[0002] The helicopter tail rotor is a very important structure of the helicopter. When the existing helicopter tail rotor encounters strong winds, the main rotor blades on the helicopter are prone to swaying in the wind, reducing its stability and easily causing damage to the main rotor blades. Therefore, a helicopter tail rotor tip mooring device is needed for protection. Traditional mooring devices have general adaptability and poor adjustment capabilities, and cannot be adjusted for helicopter tail rotors of different sizes.

Although the tail rotor can also be reliably moored, the adaptability is general and the adjustment ability is poor, and it cannot be adjusted for helicopter tail rotors of different sizes.

The outer periphery of the winding rod is connected to a fixing clamp for fixing the pull rope.

[0010] As a preferred embodiment, the end of the adjusting threaded rod close to the adjusting plate is constructed in a hemispherical shape.

[0011] As a preferred embodiment, a connecting plate is welded to the inner wall of the blocking frame.

[0012] As a preferred embodiment, the outer periphery of the connecting rod is tied with a binding rope for facilitating the subsequent fixing of the unfolded waterproof cloth cover.
