The width specification of the combined side column can be flexibly set according to the actual requirement.

Wherein, the front column and the rear column respectively comprise a semi-closed or closed hollow cavity surrounded by side walls.

As shown in fig. 6, a first inner open portion 101 of the first combined side column 100 and a second inner open portion of the second combined side column 100a are oppositely disposed, a transverse connecting portion 7 is disposed in an inner space between the first combined side column 100 and the second combined side column 100a, a left end of the transverse connecting portion 7 is connected to a top end portion of the first telescopic rod 6 by a space reserved in the first inner open portion 101, and a right end of the transverse connecting portion 7 is connected to a top end portion of a second telescopic rod, which is a telescopic rod accommodated in the second accommodating space 10, by a space reserved in the second inner open portion. Specifically, a first window 401 is arranged on the plate main body 40 of the first vertical connecting portion 4, a second window is arranged on the plate main body of the second vertical connecting portion 4a, the left end of the transverse connecting portion 7 penetrates through the first window 401 to be directly connected with the top end portion of the first telescopic rod 6, and the right end of the transverse connecting portion 7 penetrates through the second window to be directly connected with the top end portion of the second telescopic rod. Of course, in other embodiments, the left end of the transverse connecting portion 7 and the top end portion of the first telescopic rod 6 may be connected together through a transition connector, the transition connector passes through the first window 401, and the left end of the transverse connecting portion 7 does not pass through the first window 401. The right end of the transverse connecting portion 7 is connected with the top end portion of the second telescopic rod through a transition connector, the transition connector penetrates through the second window, and the right end of the transverse connecting portion 7 does not penetrate through the first window 401. To sum up, the left and right ends of the transverse connecting part 7 are respectively connected to the top ends of the first telescopic rod 6 and the second telescopic rod. When the first telescopic rod 6 and the second telescopic rod vertically extend and retract, the transverse connecting portion 7 can be driven to vertically move. The transverse connecting part 7 becomes a first power output end of the first telescopic rod 6 and the second telescopic rod. In addition, the relative positions of the first telescopic rod 6 and the second telescopic rod in the transverse direction can be solidified through the connection between the transverse connecting part 7 and the first telescopic rod 6 and the second telescopic rod, so that a technical basis can be provided for further solidifying the relative positions of the first combined side column 100 and the second combined side column 100a in the transverse direction. Meanwhile, when the transverse connecting portion 7 vertically moves, the first vertical connecting portion 4 is dragged to vertically move relative to the first combined side column 100, and the second vertical connecting portion 4a is dragged to vertically move relative to the second combined side column 100 a. Of course, in other embodiments, the first vertical connection 4 may be directly connected to the first telescopic rod 6, and the second vertical connection 4a may be directly connected to the second telescopic rod. The first vertical connecting portion 4 and the second vertical connecting portion 4a become the second power output ends of the first telescopic rod 6 and the second telescopic rod.

The first storage cabinet 8 is a cabinet body having a closed storage space, the second storage cabinet 8a is a plate-shaped single-layer shelf (or a plate-shaped multi-layer shelf), and the first storage cabinet 8 and the second storage cabinet 8a are respectively connected to the first vertical connecting portion 4 and the second vertical connecting portion 4a and are connected to the first telescopic rod 6 and the second telescopic rod through the first vertical connecting portion 4 and the second vertical connecting portion 4 a. The third storage cabinet 8 is connected to the first vertical connecting portion 4 and the second vertical connecting portion 4a, the transverse connecting portion 7, and the first telescopic rod 6 and the second telescopic rod through the transverse connecting portion 7. When the first telescopic rod 6 and the second telescopic rod synchronously and vertically extend and retract, the first vertical connecting part 4, the second vertical connecting part 4a and the storage cabinets (8, 8a, 8 b) can be driven to vertically move. Wherein, the transverse connecting part 7 and the third storing cabinet 8b are a part which is combined into a whole. Specifically, the third storage container 8b is in a square column shape, the transverse connecting portion 7 and the power unit 61 are stored therein, and a top wall of the third storage container 8b is a storage layer of the third storage container 8 b. A first driver (not shown in the figure) is further arranged in the first combined side column 100 and drives the first telescopic rod 6 to vertically extend and retract, and a second driver (not shown in the figure) is further arranged in the second combined side column 100a and drives the second telescopic rod to vertically extend and retract; two shaft extension ends of the power device 61 are respectively in transmission connection with the first driver and the second driver, and then respectively drive the first telescopic rod 6 and the second telescopic rod to realize synchronous lifting action. In this way, it is advantageous to control the first vertical connecting portion 4 and the second vertical connecting portion 4a to be kept in a substantially horizontal arrangement during or after the vertical movement, and the transverse connecting portion 7 and the storage cabinets (8, 8a, 8 b) to be kept in a substantially horizontal arrangement during or after the vertical movement. In other embodiments, it is also possible that the transverse connecting portion 7 and the third storage compartment 8b are separated, and the power device 61 may be selectively disposed on the transverse connecting portion 7 or the third storage compartment 8 b.
