[0032] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The adjusting assembly 7 includes grooves opened at the top of the landing plate 2 near both sides and an extension plate 71 located in the adjacent groove cavity. An opening is commonly opened near the rear side on the opposite side of the groove cavity, and a through-hole is opened on the rear side of the groove cavity on the other side. The through-hole inner cavity is movably penetrated by a connecting rod 76, and a push plate 75 is fixedly installed at the rear end of the connecting rod 76. A rack plate B73 is fixedly sleeved near the middle position of the outer periphery of the connecting rod 76. The bottom of the rack plate B73 is engaged with a rotating gear 74, and the bottom of the rotating gear 74 is engaged with a rack plate A72, and the front side of the rack plate A72 is fixedly connected to the adjacent extension plate 71.

[0033] Specifically, when a larger drone needs to be landed on the top of the landing plate 2, the two extension plates 71 can be moved to the opposite side under the limitation of the trapezoidal block 711 and the trapezoidal groove 712 with the cooperation of the adjustment component 7, thereby increasing the parking area on the top of the landing plate 2, which can be suitable for parking drones of different sizes and improve the scope of use of the device.

[0035] Specifically, by setting the trapezoidal block 711 to slide in the inner cavity of the trapezoidal groove 712, the extension plate 71 can slide stably in the inner cavity of the groove. By setting the buffer pad 713, the drone can be cushioned when it lands, and by setting the auxiliary light 714, the operator can park the drone on the extension plate 71 conveniently.

[0036] A support rod 741 is fixedly mounted on the rear side of the rotating gear 74 , and a rear end of the support rod 741 is rotatably connected to the rear side of the inner cavity of the groove.

[0039] Specifically, when the push plate 75 is moved, the bolt 753 can be taken out from the inner cavity of the threaded hole 754. When the push plate 75 is moved to the desired position, the end of the bolt 753 is threadedly connected to the inner cavity of the threaded hole 754 to facilitate limiting the position after movement.

[0040] Working principle: When using the utility model, the base 1 is placed in the desired position, and the position of the extension plate 71 can be adjusted according to the size of the drone. When adjusting the position of the extension plate 71, the bolt 753 is first removed from the inner cavity of the threaded hole 754, and then the plate 75 is pushed to the other side, thereby enabling the rack plate B73 fixed on the connecting rod 76 to move to the other side. Under the transmission of the rotating gear 74, the rack plate A72 can be moved to the side away from each other, thereby enabling the two extension plates 71 to move to the side away from each other, thereby increasing the parking area on the top of the landing plate 2 and being suitable for drones of different sizes. When the landing board 2 tilts to one side, the driving button 68 can be rotated at this time, and the worm 62 fixed on the driving button 68 can rotate the worm gear 63 engaged therewith, thereby rotating the threaded tube 64, so that the threaded rod 65 threadedly connected to the inner cavity of the threaded tube 64 can push the leveling block 66 to move upward under the limit of the connecting block 661 and the limiting telescopic rod 662, thereby adjusting the level of the landing board 2, and checking the adjustment effect through the spirit level 22. When the base 1 is used at night, the rear reflective strip 21 and the auxiliary light 714 can facilitate the operator to stably stop on the top of the landing board 2 through the camera.
