[0035] refer to Figure 2-6 One embodiment of the present application provides a mounting frame for adjusting lenses, comprising a base 1, a plug-in opening 12, a lens base 2, a first adjusting bolt 3, a second adjusting bolt 4 and a third adjusting bolt 5; a light passage 11 is provided in the base 1, a plug-in opening 12 connected to the light passage 11 is provided on the top of the base 1, a support surface 13 is formed on the peripheral side of the plug-in opening 12, and at least two positioning holes 14 are provided on the support surface 13; the lens base 2 comprises a positioning plate 21, a mounting plate 22 is provided at the bottom of the positioning plate 21, a connecting plate 23 is provided between the positioning plate 21 and the mounting plate 22, and the positioning plate 21 and the mounting plate 22 are connected. An elastic gap 24 is formed between the mounting plate 22, and a lens 100 is connected to the bottom of the mounting plate 22; the edge of the positioning plate 21 is mounted on the supporting surface 13, and the positioning plate 21 is provided with an arc guide hole 211; the positioning plate 21 is provided with a first connecting hole 212 and a second connecting hole 213, and the mounting plate 22 is provided with a third connecting hole 221; the first adjusting bolt 3 passes through the arc guide hole 211 and is threadedly connected to the positioning hole 14; the second adjusting bolt 4 is threadedly connected to the first connecting hole 212; the third adjusting bolt 5 passes through the second connecting hole 213, and the third adjusting bolt 5 is threadedly connected to the third connecting hole 221.

[0036] In this embodiment, the number and position of the arc-shaped guide holes 211 match the positioning holes 14, and the plurality of arc-shaped guide holes 211 are arranged around the same center of a circle. The stud of the first adjusting bolt 3 guides and limits the arc-shaped guide holes 211. When the nut of the first adjusting bolt 3 is not pressed against the positioning plate 21, the lens holder 2 can be rotated so that the lens holder 2 and the lens 100 rotate circumferentially around the center of the arc-shaped guide holes 211 to adjust the circumferential setting angle of the lens 100. After that, the first adjusting bolt 3 can be tightened, and the nut of the first adjusting bolt 3 presses the positioning plate 21 against the supporting surface 13 to fix the circumferential setting angle of the lens 100.

[0037] In addition, the end of the second adjusting bolt 4 is located in the elastic gap 24 and abuts against the top surface of the mounting plate 22, and the third adjusting bolt 5 is threadedly connected to the third connecting hole 221 of the mounting plate 22, and the third adjusting bolt 5 can pull the mounting plate 22 toward the positioning plate 21, so that the top surface of the mounting plate 22 remains abutted against the end of the second adjusting bolt 4; when it is necessary to adjust the pitch tilt angle of the lens 100, the third adjusting bolt 5 can be loosened first, so that the nut of the third adjusting bolt 5 is not pressed on the positioning plate 21, and at this time, the second adjusting bolt 4 can be rotated to make the second adjusting bolt 4 move axially, so that the position of the end of the second adjusting bolt 4 changes, and then the third adjusting bolt 5 is retightened, so that the nut of the third adjusting bolt 5 is pressed on the top surface of the positioning plate 21, and the inclination angle of the mounting plate 22 relative to the positioning plate 21 changes, thereby realizing the adjustment of the pitch tilt angle of the lens 100.

[0038] It should be noted that there should be a certain gap between the third adjusting bolt 5 and the second connecting hole 213 so that the third adjusting bolt 5 will not interfere with the inner wall of the second connecting hole 213 when the third adjusting bolt 5 is tilted.

[0039] In some embodiments, the positioning plate 21, the mounting plate 22 and the connecting plate 23 may be an integrated structure, and the positioning plate 21 and the mounting plate 22 may withstand a certain elastic deformation, thereby being able to adjust the pitch and tilt angles of the mounting plate 22 relative to the positioning plate 21.

[0042] In this embodiment, a detachable sealing cover 6 is added above the mirror base 2 to shield and protect the first adjusting bolt 3, the second adjusting bolt 4 and the third adjusting bolt 5 on the mirror base 2 to prevent the first adjusting bolt 3, the second adjusting bolt 4 and the third adjusting bolt 5 from loosening due to external factors.

[0043] In some embodiments, Figure 3 As shown, a first device connection port 16 is provided at one end of the light passage 11, and a second device connection port 17 is provided at the side of the light passage 11; both the first device connection port 16 and the second device connection port 17 are provided with internal threads.

[0044] In this embodiment, the first device connection port 16 and the second device connection port 17 can be used to install various optical lenses required by the optical test system, such as attenuation lenses, etc.; Figure 1 The arrangement of Figure 6 As shown, the first device connection port 16 can be used to connect a device with an excitation light source, and the second device connection port 17 can be used to connect a device with fluorescent pigment;

[0045] In addition, cage rod connection holes 18 are arranged on the peripheries of the first device connection port 16 and the second device connection port 17. Thus, the cage rod connection holes 18 enable the mounting frame for adjusting the lens 100 of the present application to be used in a cage optical system.
