Ejection device for shaping cantilever formwork

The utility model belongs to the technical field of water conservancy and hydropower engineering construction, and provides an ejection device for a shaping cantilever formwork. The ejection device for the shaping cantilever formwork is used for keeping the shaping cantilever formwork to be stable when the formwork is erected at a curved surface position. A round head is arranged in a square box, and the front end of a screw rod matched with a nut extends into the square box to be integrally connected with the round head. The ejection device can ensure that curved surface formwork erecting is stable, is high in universality, greatly saves material input and labor input, and also shortens formwork erecting time.
