The size of the third hinge hole 631 is larger than the size of the first hinge hole 611 and the size of the second hinge hole 621.

(12) Referring to FIGS. 1 and 4, the elastic button piece 42 is arranged in the opening slot 41. The V-shaped elastic piece 9 is arranged in each of the adjacent two support rods 1 in the other group. The V-shaped elastic piece 9 is provided with the elastic column 7, and the elastic column 7 abuts the button piece 42. The limiting member 10 is fixedly arranged on each of the four support rods 1. The limiting member 10 is located above the slide base 4, and the limiting member 10 is configured to limit the upward sliding position of the slide base 4.

(13) Referring to FIGS. 1, 2, 3, 4, and 9, when the highchair needs to be folded, the feeding tray 8 is first removed, and then the third locking piece 63 is moved outward to separate the hook portion 65 from the second locking piece 62. At this time, the two folding rods 5 are in a to-be-folded state. Subsequently, the button piece 42 is pressed to separate the elastic column 7 from the opening slot 41. Finally, the slide base 4 is grasped to slide down to fold the four support rods 1 and the four groups of folding rods 5. As the four support rods 1 are folded, the cloth seat 2 is folded.
