Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-6 The utility model provides a technical scheme:

[0024] As shown in Figure 1 , 2 , a take-off and landing foot support suitable for unmanned aerial vehicle surveying and mapping in rugged road sections, comprising unmanned aerial vehicle body 1, characterized in that the bottom of unmanned aerial vehicle body 1 is fixedly installed with two unmanned aerial vehicle body foot supports 2, the bottom of each of the two unmanned aerial vehicle body foot supports 2 is fixedly installed with a limiting mechanism 3, the top of each of the two limiting mechanisms 3 is provided with a compression mechanism 4, the side of each of the two limiting mechanisms 3 is fixedly connected with a telescopic mechanism 6, and the bottom of each of the two limiting mechanisms 3 is fixedly connected with two arc-shaped foot supports 5.

[0025] Specifically, as shown in Figure 3 , the limiting mechanism 3 comprises a limiting block 301, when the unmanned aerial vehicle body foot support 2 is placed into the limiting mechanism 3 and fixed, the limiting block 301 can effectively prevent the unmanned aerial vehicle body foot support 2 from being fixed unstably on the side and causing problems such as falling off, the limiting block 301 is additionally provided with a rubber sheet 305, the rubber sheet 305 is arranged in a wave-shaped arc, thereby increasing the friction between the unmanned aerial vehicle body foot support 2 and the limiting block 301 and reducing the damage caused by the unmanned aerial vehicle body foot support 2 to the inner wall, the limiting mechanism 3 is additionally provided with a side hole 302 on the side, thereby facilitating the installation and adjustment of the entire limiting mechanism, and the bottom end of the limiting mechanism 3 is fixedly connected with two support legs 304.

[0026] Specifically, as shown in Figure 1 , 3As shown, the bottom of each support leg 304 is fixedly connected with an arc-shaped foot 5, and the connecting point of the support leg 304 and the arc-shaped foot 5 is located at the middle of the length direction of the arc-shaped foot 5. This design can ensure uniform weight distribution and enhance the stability of the support on rugged ground. The opening angle between each pair of arc-shaped feet 5 is 40°, which effectively reduces the shaking of the UAV body during take-off and landing. The bottom of the arc-shaped foot 5 is attached with a rubber pad 501, which increases the contact area during take-off and landing, changes the linear contact to surface contact, and has a damping effect.

[0027] As shown in Figure 4 , the pressing mechanism 4 includes a pressing bolt 401, the bottom of which is fixedly installed with a pressing plate 404. The surface of the pressing plate 404 can be bonded with a layer of foam adhesive and has a hemispherical structure, which helps to increase the contact area with the UAV body foot 2 and is beneficial for fixation.
