In addition, the limiting column can also be arranged outside the shock absorbing spring 7.

[0030] The combined tie rod 2 includes a tie rod body and a first connection structure at both ends of the tie rod body. The lower plate 5 is provided with a second connection structure matching the first connection structure provided at the end of the combined tie rod 2. The first connection structure can be detachably connected to the second connection structure. Specifically, in this embodiment, the first connection structure is a pin 3 perpendicular to the central axis of the tie rod body, and the second connection structure is a socket 51.

[0031] It should be noted that the combined pull rod 2 can also be designed as a flexible pull rod whose length or curvature can be slightly changed.
