[0002] Tables and chairs are one of the commonly used furniture in people's life and study. Most of the existing tables and chairs adopt a split structure design, that is, the table is a table, and the chair is a chair. In some specific occasions, such as education and training, due to the small room, in order to place more tables and chairs, integrated tables and chairs are designed. That is, the table and chairs are integrated together. This type of structure generally extends in front of the seat with a vertical pole, and the top of the vertical pole is set on the table top. This integrated combination method is used to achieve the purpose of reducing the floor space.
