[0033] Please see Figure 1-8 The present invention provides the following technical solution: a multi-dimensional adjustable desk, including a desk body 1, with bases 13 connected to the bottom of both ends of the desk body 1 via telescopic support frames 12, an extension structure 2 slidably provided on the left side of the desk body 1, a first mounting groove 11 opened on the upper right of the desk body 1, a movable lifting support plate 4 installed on the first mounting groove 11, and a second mounting groove 14 opened on the upper left of the desk body 1, with a clamping mechanism 3 installed on the second mounting groove 14.

[0034] In practical use, the expansion structure 2 includes an expansion panel 21, a storage drawer 22, and a side panel 24. The left side of the storage drawer 22 is connected to the left end of the expansion panel 21 via a side panel 24. The front and rear sides of the expansion panel 21 are equipped with sliding strips 27, which slide within the storage slot 16 on the table body 1. A limiting slider 25 is installed at the bottom of the storage drawer 22, which slides on a limiting groove 17 above the inner side of the telescopic support frame 12. A temporary placement board 23 is provided at the top of the storage drawer 22. A handle 26 is installed on the outer surface of the side panel 24. When the desktop area is insufficient, the expansion panel 21 can be pulled out of the storage slot 16 via the handle 26, thereby expanding the desktop. The storage drawer 22 on the expansion structure 2 can store textbooks and documents. After pulling out the expansion panel 21, temporary documents or items can be temporarily placed on the temporary placement board 23, increasing the storage space of the table body 1.

[0035] In practical use, the clamping mechanism 3 includes a fixed clamping plate 31, a movable clamping plate 32, and a driving mechanism for driving the movable clamping plate 32 to move horizontally. The driving mechanism includes a first lead screw 35, which is installed inside the second mounting groove 14. A lead screw slide 36 is slidably mounted on the first lead screw 35. Both ends of the lead screw slide 36 slide on the slide rail 15 of the second mounting groove 14 via sliders 38. A clamping seat 37 is connected above the lead screw slide 36 via a connecting block. The movable clamping plate 32 is mounted on the clamping seat 37 via a damping shaft 39. The fixed clamping plate 31 is mounted on the left end of the second mounting groove 14 via the clamping seat 37. A cover plate 33 with a hollowed-out groove for the connecting block to move is provided above the second mounting groove 14. A groove is provided on the left end of the table 1, and a rotating wheel 34 connected to the first lead screw 35 is installed in the groove. The fixed clamping plate 31 and the movable clamping plate 32 rotate in opposite directions on the clamping seat 37 via the damping shaft 39. When it is necessary to neatly arrange textbooks or documents on the table 1, the textbooks or documents can be placed vertically against the fixed clamping plate 31, and the rotating wheel 34 can be turned to drive the first lead screw 35 to rotate, thereby driving the movable clamping plate 32 to move towards the fixed clamping plate 31 until it cooperates with the fixed clamping plate 31 to clamp and position the textbooks or documents for storage. This facilitates organization, retrieval, and quick access. When not clamping, the fixed clamping plate 31 and the movable clamping plate 32 can be flipped inward along the damping shaft 39 and closed.

[0036] In practical use, the movable lifting support plate 4 includes a second lead screw 41, a movable plate 42, a guide rod 43, an electric telescopic rod 45, and a support plate 46. The second lead screw 41 and the guide rod 43 are installed on the inner ends of the first mounting groove 11. The two ends of the movable plate 42 slide on the second lead screw 41 and the guide rod 43 through the lead screw slider 44 and the guide block. The electric telescopic rod 45 is installed in the middle of the movable plate 42, and the support plate 46 is installed at the top of the electric telescopic rod 45. The rear end of the second lead screw 41 extends out of the table body 1 and is connected to the lead screw adjustment handle 47. The support plate 46 is driven to move up and down by the electric telescopic rod 45. The support plate 46 is rotated by the lead screw adjustment handle 47. The second lead screw 41 moves back and forth on the table body 1 via the moving plate 42. In this embodiment, in the initial state of this design, the support plate 46 is retracted and embedded in the first mounting groove 11, and its upper surface is at the same level as the surface of the table body 1, maintaining the flatness of the table body 1 surface. In use, the support plate 46 is driven to rise by controlling the electric telescopic rod 45, which facilitates the adjustment of the height when placing textbooks, displays, or laptops. At the same time, the second lead screw 41 can be rotated by the lead screw adjustment handle 47 to drive the moving plate 42 to move back and forth, thereby adjusting the front and back position of the support plate 46, which facilitates the adjustment of the distance between the support plate 46 and the user, thereby protecting the user's eyesight.

[0037] The working principle and usage process of this utility model: When the desktop area is insufficient, the extension panel 21 can be pulled out from the storage slot 16 by the handle 26, thereby expanding the desktop. The storage drawer 22 on the extension structure 2 can store textbooks and documents. After pulling out the extension panel 21, temporary documents or items can be temporarily placed on the temporary placement board 23, thus increasing the storage space of the table body 1.

[0038] When it is necessary to neatly arrange textbooks or documents on the table 1, the textbooks or documents can be placed vertically against the fixed clamp 31. The rotating wheel 34 is turned to drive the first lead screw 35 to rotate, thereby moving the movable clamp 32 towards the fixed clamp 31 until it cooperates with the fixed clamp 31 to clamp and position the textbooks or documents for storage; making it convenient to organize, find and quickly retrieve; when not clamping, the fixed clamp 31 and the movable clamp 32 can be flipped inward along the damping shaft 39 and closed.

[0039] In its initial state, the support plate 46 is retracted and embedded in the first mounting groove 11, with its upper surface at the same level as the surface of the table body 1, maintaining the flatness of the table body 1. During use, the support plate 46 is raised by controlling the electric telescopic rod 45, making it easy to adjust the height when placing textbooks, displays, or laptops. At the same time, the second lead screw 41 can be rotated by the lead screw adjustment handle 47 to move the moving plate 42 back and forth, thereby adjusting the back and forth position of the support plate 46 and facilitating the adjustment of the distance between the support plate 46 and the user, thus protecting the user's eyesight.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
