When the saddle structure 300 is stretched, taking the outer side of the indoor saddle axle housing 310 sleeved with the outdoor saddle axle housing 320 as an example, referring to fig. 3 and 4, the indoor saddle axle housing 310 will be exposed, and at this time, the exposed indoor saddle axle housing 310 is shielded by the saddle axle housing 330.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above are only embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
