The main function of the linkage assembly 3 is to realize the opening and closing of the clamping assembly 2 through mechanical linkage, thereby completing the clamping and releasing of the winding. The whole process is simple to operate, convenient to use, and high in working efficiency.

[0029] The linkage assembly 3 is of a symmetrical structure, which comprises first linkages 31 arranged on both sides of the lifting ring 1 respectively, second linkages 32 arranged at the ends of the first linkages 31 correspondingly, and third linkages 33 arranged at the connecting points of the two second linkages 32. The clamping assembly 2 is arranged directly below the third linkages 33. The symmetrical structure design can ensure the uniform distribution of the clamping force, and improve the stability and safety in the hoisting process.

[0030] Meanwhile, a force receiving rod 34 is arranged between the two first linkages 31. One end of the force receiving rod 34 is rotatably connected to the connecting point between the first linkage 31 and the second linkage 32, and the other end is abutted with the side surface of the lifting ring 1 and extends outward. The main function of the force receiving rod 34 is to transmit the pulling force of the lifting equipment (such as a crane, a hoist, etc.) to the linkage assembly 3, and at the same time, the force receiving rod 34 plays a role in balancing and stabilizing, preventing the swinging caused by external force in the hoisting process.

[0031] In the embodiment, the two ends of the third linkage 33 are respectively provided with limit rods 35, and the whole is in the shape of “M”. The inner side of the limit rod 35 is provided with the clamping assembly 2. The limit rod 35 can limit the movement range of the clamping assembly 2, effectively prevent the clamping assembly 2 from moving excessively in the hoisting process, ensure the accuracy and reliability of the clamping action, and also avoid the winding from falling off due to accidental loosening of the clamping assembly 2.

[0032] In the embodiment, the first linkage 31 and the second linkage 32 are in the shape of a rhombus.

[0035] In the embodiment, the first connecting rod 31, the second connecting rod 32 and the fifth connecting rod 23 are preferably double-layer structures, i.e., multiple single rods are combined, thereby prolonging service life and further guaranteeing stability and safety of the tool.

[0036] In the embodiment, the second connecting rod 32 and the fourth connecting rod 21 are both in the shape of "L", the "L" shape can amplify clamping force through the principle of lever, improve clamping effect, and better fit the shape of the winding, thereby adapting to windings of different sizes and shapes.

[0037] Of course, the outer diameter surface of the clamping piece 22 is adapted to the inner diameter surface of the winding and can be arc-shaped, thereby guaranteeing uniform force on the winding and preventing the problem of one end being high and the other end being low, and guaranteeing stability and firmness of the winding.

[0038] In addition, the tool is pulled upward by hanging the lifting ring 1 by a crane or other equipment, at this time, the force bar 34 is blocked by the lifting ring 1, thereby providing a downward force, the angle between the first connecting rod 31 and the second connecting rod 32 is gradually reduced, then the fourth connecting rod 21 is respectively opened outward, i.e., the clamping piece 22 is opened outward to clamp the inner diameter surface of the winding, the whole process is simple in operation and convenient to use.
