[0029] The specific implementation method is as follows: after the guide frame is moved to an appropriate position, the rotating rod 47 can be rotated according to the position. At this time, the rotating rod 47 will drive the sprocket wheel 46 to rotate. Under the action of the toothed chain, the sprocket wheel 46 on the worm 45 will drive the worm 45 to rotate. At this time, the rotation of the worm 45 will cause the worm wheel 44 to drive the bidirectional threaded rod 41 to rotate in the mounting sleeve 43. Under the action of the thread, the expansion plate 42 will move to the outside of the fixed plate 48. After the expansion plate 42 moves to an appropriate position, the rotating rod 47 is stopped, and then the expansion plate 42 is fixed by bolts.

[0031] The specific implementation method is as follows: When the support column 2 vibrates during use, it will drive the support plate 33 to vibrate under the damping of the damper 32. At this time, the damper 32 will reduce the vibration frequency of the support plate 33, thereby reducing the vibration frequency of the support column 2. While the support plate 33 vibrates, it will move on the outer surface of the limit column 35. At this time, the shock-absorbing spring 34 will also play a shock-absorbing effect.

At this time, the rotation of the worm 45 will cause the worm gear 44 to drive the bidirectional threaded rod 41 to rotate in the mounting sleeve 43. Under the action of the thread, the expansion plate 42 will move towards the outside of the fixed plate 48. After the expansion plate 42 moves to an appropriate position, stop rotating the rotating rod 47, and then fix the expansion plate 42 with bolts. When the support column 2 vibrates during use, it will drive the support plate 33 to vibrate under the damping of the damper 32. At this time, the damper 32 will reduce the vibration frequency of the support plate 33, thereby reducing the vibration frequency of the support column 2. While the support plate 33 vibrates, it will move on the outer surface of the limit column 35. At this time, the shock-absorbing spring 34 will also play a shock-absorbing effect.
