The manual lift 3 itself has two upper and lower flanges, the lower flange can be fixed to the lower support plate 2 with screws, and the upper flange can be fixed to the upper support plate 4 with screws. The upper flange and the lower flange are connected by a partition. The manual lift 3 is fixed to the lower support plate 2 with screws, and the screw holes installed on the lower support plate 2 according to the set angle layout realize the multi-angle and multi-position installation of the equipment, ensuring the alignment with the different working conditions required by the upper end assembly of the FXT focusing mirror. The upper end assembly of the FXT focusing mirror is used for optical alignment with the lower end assembly 6 of the equipment.

[0022] The set angle layout is used for optical alignment with the upper assembly of the FXT focusing lens. Several sets of additional threaded holes are set on the upper support plate 4. According to the actual situation of focal length measurement, which set of threaded holes is installed is selected. The bottom plate of the lower support plate 2 is installed with a liftable support 1.
