[0015] 1. This utility model allows for the carrying of docking components of different specifications during the use of the device. When assembling docking ends of different specifications, the device performs matching docking, causing multiple mating plates on the side of the corresponding docking ring gauge to align with the mating groove. After mating, the docking ring gauge is rotated to align docking holes one and two. Once aligned, the limiting bolts are installed into docking holes one and two, locking the docking ring gauge to the side of the axial flow fan device body. Then, the mating end is installed into the other end of the docking ring rail. When docking is complete, multiple locking bolts on the side pass through the interior of the docking ring rail and abut against the docking end, locking it. This eliminates the need for multiple fan conversions when adapting docking ends of different specifications, reducing installation difficulty.

[0016] 2. In the process of using the device, the motor inside the drive assembly is started, causing the drive shaft fixed at its output end to rotate. When the drive shaft rotates, it drives the drive track meshing on its side, which in turn drives the driven shaft at the other end of its inner side. When the driven shaft rotates, the drive column fixed on its side rotates, driving the rotating shaft at its end, which in turn drives the transmission blades fixed on its side to rotate, thus making the fan work.
