rotated to relatively flat positions respectively, thereby ensuring the stability of the drone landing platform. In order to enable the drone to land on At the top of the horizontal support platform 1, the electronic level 2 is first turned on through the controller 3 to detect whether the support platform 1 is stable.

When the multiple slots 5 are rotated to the positions corresponding to the multiple positioning tubes 708, they can be moved to the inside of the corresponding slots 5 under the elastic action of the multiple springs 707, and then the three threaded rods 802 are respectively moved. The three threads are rotated into the corresponding threaded tube 801, thus realizing the connection between the take-off and landing platform and the supporting structure. Then, the three extension rods 808 are placed on the ground, and the UAV can be landed on the top of the supporting platform 1.
