At this time, since the slider is arranged opposite to the spacing guide component 4, and the slider can move laterally along the transverse guide rail 64, under the guidance of the spacing guide component, the roller 61 moves simultaneously in the guide groove 43, thereby realizing the equidistant variable distance movement of the mounting member 7.

[0023] In one embodiment, at least two groups of transverse guide rails 64 are provided in the longitudinal direction, and the two groups of transverse guide rails 64 are respectively provided with a first slider 62 and a second slider 63. The first slider 62 and the second slider 63 are staggered in the longitudinal direction and are respectively arranged opposite to the equidistant guide grooves 43 of the first group 41 and the equidistant guide grooves 43 of the second group 42.
