Background With the development of economic technology, fans are increasingly widely used. When the wind speed of the area where the fan is located changes, the attack angle is changed by twisting the blade, so that aerodynamic force is changed, and the blade load is effectively controlled. However, when the blades of the fan are too large, due to the fact that the fan is heavy in structure, large in inertia and slow in response, when strong wind is encountered suddenly, the condition that the blade load exceeds the limit and even the blades are damaged easily occurs due to too slow adjustment of the blade angle response, and therefore the control safety of the fan is low. It should be noted that the foregoing is only for aiding in understanding the technical problem solved by the present invention, and is not an admission that the foregoing is prior art.
