Jointed tables and chairs are mainly formed by supporting columns (15), a supporting column (2), a base (1), upper plates (12), lower plates (10) and the like, and are characterized in that the upper plates (12) are connected with the supporting columns (15) through rotating shafts (13), limiting baffles (14) are connected with the supporting columns (15), when the upper plates (12) are turned over upwards to abut against the limiting baffles (14), the uppermost ends of the upper plates (12) cannot exceed a center line, and sliding blocks (5) are in clearance fit with the supporting columns (15) and can easily slide. When the lower plates (10) rotate around rotating shafts (9), limiting bosses (8) can move in limiting grooves (7). A spring (3) is sleeved between the supporting column (2) and a spring matched boss (4). A table and chair combination meeting different teaching requirements is provided, teachers and students can sit face to face, and learning exchanging is facilitated. Meanwhile, when the upper plates and the lower plates are turned over upwards, large space can be emptied, people can take seats and leave the seats conveniently, and trash cleaning is conveniently achieved.
