[0035] Working principle: When vibration occurs, the pressing cylinder 1 pushes the piston rod 3 downward. At this time, the pressing cylinder 1 deforms the spring 4, achieving the first layer of decompression. Then, the piston rod 3 pushes the piston column 5 downward in the oil cylinder 8. At the same time, the oil 13 in the oil cylinder 8 flows upward through the circular hole 6 on the piston column 5. Due to the resistance of the circular hole 6, the downward movement of the piston rod 3 is slower, achieving the second layer of shock absorption. Under the pressure of the piston rod 3, the oil cylinder 8, connected to the connecting block 9, drives the extrusion head 10 downward, squeezing the filling gas 11 in the support column 12. This causes the filling gas 11 to be compressed and pushed upward, achieving the third layer of decompression. When the pressure disappears, the filling gas 11 pushes the oil cylinder 8 upward, and the spring 4 returns to its original position, causing the pressing cylinder 1 to drive the piston rod 3 to reset. This achieves a better shock absorption effect even when high-frequency vibration occurs, and the components are less likely to be damaged.
[0036] When the threaded post 23 needs to be replaced, remove and press the threaded post 23. At this time, the connecting rod 204 inside the threaded post 23 is pressed down. The connecting rod 204 drives the stop block 205 to move downward in the small groove 207 in the disassembly cylinder 206. At this time, rotate the threaded post 23 to rotate the connecting rod 204 and the stop block 205 outward to the large groove 208. At this time, the threaded post 23 can be removed from the disassembly cylinder 206 along with the connecting rod 204 and the stop block 205. Similarly, press down the new threaded post 23 and rotate it so that the stop block 205 is stuck in the small groove 207. This achieves the effect of replacing only the threaded post 23 when the threaded post 23 becomes stripped, without replacing the whole post.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
