Through adopting above-mentioned technical scheme, in daily use, through buffer spring 15's setting, when slider 14 slided in logical groove 12, extrusion buffer spring 15 perhaps applyed pressure to slider 14 through buffer spring 15, and the stability when making slider 14 slide in logical groove 12 obtains improving.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
