[0027] Specifically, the bottom of the mortise and tenon hole on the main part of solid wood furniture is designed with an expansion space, and a tapered groove is opened at the end of the double-headed tenon, and a tenon wedge 9 is embedded in the tapered groove. The top of the wedge end of the double-headed tenon is inserted directly to the bottom of the mortise and tenon hole 12, and then pressure is applied to the other top of the double-headed tenon. The tenon wedge 9 is squeezed into the tenon groove 61, and the outer edge of the tenon groove 61 expands outward under the action of the tenon wedge 9 to occupy the designed space at the bottom of the mortise and tenon hole, thereby achieving the purpose of integrated combination of structural components, wherein the double-headed tenon can be set as a double-headed cylindrical tenon 5 or a double-headed rectangular tenon 6, and the corresponding mortise and tenon hole shape corresponds to the shape setting of the double-headed tenon.

[0028] The table of this embodiment uses a single solid wood material as the main component. A mortise and tenon hole is drilled on a designated design surface. The hole diameter is set to half the board thickness and the hole depth is 1.5 times the hole diameter. The bottom of the mortise and tenon hole is enlarged with a petal-shaped curved chisel to form a horseshoe-shaped bottom. The horseshoe-shaped fan-shaped bottom diameter is 2 mm larger than the hole diameter, the horseshoe shape is 5 mm high, and the top diameter is the same as the circular hole. Alternatively, a rectangular hole can be designed. The hole width is half the board thickness and the hole depth is 1.5 times the hole width. The bottom of the rectangular hole is chiseled with a petal-shaped flat chisel to form a horseshoe-shaped bottom diameter along the wood grain. The horseshoe shape is 2 mm larger than the hole diameter, the horseshoe shape is 5 mm high, and the top edge is the same width as the rectangle. The expansion of the horseshoe-shaped hole wall provides space for the groove of the tenon outside the mortise groove. A single-headed cylindrical tenon, a double-headed cylindrical tenon or a double-headed rectangular tenon is assembled in each set mortise and tenon hole, and a tenon wedge is respectively inserted in the cylindrical tenon and / or rectangular tenon groove. The density of the tenon wedge material is the same as that of the main part of the chair. When making furniture of a certain material, the material density must be measured first, and then the length of the tenon wedge extending out of the tenon groove is calculated. During assembly, wax is applied to the conical surface of the tenon groove and the conical surface of the tenon wedge, and the small head of the tenon wedge is inserted into the tenon groove, and the conical surface of the tenon wedge is tangent to the conical surface of the tenon groove, so that the large head of the tenon wedge is exposed to form a tenon wedge assembly.
