[0059] Example 2
[0060] The difference between this embodiment and the foregoing embodiment 1 lies in: Figure 5 As shown, in this embodiment, the damping structure where the primary shock absorbing rod 1 and the secondary shock absorbing rod 2 are inserted is composed of a hydraulic damping structure and/or a pneumatic damping structure.
[0061] Such as Figure 5 As shown, in this embodiment, the upper end of the secondary shock absorber rod 2 is correspondingly inserted into the annular cavity 6 protruding outside the lower end of the primary shock absorber rod 1, and the lower side of the annular cavity 6 is provided with a ring of annular gaps, and the annular cavity 6 The gap between the two damping rods 2 is sealed and arranged to make the annular cavity 6 form a closed chamber; the end of the secondary damping rod 2 inserted into the annular cavity 6 is provided with a radially protruding circle The annular rib 8 is formed so that the plug-in place of the secondary shock absorber rod 2 and the primary shock absorber rod 1 forms a piston cylinder structure composed of the annular rib 8 and the annular cavity 6. At the same time, the annular cavity 6 is filled with damping liquid and/or damping gas 11 to provide a damping force to the movement of the annular rib 8 in the annular cavity 6.
[0062] Through the above device, the plug-in place of the primary shock absorbing rod 1 and the secondary shock absorbing rod 2 constitutes a piston cylinder structure. Therefore, when the mutual axial displacement occurs between the secondary shock absorber rod 2 and the primary shock absorber rod 1, the annular rib 8 is acted by the damping fluid and/or the damping gas 11 to provide a buffer damping force, so that the filling The piston cylinder with the damping liquid and/or the damping gas 11 constitutes a damping member, and provides a damping force that restricts the mutual axial movement of the two-stage shock-absorbing rod and the first-stage shock-absorbing rod where they are inserted.
[0063] Similarly, the above-mentioned piston-cylinder structure in this embodiment can also be arranged where the three-stage shock absorber rod 3 and the second-stage shock absorber rod 2 are inserted into each other, and the third-stage shock absorber rod 3 and the second shock absorber rod 2 The mutual movement between them provides damping force.
[0064] In this embodiment, the damping gas 11 injected into the annular cavity 6 may be directly air, so as to use air resistance to buffer and dampen the relative displacement between the two-stage shock-absorbing rods.

In the absence of external force, the first spring 12 and the second spring 13 work together to maintain the annular rib 8 in the middle position of the annular cavity 6 to provide the annular rib 8 with a movement margin that can move up and down.
[0068] Therefore, when the mutual axial displacement between the secondary shock absorber rod 2 and the primary shock absorber rod 1 occurs, the annular rib 8 is acted by the first spring 12 or the second spring 13 to provide a buffer damping force, so that The first spring 12 and the second spring 13 constitute a damping member, which provides a damping force to the joint between the secondary shock absorber rod 2 and the primary shock absorber rod 1 to limit the mutual axial movement of the two.
