The upper end of the connecting frame 701 is symmetrically fixedly connected to two fixed blocks 705, and the two fixed blocks 705 are connected to the connecting block 707 through a connecting rope 706. The lifting assembly 7 is fixedly connected to the wire rope 6 through the connecting block 707.

[0028] By means of the connection structure between the lifting mechanism 704 and the sliding rod 702 and the forward and reverse screw rods 703, by turning the adjusting hand wheel 7031 to rotate the forward and reverse screw rods 703, the two lifting mechanisms 704 can be moved towards or in opposite directions in the connecting frame 701, so that the lifting diameter can be adjusted accordingly according to the diameter of the steel cage, so as to be suitable for the lifting and placing of steel cages with different diameters.

[0029] Please refer to Figure 2 , Figure 3 and Figure 5 The lifting mechanism 704 includes a sliding block 7041, a sliding groove 7042, a spiral hole 7043, a mounting plate 7044, a bolt 7045, a lifting ring 7046, a lifting rope 7047 and a hook 7048.
