[0046] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, each of the connecting plate assemblies 2 is further provided with two fixing plates 23, two connecting shafts 24 and at least two fasteners 25. The two fixing plates 23 are respectively disposed on the side away from the second connecting plate body 22 on the two first connecting plate bodies 21. The two connecting shafts 24 are laterally spaced on both sides of the mounting groove 211. Each connecting shaft 24 connects the two first connecting plate bodies 21, the second connecting plate body 22 and one of the fixing plates 23 away from the other connecting plate assembly 2. At least two fasteners 25 are laterally spaced, and the two ends of each fastener 25 are respectively connected to the two fixing plates 23. In this invention, two corresponding first connecting plates 21, a second connecting plate 22, and a fixing plate 23 are connected by the connecting shaft 24, and another fixing plate 23 is connected by the fastener 25. Each fixing plate 23 connected to the connecting shaft 24 in each connecting plate assembly 2 is provided with two connecting through holes 221, and each of the two fixing plates 23 in each connecting plate assembly 2 is provided with through holes corresponding to each fastener 25, ensuring the integrity of the connection structure and improving safety.

[0047] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 2As shown, each of the connecting shafts 24 is provided with a pin body 241 and a blocking member 242. One end of the pin body 241 is provided with a boss 2411. The pin body 241 passes through the two first connecting plates 21, the second connecting plate 22, and a fixing plate 23 away from the other connecting plate assembly 2.

Figure 3As shown, the mounting groove 211 is a vertically arranged elongated groove. The width of the elongated groove is not less than the diameter of the upper shaft 1 of the lifting point, so that the first connecting plate 21 can pass through the upper shaft 1 of the lifting point and can adapt to a certain angle of rotation to prevent structural deformation.

[0053] This utility model embodiment also provides a lifting system, including the aforementioned connection structure for hoisting. The connection structure includes an upper lifting shaft 1, two connecting plate assemblies 2, and a lower lifting shaft 3.
