The synchronous draw table of claim 3, wherein: Two ends of the lifting support (6) are respectively provided with lifting grooves (61), the lifting grooves (61) comprise upper grooves (611), lower grooves (612) and inclined grooves (613) connecting the upper grooves (611) and the lower grooves (612), the sliding rods (32) are fixed on the sliding blocks (3), one end of the sliding rods (32) is fixed with the sliding blocks (3), and the other end is slidably arranged in the lifting grooves (61); when the two side table plates (51) are synchronously opened, the corresponding sliding blocks (3) move on the sliding rails (2), simultaneously driving the sliding rods (32) to move from the upper grooves (611) to the lower grooves (612) through the inclined grooves (613), and the lifting support (6) synchronously drives the middle table plate (52) to be lifted to be flush with the side table plates (51); when the two side table plates (51) are synchronously closed, the corresponding sliding blocks (3) move on the sliding rails (2), simultaneously driving the sliding rods (32) to move from the lower grooves (612) to the upper grooves (611) through the inclined grooves (613), and the lifting support (6) synchronously drives the middle table plate (52) to fall back and be accommodated under the side table plates (51).

5. The synchronous draw table of claim 4, wherein: The inclined grooves (613) are connected to the middle parts of the lower grooves (612), when the two side table plates (51) are synchronously opened, the sliding rods (32) move along the inclined grooves (613) to the lower grooves (612) and first move in the direction of the outer side in the lower grooves (612), so that the side table plates (51) continue to move to the two sides, and interference between the middle table plate (52) and the side table plates (51) in the lifting process is avoided, after the middle table plate (52) is lifted, the side table plates (51) are reversely pushed to make the sliding rods (32) of the sliding blocks (3) move in the direction of the inner side in the lower grooves (612), and then the side table plates (51) are spliced with the middle table plate (52).

6. The synchronized draw table of claim 2, wherein: The middle table plate (52) is hinged to the support frame (1), when the two side table plates (51) are synchronously closed, the middle table plate (52) is rotated and accommodated at the bottom of the side table plates (51); when the two side table plates (51) are synchronously opened, the middle table plate (52) is rotated and flush with the side table plates (51).

7. The synchronized draw table of claim 1, wherein: The synchronous wheel (41) and the synchronous belt (42) are respectively provided with gear structures (411) and rack structures (421) capable of being meshed with each other.

8. The synchronized draw table of claim 1, wherein: The support frame (1) is provided with two parallel sliding rails (2), and the two sides of the side table plates (51) are respectively fixed with two sliding blocks (3) oppositely arranged on the two sliding rails (2).

9. The synchronized draw table of claim 1, wherein: The two sliding blocks (3) are symmetric about the center of the sliding rail (2).

10. The synchronized draw table of claim 1, wherein: A supporting leg assembly is arranged at the bottom of the support frame (1).
