The threaded holes in the first and

second shoes

11, 12 also need to pass through the internally fixed bent plates. However, because the strip-shaped connecting plate is made in a split manner, the first bottom support 11 and the second bottom support 12 need to be connected into a whole through the connecting piece 13. The connecting member 13 may be a rigid connecting member, and should have a certain strength. In this embodiment, the connecting member 13 may be made of the same plastic material as the first and second bottom supports, and the three components are integrally formed.
