7. The pull-out, sliding, folding table according to claim 5, characterized in that: The front sliding pin is also provided with a pulley for fitting with the wall of the sliding groove.

8. The pull-out, sliding, folding table according to claim 1, characterized in that: The supporting frame (1) is a rectangular frame.

9. The pull-out, sliding, folding table according to claim 8, characterized in that: The support frame (1) comprises a front crossbeam (11), a rear crossbeam (12) and two side bars (13), and is enclosed by the front crossbeam (11), the rear crossbeam (12) and the two side bars (13), and the upper slide groove (131) and the lower slide groove (132) are arranged on the side bars (13).

10. The pull-out, sliding, folding table according to claim 1, characterized in that: The pull-out, translational, folding table further comprises supporting legs (3).

11. The pull-out, sliding, folding table according to claim 1, characterized in that: The support frame (1) also includes a locking structure, which locks the flip table board (2) when the pull-out translational folding table is switched to an unfolded state or a stowed state, thereby preventing the lower flip table board (2) from sliding.
