[0039] Specifically, no limitation is imposed on the specific shape of the column 11. Its cross-section can be a polygonal structure or a circle, as long as it can provide support. It can be understood that the central control area should match the size of the cross-section so that the column 11 can pass through the lifting platform 21.

[0040] Specifically, no limitation is imposed on the driving form of the driving motor 32. The driving motor 32 can be driven by an AC power supply, a battery, etc. Those skilled in the art can determine it according to the actual operation situation, which will not be elaborated here.

[0041] Specifically, the bending rod 41 includes a straight portion 411 connected to the column 11 at one end and a bending portion 412 arranged at the other end of the straight portion 411. A hole 413 for connecting the connecting plate 42 is arranged at the end of the bending portion 412.

[0042] Specifically, the bending rod 41 further includes a fixing bar for fixing the bending rod 41 on the column 11.

[0043] Specifically, limit blocks 311 are sleeved on both ends of the threaded rod 31 close to it. The limit blocks 311 are connected to the column 11 to limit the relative position of the threaded rod 31 and the column 11.

[0044] Specifically, the position of the limiting block 311 is not limited, and those skilled in the art can design the installation position according to actual situations, which will not be elaborated here.

[0055] Specifically, the driving shaft of the driving motor 32 is connected to one end of the threaded rod 31 through a differential 35.

[0056] Specifically, when using an overloaded Z-axis lifting system to lift heavy objects, place the heavy object on the lifting platform 21, start the driving motor 32 to drive the lifting platform 21 carrying the heavy object to start moving. At this time, the fixed block 331 cooperates with the threaded rod 31, and the lifting platform 21 rises steadily along the slide rail 12. When the heavy object is lifted to a predetermined position, the buffer spring 312 plays a buffering role at this time. Fix the hole position 413 and the connecting plate 42 to ensure that the lifting platform 21 carrying the heavy object is stable at the predetermined position, completing the heavy object lifting process. Release the fixed state of the hole position 413 and the connecting plate 42, and start the driving motor 32 until the lifting platform 21 falls back to its original position. At this time, the buffer spring 312 plays a buffering role, completing the descending process.
