Referring to Fig. 1～4, the utility model comprises two side boards 3 that have table legs identical in structure, be provided with between two side boards 3 by the first desktop board 4, the second desktop board 5 and the 3rd desktop board 7. The first desktop board 4 is fixedly connected to the two side boards 3, and each side board 3 is provided with a horizontal chute 1 that enables the second and third desktop boards 5, 7 and the first desktop board 4 to be at the same height , and the second and third desktop boards 5 and 7 are embedded in the horizontal chute; each side board 3 is also provided with a vertical chute 8 that can move the third desktop board 7 up and down, and the vertical chute 8 is provided with a Support the boss of the second desktop board 5; one side of the second and third desktop boards 5 and 7 is actively connected together by the connecting rod structure 2, and the connecting rod structure 3 is made up of two connecting rods hinged together. The link structure 3 has a locking function; the other side of the second desktop 5 is close to the third desktop 7 , and the other side of the third desktop 7 is close to the first desktop 4 .

The two ends of the second desktop board 5 are provided with the first, second and third roller sets matched with the horizontal chute 1, and the first roller group is positioned at one side of the second desktop board 5, and the second roller group is positioned at the second desktop On the other side of the board 5, the first roller set is far away from the first desktop board 4; the third roller set is located between the first and second roller sets. Each side plate 3 is provided with the first arc chute 6 that makes the second desktop 5 rotate clockwise 90 °, the central angle of the first arc chute 6 is 90 °, the first arc chute 6 and The first roller group cooperates, and the radius of the first arc-shaped sliding groove 6 is smaller than the maximum distance that the third desktop board 7 can move downward. Each side plate 3 is also provided with a second arc-shaped chute 9 for the third roller group to pass through when the second desktop 5 rotates clockwise, the central angle of the second arc-shaped chute 9 is 90 °, and the second arc-shaped chute 9 The second arc chute 9 is concentrically arranged with the first arc chute 1 .

The utility model has the following three working states, which are specifically described as follows:

1. The first working state (large multi-purpose table such as a drawing table)

As shown in Figure 1, the first desktop board 4, the second desktop board 5 and the third desktop board 7 are embedded in the horizontal chute 1 to form a desktop, and the third desktop board 7 is located between the first desktop board 4 and the second desktop board. between plates 5;

2. The second working state (desk in normal state, such as a study table with drawers)

As shown in Figure 2, the third desktop board 7 in the first working state is pulled down by the vertical chute 8 until it is blocked by the boss on the vertical chute 8; and the third desktop board 7 and the second desktop board 5 is connected through the linkage mechanism 2, and the second desktop board 5 is combined with the first desktop board 4 through the horizontal chute 1 to form a complete desktop; at the same time, the linkage mechanism 2 itself has the feature of being lockable, therefore, in this working state The formed study table with drawers is more stable and convenient for study and work.

3. The third working state:
