[0002] In current application scenarios such as industrial automation, production line assembly, scientific research experiments, and warehousing logistics, three-dimensional lifting platforms, as important auxiliary equipment, are widely used to lift, move, and position various items; however, the existing designs of three-dimensional lifting platforms often have significant limitations, especially in terms of their installation methods and movement flexibility;

[0003] Specifically, many existing three-dimensional lifting platforms are designed to be fixed on one side of the wall. Although this fixed installation method ensures the stability of the equipment to a certain extent, it also greatly limits the flexibility and adaptability of its usage scenarios; in situations where frequent position changes or operations in different areas are required, such fixed-installed lifting platforms are inadequate.

[0004] In addition, in terms of moving and rotating capabilities, existing three-dimensional lifting platforms also generally have deficiencies; most products can only achieve limited horizontal movement (such as linear sliding) and rotation (usually only 180 degrees), which far from meets the diverse needs in complex working environments.

[0005] Therefore, it is necessary to provide a new three-dimensional lifting platform with adjustable rotation angle to solve the above technical problems. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides a three-dimensional lifting platform with adjustable rotation angle.

[0010] Preferably, the horizontal threaded rod and the vertical threaded rod are not at the same height, and the horizontal slide bar and the vertical slide bar are not at the same height either.

[0016] Precise rotation adjustment ability: By adopting a worm and worm gear transmission mechanism, the 360-degree arbitrary angle rotation of the connecting column and the connecting plate under the bearing platform is realized; this design not only provides a wide rotation range but also ensures the accuracy and stability of rotation, meeting the requirements for precise angle control of objects in fields such as precision machining and scientific research experiments;

[0017] Realization of the fine-tuning function: By driving the telescopic plate to expand and contract on the connecting plate through the electric push rod, the fine-tuning function of the bearing platform during rotation is realized; this design enables the device to easily achieve fine-tuning when precise adjustment of the object position or angle is required, improving the accuracy and reliability of the operation;
