[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a teaching test paper classification device, comprising a bottom plate 11, a vertical plate 14 is fixedly connected to the upper left end of the bottom plate 11, a plurality of square plates 8 are fixedly connected to the right side of the vertical plate 14, a vertical plate 2 15 is fixedly connected to the upper right end of the bottom plate 11, a plurality of square plates 8 are fixedly connected to the left side of the vertical plate 2 15, a screw rod 7 is rotatably connected inside the left square plate 8, a sliding rod 9 is fixedly connected inside the right square plate 8, a long board 10 is threadedly connected to the upper screw rod 7, a long board 3 13 is threadedly connected to the middle screw rod 7, a long board 2 12 is threadedly connected to the lower screw rod 7, a note board 18 is slidably connected to the inner sides of the front of the long boards 10, 13 and 12, and a fixing component is arranged on the middle sides of the front of the long boards 10, 12 and 13.

[0032] Specifically, when the height of long board 10 needs to be adjusted, twisting the upper rotating handle 6 will drive the upper screw rod 7 to rotate. At this time, long board 10 will slowly move up and down on the upper screw rod 7 and the upper slide bar 9. When it moves to the appropriate position, stop twisting the upper rotating handle 6. When the height of long board three 13 needs to be adjusted, twisting the middle rotating handle 6 will drive the middle screw rod 7 to rotate. At this time, long board three 13 will slowly move up and down on the middle screw rod 7 and the middle slide bar 9. When it moves to the appropriate position, stop twisting the middle rotating handle 6. When the height of long board two 12 needs to be adjusted, twisting the lower rotating handle 6 will drive the lower screw rod 7 to rotate. At this time, long board two 12 will slowly move up and down on the lower screw rod 7 and the lower slide bar 9. When it moves to the appropriate position, stop twisting and rotating the lower rotating handle 6.

[0033] Reference Figure 4 The fixed component includes a thin shell 2, the outer side of the thin shell 2 is fixedly connected to the outer middle side of the long board 10, the long board 2 12 and the long board 3 13, the inner middle side of the thin shell 2 is slidably connected with a paddle rod 4, the outer side of the paddle rod 4 is fixedly connected with a small baffle 3, and the outer side of the paddle rod 4 is sleeved with a spring 5.

[0034] Specifically, the handle 1 is pulled, and the paddle rod 4 drives the small baffle 3 to move outward, and then the small baffle 3 compresses the spring 5 until the paddle rod 4 leaves the memo board 18. At this time, the memo board 18 can be taken out, and the handle 1 is released. The spring 5 squeezes the small baffle 3, driving the paddle rod 4 to penetrate the long board 10 again and be inserted into the inside of the memo board 18, thereby facilitating the installation and removal of the memo board 18.

[0035] Reference Figure 2-Figure 3The outer side of the upper screw rod 7 is slidably connected to the inside of the long board 10, the outer side of the middle screw rod 7 is slidably connected to the inside of the long board 3 13, the lower screw rod 7 is slidably connected to the inside of the long board 2 12, the upper rear end of the bottom plate 11 is fixedly connected to the back plate 16, the outer side of the small baffle 3 is slidably connected to the inside of the thin shell 2, the paddle rod 4 is inserted into the inside of the memo board 18, the front end of the paddle rod 4 is fixedly connected to the handle 1, the lower part of the bottom plate 11 is rotatably connected to a plurality of universal wheels 17, one end of the spring 5 is fixedly connected to the middle of the small baffle 3, and the other end of the spring 5 is fixedly connected to the inner wall of the thin shell 2.

[0036] Specifically, long board 10, long board 2 12 and long board 3 13 are installed to classify and place test papers. The backboard 16 prevents the test papers from falling from the back. The universal wheels 17 can be easily moved between different locations. The handle 1 is more convenient when unloading the memo board 18, and the baffle 24 prevents the spring 5 from leaving the thin shell 2.

[0037] Working principle: twisting the rotating handle 6 will drive the screw rod 7 to rotate. At this time, the long board 10 will slowly move downward on the screw rod 7 and the sliding rod 9. When it moves to the appropriate position, stop twisting the rotating handle 6 to adapt to the cumulative thickness of test papers of different sizes, ensuring that the test papers can be smoothly and accurately identified and classified during the classification process. When it is necessary to remove the top memo board 18, pull the handle 1 to make the paddle rod 4 move outward, and then the small baffle 3 moves outward, thereby compressing the spring 5, and the paddle rod 4 leaves the inside of the memo board 18 until it leaves the long board 10. At this time, the memo board 18 can be removed. When installing the memo board 18, it is necessary to loosen the handle 1 so that the paddle rod 4 drives the small baffle 3 to move, thereby making the spring 5 return to its original position, and the paddle rod 4 passes through the long board 10 and is re-inserted into the inside of the memo board 18, so as to facilitate the installation and removal of the top memo board 18, and the middle memo board 18 and the lower memo board 18 are installed or removed in the same way.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
