A second groove is provided on one side of the first groove below the main table board 1, and the interior of the second groove includes:

The support assembly 5 includes an adjustable support leg 51, the lower end of the adjustable support leg 51 is fixedly connected to a support foot, and the upper ends of the two adjustable support legs 51 are commonly provided with a rotating rod 52, and the front and rear ends of the rotating rod 52 are respectively fixedly connected to the opposite side of the adjustable support leg 51, and the front and rear sides of the rotating rod 52 are respectively rotatably connected to the opposite side of the inner wall of the second groove.

A connecting piece 44 is provided at the opposite end of the two movable connecting rods 43. The opposite sides of the two connecting pieces 44 are rotatably connected together through a rotating shaft. The upper surfaces of the two connecting pieces 44 are fixedly connected to the lower surfaces of the corresponding movable connecting rods 43. The two connecting pieces 44 are arranged front and back.

An adjustment component 45 is provided inside the extension shell 41, and the adjustment component 45 includes an adjustment rod 451 connected to the threaded ring block 42. The left end of the adjustment rod 451 is rotatably connected to the left side of the inner wall of the extension shell 41. The inner wall of the threaded ring block 42 is provided with a plurality of limit blocks 452. The plurality of limit blocks 452 are evenly distributed inside the threaded ring block 42, and the opposite sides of the plurality of limit blocks 452 are fixedly connected to the inner wall of the threaded ring block 42.

During use, when the main table board 1 is used, the two main table boards 1 are folded and unfolded through the connecting piece 44, and the adjustable support leg 51 on the main table board 1 is taken out from the second groove, so that the rotating rod 52 supports the main table board 1, and the positioning block 22 on the right main table board 1 is inserted into the positioning block 22 in the left main table board 1 to keep the two main table boards 1 stable;

When the use area of the main table board 1 is insufficient, the adjusting rod 451 is rotated by the turning knob 454, and the limit block 452 in the threaded ring block 42 moves in the limit groove 453 on the adjusting rod 451, and the limit block 452 and the limit groove 453 are mutually limited. Therefore, when the adjusting rod 451 is rotated, the threaded ring block 42 can be driven to rotate, and the threaded ring block 42 rotates and moves in the extension shell 41. At the same time, the mobile connecting rod 43 slides in the annular groove in the threaded ring block 42 through the annular slider. Therefore, the mobile connecting rod 43 remains stable when moving, and the threaded ring block 42 drives the moving connecting rod 43 to move. The movable connecting rod 43 is moved. During the movement of the movable connecting rod 43, the two main table boards 1 are moved away from each other. The folding extension table board 2 is placed between the two main table boards 1. The positioning block 22 on the folding extension table board 2 is inserted into the positioning groove 21 in the left main table board 1, and the positioning block 22 on the right main table board 1 is inserted into the positioning groove 21 in the folding extension table board 2. The folding extension table board 2 is installed. At the same time, after the folding extension table board 2 is placed between the two main table boards 1, the length of the movable connecting rod 43 is adjusted so that the two main table boards 1 can clamp the folding extension table board 2, thereby reducing the gap between the two main table boards 1 and the folding extension table board 2.

When the main table panel 1 needs to be folded, the folding extension table panel 2 is removed from between the two main table panels 1, and the connecting rod 43 is moved back into the extension shell 41. At this time, the adjustable support leg 51 is folded into the second groove for storage. At the same time, the positioning block 22 on the right main table panel 1 is not inserted into the positioning groove 21 in the left main table panel 1. The two main table panels 1 are folded through the connecting piece 44, and the two main table panels 1 are put together, and the folding extension table panel 2 is placed in the storage slot 3 for storage.

Example 2

Referring to Figures 1-7, which is the second embodiment of the utility model, cavities are opened on opposite sides of the two main table boards 1, and a limit assembly 53 is arranged inside the cavity. The limit assembly 53 includes a limit gear 531 connected to the rotating rod 52, and the inner wall of the limit gear 531 is fixedly connected to the center of the rod wall of the rotating rod 52. The rotating rod 52 is arranged inside the cavity, and a limit tooth block 532 is arranged above the limit gear 531. The bottom of the limit tooth block 532 is meshed with the top of the limit gear 531. A straight sliding groove is opened on the right side of the inner wall of the cavity, and the inner wall of the straight sliding groove is slidably connected to the right side of the limit tooth block 532 through a straight sliding block.

A shift block 533 is fixedly connected to the left side of the limiting tooth block 532, and the left end of the shift block 533 passes through the left side of the inner wall of the cavity to the left side of the main table board 1. The shift blocks 533 on the left and right sides are arranged oppositely, and a plurality of return springs 534 are provided above the limiting tooth block 532. The upper and lower ends of the plurality of return springs 534 are respectively fixedly connected to the upper side of the limiting tooth block 532 and the upper side of the inner wall of the cavity.

When the adjustable support leg 51 is in use, it is necessary to move the shift block 533 to drive the limit gear block 532 to move upward. At this time, the return spring 534 is compressed, and the limit gear block 532 is separated from the restriction of the limit gear 531, so that the adjustable support leg 51 can be flipped. When one adjustable support leg 51 is started to flip, the other adjustable support leg 51 is driven to flip through the rotating rod 52. After the adjustable support leg 51 is flipped, the shift block 533 is released, and under the rebound action of the return spring 534, the limit gear block 532 is driven to press the limit gear 531 on the rotating rod 52, thereby positioning the limit gear 531 and keeping the two adjustable support legs 51 stable when in use.

The remaining structures are the same as those of Example 1.
