[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The assembly method is to weld connectors on the steel columns, then connect the steel beams through connecting plates, and reinforce the connections of the connecting plates by welding.

[0003] A patent document with Chinese patent number CN218715402U discloses a steel structure reinforcement device, which proposes the problem that "after the two cross beams of some current steel structures are fixed, reinforcement rods need to be installed on the two cross beams to reinforce the two cross beams. The stability of the steel structure cross beams can be improved under the action of the reinforcement rods. However, some current reinforcement rods have some problems when used. The length of each reinforcement rod is fixed during the production process, and the length of the reinforcement rod cannot be adjusted during use, resulting in each reinforcement rod being only applicable to steel structure cross beams of fixed length, reducing the scope of use of the reinforcement rod" and solves the problem.

[0004] However, the above-mentioned prior art cannot be quickly adjusted over a large range when in use. If the length difference is large during use, it takes a long time to twist the adjustment component, which is time-consuming and labor-intensive and very inconvenient. Summary of the invention
