[0020] From the above description, it can be seen that the beneficial effect of the utility model is that: by driving the multiple transmission shafts 6 at the same time through the driving motor 5, the synchronous operation of the multiple spiral lifts 7 is realized, and the synchronous lifting of the lifting push rod 8 is ensured, thereby providing a smooth and consistent lifting action, significantly improving the stability and safety of the movable stand, the lifting base 4 and the slidably mounted lifting frame 3, optimizing the overall structure, reducing the tilting or shaking that may occur during the lifting of the stand, and improving the comfort and sense of security of the audience.

[0021] Furthermore, a contact top plate connected to the lifting frame 3 is provided on the top of the lifting push rod 8 .

[0022] It can be seen from the above description that by providing a contact top plate on the top of the lifting push rod 8, the connection stability between the lifting push rod 8 and the lifting frame 3 is enhanced, and the stability during the lifting process is further ensured.

[0034] It can be seen from the above description that the damping member in the lifting hole 41 provides a buffer mechanism by abutting against the lifting upright rod 31 , which can absorb the impact during the lifting process and reduce noise and vibration.

[0035] Furthermore, the damping element is made of rubber.

[0036] From the above description, it can be seen that the damping member made of rubber material provides a more effective buffering and shock absorbing effect due to its good elasticity and shock absorption performance, thereby extending the service life of the lifting mechanism.
