There are at least four groups of latches 13 and hanging grooves 12, and the first upper frame 1-1, the second upper frame 1-2 or the lower frame 2 are displaced along the vertical axis so that the latch 13 is gradually disengaged or embedded relative to the hanging groove 12 in a predetermined movement path, thereby effectively completing the separation and folding process of the sling in the overall structure. In order to enhance the ability of the lifting device to bear steel bars and reduce the burden of the lifting device's excessive deadweight on the lifting process, the first upper frame 1-1, the second upper frame 1-2 and the lower frame 2 adopt a closed rectangular frame structure. The first upper frame 1-1, the second upper frame 1-2 and the lower frame 2 are provided with a number of transverse support beams 4 for enhancing the frame's bearing capacity and longitudinal reinforcement ribs 5 for improving the rigidity of the overall frame structure. Six transverse support beams 4 are evenly arranged in the width direction of the frame, and four longitudinal reinforcement ribs 5 are arranged along the length direction of the frame. Push-pull components 6 are provided in the longitudinal reinforcement ribs 5 of the first upper frame 1-1 and the second upper frame 1-2.
