[0084] Embodiment 6

[0085] As Figures 9-18 shown, the adjusting member 31 can move relative to the connecting member 32. When the adjusting member 31 moves relative to the connecting member 32, it can drive the first support member 1 and the second support member 2 to approach or separate. This design can be that the adjusting member 31 moves relative to the connecting member 32, or the connecting member 32 and the adjusting member 31 move relative to each other. In this way, the lengths of the first movable member 3 and the second movable member 4 can be synchronously increased or decreased, thereby adjusting the distance between the first support member 1 and the second support member 2 to achieve the adjustment of the spacing to adapt to different types of sofas.

[0086] Embodiment 7
