Correspondingly, the top end of the universal joint is provided with a connecting part which is installed in a rotating fit with the first connecting piece, and the connecting part is in a columnar structure with an annular groove with reference to the second installation column 322, which is not described herein. The technique of rotatably mounting the universal joint in the mounting groove is not particularly limited, and may be any technique known in the art.

The structure of the universal joint can adopt a single universal joint or a universal joint with a fixing frame.

In other embodiments, referring to fig. 17, the fan base 30 includes a first base 31, a second base 33, and a second connecting member 32. The first base 31 and the second base 33 are movably connected by a second connecting piece 32.

The first base 31 has two mounting positions, and a fan body 20 is mounted on both mounting positions through a fan mounting frame 10. The two fan mounting frames 10 are respectively rotatably mounted on the corresponding mounting positions. Correspondingly, the mounting position is provided with a connecting part which is mounted in a rotating fit with the first connecting piece, and the connecting part is in a columnar structure with an annular groove with reference to the second mounting column 322, which is not described herein.

The second connector 32 is a universal joint with a metal sizing hose. In the installation, the top end of the universal joint with the metal shaping hose is rotatably connected to the bottom of the first base 31, and the bottom end of the universal joint with the metal shaping hose is rotatably connected to the top of the second base 33. It will be appreciated that "metal sizing hose" is a common technical name in the art and is not limited to its degree of softness.

In general, a circuit board (not shown in the drawings) is disposed in the fan base 30, so in each of the above embodiments, the fan mounting frame 10 and the interior of the fan base 30 should be communicated, and a space for a wire to pass through is provided, so that the wire can pass into the fan housing 21 to electrically connect the circuit board and the blower assembly 22, thereby achieving the blower switch control. This is also prior art.
