The connection seat 3 is inserted into the connection groove 14, and there is friction between the peripheral side wall of the connection seat 3 and the peripheral side groove wall of the connection groove 14. The peripheral side wall of the connection seat 3 is fixedly connected with a limit ring 34, which is an annular structure. The vertical cross-section of the limit ring 34 is an arc surface structure, and the arc surface convex side of the limit ring 34 faces away from the connection seat 3. The limit ring 34 is made of a material with a certain elasticity, such as plastic, wood, etc. The peripheral groove wall of the connection groove 14 is formed with a limit groove 141 adapted to the limit ring 34. When the connection seat 3 is inserted into the connection groove 14, the limit ring 34 is stuck in the limit groove 141, so that the connection seat 3 is initially fixed.

[0043] A plug-in slot 31 is formed on the top of the connection seat 3. The plug-in slot 31 is adapted to the connection column 23. The connection column 23 is inserted into the plug-in slot 31, and the side wall of the connection column 23 is in sliding contact with the side wall of the plug-in slot 31. When the connection seat 3 abuts against the slot wall of the connection slot 14 away from the slot opening and the connection column 23 abuts against the slot wall of the plug-in slot 31 away from the slot opening, the bottom of the seat plate 2 corresponding to the chair frame 11 abuts against the chair frame 11, and the seat plate 2 corresponding to the back column 13 abuts against the back column 13.

[0044] The side walls of the connection seat 3 are respectively formed with slide grooves connected to the plug-in slot 31, and the extension direction of the slide groove is perpendicular to the extension direction of the plug-in slot 31. The connection seat 3 is provided with a fixed column 32, and the fixed column 32 corresponds to the slide groove one by one. The fixed column 32 slides in the slide groove, and the length of the fixed column 32 is greater than the sum of the depth of the card slot 15 and the thickness of the slot wall of the plug-in slot 31.

[0045] The side walls of the connecting groove 14 are respectively formed with slots 15, and the slots 15 correspond to the fixed posts 32 one by one. The bottom of the connecting post 23 is inclined to form a sliding surface 232, and the sliding surface 232 corresponds to the fixed post 32 one by one. When the connecting post 23 is inserted into the slot 15, the fixed post 32 slides on the sliding surface 232, and the connecting post 23 pushes the fixed post 32 to be inserted into the slot 15.

[0046] A fixing groove 231 is formed on the outer peripheral side of the fixing column 32, and the fixing groove 231 corresponds to the fixing column 32 one by one, and when the connecting column 23 abuts against the groove wall on the side away from the groove opening of the plug-in groove 31, the fixing groove 231 is aligned with the fixing column 32. The connection structure of the lacquer chair also includes a driving component 4, and when the fixing groove 231 is aligned with the fixing column 32, the driving component 4 drives the fixing column 32 to be inserted into the fixing groove 231, and at the same time, the part of the fixing column 32 away from the fixing groove 231 is simultaneously in the card slot 15.

[0047] The driving assembly 4 includes a driving block 41 and a driving spring 42. The driving block 41 is fixed on the side wall of the fixed column 32.
