The sixth sliding member 26 is a sliding rail, please refer to fig. 7, and fig. 7 is an enlarged view of position vii in fig. 4.

The sixth sliding member 26 extends in the second direction, and the lower end of the second vertical adjustment fixing plate is formed with an engaging block 25b, and the engaging block 25b is slidably engaged with the sixth sliding member 26 so that the engaging block 25b and the sixth sliding member 26 can slide relatively in the second direction. Wherein, the fitting block 25b is formed with a threaded hole 25c, and the fitting of a bolt (not shown) with the threaded hole 25c causes the front end of the bolt to abut against the sixth sliding member 26, so that the fitting block 25b is fixed relative to the sixth sliding member 26, thereby realizing the manual control and adjustment of the position of the second light source 14b in the second direction.
