[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment or their own programmed control devices. UAVs can perform various missions without a pilot. They can fly autonomously according to pre-programmed flight plans or adjust their flight paths in real time under the control of a ground control station. The structure of heavy-load UAVs mainly consists of the fuselage, power plant, landing gear, and avionics control system. With the continuous increase in the weight of payloads, the requirements for UAVs' carrying capacity are becoming increasingly stringent. This necessitates larger fuselage structures, resulting in a larger overall space footprint and hindering space utilization.

[0003] Based on the above, the following problems were found: the current medium and large-sized drones are generally too large in size, making storage and transportation inconvenient, and the installation process is cumbersome and inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a quick-release structure device for the powered arm of a large UAV, in order to achieve a more practical purpose. Utility Model Content
