[0031] The utility model comprises the following steps during use:

[0032] Preparation stage:

[0033] Make sure both the tractor and the helicopter are in a safe state, the tractor's engine is turned off, the helicopter's power system is also turned off, and check the integrity of the towing hook and towing ring to ensure there is no damage or wear.

[0034] Connect the towing eye:

[0035] Position the towing vehicle in a suitable position in front of the helicopter and connect the towing eye to the towing device of the towing vehicle. Typically, this involves sliding the towing eye into the hook or connection point on the towing vehicle and ensuring it is locked.

[0036] Connect the towing hook:

[0037] The operator walks to the helicopter's towing point, aligns the towing hook with the helicopter's towing point, and then inserts or hooks the towing point to confirm that the towing hook is securely locked on the helicopter's towing point.

[0038] Start traction:

[0039] The operator returns to the tractor, starts the engine, and drives the tractor slowly. The tractor transfers force to the towing hook through the towing ring, thereby starting to pull the helicopter. During the entire towing process, the operator should continue to monitor the status of the helicopter to ensure its smooth movement.

[0040] Monitoring and Adjustment:

[0041] If the helicopter deviates from the planned path during movement, the operator should stop the helicopter immediately and make adjustments, check the connection status of the towing hook and towing ring, and readjust if necessary to ensure safety.

[0042] Arrival at destination:

[0043] When the helicopter is towed to the designated location, the operator should stop the helicopter slowly, turn off the engine of the towing vehicle, confirm that the helicopter is parked safely, and unload the towing hook and towing ring: unlock and remove the towing ring, remove it from the towing vehicle, unlock and remove the towing hook, and remove it from the towing point of the helicopter.

[0044] Inspection and storage:

[0045] Check the towing hook and towing ring to confirm that there is no damage, and store the towing hook and towing ring safely in the designated location for next use.

[0046] Before connecting the towing ring and the towing hook, check whether the hand handle 6 and the front handle are firm and easy to operate. Use the hand handle 6 to adjust the height of the towing rod to ensure that the towing ring is aligned with the connection point of the towing vehicle. Adjust the position of the front handle to better control the angle of the towing rod so that the towing hook can easily contact and lock to the towing point of the helicopter. During the towing process, if you need to fine-tune the direction or angle of the towing rod, you can use the hand handle 6 and the front handle to adjust it. When towing the helicopter, continue to use the hand handle 6 and the front handle to make fine adjustments to ensure that the helicopter moves smoothly along the predetermined path. Use the hand handle 6 and the front handle to fine-tune the position of the towing rod so that you can safely park the helicopter when you reach the destination. Use the hand handle 6 and the front handle to adjust the position of the towing rod so that it is easier to unlock and remove the towing hook and towing ring.

[0047] The utility model forms a stable and flexible traction system through the combination of the connecting rod 1, the main rod 2, the buffer device 3 and the wheel fork 4, which can effectively tow the unmanned helicopter without causing rigid impact on its landing gear.
