The limiting post 120 is clamped inside any one of the positioning holes to realize the adjustment of different heights of the height adjustment tube 4, that is, to realize the adjustment of the height of the table board 5.

[0023] The rotating arm 6 includes a movable rotating arm 61 inserted at the end of the support tube 7 and a limiting rotating arm 62 inserted at the top of the height adjustment tube 4. The movable rotating arm 61 and the limiting rotating arm 62 are coaxially arranged. The movable rotating arm 61 and the limiting rotating arm 62 are rotationally connected by a pin shaft 63 and a gasket 66. A sleeve 68 is connected to the inner center position of the limiting rotating arm 62. An angular limit gear 65 is slidably mounted on the outer wall of the sleeve 68. Inner teeth 612 that cooperate with the angular limit gear 65 are provided on the inner walls of both the movable rotating arm 61 and the limiting rotating arm 62. When it is necessary to adjust the angle of the tabletop 5, the angular limit gear 65 is driven to engage only with the inner teeth 612 on the movable rotating arm 61. When locking the angle of the tabletop 5, the compression spring 64 drives the angular limit gear 65 to retract, so that it engages with both the inner teeth 612 on the movable rotating arm 61 and the inner teeth 612 on the limiting rotating arm 62.

[0024] A counterbore 611 is provided at the outer center position of the movable rotating arm 61. The gasket 66 is installed inside the counterbore 611. One end of the pin shaft 63 passes through the gasket 66 and the counterbore 611 and is installed inside the sleeve 68.

[0025] A turntable is rotatably mounted on the inner wall of the limiting rotating arm 62. The sleeve 68 is connected to the turntable. A rotary switch button 67 is rotatably mounted on the outer side of the limiting rotating arm 62. A hook 610 is integrally formed on the rotary switch button 67. A through hole 69 is provided on the turntable. One end of the hook 610 passes through the through hole 69 and is clamped on the angular limit gear 65, which is convenient for pushing the angular limit gear 65 to move.

[0026] A compression spring 64 is connected between the inner wall of the movable rotating arm 61 and the inner side wall of the angular limit gear 65. The compression spring 64 is used to push the angular limit gear 65 to reset.

[0027] The base 1 is a U-shaped base. The foot tube 3 is perpendicular to the base 1. A plurality of brake wheels 2 are installed at the lower end of the base 1. The brake wheels 2 have a self-locking function. The self-locking function is a prior art and will not be elaborated here.

[0028] A cup holder 8 is clamped on the outer wall of one group of the height adjustment tubes 4, which is convenient for placing a teacup.

[0029] During use, the overall height of the foot tube 3 and the height adjustment tube 4 can be adjusted through the adjustment assembly 100, and then the height of the tabletop 5 can be adjusted, which is suitable for people of different heights. When the reflected light is dazzling due to the light shining on the computer screen on the tabletop 5, the angle of the tabletop 5 can be adjusted through the rotating arm 6. The specific operation is as follows:

[0030] First, press the rotary switch button 67 to move the hook head 610 inside the through hole 69, and the hook head 610 pushes the angle limit gear 65 to slide on the sleeve 68, and the angle limit gear 65 squeezes the compression spring 64, so that the angle limit gear 65 is completely engaged with the internal teeth 612 on the movable rotating arm 61 and does not engage with the internal teeth 612 on the limiting rotating arm 62. Then, rotate the rotary switch button 67 to drive the angle limit gear 65 to rotate, and then drive the movable rotating arm 61 to rotate, so as to adjust the angle of the table board 5. After adjustment, release the rotary switch button 67, and under the elastic force of the compression spring 64, push the angle limit gear 65 to reset, that is, the angle limit gear 65 is engaged with the internal teeth 612 of the movable rotating arm 61 and the internal teeth 612 of the limiting rotating arm 62, so as to lock the table board 5. At this point, the angle adjustment of the table board 5 is completed.
