[0002] Furniture refers to a broad category of equipment and facilities essential for people to maintain normal life, engage in production practices, and carry out social activities. Furniture comes in many varieties, including large items like wardrobes, tables, beds, and sofas, as well as household appliances like cooking utensils. These items are used in daily life and social activities for sitting, lying down, leaning on, storing things, and providing space. To reduce space usage, many homes often include folding tables.

[0003] At present, most folding table furniture products in the furniture market use flatbed carts during the transportation process. When transporting folding tables in batches, these flatbed carts are generally stacked. As a result, the folding table brackets stacked at the bottom will often leave marks on the table top, affecting product quality. Adding protective pads between products to avoid this problem is also rather troublesome. Even with protective pads, the folding brackets are easily deformed under pressure. In addition, through investigation, it was learned that if the folding table is placed vertically on a flatbed cart for transportation, although the problem of squeezing can be avoided to a certain extent, the stability is very poor and requires additional fixation, which is also very inconvenient.
