6. The dovetail joint structure for the solid wood furniture according to claim 1, wherein the connecting splint (6) is fixed with the dovetail body (3) by gluing, and the first fixing ring (605) and the second fixing ring (606) are symmetrically arranged on the dovetail body (3).
7. A connecting method of a dovetail joint connecting structure for solid wood furniture is characterized by comprising the following working steps:
the method comprises the following steps: connecting one side of a first connecting plate (1) with one side of a second connecting plate (2) to form a plurality of tenon grooves between the first connecting plate (1) and the second connecting plate (2), placing a plurality of dovetail bodies (3) on the tenon grooves and vertically extruding from top to bottom at the same time to enable the dovetail bodies (3) to move downwards between the first connecting plate (1) and the second connecting plate (2) until the dovetail bodies (3) are flush with the highest positions of the first connecting plate (1) and the second connecting plate (2), and enabling the first connecting plate (1) and the second connecting plate (2) to be connected through the dovetail bodies (3);
step two: when the first connecting plate (1) and the second connecting plate (2) need to be separated, the first fixing cap (7) and the second fixing cap (8) are respectively rotated anticlockwise in the same direction at the lower end of the dovetail body (3), so that the connecting column (9) rotates in the first sleeve column (601) and moves downwards, the limiting ring (10) rotates in the first limiting column (603) and moves downwards until the limiting ring (10) moves downwards to the upper end of the baffle (607), and the first fixing cap (7), the second fixing cap (8) and the connecting column (9) are separated from the first fixing ring (605) and the second fixing ring (606) and extend downwards;
step three: through upwards extruding first locking cap (7) and second locking cap (8), the thrust of production passes through spliced pole (9) and spacing ring (10) and transmits to splice plate (6), transmits thrust to forked tail body (3) through splice plate (6), makes forked tail body (3) rebound under thrust, until forked tail body (3) and first connecting plate (1) and second connecting plate (2) separation, carries out the split with first connecting plate (1) and second connecting plate (2).
