In a preferred scheme, each positioning mechanism is arranged on the upper side surface of the supporting arm. The contact surface between the bracket arm and the vane is designated as an upper side surface.

In the preferred scheme, a stop block is arranged in a sliding groove of the supporting arm. By arranging the stop block, the opening angle of the window leaf can be effectively limited.

In a preferable scheme, the rear end of the supporting arm is provided with a supporting arm blocking piece corresponding to the shape of the rear end of the supporting arm. Through setting up the trailing arm separation blade, the trailing arm separation blade can be injectd the trailing arm position, makes the trailing arm can only rotate along one side of support arm, makes the one-way opening and closing of casement, guarantees the leakproofness of window.

The beneficial effects of the utility model reside in that: the window hinge is simple in structure, is directly matched with the window leaf through the positioning salient points, is convenient to install, and can effectively save installation time and improve working efficiency.
