[0044] In some embodiments, the first support segment 121 and the second support segment 122 may be integrally formed to save manufacturing steps and effectively improve the overall structural strength of the support structure 12. Alternatively, in other implementations, the first support segment 121 and the second support segment 122 may be formed separately and then welded or clamped together.

[0045] In some embodiments, the support structure 12 and the guide rail body 1 may be integrally formed to save manufacturing steps and effectively improve the overall structural strength of the guide rail body 1.
