[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0025] Example: Figure 1-4 As shown, the utility model provides a technical solution, a sling for construction, including a sling top base 1, a rotating ring 3 is provided inside the sling top base 1, a cylinder 2 is welded to the bottom of the rotating ring 3, spring dampers 4 are welded to both ends of the cylinder 2, the tops of the two spring dampers 4 are connected by a hook 5, the hook 5 and the rotating ring 3 are connected by an adjustable telescopic rod 6, and connecting ropes 7 are provided at both ends of the top of the hook 5, and the connecting ropes 7 are fixedly installed on the bottom surface of the rotating ring 3;

[0026] A spring telescopic rod 9 is installed at one end of the top of the cylinder 2 by screws, and a clamping block 10 is installed at one end of the spring telescopic rod 9 by screws. The tooth groove 8 is engaged with the clamping block 10 to facilitate the connection and fixation of the sling top seat 1 and the rotating ring 3. The bottom of the sling top seat 1 is evenly provided with tooth grooves 8;

[0027] Both ends of the bottom of the hook 5 are welded with a moving rod 11, and a spring telescopic column 12 is provided on the outside of the moving rod 11. A connecting frame 13 is installed on the bottom surface of the spring telescopic column 12 by screws. An extrusion plate 14 is welded to one end of the connecting frame 13. The longitudinal section of the extrusion plate 14 is arc-shaped. The extrusion plate 14 fits with the arc end of the hook 5 to ensure the stability of the movement of the extrusion plate 14 and facilitate pressing of objects. A rubber plate 15 is bonded to the bottom surface of the extrusion plate 14;

[0028] The spring telescopic column 12 includes a fixed cylinder 1201, a return spring 1202 and a movable column 1203;

[0029] Fixed cylinders 1201 are welded to both ends of the inner bottom surface of the cylinder 2, a return spring 1202 is welded to the inner top surface of the fixed cylinder 1201, and a moving column 1203 is welded to the bottom surface of the return spring 1202. The bottom surface of the moving column 1203 is connected to the connecting frame 13 by screws, and the top of the moving column 1203 is connected to the moving rod 11 by screws, so as to drive the moving rod 11 to move, thereby driving the connecting frame 13 to move. The moving column 1203 is slidably connected to the inside of the fixed cylinder 1201.
