The invention discloses a cylindrical workpiece hoisting tool. The cylindrical workpiece hoisting tool comprises a suspension ring, a rhombic hinge, pulling plates and a clamping plate, and the rhombic hinge, the pulling plates and the clamping plate are orderly fixed to the lower end of the suspension ring. An extension spring is arranged in a horizontal diagonal line in the rhombic hinge. The clamping plate comprises two symmetrical semicircular tubular structures respectively connected to the pulling plates 4. Rubber gaskets are inlaid in the inner wall of the clamping plate. The rhombic hinge comprises four cast steel supports combined by screws and four connection points of the rhombic hinge can rotate. The cylindrical workpiece hoisting tool utilizes a clamping hoisting method, in hoisting, the clamping plate is stretched only by manual operation and then clamps a workpiece so that operation is simple and convenient, in hoisting, under the action of workpiece gravity, the cylindrical workpiece hoisting tool can automatically clamp the workpiece and the rubber gaskets can improve friction so that hoisting reliability is improved.
