[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] A multifunctional desk and chair storage space expansion device, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a secondary plate 1, a main plate 2, a rotating handle 3, a baffle 4, a first lead screw 6, a first moving block 7, a connecting block 8, a support plate 9, a spring 12, a locking tooth 13, a worm gear 14, a worm 15, and a clamping assembly. The main plate 2 is rotatably connected to the upper part of the secondary plate 1. The baffle 4 is rotatably connected to the upper left part of the main plate 2. The first lead screw 6 is rotatably connected to the middle of the secondary plate 1. The first moving block 7 is threadedly connected to the first lead screw 6. The first moving block 7 is slidably connected to the secondary plate 1. The connecting block 8 is connected to the right side of the first moving block 7. The rotating handle 3 is slidably connected to the front of the connecting block 8, the secondary plate 1, and the main plate 2. All parts are equipped with anti-slip textures for easy gripping. The connecting block 8, the sub-plate 1, and the main plate 2 are all connected to the adjacent rotating handle 3 by springs 12. The first moving block 7 is rotatably connected to the support plate 9. The right side of the support plate 9 has four object placement slots for placing small objects, and the left side of the support plate 9 has a book placement slot for placing books. The rear of the rotating handle 3 is connected to the locking teeth 13. The main plate 2, the baffle 4, and the support plate 9 are all engaged with the adjacent locking teeth 13. The lower part of the first lead screw 6 is connected to the worm gear 14. The lower front part of the sub-plate 1 is rotatably connected to the worm 15. The worm 15 and the worm gear 14 mesh with each other. The right side of the main plate is equipped with a clamping component.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the clamping assembly includes a clamping plate 5, a second lead screw 10, and a second moving block 11. The second lead screw 10 is rotatably connected to the right side of the main board 2. A knob is provided on the lower side of the second lead screw 10 for easy gripping. The second lead screw 10 is rotatably connected to the main board 2. The second moving block 11 is threadedly connected to the second lead screw 10. The second moving block 11 is slidably connected to the main board 2. The clamping plate 5 is connected to the right side of the second moving block 11.

[0024] When using this device, first place the auxiliary plate 1 next to the desk or chair, so that the edge of the desk or chair is between the clamping plate 5 and the main plate 2. Then rotate the second lead screw 10, so that the second moving block 11 moves upward under the action of the thread, driving the clamping plate 5 to move upward, so that the main plate 2 is fixed to the edge of the desk or chair. The auxiliary plate 1 is supported by contacting the ground. Then, books or other utensils can be placed on the main plate 2. If it is clamped on the chair, the main plate 2 can provide a support seat for other people, increasing the usable area, or less frequently used books can be placed in the book placement slot on the support plate 9, and small items can be placed in the item placement slot. When this device is fixed to the desk, the baffle 4 can limit the books or other items. When it is fixed to the chair, it can provide armrest support for the user. Thus, the baffle 4 can limit the books or other items or provide armrest support for the user, making it flexible to use.

[0025] When the device needs to be stored, the worm gear 15 can be rotated. The worm gear 15 meshes with the worm wheel 14, causing the first lead screw 6 to rotate. This causes the first moving block 7 to move upward under the action of the thread, which in turn moves the connecting block 8 and the support plate 9 upward. Then, the rotating handle 3 is moved forward, causing the locking teeth 13 to move forward. The spring 12 is compressed and contracted. Then, the main board 2, the baffle 4, and the support plate 9 are rotated and retracted. After retraction, the rotating handle 3 is released, the spring 12 returns to its original state, and the locking teeth 13 move and reset to engage with the main board 2, the baffle 4, and the support plate 9 respectively, locking the main board 2, the baffle 4, and the support plate 9. This allows for easy rotation, unfolding, and folding, facilitating storage of books and objects, providing seat support, and increasing the usable area of ​​the desk.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
