It has also been widely used in the agricultural field. It plays an increasingly important role in modern agriculture. It is mainly used in pesticide spraying, fertilization, crop monitoring, land surveying, pest and disease detection and other fields. It has the characteristics of high efficiency, low cost and strong applicability. However, as disclosed in a Chinese patent, an agricultural UAV (publication number: CN216943523U) has a body, a plurality of first arms uniformly arranged on the outside of the body in the horizontal direction, and a plurality of first arms hinged to the first arms in the horizontal direction. The second arm at the end, one end of the second arm is rotatably provided with a wing, the second arm is provided with a first connecting piece for connecting the first arm, and the first arm is provided with a second connecting piece for fixing the second arm; the utility model realizes the detachable connection between the first arm and the second arm and the folding of the second arm, and then fixes the folded second arm through the second connecting piece, so that the drone is a regular polygon after being folded and fixed, thereby ensuring the stability of the folding structure during transportation, ensuring that the second arm will not shake during transportation, and at the same time, the folded second arm reduces the space occupied by the agricultural drone during transportation, and reduces the transportation cost of the agricultural drone. However, in actual application, the fixed connection of the first arm and the second arm will lead to an increase in maintenance costs, and the bending and deformation caused during transportation will not be repaired by the operator in the field, and must be returned to the workshop to set up a maintenance station for processing, which greatly reduces the work efficiency. At the same time, the patented technology uses the support foot to be fixedly installed under the body, which cannot be applied to the mounting work of operating devices of different shapes and volumes, and has a narrow scope of application.
