By optimizing the machine arm folding mechanism, the weight can be significantly reduced, and the space occupation of the machine arm power assembly 2 in the non-running state can be reduced, and the overall performance of the structure can be improved.

[0025] The bottom of the foot support inclined strut 3 is provided with a support structure, which is used to enhance the stability and carrying capacity of the foot support. This design helps to improve the operation ability of the unmanned aerial vehicle on complex terrain and improves the start-stop stability of the unmanned aerial vehicle on complex terrain. Different load mechanisms can be directly installed on the foot support inclined strut 3 through the load fixing piece 5, and the modular design is adopted, which is convenient for quick assembly and disassembly, and improves the transfer efficiency of the unmanned aerial vehicle.

[0026] The load mechanism is used to carry pesticides, fertilizers or other agricultural materials, and the load fixing piece 5 is provided to ensure quick loading and unloading and operational convenience.

[0027] Specifically, as Figure 2As shown, the fastener is a foot screw 4, which is screwed through the main body 1 and connected with the foot brace 3. Through screw connection, the foot screw 4 can conveniently fix the foot brace 3 on the main body 1, and the threaded connection can bear a large load, which is suitable for components such as unmanned aerial vehicle footrests that need to bear a certain weight and impact force. The foot screw 4 can be equipped with anti-loosening measures such as spring washers or lock nuts to prevent the screw from loosening due to vibration during flight. When the foot brace 3 needs to be replaced or repaired, the screw-connected foot screw 4 is convenient for quick disassembly and reinstallation, with the characteristics of simple structure, convenient installation and high reliability. This connection method is suitable for the installation of the footrest of the plant protection unmanned aerial vehicle, which can meet the needs of quick assembly and disassembly, and is convenient for maintenance personnel to operate, achieving the purpose of improving the maintenance efficiency of the unmanned aerial vehicle.
