[0002] Unmanned aerial vehicles are equipped with autopilots, program control devices and other equipment. Personnel on the ground, on ships or at the mother aircraft remote control station use radar and other equipment to track, locate, remotely control, telemeter and digitally transmit the drones. Compared with manned aircraft, drones have the advantages of small size, low cost, easy use, low requirements for the combat environment and strong battlefield survivability.

[0003] Some drones need to be installed with landing gear to protect the drone body structure and enable the drone to land smoothly. However, in the prior art, the welding of drone landing gear requires fixing two separate workpieces on a fixing mechanism in turn, and only the upper part of the workpiece can be welded. The side that is close to the fixed bed needs to be disassembled again before fixed welding. However, the drone landing gear is usually composed of four workpieces, and the steps of fixing, welding, and disassembly need to be repeated many times. Therefore, it takes a long time to weld the landing gear, which cannot meet the needs of fast welding. Therefore, a multi-angle welding device for a drone shell is proposed. Summary of the invention
