The desktop 10 may be used as a main desktop for placing books, computers, and other objects, and the second desktop may be used for placing mice, keyboards, and other objects; of course, the present invention is not limited thereto, and the user can place the object according to his/her needs.

The lifting table 100 further comprises a plurality of stabilizing bars (not shown), for example. For example, 3 stabilizing rods are connected between the two bases 50, the two support rods 30, and the two sliding assemblies 20, respectively, for stabilizing the lifting table 100.

The elevating table 100 further includes a screen supporting device 70, for example, the screen supporting device 70 is disposed above the table top 10 for connecting a display device such as a display. Specifically, referring to fig. 7, the screen supporting device 70 includes, for example: the clamping part 71 can be clamped at the edge of the desktop 10, the clamping part 71 is connected with a supporting rod 72 which is vertically arranged, the supporting rod 72 is connected with an adapter rod 73 which is horizontally arranged in a shaft mode, and the adapter rod 73 can rotate relative to the supporting rod 72; the adapter rod 73 is connected with the connecting rod 74 through a shaft, and the connecting rod 74 can rotate relative to the adapter rod 73; the connecting rod 74 is connected with a screen connecting part 75 by a shaft, wherein the screen connecting part 75 can rotate relative to the connecting rod 74, and the screen connecting part 75 is used for connecting a screen such as a display or a display device such as a television.

The utility model provides a lift table 100's use for example is: two opposite ends of the table top 10 are respectively provided with a sliding component 20, of course, the sliding components 20 can also be arranged at two opposite sides of the table top 10; each sliding assembly 20 is correspondingly connected with one supporting frame 30, and each sliding assembly 20 is correspondingly matched and connected with one limiting assembly 40; the limiting part 41 of each limiting assembly 40 is disposed below the table top 10 and close to the corresponding sliding assembly 20, but the control handle 46 of the limiting assembly 40 may be disposed below the other sliding assembly 20; a base 50 is provided below each of the supporting frames 30. Further, the lifting table 100 further comprises at least 3 stable rods, and the two stable rods are respectively connected with the two bases 50, the two supporting frames 30 and the two sliding assemblies 20; still further, an expansion link 60 is connected between each supporting frame 30 and the table top 10.

The raising or lowering operation of the elevating table 100 is as follows: the two control handles 46 are respectively operated to separate the limiting parts 41 of the two limiting assemblies 40 from the adjusting parts 23 of the corresponding sliding assemblies 20, and at this time, the compressed telescopic rod 60 automatically stretches, so that the distance between the first supporting rod 31 and the table top 10 is increased, the horizontal included angle between the first supporting rod 31 and the second supporting rod 32 is increased, and further, one end of the first supporting rod 31 is caused to move relative to the second slide rail 52, and one end of the corresponding second supporting rod 32 moves relative to the first slide rail 21; accordingly, when the table top is lifted, the table top 10 needs to be pressed down to compress the telescopic rod 60, so that one end of the first supporting rod 31 moves relative to the second sliding rail 52, and the corresponding end of the second supporting rod 32 moves relative to the first sliding rail 21, thereby reducing the respective horizontal included angles of the first supporting rod 31 and the second supporting rod 32.
