By clamping the limiting plate between the top plate and the bottom plate and tightening the connecting bolt, the limiting plate and the connecting blocks at the outer sides of the first support bracket and the second support bracket are all threadedly connected through the connecting bolt, so as to prevent the shock-absorbing assembly between the first support bracket and the second support bracket from falling off during transportation.
[0033] In some examples, the bottom plate is symmetrically arranged up and down about the center line of the supporting column to strengthen the supporting force of the first supporting base as a whole.
[0034] In some examples, the connecting bolt is relatively threadedly connected to the connecting block and the limiting plate, and the connecting bolt is symmetrically arranged up and down about the center line of the limiting plate. By tightening the connecting bolt, the connection between the limiting plate and the connecting block is more stable.
[0035] In some examples, the above-mentioned limit plates are arranged at equal intervals on the first support bracket, and the limit plates are relatively engaged with the bottom plate and the top plate. The limit plates are engaged with the top plate and the bottom plate to prevent the first support bracket and the second support bracket from sliding during transportation.
[0036] In some examples, the longitudinal section of the above-mentioned limit frame is "L" shaped, and the limit frame is relatively engaged with the protective ring. The limit frame is arranged so that the protective ring can be just inside the limit frame when installed, which plays a role in limiting the position of the protective ring.
[0037] 2- Second support bracket
[0038] The inner end of the second support bracket is installed with a second friction disc, and a shock-absorbing assembly is arranged inside the second friction disc.

After the limit plate is unlocked, the structure that needs to be damped and shock-absorbing is installed on the top plate and the bottom plate, and the slider at the outer end of the connecting rod slides with variable curvature inside the first friction disc and the second friction disc.
[0039] In some examples, the slider is slidably connected to the first friction disk and the second friction disk, and the slider is symmetrically arranged up and down about the center line of the connecting rod. The slider is symmetrically arranged about the connecting rod, so that the slider can slide with both the first friction disk and the second friction disk, thereby improving the stability during damping and shock absorption.
[0040] In some examples, the first friction disc is relatively engaged with the first support bracket, and the left and right ends of the first friction disc are semicircular structures. Semicircular structures are arranged at the outer ends of the first friction disc and the second friction disc, so that the slider rebounds after contacting them, which plays a role in limiting the movement range of the slider.
[0041] In some examples, the positioning blocks are arranged at equal angles with respect to the center of the top plate, and the top plate is arranged symmetrically up and down with respect to the center line of the load-bearing column.
