[0020] As Figure 1 shown in the prior art, a large sun umbrella (tent) is of a foldable structure. When unfolded for use, the movable connecting piece 2 needs to be moved upward to the upper end to be locked in the umbrella stand 1 to form the unfolded use state. When folding, the connecting piece 2 is unlocked at the upper end of the umbrella stand 1, and then the sun umbrella body is folded. When folding, the connecting piece 2 moves downward to the lower end, and the sun umbrella body forms a folding state. When the connecting piece 2 moves in the umbrella stand 1, contact and friction between the connecting piece 2 and the umbrella stand 1 are easy to scratch the paint coating on the outer surface of the umbrella stand 1, causing scratches. Especially during the folding process, a large folding force needs to be manually applied to the overall structure to fold the overall structure. At this time, the connecting piece 2 and the umbrella stand 1 are more likely to produce scratches, and the scratches produced are more obvious, which has certain disadvantages. If the rigid contact and friction of the connecting piece 2 when moving in the umbrella stand 1 are reduced, the paint coating of the umbrella stand can be effectively prevented from being scratched during the movement of the connecting piece, which can improve the quality of the sun umbrella.
