Further, the elastic sheet is of a U-shaped structure, and the positioning pin is fixed on one side wall of the elastic sheet and extends outwards; the elastic sheet is extruded in the connecting pipe after being arranged in the connecting pipe.
Further, the inner diameter of the support pipe is larger than the outer diameter of the connecting pipe, so that the connecting pipe can be inserted into the support pipe together with the elastic sheet.
Further, the fixing hole and the positioning hole are positioned on the same side, and the connecting pipe penetrates into the positioning hole and the fixing hole from the same side after rotating until the positioning pin aligns with the fixing hole.
Further, the two ends of the connecting pipe and the supporting pipes on the left side and the right side adopt symmetrical mounting structures.
Preferably, the support tube, the connecting tube and the elastic sheet are all made of metal materials, such as steel.
According to the utility model, the connecting pipe and the supporting pipe are made into separate structures, the connecting pipe and the supporting pipe are connected by adopting the elastic piece matched with the positioning pin, and the connecting pipe and the supporting pipe can be detached by pressing the positioning pin, so that the backrest plate can be rotated to meet the requirement of human comfort, and the backrest plate can be conveniently detached, so that the chair is more convenient to package, store and transport and lower in cost.
