The support arm 2, the secondary support 5 and the mounting surface form a triangular structure. The stability of the triangular structure is used to achieve the stability of the support arm 2 and the installation stability of the optical devices above it.

[0028] In this embodiment, limiting components 6 are fixedly provided on both sides of the top of the fixed base 1. The limiting components 6 are used to at least limit the downward rotation of the main support arm 2 along the fixed base 1.

The fixing seat 61 is fixed on the outer wall of the top of the base plate 11, and a long screw 62 is threaded into one side of the fixing seat 61. The bottom end of the long screw 62 abuts against the upper surface of the extension plate 21. After adjusting the angle of the main support arm 2, the long screw 62 is screwed to make the bottom end of the long screw 62 abut against the extension plate 21, thereby limiting the downward rotation of the main support arm 2.
