However, the angular adjustment range of the second base 30 in the embodiment shown in fig. 4 is smaller than that of the second base 30 in the embodiment shown in fig. 1, so that the second base 30 can rotate relative to the first base 10 preferably by the engagement of the protrusion 36 and the through hole.
For ease of understanding, the same reference numerals are used in the embodiment shown in FIG. 4.
In some embodiments, the second base 30 is reciprocally movably disposed at the first base 10 along the second direction.
