A multi-blade top awning includes an awning frame. A blade top plate, a linkage strip for driving the blade top plate to be opened/closed and a driving mechanism are cooperatively mounted on the awning frame. The driving mechanism includes a connection rod, a rocker arm, a worm and gear assembly and a power source. The connection rod is used for driving the linkage strip to move, the rocker arm is used for driving the connection rod to move, the worm and gear assembly is used for driving the rocker arm to rotate, and the power source is used for providing power for the worm and gear assembly. The rocker arm can rotate by 360 degrees around the worm and gear assembly, such that the blade top plate is opened/closed, a manual rocker does not need to be rotated in a reverse direction when the blade top plate is closed.
