The traditional hand-held fan has a fixed shape, the length cannot be adjusted, and the hand-held distance is limited. The volume is too large to be convenient for storage and carrying. The blowing angle is single, making it difficult to flexibly adjust the air supply direction. Most products on the market only pay attention to the blowing function and lack delicate texture. This telescopic hand-held fan, with the telescopic connecting rod structure as the core, takes into account the freedom of air supply, portable storage and exquisite texture, and is suitable for outdoor travel, home and office use.
