Compared with the prior art, the utility model has the beneficial effects that:

1. The elastic limiting mechanism is arranged at the bottom of the side edge of the frame, when the support rod pulls the louver awning to correspond to the rear section of the closing process of the window hole, the abutting piece on the elastic limiting mechanism is pushed by the support rod to rotate and compress the torsion spring, and after the louver awning is closed, the elastic limiting mechanism provides elastic acting force between the louver awning and the support rod, so that looseness of the hinge joint between the louver awning and the support rod is reduced, and the louver awning is kept stable after being closed;

2. When the support rod pushes the louver awning to open, the elastic limiting mechanism also provides a pushing force for the hinged overturning structures of the support rod and the louver awning to open more smoothly;

3. The elastic limiting mechanism can also avoid the problem that dead angles in the connecting rod mechanism occur between the She Zheyang awning and the supporting rod.
