When the first track 2 will move to the maximum magnitude that pedestal 1 can carry, the limited post 22 on the first track 2 can be held with commutation
One section of the left side (left side as shown in Figure 10) of pass 6 offsets, and the first track 2, which continues movement to the right, can drive reversing switch 6
Left side one end is moved to the right end (right side as shown in Figure 10 of waist-shaped hole 11 from the left end (left end as shown in Figure 10) of waist-shaped hole 11
End), since reversing switch 6 is integral piece, so reversing switch 6 integrally can be moved to right side from the left side of waist-shaped hole 11, thus
The rotation direction of driving motor 41 is further changed, so that the first track 2 and the second track 3 retraction.
Further, as shown in Figure 10, Figure 13 and Figure 14, two waist-shaped holes 11 are located at the two of driving motor 41
Side.Limited post 22 is only applied with driving force to one end of reversing switch 6 when pushing reversing switch 6 to translate, and reversing switch 6 is another
One end and limited post 22 are not in contact with the position installation in order to guarantee reversing switch 6 is correct, just needs to consider each portion during installation
The directionality of part, and by the way that waist-shaped hole 11 is arranged in the two sides of driving motor 41, it is just each without considering when to each component is assembled
The directionality of component further promotes the efficiency of assembly.
Further, as illustrated in figures 1 and 8, the interlude of reversing switch 6 is arc.Due to the both ends position of reversing switch 6
In the two sides of driving motor 41, and reversing switch 6 is integrated, and arc is set by the interlude of reversing switch 6, so that intermediate
Section can avoid the output shaft of driving motor 41.
In some embodiments of the invention, as shown in Figure 13 and Figure 14, in the first track 2 and the second track 3 at least
One is equipped with the limiting slot 23 extended along its length, and limited post 22 is located in limiting slot 23.In other words, only the first track
It is provided with the limiting slot 23 of extension length direction extension on 2, or is only provided with the extension of extension length direction on the second track 3
The limiting slot 23 extended along its length is equipped on limiting slot 23 or the first track 2 and the second track 3, wherein limit
Limited post 22 is equipped in slot 23.By the way that limiting slot 23 is arranged, allow the position of limited post 22 according to actual working environment
It is required that being set, so that lighting device 100 more can be close to the requirement of concrete application.
