Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, an adjustable material rack includes a support rod 1; a placement plate 12 is slidably connected to the inner side of the support rod 1; a first groove is formed inside the placement plate 12; a threaded screw 13 is rotatably connected inside the first groove; the threaded screw 13 is rotatably connected to the placement plate 12; a movable plate 14 is threadedly connected to the surface of the threaded screw 13; the movable plate 14 is slidably connected to the first groove; a limiting rod 15 is fixedly connected to the side of the movable plate 14; a limiting hole 16 is formed on the side of the support rod 1; and the limiting rod 15 and the limiting hole 16 are connected... A sliding connection is made, with a first adjusting plate 17 slidably connected to the top of the placement plate 12. A first adjusting bolt 18 is threadedly connected to the inside of the first adjusting plate 17. A first positioning hole 19 is provided on the top of the placement plate 12, and the first positioning hole 19 is threadedly connected to the first adjusting bolt 18. During operation, when the height of the placement plate 12 needs to be adjusted, the handles at both ends of the threaded screw 13 are rotated. The threaded screw 13 drives the moving plate 14 to move towards the center, which in turn drives the limiting rod 15 to move, separating it from the limiting hole 16. After the four limiting rods 15 separate from the corresponding limiting holes 16, the placement plate 12 can be moved up and down. Then, the positive and negative thread screws 13 are reversed to drive the limiting rods 15 into the corresponding limiting holes 16 to position the height-adjusted placement plate 12. When the position of the first adjusting plate 17 needs to be adjusted, the first adjusting bolt 18 inside the first adjusting plate 17 is rotated to separate it from the first positioning hole 19 at the bottom. The first adjusting plate 17 can be pulled to slide on the top of the placement plate 12. Then, the first adjusting bolt 18 is inserted into the corresponding first positioning hole 19 to position the first adjusting plate 17. This step can simultaneously drive the four limiting rods 15 to separate from the limiting holes 16 by rotating the positive and negative thread screws 13, which is convenient for adjusting the height of the placement plate 12 and positioning it. The distance between the two placement plates 12 can be adjusted. The first adjusting plate 17 can be positioned by the first adjusting bolt 18. By moving the first adjusting plate 17, the space for placing objects on the top of the placement plate 12 can be adjusted, increasing the space for placing objects and the applicability of the placement plate 12.

[0024] like Figure 3 and Figure 4As shown, the first adjusting plate 17 has a first sliding groove 21 inside, and a slider 22 is slidably connected inside the first sliding groove 21. A second adjusting plate 23 is fixedly connected to the side of the slider 22, and a second adjusting bolt 24 is threadedly connected inside the slider 22. A second positioning hole 25 is opened at the bottom of the first sliding groove 21, and the second adjusting bolt 24 is threadedly connected to the second positioning hole 25. During operation, when it is necessary to adjust the position of the second adjusting plate 23, the second adjusting bolt 24 is rotated to separate it from the second positioning hole 25 at the bottom. Then, the second adjusting plate 23 can be moved left and right to adjust its position. Finally, the second adjusting bolt 24 is rotated again to connect it to the corresponding second positioning hole 25 to position the second adjusting plate 23. This step, by setting the second adjusting plate 23, can divide the space on top of the placement plate 12 where materials are placed, and the position of the second adjusting plate 23 can be adjusted to increase the range of space division.

[0025] like Figure 3 As shown, a baffle 31 is fixedly connected to the top of the placement plate 12, and the baffle 31 is slidably connected to the first adjusting plate 17. During operation, when the first adjusting plate 17 moves, it moves inside the baffle 31. This step can protect the two sides of the placement plate 12 through the baffle 31 to prevent materials from falling from the two sides of the placement plate 12.

[0026] like Figure 1 and Figure 5 As shown, a second sliding groove 41 is provided on the side of the support rod 1, and the limiting rod 15 is slidably connected to the second sliding groove 41. A reinforcing rod 42 is fixedly connected to the inner side of the support rod 1. During operation, when the limiting rod 15 is separated from the limiting hole 16, a part of the limiting rod 15 is still inside the second sliding groove 41. The second sliding groove 41 can limit the placement plate 12 through the limiting rod 15. This step can increase the stability of the placement plate 12 when the limiting rod 15 moves through the second sliding groove 41, and the stability of the bottom of the four support rods 1 can be increased through the reinforcing rod 42.

[0027] like Figure 2 As shown, a slide rod 51 is fixedly connected inside the first groove, and the slide rod 51 is slidably connected to the moving plate 14; this step can increase the stability of the moving plate 14 when it moves.

[0028] like Figure 4 As shown, a reinforcing block 61 is fixedly connected to the side of the second adjusting plate 23, and the reinforcing block 61 is slidably connected to the first adjusting plate 17. During operation, when the second adjusting plate 23 moves, it drives the reinforcing block 61 to move. This step can support both sides of the second adjusting plate 23 through the reinforcing block 61, increasing the stability of the second adjusting plate 23 when it moves.

[0029] Working principle: When the height of the placement plate 12 needs to be adjusted, rotate the handles at both ends of the threaded screw 13. The threaded screw 13 drives the moving plate 14 to move towards the center. The moving plate 14 drives the limiting rods 15 to move, separating them from the limiting holes 16. After the four limiting rods 15 are separated from their corresponding limiting holes 16, the placement plate 12 can be moved up and down. Then, reverse the threaded screw 13 to drive the limiting rods 15 into their corresponding limiting holes 16, positioning the placement plate 12 for height adjustment. When the limiting rods 15 are separated from their limiting holes 16, a part of the limiting rods 15 remains inside the second slide groove 41. The second slide groove 41 can limit the placement plate 12 through the limiting rods 15. When the position of the first adjusting plate 17 needs to be adjusted, rotate the first adjusting bolt 18 inside the first adjusting plate 17 to separate it from the first positioning hole 19 at the bottom. The first adjusting plate 17 can then be pulled to slide on the top of the placement plate 12. Then, insert the first adjusting bolt 18 into the corresponding first positioning hole 19 to position the first adjusting plate 17. When the position of the second adjusting plate 23 needs to be adjusted, rotate the second adjusting bolt 24 to separate it from the second positioning hole 25 at the bottom. Then, the second adjusting plate 23 can be moved left and right to adjust its position. Finally, rotate the second adjusting bolt 24 to connect it to the corresponding second positioning hole 25 to position the second adjusting plate 23.
