However, only the chair back and the chair seat are folded into a flat shape, the space occupation is still larger, and the daily storage and the logistics transportation are not facilitated. Therefore, a Kemeter folding chair with a detachable cross rod also appears on the market, and the cross rod can be detached, so that the brackets on the left side and the right side can be further folded towards the middle, the occupied space after folding and storage is smaller, and the folding and storage is convenient for logistics transportation and daily storage. However, when the folding chair is stored, part of the parts (such as a cross rod and the like) are separated from the main body part of the chair, so that the disassembly and the assembly operations are complicated, and the separated parts are easy to lose, so that the folding chair cannot be assembled again for use.

In order to solve the problems, some folding chairs have a cross bar designed into a folding structure or a semi-detachable structure, and the folding chair does not have redundant separated parts after being folded and stored, so that the operation convenience is improved. For folding of the cross rod, a rod folding hinge does not exist at present, but a conventional hinge structure is thin, the structural strength is poor, and the limit stability after unfolding is also poor. For this reason, it is necessary to design a hinge for a tube having an unfolding limit function to meet the rail folding needs of the outdoor folding chair.
