description The invention discloses a shackle for lifting round objects, comprising lifting rings, supporting plates, screw rods, two clamp rings and two movable moment arms, wherein, one clamp ring and one movable moment arm are fixedly connected with each other to form a hook body, the two hook bodies are correspondingly and rotatablely connected with each other by the screw rods on the two movable moment arms and are in symmetrical distribution, the lifting rings are respectively and fixedly connected with the upper parts of the two movable moment arms, the supporting plates are installed on the clamp rings, and the screw rods are arranged at the middle-lower part of the movable moment arms. The four supporting plates are arranged and provided with skidproof sleeves which are rubber sleeves, so that friction force can be increased for skid prevention, and the rubber material is beneficial to preventing metal objects from being scratched. The invention is simple in structure, effective and practical, can be convenientl
