[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-5 , a drone landing gear, the package is arranged at the bottom of the drone 1,

[0026] The landing gear 2 includes a support plate 3 connected to the drone 1 by bolts. Four annular grooves are formed on the surface of the support plate 3. The annular grooves serve as mounting grooves for the bolts. The bolts pass through the annular grooves and are connected to the screw holes on the shell of the drone 1. Four card slots 301 are formed at the bottom of the support plate 3. Four sets of limit members matching the card slots 301 are formed at the bottom of the support plate 3.

[0027] The limiting member includes two pairs of T-shaped slots 302 and two pairs of limiting slots 303 opened at the bottom of the support plate 3. The T-shaped slots 302 are connected to the limiting slots 303, and the limiting slots 303 are connected to the card slot 301. A sliding block 4 is slidably fitted in the T-shaped slots 302, and a limiting plate 5 is connected to two adjacent sliding blocks 4.

[0028] In order to make the sliding block 4 slide in the T-shaped sliding groove 302, as shown in FIG. Figure 4 and Figure 5 As shown, the sliding block 4 is in an inverted "T" shape.

[0029] In order to make the limiting plate 5 limit the top plate 601, as shown in FIG. Figure 4 and Figure 5 As shown, a mounting groove 401 is provided on the sliding block 4, a pair of springs 402 is provided in the mounting groove 401, the pair of springs 402 is fixedly connected to the limiting plate 5, and a handle is provided at the bottom of the limiting plate 5.

[0030] A top plate 601 is clamped in the slot 301, and a pair of grooves 6010 are provided on the top plate 601, and the grooves 6010 cooperate with the limiting plate 5. A support rod 6 is provided at the bottom of the top plate 601, and a special-shaped rod 602 is provided at the bottom of the support rod 6. The special-shaped rod 602 is provided with a pair of short rods 603 inclined downward.

[0031] When the support rod 6 is accidentally damaged, the user pulls the handle downwards, and the handle drives the limit plate 5 to stretch the spring 402, so that the limit plate 5 moves out of the groove 6010, releasing the limit on the top plate 601, and then slides the limit plate 5 to one side. After loosening the limit plate 5, the top plate 601 can be removed from the slot 301 for replacement, so that the user can quickly and conveniently disassemble and replace the support rod without using professional tools, which reduces the user's operating difficulty, saves maintenance time, and greatly improves the use efficiency and convenience of the drone 1.

[0032] Furthermore, if Figure 3 As shown, the special-shaped rod 602 includes a cross bar and arc-shaped rods arranged at both ends of the cross bar, a rubber sleeve is arranged on the surface of the cross bar, and a short rod 603 is arranged on the arc-shaped rod.

[0033] When the drone 1 tilts forward or backward due to uneven ground during landing, as the angle of the arc rod changes, the short rod 603 will contact the ground in advance, thereby supporting the entire device. Therefore, after the drone 1 lands, it can prevent the drone 1 from tipping over due to uneven ground or wind, ensuring the stability of the drone 1 landing, thereby protecting the drone 1 and its internal equipment, and ensuring the safety of the drone 1.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
