One end of the linkage rod 8 is connected to the connecting shaft, and the other end is connected to the sliding block II 92 provided in the chute 10 on the adjacent connecting rod I7. the

According to actual needs, the desktop of the combination table is hexagonal or octagonal, and then the desktops of each small table are set as equally divided triangular structures. In this embodiment, the hexagon is taken as an example, and each small table is divided into an isosceles triangular table top. The triangular desktop of the small table is divided into the main desktop 2 and the auxiliary desktop 3 separated by the top corner. The main desktop 2 is trapezoidal, and the auxiliary desktop is triangular. The bottom of the main desktop 2 is provided with a push mechanism that controls the support of the auxiliary desktop 3 and hangs down. This design can ensure that when it is in the combined state, the auxiliary desktop 3 is supported and spliced together with the main desktop 2 to form a complete polygonal desktop; when unfolded, the auxiliary desktop 3 hangs down freely, and the sharp corners are retracted, which does not affect the use as a separate small table. Safe and convenient. The push mechanism includes a slide rail 12, a connecting rod II9 and a slider I91 placed in the slide rail 12. A push rod 11 is arranged in front of the slider I91. One end of the connecting rod II9 is connected to the slider II92, and the other end is connected to the slider I91. The two sliders II92 on the same connecting rod I7 are connected with the connecting rod II9, and the other ends of the two connecting rods II9 are all connected with the slider I91 located under the same main table top 2 . The push mechanism supporting the auxiliary desktop 3 is a double slider mechanism in which two ends of the connecting rod II9 are connected with two sliders. the
