[0024] Specifically, when in use, by placing the mounting arc plate 3 on one side of the upper end of the first air inlet duct 1, the mounting plate 4 will fit with the side wall of the first air inlet duct 1, and then rotating the bolts 5 to complete the fixing of the mounting plate 4 and the first air inlet duct 1. At this time, the mounting arc plate 3 connected to the mounting plate 4 will also be fixed.
