In order to adapt to the traction pull rod 300 with different thicknesses or other to-be-transported components with different sizes, the connection between the base 230 and the box body 100 is movably connected, and the spacing between the support wheels 210 can be repositioned by moving the base 230.

[0070] In this embodiment, the support wheel 210 can be a resin part, supporting the traction pull rod 300, avoiding damage to the rod body. The base 230 is fixed in the box body 100 by bolts, and synthetic rubber is added around the inside of the box body 100, avoiding the traction pull rod 300 from sliding out and causing harm.

[0071] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
