[0026] In order to support the table top 100 after it moves up and down during use, Figure 4 A cavity 600 is provided in the movable column 60 along its axial direction, and a pin rod 604 is provided in the cavity 600 and passes through the side wall of the cavity 600. A pin hole 608 is provided on the inner wall of the pillar B for inserting the pin rod 604, so that when in use, the telescopic mechanism A is controlled to extend to drive the table top 100 to move upward in the vertical direction, and then the column body 6 and the movable column 60 are controlled to extend in coordination, and the pin rod 604 is controlled to be inserted into the pin hole 608, and then the column body 6 and the movable column 60 are fixed after being extended to avoid relative movement between the column body 6 and the movable column 60. Therefore, the pillar B composed of the column body 6 and the movable column 60 is used to support the table top 100, and the telescopic mechanism A can be controlled to shrink and restore to the initial state.

[0027] The bottom ends of the support column A4 and the column body 6 are connected to the pad A41 and the pad B61 respectively.

[0028] Based on the above, in order to facilitate the control of the connection sleeve B3 and the support B during use; Figure 4-5At least one positioning rod 31 extending into the rectangular frame 1 is provided on the inner bottom side of the connecting sleeve B3, a positioning pin hole 311 is provided on one side of the positioning rod 31, a cavity 10 connected to the positioning pin hole 311 is provided on the rectangular frame 1, a telescopic module A11 is provided in the cavity 10, and a positioning plug for inserting into the positioning pin hole 311 is provided at the end of the telescopic module A11; and a rectangular chamber A is opened in one side of the rectangular frame 1, and a deformation chamber A7 connected to the telescopic module A11 is provided in the rectangular chamber A, and the telescopic module A11 includes an inner sleeve A, an outer sleeve A, and a connecting sleeve A that are sealed and sleeved with each other. A spring C is placed between the two; when the spring C is in a natural or compressed state, the positioning plug is inserted into the positioning pin hole 311; and the deformation bin A includes an inner sleeve B and an outer sleeve B which are sealed and sleeved with each other, and a spring D connected therebetween; a telescopic mechanism B for controlling the volume change of the deformation bin A is arranged in the rectangular chamber A; and when in use, when it is necessary to control the support B to be pulled out of the connecting sleeve B3, the volume of the deformation bin A is first controlled to increase, and then the telescopic module A11 is driven to shrink until the positioning plug slides out of the positioning pin hole 311, and the support B can be controlled to be pulled out of the connecting sleeve B3.

[0029] At the same time, in order to facilitate the driving pin 604 to move during use, Figure 4 A movable rod 601 is provided in the cavity 600 and moves up and down along its inner wall. The bottom side of the movable rod 601 is connected to a vertical rod 602, and the bottom end of the vertical rod 602 is connected to a movable plate 605. A spring B627 is connected between the movable plate 605 and the bottom side of the cavity 600; both sides of the vertical rod 602 are rotatably connected to a connecting plate 603, and the ends of the two connecting plates 603 are rotatably connected to the ends of two pins 604 respectively; and openings 606 for the pins 604 to pass through are provided on the opposite side walls of the cavity 600; a telescopic module B32 for driving the movable rod 601 to move downward in the vertical direction is provided on the inner top side of the connecting sleeve B3; a rectangular chamber B is also provided on one side of the rectangular frame 1, and a deformation chamber connected to the telescopic module B32 is provided in the rectangular chamber B.
