Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a compact fan, including: a connecting base 1, and a first shock-absorbing pad 2 disposed on the upper side of the connecting base 1, a first positioning block 3 disposed on the inner side of the first shock-absorbing pad 2, and an organic shell 4 disposed on the upper side of the first positioning block 3, and further including:

[0029] The second shock-absorbing pad 5 is installed at the lower end of the housing 4, and the connecting component 6 is provided on the left side of the housing 4.

[0030] like Figure 4 , Figure 5 and Figure 6As shown, the connecting assembly 6 includes an operating lever 601 installed on the left side of the housing 4, with a locking lever 602 on the upper side of the operating lever 601. A connecting block 603 is connected to the right side of the operating lever 601, and a first guide strip 604 is provided on the outer side of the connecting block 603. The operating lever 601 is rotatably mounted relative to the housing 4, and the locking lever 602 is engaged with both the operating lever 601 and the housing 4. The operating lever 601 and the connecting block 603 are threadedly connected, and the connecting block 603 is engaged with the connecting base 1.
