Tower fans generally include a base, a swing base fixed on the base, and a machine body connected with the swing base. Since the base is relatively large, the machine body and the base are usually designed separately when the product is designed, so the user needs to install the base himself.

[0003] For example, Chinese Patent No. CN216691561U discloses a tower fan base, which includes a base shell divided into a first base shell and a second base shell. The upper surface of the first base shell is provided with a first recess for increasing the contact area with the swing base. The upper surface of the second base shell is provided with a second recess for increasing the contact area with the swing base. The connecting part between the first base shell and the second base shell is provided with a clamping part and a mounting cavity, respectively. The clamping part is clamped in or separated from the mounting cavity. The first base shell and the second base shell can be installed or separated. In addition, the first base shell and the second base shell can be easily packaged and replaced after being separated.

[0004] However, the above-mentioned technology still has defects. The second recess of the base shell is also provided with a second screw hole, so that the base shell and the bottom surface of the swing base are connected by screws.
