The invention discloses a two-state dual-driving four-lever quick positioning mechanism. The positioning mechanism comprises a hinge four-lever mechanism formed by linking four link levers with the same length through four hinges, wherein one hinge is a fixed hinge (A), the other three hinges are moved hinges (B, C, D); assistant fixed hinges (F, E) are respectively arranged beside two moved hinges (B, D) adjacent to the fixed hinge (A); levers to connect the assistant fixed hinges (F, E) with the moved hinges (B, D) are assistant moved levers (BF, DE); the assistant moved levers (BF, DE) moves through an oil cylinder or an air cylinder. According to the four-linkage mechanism, the positioning mechanism can quickly realize the position of four square top points on the plane; the positioning mechanism is simple in structure, low in cost, high in efficiency and fast in operation speed.
