By connecting the panels to the table and chair frames, the basic function of the table and chairs can be achieved. However, since the table and chair panels need to be clamped and fixed to the frames and connectors during the table and chair assembly process, the existing table and chair assembly process is inconvenient for fixing the panels and frames, resulting in inconvenient installation and affecting installation efficiency.

Two sliding grooves are formed through the workbench, and two sliders are slidably arranged within each groove. Two clamping strips are symmetrically arranged on the four sliders, and two sliding rods are symmetrically installed below the four sliders. Two fixing plates are symmetrically installed below the workbench, and a bidirectional screw is rotatably installed between the two fixing plates. The two ends of the bidirectional screw are respectively inserted into threaded holes in the two sliding rods. This device can fix the components together, thereby improving the installation efficiency of tables and chairs. However, its drawback is that the position of each component cannot be adjusted after the tabletop is fixed. Adjusting the position of the fixing frame only through sleeves cannot meet different installation needs, and it is inconvenient to handle the installation of tabletop corners and connecting structures. It is not flexible enough in use. Therefore, a stable connection structure assembly device for school desks and chairs is needed. Utility Model Content
