Limiting plate four 9 is fixed to the lower part of the side where the two sliding plates 3 are close to each other. The limiting plate four 9 is used to limit the sliding plates 3 after they are unfolded. After the corresponding limiting plate 8 is positioned, the sliding plate 3 and the extension plate 4 can slide out from the bottom of the tabletop 1, preventing the extension plate 4 from extending excessively from the bottom of the tabletop 1 and causing instability. After the sliding plates 3 on both sides of the bottom of the tabletop 1 extend along the guide groove 101, the hinge plate 5 is used to flip and support the extension plate 4 from the corresponding sliding plate 3 and make it flush with the tabletop 1. Finally, the sliding plates 3 push back the two supported extension plates 4, so that the extension plate 4 and the tabletop 1 are spliced together, thereby achieving the effect of conveniently expanding the dining table; it also includes a limiting plate 2 7, so... The second limiting plate 7 is fixed to one end of each other on the inner wall of the two sliding plates 3. The sliding plates 3 are used to limit the upward flipping and supporting extension plate 4, so that the top surface of the extension plate 4 can be flush with the top surface of the table board 1 after it is vertically supported on the sliding plates 3. The height of the first limiting plate 6 is lower than the height of the second limiting plate 7. Both the first limiting plate 6 and the second limiting plate 7 are L-shaped plates.
