Spring 317 is set on the outer wall of connecting strip 312 near the top. The outer wall of inner stabilizing tube 33 is slidably connected to control ring 318. There is a large friction between the inner wall of control ring 318 and the outer wall of inner stabilizing tube 33, and it can produce a damping effect. By setting the friction, it is ensured that the height of control ring 318 relative to inner stabilizing tube 33 will not change when the operator does not move control ring 318. The auxiliary rod 4, outer stabilizing tube 31 or outer tube 21 that are close to each other in two adjacent devices can be fixed by clamps and screws. The method of fixing the construction frame by clamps and screws is the prior art and is well known to those skilled in the art, so it will not be described in detail here.

[0040] Working principle: When it is necessary to adjust the height of the frame plate 1 to raise it, the operator first inserts the long rod that matches the shape of the groove of the control block 211 into the groove inside the control block 211, and then rotates the long rod, so that the control block 211 drives the control ball 25 to move in the arc groove 24.

[0041] When the control ball 25 moves, since the middle tube 22 and the outer tube 21 can only move up and down relative to each other, the control ball 25 cannot drive the middle tube 22 to rotate. Also, since the control ball 25 is inside the control groove 23, the control ball 25 can push the inner wall of the control groove 23 during its movement, thereby forcing the control groove 23 to be at the same horizontal position as it. Because the control groove 23 is pushed, it can move up and down under the push of the control ball 25, thus ensuring that the area at the same horizontal position as the control ball 25 is at the same height as it.

[0042] After the inner tube 22 moves to the top position, the staff inserts the long rod into the groove outside the control block 29 in the same way, and then the control block 29 and the control ball 210 drive the inner tube 27 to move upward to the highest position it can move.

[0043] When both the middle tube 22 and the inner tube 27 have moved to their highest positions, the inner tube 27 causes the frame plate 1 to move upward during its movement. As a result, the frame plate 1 causes the inner stabilizing tube 33 and the middle stabilizing tube 32 to move upward and reach their highest positions.

[0044] When both the middle stabilizing tube 32 and the inner stabilizing tube 33 have moved to their highest positions, the locking block 314 enters the locking groove 315 under the elastic force of the spring 317 and the pushing force of the connecting bar 312, and the insert block 35 enters the interior of the slot 316 under the elastic force of the spring 39, thereby ensuring the stability of the equipment during use.

[0045] When the equipment is finished and the upper part needs to be disassembled, and the equipment height needs to be lowered to facilitate disassembly, the staff first moves the control ring 318 downward, so that the control ring 318 presses the trapezoidal block 313, so that the trapezoidal block 313 drives the connecting strip 312 to move towards the inner side of the inner stabilizing tube 33, so that the locking block 314 leaves the slot 315.

[0046] At this time, the staff lowered the height of the inner tube 27 relative to the middle tube 22 by rotating the control block 29.

[0047] When the inner stabilizing tube 33 is lowered to its lowest position, the bottom end of the inner stabilizing tube 33 contacts the extrusion block 38, causing the extrusion block 38 to move downwards. This causes the triangular position of the extrusion block 38 to enter the interior of the triangular groove 36, causing the insertion block 35 to move towards the inner stabilizing tube 33 under the pressure of the extrusion block 38, thus leaving the slot 316. At this time, the operator can reduce the relative height between the outer tube 21 and the middle tube 22 by rotating the control block 211.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
