In some embodiments, referring to fig. 2 and 5, a plurality of fixtures 2 are provided at a first side of the fan base 1, i.e., the fixtures 2 are provided at a bottom of the fan base 1. A plurality of fan blades 3 are arranged on the second side of the fan base 1, i.e. the fan blades 3 are arranged on top of the fan base 1. The fan base 1 is provided with a plurality of mounting holes along the circumferential direction at intervals, and a plurality of fixing pieces 2 are arranged at the plurality of mounting holes in a one-to-one correspondence manner and fixedly connected with a plurality of fan blades 3 in a one-to-one correspondence manner through the mounting holes, so that synchronous rotation between the fixing pieces 2 and the fan blades 3 is realized.

In some embodiments, a gasket 7 is further disposed between the fixing piece 2 and the fan blade 3, a part of the gasket 7 is located at the outer edge of the mounting hole, and another part of the gasket 7 extends into the mounting hole, so that a certain anti-abrasion effect is achieved on the fan base 1 in the process of rotating the fixing piece 2 and the fan blade 3 relative to the fan base 1, the structure that the fixing piece 2 and the fan blade 3 continuously scratch or collide with the fan base 1 close to the mounting hole during rotation is avoided, and the gasket 7 can be supported between the fixing piece 2 and the fan blade 3, so that the stability of the rotation process of the fixing piece 2 and the fan blade 3 is improved to a certain extent.

Specifically, the plurality of links 4 are all disposed on the first side of the fan base 1, i.e., the links 4 are disposed at the bottom of the fan base 1.

In the actual assembly process, the connecting piece can be a screw, a rivet or a pin, for example, when the connecting piece adopts the screw, the screw sequentially passes through the second connecting hole and the first connecting hole so as to realize effective assembly between the fixing piece 2 and the connecting rod 4 and ensure synchronous rotation among a plurality of fixing pieces 2.

It should be noted that, in the actual application process, the connection between the fixing element 2 and the connecting rod 4 may be set to have a certain clearance, that is, a certain play allowance may exist between the fixing element 2 and the connecting rod 4. For example, the diameters of the selected screws may be slightly smaller than the diameters of the first connecting hole and the second connecting hole, and the first connecting hole and/or the second connecting hole may be provided as a strip-shaped special-shaped hole, so that a certain activity allowance exists between the fixing piece 2 and the connecting rod 4. When a plurality of fixing pieces 2 rotate, the condition that the connecting rod 4 is broken and the like due to the fact that the tearing force or the extrusion force applied to the connecting rod 4 between every two adjacent fixing pieces 2 is overlarge is avoided.
