The telescopic rod 13 provides height adjustment for the device. A plurality of T-shaped grooves 16 are opened on the outside of the storage box 1, and the T-shaped grooves 16 are used for fixing or supporting other components. Fixing components are arranged at the four corners of the storage box 1.

[0032] Referring to Figure Figure 3 , the fixing component includes a fixing column 17, and the fixing column 17 is used to support the structural stability and load-bearing capacity of the entire display stand. A rotating rod 18 is rotatably connected to the outside of the fixing column 17, and the rotating rod 18 is used to adjust the position or angle of some components of the display stand. A support column 19 is fixedly connected inside the rotating rod 18, and the support column 19 provides additional support and stability. A non-slip pad 20 is fixedly connected to the bottom of the support column 19, and the non-slip pad 20 is used to prevent the display stand from sliding or moving on the ground, increasing the stability and safety of the display stand.
