[0002] Dining table refers to a table used for eating. It can be divided into bamboo and wood dining tables, marble dining tables, etc. according to the material. Bamboo and wood dining tables, as the name suggests, are dining tables made of bamboo and wood. In order to improve the adaptability of bamboo and wood dining tables, many manufacturers have begun to devote themselves to the research and design of bamboo and wood dining tables with adjustable tabletop area.

[0003] At present, there are many types of adjustable bamboo and wooden dining tables commonly seen on the market, among which the simplest structure is to directly set up a group of movable tabletop panels on the basis of the supporting mechanism, and then detachably install an adjustable tabletop panel between the group of movable tabletop panels. When it is necessary to expand the use area of ​​the dining table, a group of movable tabletop panels can be moved outwards respectively, and then the adjustable tabletop panel can be fixedly embedded between the group of movable tabletop panels. In order to ensure the splicing stability between the movable tabletop panels, or the splicing stability after adding an adjustable tabletop panel, the existing group of movable tabletop panels and the bottom side of the adjustable tabletop panels need to be fixedly installed with corresponding locking mechanisms, which not only has a relatively complex structure, but also requires personnel to lie on the bottom side of the tabletop to operate during operation, which is very troublesome and does not meet the needs of modern furniture use.

[0004] Therefore, the research purpose of the present invention is to design an adjustable bamboo and wooden dining table with a simple structure and which can significantly improve the convenience of the desktop adjustment operation. Summary of the invention
