At the same time, the size of the scaffolding is often large, and a separate ladder is often required when installing the top frame, and the assembly process is not convenient and fast enough. Secondly, the scaffoldings that are spliced ​​together are all manually assembled. If the connectors on the scaffolding are not installed, the stability of the scaffolding will be poor, which poses certain safety hazards. Therefore, it is necessary to design a foldable scaffolding to overcome the above difficulties. Summary of the invention
