[0026] Embodiment 2:
[0027] Figures 1-6A hoisting auxiliary device for laser cutting of steel members showing an embodiment of the present utility model, which includes: an arc-shaped limiting member 1: a first bent fixing member 2 is rotatably connected to the upper side of the inner cavity of the arc-shaped limiting member 1, and a second bent fixing member 3 is rotatably connected to the lower side of the inner cavity of the arc-shaped limiting member 1. The left end of the second bent fixing member 3 is rotatably connected to a sleeve 4, and the left end of the first bent fixing member 2 is rotatably connected to a connecting rod 5. The bottom end of the connecting rod 5 penetrates into the inner cavity of the sleeve 4 and is fixedly connected to a round head 6. A spring 7 is welded between the top end of the round head 6 and the inner wall of the sleeve 4. A bolt 14 is commonly threadedly connected to the inner cavities of the hollow head 12 and the hollow limiting head 13. A cushion ring 15 is sleeved on the surface of the bolt 14. Through the arrangement of the cushion ring 15, the contact surface between the bolt 14 and the hollow limiting head 13 can be cushioned and protected, and a tightening force is obtained between the bolt 14 and the hollow limiting head 13, which can make the bolt 14 and the hollow limiting head 13 more fixed.

[0028] Working principle: When the present utility model is in use, the user sleeved the first half-ring limiting member 8 and the second half-ring limiting member 9 on the surface of the steel, then relatively deflected the first half-ring limiting member 8 and the second half-ring limiting member 9, and then relatively rotated the first bent fixing member 2 and the second bent fixing member 3.
