The outer wall of the locking block 14 is slidably connected to the inner wall of the worktable body 15.

[0027] Specifically, pulling the adjusting block 12 slides on the inner wall of the worktable body 15, while the locking block 14 sliding on the inner wall of the adjusting block 12 slides on the outer wall of the worktable body 15. When the locking block 14 compresses the second spring 13 to the appropriate position, the second spring 13 pushes the locking block 14 to lock the worktable body 15, thereby achieving a quick fixing effect.

[0029] Specifically, the motor 16 fixed to the inner wall of the workbench body 15 drives gear 17 to rotate, which in turn drives gear 2 18 to rotate on the inner wall of the workbench body 15, achieving a stable rotation effect. The rotation of gear 2 18 drives telescopic column 20 and hollow column 21 to rotate together, and the rotation of telescopic column 20 drives support block 23 to rotate, which in turn drives support column 22 to rotate. At the same time, the electric push rod 19 is activated to push support column 22 to rise and fall, thereby allowing support column 22 to drive support block 23 to rise and fall. The support column 22 can adjust the platform to a suitable height, making it easier to operate more accurately and reducing errors.

[0030] Reference Figure 4 and Figure 5 A rack 26 is slidably connected to the inner wall of the support block 23. A gear 25 is meshed with the tooth end of the rack 26. The inner wall of the gear 25 is fixedly connected to the outer wall of the support column 22. A hollow block 30 is fixedly connected to the upper surface of the lower rack 26.

A hollow block 30 is fixed on the upper surface of the lower rack 26, and support platform 1 28 slides on the upper surface of hollow block 30. Telescopic column 27 is used to connect hollow block 30 and support platform 1 28. When rack 26 drives hollow block 30 to slide, it will drive support platform 1 28 to slide on the inner wall of guide block 24, enabling support platform 1 28 to achieve stable lifting and lowering and be flush with support platform 2 29. The upper rack 26 will drive support platform 2 29 to slide, and support platform 1 28 slides on the outer wall of support platform 29 to achieve a limiting effect. The support platform 2 29 can increase the area of ​​the workbench and provide a more spacious working space.

[0032] Working principle: When the worktable is needed, pulling the adjusting block 12 allows the locking block 14 to slide on the outer wall of the worktable body 15. Once in the appropriate position, the second spring 13 pushes the locking block 14 to lock the worktable body 15, causing the adjusting block 12 to push the rotating block 11 to rotate. This allows the clamping plate 2 to rotate on the inner wall of the worktable body 15, achieving angle adjustment. Rotating the rotating column 7 causes the rotating plate 1 to rotate on the outer wall of the clamping plate 2, driving the pawl 4 to engage the ratchet 3, achieving a self-locking effect. Pulling the pull rod 6 quickly releases the self-locking effect, while the first spring 5 allows the pawl 4 to quickly reset. The rotation of the rotating plate 1 pulls the rotating rod 8, causing the slider 9 and the clamping block 10 to slide together on the outer wall of the clamping plate 2, achieving rapid centering and clamping. Starting the motor 16 drives the first gear 17 and the second gear 18 to rotate together, causing the telescopic column 20 to drive the support block 23 to rotate. The support block 23 then drives... The movable support column 22 rotates on the inner wall of the hollow column 21. Activating the electric push rod 19 pushes the support column 22 to slide and rise. The rotation of the support column 22 drives the gear 3 25 to rotate, causing the racks 26 on both sides to slide in tandem. The sliding of the lower rack 26 drives the hollow block 30 to slide. The telescopic column 27 on the inner wall of the hollow block 30 connects to the support platform 28, allowing the support platform 28 to slide on the inner wall of the guide block 24, achieving a stable sliding and rising effect. Simultaneously, the upper rack 26 drives the support platform 29 to slide, making the support platform 29 flush with the support platform 28. This workbench can not only hold different drawings and documents to prevent wrinkles, improving readability and lifespan, but also increase the workbench area, providing a more spacious workspace. Furthermore, the platform height can be quickly adjusted for more precise operation and reduced errors.
