Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a type of folding table that can be unfolded and put into a use state, or can be folded with a simple operation into a storage state of small volumes.

[0002]

[Prior art]

 Traditional tables have the basic structure of supporting the top plate with mostly three or four feet, and while such tables are extremely convenient in manufacture and use, they also have many drawbacks. Was. In other words, because the feet are fixed to the top plate and cannot be folded, it is inconvenient to take up space and carry it when going out.

[0003] At present, there are already several tables that can be changed in shape. For example, a foldable extension board is added to four sides of a square top plate, and a circular table is formed by expanding the four extension plates. Some are designed to make up a table, while others are able to fold a foot or top plate. However, such known folding tables mostly fold the top plate locally or fold between the top plate and the feet, and the volume after folding is considerably large, taking up space for storage. It was inconvenient to carry it outdoors.
