[0002] Die steel is a steel type used to manufacture cold stamping dies, hot forging dies, die-casting dies and other dies. During the production and manufacturing process of die steel, heat treatment is required. At this time, a sling is needed to lift the die steel. After retrieval, a heat treatment in-and-out furnace sling for die steel is recorded in the Chinese patent application with the application number CN202321478175.4. In this patent, a bidirectional screw is designed to drive the clamping plate to move, so that the die steel can be firmly clamped.

[0003] However, there are still certain deficiencies in the above patent during actual use. First, although the position of the clamping seat can be adjusted to adapt to different spacing requirements, the overall sling is unbalanced after adjustment and is prone to shaking. Second, the disc-shaped support plate is not convenient for supporting the heat treatment of multiple die steels, and the efficiency is limited. Therefore, it is necessary to design a new sling to solve this problem. Summary of the Utility Model

Bottom plates 600 are fixed to the bottoms of both ends of the rectangular top plate 100. A fixed rod 300 is fixed between the two bottom plates 600. Eight groups of clamping assemblies 400 are arranged on the fixed rod 300. The number of the clamping assemblies 400 can be increased according to requirements. The clamping assemblies 400 can clamp the die steel. The clamping assembly 400 includes a fixed clamping plate 401, a movable clamping plate 402, a threaded rod 403, and a threaded knob 404. The fixed clamping plate 401 is fixed on the fixed rod 300. The movable clamping plate 402 is arranged opposite to the fixed clamping plate 401 and is slidably connected to the surface of the fixed rod 300 and can slide along the fixed rod 300. A rectangular groove 200 is formed on the surface of the rectangular top plate 100. The tops of the fixed clamping plate 401 and the movable clamping plate 402 extend out of the rectangular groove 200.
