The air expansion port 205 is funnel-shaped, and the opening is larger than the pipe diameter, so that the generated wind can be transmitted to the surroundings faster. At the same time, the vibration test box 201 detects the vibration frequency of the started fan body 202, thereby detecting the stability of the fan body 202.

[0025] like Figure 2-4As shown, the first rotating assembly 3 includes a motor 301 installed on the inner wall of the bottom end of the operating box 1, the output end of the motor 301 is rotatably connected to the limiting rod 302, the upper end of the limiting rod 302 is provided with a rotating rod 303, the rotating rod 303 is fixedly connected to the output end of the motor 301, the first rotating assembly 3 also includes a first sliding rod 304 fixedly connected to the top left side of the rotating rod 303, the inner wall at the center of the limiting rod 302 is fixedly connected to a rotating rod 305, the bottom end of the rotating rod 305 passes through the bottom outer wall of the limiting rod 302 and is fixedly connected to a shaft sleeve 306, the right side of the limiting rod 302 is fixedly connected to a second sliding rod 307, the bottom end of the second sliding rod 307 is fixedly connected to the inner wall of the bottom end of the operating box 1, and the second rotating assembly 4 includes The sector gear 401 is rotatably connected to the outer wall of the top end of the rotating rod 305, and the outer wall of the right end of the sector gear 401 is meshed with a bar gear ring 402.
