Embodiment 1
[0033] refer to Figure 1-12 As shown, this embodiment is a new type of quick self-decoupling device, which includes a column sleeve 1, a solid cylinder 3, a lifting claw 2, a lifting lug 4 and a positioning pin 5. The inside of the column sleeve 1 is provided with a cavity for the vertical displacement of the solid column 3, the upper center of the solid column 3 is fixed with a lifting lug 4, and the upper periphery of the solid column 3 is uniformly provided with a gap, and the gap is along the horizontal direction. A positioning pin 5 is fixed, and the outer side of the positioning pin 5 is provided with a hanging claw 2 that can rotate along a vertical plane.
[0034] In this embodiment, the column cover 1 is fixed on the hoisting object 7, such as by welding. The column cover 1 is a quadrangular prism, and the corresponding solid column 3 is a quadrangular prism. The lifting lug 4 is detachably connected to the solid cylinder 3 by means of screw connection.

Embodiment 2
[0038] The structure and application of this embodiment are basically the same as those of Embodiment 1, the difference is that the column sleeve 1 is a cylindrical sleeve, and the solid cylinder 3 is a cylinder with notches on its periphery.
Embodiment 3
[0040] The structure and application of this embodiment are basically the same as those of the second embodiment. The column sleeve 1 is a cylindrical sleeve, and the solid cylinder 3 is a cylinder with notches on its periphery. Considering that the cylinder is easy to rotate, an anti-rotation convex key is provided in the inner cavity wall of the cylinder sleeve, and an anti-rotation key groove is provided on the outer wall of the cylinder.
