[0002] With the development of construction equipment, the research and application of scaffolding has made rapid progress, and various scaffolding erection forms have emerged in large numbers. The scaffolding is formed by connecting a number of steel pipes. The existing scaffolding is generally connected by bolts and buckles. Therefore, it takes a lot of time to tighten and remove the bolts when building or dismantling the scaffolding, which makes the efficiency of scaffolding construction low, and the scaffolding bolts and buckles that have been used for a long time will slip, affecting the safety of use. The scaffolding currently used is not only complex in structure and cumbersome to install, but also wastes materials, causes serious loss, and requires a lot of labor and workload. The invention patent with application number CN201410601071.7 discloses a scaffolding, including columns, long transverse tubes, first connecting fasteners, second connecting fasteners and bearing plates. The columns and long transverse tubes are seamless square tubes, and through holes are provided at both ends of the long transverse tubes. The first connecting fastener is a coaxial double hinge structure, and the second connecting fastener is a hinge structure with double bolts. A base is fixed on the side of the hinge structure, and a protrusion extends axially from the base along the hinge structure, and the protrusion matches the size of the through hole. The bearing plate is a flat plate structure, and the upper part of both sides of the plate extends downward to form a hook. The above patent uses the first connecting fastener to connect the two columns, and then uses the second connecting fastener to fix the long transverse tube on the column, and then uses the bearing plate to hang on the long transverse tube. Although this scaffolding connects the columns and the transverse tubes through the connecting fasteners, although the traditional connecting parts have been improved, there are still installation problems, low construction efficiency, and affect the construction progress.
