[0035] In the embodiments of the present disclosure, as shown in the attached Figure 2 and attached Figure 3 As shown, two clamping blocks 5011 are welded on the inner edge of the hole of the lifting plate 501, and the clamping blocks 5011 are slidably clamped in the slide groove 401. A clamping strip 503 is welded inside the splicing piece 5, and two clamping grooves 5021 are opened on the same side of the splicing plate 502. Another splicing plate 502 is vertically clamped inside the clamping groove 5021. By plugging the splicing plate 502 and the clamping groove 5021 into each other, the splicing plates 502 can be spliced ​​into a U-shaped structure, and finally plugged into the slot 505, the clamping strip 503 is welded inside the splicing piece 5. The top of the strip 503 is assembled, and when the splicing board 502 is used up, it is disassembled into independent splicing boards 502 and stored in the interior of the splicing piece 5, and the card slot 5021 on the bottom splicing board 502 is snapped on the card strip 503.

After the lifting plates 501 of the two splicing members 5 are respectively clipped to the top of the threaded rod 4, the top of the lifting plate 501 is fastened by tightening the screw 402.

[0037] By rotating the splicing piece 5, the threaded rod 4 can be driven to rotate through the clamping block 5011. Since the fixed internal threaded tube 3 is fixed, the threaded rod 4 can be moved up and down when rotating through the threaded engagement to adjust the height of the splicing piece 5, ensuring that students can fully observe the teaching content that needs to be displayed. Then the bottom end of the inner spring telescopic rod 6 is inserted into the clamping hole 201, and the top end is inserted into the through hole 504 to support the splicing piece 5 for display.
