The rotating lubricating sleeve 31 and the thrust bearing 32 reduce the frictional resistance encountered by the adjusting screw 3 during rotation, thereby improving the adjustment flexibility of the adjusting screw 3. Adjusting screw 3 is sleeved with an upward pressure spring 33 and a downward push spring 34. The ends of the upward pressure spring 33 abut against the inner wall of the lifting guide slot 11 and the upper end surface of the connecting protrusion 21, respectively. The ends of the downward push spring 34 abut against the inner wall of the lifting guide slot 11 and the lower end surface of the connecting protrusion 21, respectively. The springs limit the swing of the connecting protrusion 21, improving lifting accuracy. The adjusting screw 3 and thrust bearing 32 are locked with a nylon nut 35 to ensure the stability of the connection. An adjustment knob 36 is connected to the upper end of the adjusting screw 3 to facilitate rotation of the adjusting screw 3.

[0031] Example 2:

[0032] like Figure 1 and Figure 2 As shown, in order to reduce the difficulty of disassembly and assembly of the fine-tuning lifting structure, an upper placement cavity 12 and a lower placement cavity 13 are also provided on the fixed base 1. The upper placement cavity 12 is arranged above the lifting guide groove 11, and the rotating lubrication sleeve pad 31 is arranged in the upper placement cavity 12; the lower placement cavity 13 is arranged below the lifting guide groove 11, and the thrust bearing 32 is arranged in the lower placement cavity 13; the upper placement cavity 12 and the lower placement cavity 13 are both connected to the lifting guide groove 11 through the guide through hole 15, and the adjusting screw 3 is arranged in the guide through hole 15.

[0033] Example 3:

[0034] like Figure 1 and Figure 2 As shown, in order to further ensure the stability of the fine-tuning lifting structure, a cover 14 is provided at the lower end opening of the lower placement cavity 13 to prevent debris from entering and interfering with the movement of the adjustment screw 3.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
