A hand-push rotating umbrella comprises extension springs at one side of the supporting ribs where an upward acting force can be produced by means of the pretension force of the extension spring when the moveable runner is pushed up so that the moveable runner and upper rib supporting rods would not fall down affected by gravity, thus a stable umbrella closing state able to be achieved without providing the engagement structure and solving the problems of the existing reversely-folded umbrella produced by only able to stably close the umbrella by using the engagement structure. Moreover, through the collocation application of the upper runner and moveable runner in the present invention, the umbrella canopy would rotate to offset the impact force caused by the wind resistance or collision in the case of strong wind or umbrella rib collision with some foreign object or person, thus able to avoid stabbing and hurting other people and improve the umbrella use safety. 1. A hand-push rotating umbrella , comprising;{'b': 1', '2', '1', '3', '1', '4', '3', '2', '5', '4', '6', '3', '7', '6', '8', '7', '4', '9', '6', '8', '10', '6', '7', '20', '8', '5', '9', '1', '132, 'an umbrella shaft (), a handle () disposed at a bottom of the umbrella shaft (), an upper runner () disposed at a top of the umbrella shaft (), a moveable runner () disposed between the upper runner () and handle (), a middle runner () disposed at a top of the moveable runner () plurality of upper rib supporting rods () pivotally jointed at a periphery of the upper runner (), a reversely-folded rib supporting rod () pivotally jointed with one end of the upper rib supporting rods (), lower rib supporting rods () having one end thereof pivotally jointed with the reversely-folded rib supporting rod () and having another end thereof pivotally jointed with the moveable runner (), moveable brace rods () having one end thereof pivotally jointed with the upper rib supporting rods () and having another end thereof ...
