[0026] Embodiment 1: Please refer to Figures 1 - 6 , a Wensi chair, including a chair seat board 1. A first connecting block 2 and a second connecting block 3 are arranged below the chair seat board 1. A first convex block 201 is arranged at the upper end of the first connecting block 2, and a first groove 202 is arranged on the side of the first connecting block 2. A second convex block 301 is arranged at the upper end of the second connecting block 3, and a second groove 302 is arranged on the inner side of the second connecting block 3. The first groove 202 and the second groove 302 are locked by a double V-shaped locking fastener 4. A first chair leg 5 is arranged at the lower end of the first connecting block 2, and a second chair leg 6 is arranged at the lower end of the second connecting block 3.

[0027] The bottoms of the first chair leg 5 and the second chair leg 6 are mortise-and-tenon connected to an arc-shaped connecting piece 7.

Made of wood materials, it is both environmentally friendly and healthy, meeting the pursuit of modern people for a healthy life.

[0029] Specific process and working principle of the work:

[0030] When assembling the Wensi chair, first lock the first connecting block 2 and the second connecting block 3 together through the double V-shaped locking fastener 4 to form the basic frame of the chair. Then, connect the first chair leg 5 and the second chair leg 6 to the lower ends of the first connecting block 2 and the second connecting block 3 respectively. Next, perform mortise and tenon connections between the arc-shaped connecting piece 7 and the bottoms of the first chair leg 5 and the second chair leg 6 respectively to ensure the stability of the chair. Finally, insert the plug-in bottom plate 8 into the I-shaped block slot 901 of the I-shaped bottom plate connecting block 9 to complete the assembly of the entire chair. During use, the chair can adjust the angle between the plug-in bottom plate 8 and the first chair leg 5 and the second chair leg 6 to adapt to different usage requirements.

[0031] Steps of assembly:

[0032] Place the first connecting block 2 and the second connecting block 3 on a flat ground and ensure that their positions are aligned. Use the double V-shaped locking fastener 4 to lock the upper ends of the first connecting block 2 and the second connecting block 3 together to ensure a firm connection between them. Connect the first chair leg 5 and the second chair leg 6 to the lower ends of the first connecting block 2 and the second connecting block 3 respectively to ensure a tight and stable connection.

[0033] Perform mortise and tenon connections between the arc-shaped connecting piece 7 and the bottoms of the first chair leg 5 and the second chair leg 6 respectively to ensure the overall stability of the chair. Insert the plug-in bottom plate 8 into the I-shaped block slot 901 of the I-shaped bottom plate connecting block 9 to ensure that the angle between the plug-in bottom plate 8 and the first chair leg 5 and the second chair leg 6 meets the usage requirements. Check the assembly of the entire chair to ensure that all components are firmly connected and there is no shaking phenomenon.
