During the folding process, the left inclined support rod is folded by the U-shaped connecting piece moving closer to the left inner tube.

[0012] A U-shaped connecting piece is fixedly sleeved on the right diagonal support rod. The other end of the U-shaped connecting piece is hinged to a right horizontal support rod, and the other end of the right horizontal support rod is hinged to the lower right connecting sleeve. During the folding process, the right diagonal support rod is folded by the U-shaped connecting piece moving closer to the right inner tube.

[0013] The left and right diagonal support rods serve to connect the inner tube and the diagonal support rods, providing support.

[0014] The folding operation of this utility model requires no tools and can be completed by one person within 30 seconds. The specific steps are as follows: Unlock the pin: Pull out the pin that connects the curved connecting piece to the chair frame to release the locking state of the chair frame; Internal pressure chair tube: The left chair tube assembly and the right chair tube assembly are brought together inward. At this time, the scissor-type inclined support tube assembly retracts inward simultaneously. The left outer tube moves upward relative to the left inner tube, and the right outer tube moves upward relative to the right inner tube. Folding up the support rods: As the chair tube assembly closes, the left diagonal support rod moves towards the left inner tube under the guidance of the U-shaped connecting piece, and the right diagonal support rod moves towards the right inner tube. The left and right horizontal support rods fold simultaneously. Folding chair frame: Fold the left and right chair frames towards the chair tube until they are parallel to the chair tube to complete the overall folding. When folded, the product volume is only 1 / 4 of its unfolded state, which can be easily put into a backpack or car storage compartment, greatly improving portability.
