[0052] The top support vertical plates 402 are a plurality of pieces, and the bottom of each top support vertical plate 402 is an inverted V-shaped groove, which matches the inverted V-shaped inclined surface at the top of the sheet plate 401. A plurality of top support vertical plates 402 are installed at intervals from left to right on the top of each sheet plate 401 by welding, and are fixedly installed below the lifting tool body 300 by bolts through the first corner plates 403 at both ends of their tops.

[0053] In some of the embodiments, such as Figure 9 and Figure 10 shown, the suspension sling 500 mainly consists of a plurality of groups of sling ropes 501 and hooks 502. The hook 502 adopts a conventional hook structure, and the sling rope 501 can adopt a cable chain, a sling belt or a lifting rope. And for the convenience of quickly disassembling the sling rope 501 and the hook 501, sling rings that are snap-connected to the hook 502 are respectively provided at both ends of the sling rope 501.

[0054] Specifically, a plurality of sling ropes 501 are sleeved at intervals from left to right on the bottom of the workpiece 700, and their two ends are detachably connected upward to the corresponding hooks 502. A plurality of hooks 502 are respectively located in the suspension holes 404 on the umbrella 400, their upper ends are connected to the corresponding lower reinforcing plate 302, and their lower ends are detachably connected to the sling rings at the ends of the corresponding sling ropes 501.

[0055] A pair of hooks 502 arranged front and back at the bottoms of the front and back frames of the spreader body 300 are correspondingly connected to a sling 501, and this pair of hooks 502 and the corresponding sling form a lifting point. According to the bottom of the spreader body 300, n groups of lifting points are provided, and the positions and spacings of each lifting point can be flexibly set as required, and steel pipes and bars of different lengths and different specifications can be suspended.

[0056] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10 shown, in order to improve the stability of the workpiece 700 during the up and down lifting in the Z-axis direction and the front and back movement in the Y-axis direction, a limit baffle 600 is further installed at the bottom of one end of the spreader body 300.

[0057] Specifically, the limit baffle 600 is an inverted vertical triangular frame structure, and the end face opposite to the end of the workpiece 700 on its inner side is a vertical plane, and this vertical plane is provided with a mesh structure, which can be in abutting connection with the end face of the workpiece 700 and can play a certain limiting role on the workpiece 700.

[0058] In addition, the top end of the limit baffle 600 is correspondingly connected to a plurality of first mounting plates 307 at the end of the spreader body 300 through a plurality of second gussets 601.
