At this time, the two hand-operated turntables 143 are rotated to drive the two first threaded rods 142 to rotate, so as to drive the two fixed blocks 12 to move to the right, so that the two fixed blocks 12 are moved out of the two fixed holes 10 respectively, thereby releasing the fixation between the two connecting blocks 8 and the two mounting seats 5. At this time, the two connecting blocks 8 can be pulled out of the two connecting grooves 7 respectively, so as to disassemble the steel wire rope body 2, thereby achieving the purpose of easy disassembly, and facilitating the replacement work of the sling steel wire rope. In the prior art, the two ends of the sling are usually fixedly connected with the main cable and the stiffening bar, which makes the replacement of the sling very inconvenient.
