[0003] In order to prevent the wings of a drone from colliding with foreign objects and causing the drone to crash, existing drones usually have protective railings installed on the outside of their wings. However, the protective railings usually have a simple structure and are not equipped with a buffer component. When encountering a large impact, the drone is easily damaged. In addition, the protective railings are usually installed on the drone through structures such as screws, which are not convenient to disassemble. Most of them are integrated and cannot be disassembled into smaller parts, making them inconvenient to transport. Utility Model Content
