[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, lift the pressure plate upwards so that the telescopic rod pulls the elastic part in the fixed rod. When the plug plate leaves the slot, rotate the pressure plate so that the fixed rod drives the movable ring to rotate outside the adapter block. When the pressure plate is not above the cover plate and the movable plate, lift the cover plate upwards so that the movable block on one side of the cover plate rotates and moves along the movable groove. At the same time, the connecting plate on one side of the cover plate will rotate in the connecting groove, so as to achieve a state where the cover plate and the movable plate are folded and turned. At this time, the internal structure of the main body of the fresh air device is exposed, and it can be inspected and maintained. The cooperation of multiple devices makes it easier for workers to quickly switch on and off the main body of the fresh air device, reduces the loading and unloading steps, and improves the maintenance efficiency.
