In this case, it is difficult to free our other hands to hold a fan and blow air to cool down, so there is a strict restriction on holding an umbrella and using a personal fan at the same time. In response to this situation, the Chinese utility model with the authorization publication number CN212615467U discloses a technical solution of "electric fan applied to umbrella", which allows a personal fan to be clamped on the center pole of the umbrella, which does not require the use of hands and to some extent solves the above-mentioned shortcomings in use.

[0004] However, this technical solution is prone to the phenomenon of the cover plate bursting or the clamping part swinging and displacing during implementation. Because the outer diameters of different types of rods are often different, when used with a rod with a large outer diameter, the cover plate will burst due to the interference fit, but when used with a rod with a small outer diameter, the clamping part will swing and displace or cannot be clamped normally due to the inability to clamp, which seriously weakens the use effect and applicability of the technical solution.
