The provision of the support block provides a force point for the second motor, making its operation more stable. The provision of the sliding block and the sliding groove can support the support block and prevent it from affecting the overall rotation of the two water spraying pipes and the shunt pipe.

[0009] Preferably, the top end of the first rotating shaft is rotatably connected with a second communicating pipe, and the top end of the outer wall of the second communicating pipe is fixedly connected with a flange, so as to facilitate the connection with a water tank on the helicopter.

[0010] Compared with the prior art, the helicopter main spray pipe angle adjusting device has the following advantages and positive effects:

[0011] In the helicopter main spray pipe angle adjusting device, the rotation of the first motor drives the second gear to rotate, thereby driving the first gear connected with the second gear to rotate, driving the first rotating shaft to rotate, and driving the first communicating pipe, the shunt pipe and the two water spraying pipes to rotate horizontally as a whole, so that the angle is adjusted.
