The invention particularly relates to a rotary lifting type adjustable lifting lug structure and a using method. The lifting lug structure comprises a fixed side supporting wall, a first limiting mechanism, a rotary side supporting wall, a lifting rod, a second limiting mechanism and a connecting mechanism. The number of the fixed side supporting walls is two, grooves are formed in the two adjacent edges of the two fixed side supporting walls, first limiting mechanisms are arranged on the sides, away from the grooves, of the inner walls of the two fixed side supporting walls, rotating side supporting walls are arranged on the sides, close to the grooves, of the inner walls of the two fixed side supporting walls, and the bottom faces of the rotating side supporting walls make contact with the first limiting mechanisms. The bottom faces of the rotating side supporting walls are smooth curved faces, the faces, making contact with the bottom faces of the rotating side supporting walls, of the first limiting mechanisms are planes, the rotating side supporting walls are connected to the fixed side supporting walls through the connecting mechanisms, and the lifting rod penetrates through the two rotating side supporting walls and is connected with grooves in the fixed side supporting walls in a matched mode. And a second limiting mechanism is arranged on the hoisting rod.
