The table supports 2 are rotatably connected to the table plate 1, so that the table supports 2 can be turned over to the back of the table plate 1. The bench supports 4 are rotatably connected to the bench bodies 3, so that the bench supports 4 can be turned over to the back of the bench bodies 3. The specific folding structure and folding principle of the table supports 2 and the bench supports 4 are of conventional designs and will not be described here.

In this embodiment, each table support 2 has an upper support 21 and a lower support 22 capable of extending out of or retracting into the upper support 21. The table plate 1 is capable of being lowered to the same height as the bench bodies 3 when the upper supports 21 and the lower supports 22 are retracted relative to each other. Each upper support 21 comprises a upper vertical tube 211, each lower support 22 comprises a lower vertical tube 221 and a lower transverse tube 222 connected to the bottom of the lower vertical tube 221; the upper vertical tubes 211 and the lower vertical tubes 221 are telescopic with each other and is capable of moving up and down relative to each other. A locking mechanism 6 is disposed between one upper vertical tube 211 and the corresponding lower vertical tube 221. When the table plate 1 is lifted up, that is, when the upper vertical tubes 211 are lifted up relative to the lower vertical tubes 221, the positions of the upper vertical tubes 211 can be locked by the locking mechanism 6, so that the upper vertical tubes 211 are kept in the lifted-up state. The locking mechanism 6 may adopt the locking mechanism on the existing extension tubes, and the specific structure will not be described here.

In this embodiment, each bench support 4 has L-shape and has an upper rod 41 and a horizontal rod 42. In this embodiment, the horizontal rods 42 are also of a tubular structure. Each lower transverse tube 222 is rotatably connected to the corresponding horizontal rod 42 through the connecting pieces 5.

When the picnic table needs to be folded, the locking mechanism 6 is released first, so that the upper vertical tubes 211 move down relative to the lower vertical tubes 221, that is, the upper supports 21 and the lower supports 22 of the table supports 2 are retracted relative to each other. At this time, the table plate 1 is lowered to the same height as the bench bodies 3. Then, the table supports 2 are turned over to the back of the table plate 1, and the bench supports 4 are turned over to the back of the bench bodies 3.
