[0031] As shown in the drawings, Figure 1 The telescopic height-adjustable stand comprises at least one telescopic rod, the number of the telescopic rods is the same as that of the layers, and the telescopic rod and the layer of the same telescopic height-adjustable stand are one-to-one opposite, and the layer is fixedly connected to the telescopic rod opposite to the layer.

It can absorb and store this impact energy, preventing the impact force from being directly transmitted to the entire splicing frame structure. At the same time, the damping rod 8 will generate damping force, which can slow down the movement speed of the impact force, making the compression and recovery process of the return spring 10 more stable, thereby reducing the vibration phenomenon of the overall device.

Then, fix the first splicing plate 4 and the third splicing plate 6 onto the corresponding telescopic height-adjustable uprights. After that, select an appropriate number of second splicing plates 5 according to actual needs, and insert the protrusion on one side of the second splicing plate 5 into the groove of the first splicing plate 4 or the previous second splicing plate 5. At the same time, insert the telescopic rod in the protrusion into the insertion connection hole. Splice in this way until the splicing of the entire shelf is completed. If it is necessary to increase the number of shelves, the above steps can be repeated at the appropriate height position. When installing new shelves, first adjust the four telescopic height-adjustable uprights according to the required height when setting up the splicing frame. Then, fix the first splicing plate 4 and the third splicing plate 6 onto the corresponding telescopic height-adjustable uprights. After that, select an appropriate number of second splicing plates 5 according to actual needs, and insert the protrusion on one side of the second splicing plate 5 into the groove of the first splicing plate 4 or the previous second splicing plate 5. At the same time, insert the telescopic rod in the protrusion into the plug connection hole. Splice the shelves in this way until the entire shelf is spliced. If you need to increase the number of shelves, you can repeat the above steps and install the new shelves at the appropriate height.
