The lower component also includes a spring assembly 15, and the spring assembly 15 includes a first spring 151 and a second spring 152. The first spring 151 and the second spring 152 are cross-stacked and received in a divergent state in the lower receiving groove 81 of the lower component 8. The first spring 151 and the second spring 152 are cross-stacked and received in a divergent state in the lower receiving groove 81 of the lower component 8. The second elastic piece 152 is vertically crossed, and the first elastic piece 151 and the second elastic piece 152 both have a bending structure that bends downward toward the middle, bends slightly upward on both sides, and then bends downward at both ends. The support leg 17 is rotatably connected to the lower receiving groove 81 of the lower component 8 through the second rotating shaft 19. The first elastic piece 151 and the second elastic piece 152 bypass the second rotating shaft 19 and the ends are located on the inner wall of the support leg 17. Under the action of the first elastic piece and the second elastic piece, the support leg 17 is kept in an outward stretched state with the second rotating shaft as the rotating axis.

[0080] In this embodiment, a chair cloth is also included, and the chair cloth is detachably mounted on the end of the support arm 16 .

[0081] When using the folding chair of this embodiment 3, it can be rocked forward and backward, wherein Figure 18-19 The diagram shows the maximum forward swing position, at which point the second limiter limits the forward swing position of the rear swing element. Under the linkage between the upper assembly and the front swing element, the upper assembly cannot swing forward any further. Figure 20-21 The figure also shows the maximum position of the backward swing. At this time, the first limit portion limits the backward swing position of the front rocking element. Under the linkage of the upper component and the rear rocking element, the upper component can no longer swing backward.

[0082] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structural or process transformations made using the contents of the present invention specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of patent protection of the present invention.
