[0026] By adopting the above technical solution, the staff can adjust the height of the mounting block assembly 1 to a certain extent through the cooperation of structures such as the rotating plate 661 and the second screw rod 662 when needed, so as to better meet the working requirements in different situations.

[0027] Specifically, the lifting assembly 66 further includes a guide rod 663. The guide rod 663 is installed above the support plate 5 and on one side of the second screw rod 662.

[0028] By adopting the above technical solution, the structure can perform a certain limit guiding work on the movement of the support plate 5 through the guide rod 663, thereby reducing the possibility of the support plate 5 and the structures thereon rotating and deviating during the movement process.

[0029] When this embodiment is in use, when the staff needs to use the structure to strengthen the work at the steel structure connection, the staff respectively insert the two insertion blocks 3 into the two connection blocks 7 and fix them through the two fixing mechanisms 2.

[0037] The working principle and use process of the utility model are as follows: when the staff needs to use the structure to strengthen the joint of the steel structure, the staff will insert the two plug blocks 3 into the two connecting blocks 7 respectively, and fix them through the two fixing mechanisms 2, and then respectively rotate the two knobs 62 in the distance adjustment lifting device 6, thereby driving the two first screw rods 63 to rotate, the first screw rod 63 is threadedly connected to the vertical plate 64, the first screw rod 63 is bearing-connected to the connecting plate 65, and the movable plate 67 under the connecting plate 65 is tightly attached to the outer casing 61, so the two first screw rods 63 drive the two movable plates 67 and the two fixed block assemblies 4 and other structures to move, thereby adjusting the distance between the two mounting block assemblies 1, and then respectively rotate the two rotating plates 661 in the two lifting assemblies 66 as needed, thereby respectively driving the two second screw rods 662 to rotate, and the second screw rod 662 and the movable plate 67 are screwed together. The second screw rod 662 is connected with the support plate 5 by a bearing connection, and the guide rod 663 is connected with the movable plate 67 by a sliding connection, so the two second screw rods 662 respectively drive the two support plates 5 and other structures to move, thereby adjusting the heights of the two mounting block assemblies 1 respectively, and then the two mounting block assemblies 1 are installed and fixed in the working position, and the work is completed; when it is necessary to adjust the angle of a certain mounting block assembly 1, the screw 83 in the rotating adjustment device 8 is rotated to disengage it from the threaded hole 82 on the rotating plate 81, and then the mounting block assembly 1 is pulled to rotate it and the rotating plate 81 around the connecting shaft 84 to the required angle, and the screw 83 is rotated in the opposite direction to connect it with the corresponding threaded hole 82, thereby fixing the relative position between the rotating plate 81 and the fixed cylinder 85 to prevent the rotating plate 81 and the mounting block assembly 1 thereon from accidentally rotating, and the adjustment is completed, which better meets the work needs in different situations.
