Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) traction, in particular to a UAV traction device. Background Art

[0002] The drone towing bar is mainly used to tow the drone on and off the runway and for short-distance movement in flat areas such as aprons and hangars. The towing bar can be towed by a vehicle with a towing hook or by manpower.

[0003] Existing towing rod structures mostly use a whole metal rod. When dealing with towing holes at different heights, the inclination angle between the towing rod and the ground is adjusted. This makes one end of the towing rod higher than the other end, resulting in one end of the towing rod being able to adapt to the towing hole of the drone but not the towing hole of the towing vehicle.
