[0027] Furthermore, by placing the lens above the support block 311, the clamping rings 34 on both sides move in opposite directions under the elastic force of the return spring 36 according to the size of the lens, which facilitates fitting and pressing against both sides of the lens, promoting stability. When the clamping rings 34 move, they drive the slider 35 to slide on the outer surface of the sliding rod 33, which in turn drives the threaded rod 38 to move and slide inside the moving groove 37. After the position of the clamping rings 34 is adjusted, the rotating fixing sleeve 39 is used to move it on the outer surface of the threaded rod 38 and abut against the inner wall of the moving groove 37, fixing the position of the clamping rings 34 and promoting the stable placement of the lens.

[0028] Example 2

[0029] like Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a support block 311 is fixedly installed at the top center of the support platform 31. Engaging grooves 312 are provided around the support block 311. An abutment block 313 is fixedly installed on the bottom end of the inner wall of the engagement groove 312.
