[0026] Working Principle: This utility model places the mounting frame 2 and the fixing plate 3 at both ends of the fan body 1, inserts the mounting bolts 4 into both ends of the mounting frame 2 and the fixing plate 3, and achieves a stable connection between the mounting frame 2 and the fixing plate 3 by tightening the knob 5. The mounting block 7 is then stably connected to the mounting bolts 4 by manually rotating the threaded mounting seat 6. This facilitates the quick installation of the fan body 1. The first motor 12 drives the first one-way screw 13 to rotate, which in turn moves the threaded slider 10. The slider 10 simultaneously moves the first sliding frame 9 horizontally, and the first sliding frame 9 simultaneously moves the mounting frame 14. This allows for convenient and rapid installation of the fan body 1. The distance between the mounting bracket 14 and the air outlet of the fan body 1 is adjusted by the operation of the second motor 20. The second motor 20 drives the second one-way screw 15 to rotate, which in turn drives the pulley 17 to rotate.
