The above-mentioned scheme solves the problem of shaft hole rupture of the fan during equipment operation. It can be understood that the above-mentioned scheme can be applied to the fan connecting shaft during use. The motor shaft is connected with the mounting hole 109 in the mounting column 107 through the opening 108. For example, a hexagonal bolt can be used to fasten through the mounting hole 109, ensuring the stable connection of the motor shaft and the mounting column 107. When the motor starts to operate, the fan blade 103 starts to rotate under the driving of the motor. Due to the arrangement of the reinforcing plate 105, the connection strength between the mounting column 107 and the outer shell 101 is greatly enhanced, effectively resisting the impact force when the motor starts, avoiding the occurrence of shaft hole rupture. At the same time, the extension plate 104 further enhances the stability of the structure, the chamfer groove 106 reduces the stress concentration at the reinforcing plate 105, and the reliability of the whole shaft hole reinforcing shaft hole structure during long-time operation is ensured. Thus, the problem of shaft hole rupture of the fan during equipment operation is actively and effectively solved while the original beneficial effects are retained.
