[0031] To fold and unfold, the folding table leg is tilted outward, and the pivot support rod slides outward within the support rod slideway. When it slides to the bottom, it contacts the fold button. The folding table leg continues to tilt outward, and the fold button is forced upward. The torsion spring is compressed and deformed. When the pivot support rod slides past the end of the fold button, the torsion spring rebounds, pressing the fold button down against the pivot support rod, thereby securing the folding table leg. The folding table assembly is now fully unfolded, and the tension of the fold button against the pivot support rod can be adjusted by adjusting the height of the set screw on the folding connector. Specifically, when the set screw is lowered, the top of the folding table leg's leg cross tube contacts the set screw, reducing the extent of the folding table leg's opening. The end of the pivot support rod that passes through the support rod slideway of the folding main beam is closer to the inner side of the table top, resulting in a tighter tension when the fold button is pressed against the pivot support rod. Conversely, when the set screw is raised, the tension when the fold button is pressed against the pivot support rod is loosened.

[0032] To fold and close, press the end of the folding button to release the bottom from the pivot support rod, flip the folding table legs inward, and the pivot support rods slide inward within the support rod slides. Press and release the folding button, and the torsion spring will rebound and return to its original position. Continue to flip the folding table legs until they are flush with the table top. At the same time, the pivot support rods slide to the end of the support rod slides, passing through the raised points of the slides to limit and fix the pivot support rods, preventing the risk of the table legs falling. At this point, the folding table set is closed and folded.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1) The folding table structure provided by this technical solution has a stable structure, an improved folding mechanism, and cleverly utilizes the positional relationship between the table legs and the crossbeam, supplemented by support rods for fixation, to achieve a foldable usage scenario, thereby improving its practicality and convenience while ensuring stability and durability.
