Compared with the prior art, the invention has the beneficial effects that:

1. the staff holds the holding rod and presses button switch through the thumb, when the measuring part is just to the time with the wind direction, the ventilation volume in the ventilation hole on two aviation baffles is the same for two aviation baffles atress are balanced, thereby the steering spindle keeps relative quiescent condition, thereby electrically conductive roller leads to the circuit to switch on with electrically conductive piece contact, and the pilot lamp is in the state of often brightening this moment, is used for reminding the staff that the wind speed data that this moment surveyed is accurate relatively.

2. When the measuring part is not aligned with the wind direction, the ventilation quantity of the ventilation holes on the two air deflectors is changed in a reaction mode, the stress of the two air deflectors is different in size, so that the steering shaft is driven to be attached to the guide roller to deflect towards the air deflector on the side with larger stress, the conductive roller is made to be in contact with the insulating part, the circuit is in a disconnected state, and the indicating lamp is in a closed state at the moment and used for reminding a worker to adjust the orientation angle of the measuring part.

3. When the wind direction is unstable, the ventilation quantity of the ventilation holes in the two air deflectors is changed continuously, so that the two air deflectors are stressed unstably, the steering of the steering shaft becomes unstable, the conductive roller rolls back and forth between the two insulating parts and repeatedly contacts the conductive parts, and the indicator light is in a flashing state at the moment and is used for reminding a worker that the wind direction is unstable at the moment and not suitable for wind speed measurement.
