The probe is positioned correspondingly to the positioning block. Rotating the threaded rod causes the sliding block, baffle, and telescopic rod to move synchronously, ensuring the positioning block levels the probe's through-hole. Reversing the threaded rod and retracting the rod retracts the positioning block, guaranteeing that the probe's through-hole remains horizontal with the wind direction after the anemometer is installed, thereby improving testing accuracy.
