[0002] The unmanned aerial vehicle, abbreviated as "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device, or is completely or intermittently autonomously operated by an on - vehicle computer. According to the application field, UAVs can be divided into military and civilian types, and are currently widely used in civil fields such as aerial photography, agriculture, and plant protection.

[0003] In the prior art, the UAV body and the connecting arm are of an integral structure and are generally not foldable, which makes the UAV occupy a relatively large storage space and is not convenient to carry. The traditional operation method for connecting the wing and the fuselage is to install each bolt and nut in cooperation. Due to problems such as the large number of bolts and nuts, the control of the assembly sequence and assembly tolerance, the technical preparation time of the UAV is greatly extended. When carried out, it is easy to squeeze the driver and cause damage and inability to fly. For this reason, we propose a detachable fixing mechanism for an unmanned aerial vehicle wing. Content of the Utility Model
