[0042] In this embodiment, the installation stability and reliability of the wedge block 6 on the side surface of the vertical plate 4 are effectively ensured, and the inclined surface 61 effectively guides the shoelace 20 outward.

[0043] The center shafts of the self-weight wheels 7 are each provided with a wheel seat 71 after penetrating through the vertical grooves 41. The two side wheel seats 71 are jointly provided with a connecting plate 72, which effectively ensures the synchronous upward movement and downward movement of the two self-weight wheels 7.
