Specific implementation method:

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The optical pinhole seat includes a pinhole clip 6, which is fixed on a fixed tube, which is fixed in a tube sleeve 5, which is located in a mounting hole in the middle of a mounting seat 1. The mounting seat 1 is hollow inside, and an adjusting plate is slidably connected inside the mounting seat 1. There are two adjusting plates, which are connected by a clamping screw 7. An adjusting wheel 8 is rotatably connected between the two adjusting plates. One side of the adjusting plate is connected to a vertical adjusting structure 3 that is slidably connected on the mounting seat 1, and the adjacent side of the adjusting plate is connected to a horizontal adjusting structure 2 that is slidably connected on the mounting seat 1.

[0026] A slide groove is arranged on the side of the mounting seat 1, and a slider 21 is slidably connected in the slide groove. The vertical adjustment structure 3 includes a vertical adjustment screw rod 31 which penetrates the slider 21 and is rotatably connected to the slider 21, and the vertical adjustment screw rod 31 is threadedly connected to the adjustment piece.

[0027] The lateral adjustment structure 2 includes a gear shaft 22 that penetrates the slider 21 and is rotatably connected to the slider 21 . The gear shaft 22 is meshed with a tooth surface 23 in the mounting seat 1 . The gear shaft 22 is rotatably connected to the adjustment plate.

[0028] The side surface of the adjusting wheel 8 is a concave arc surface, and the radius of the concave arc surface is the same as the radius of the outer wall of the sleeve 5. The sides of the adjusting wheel 8 and the sleeve 5 are respectively provided with matching anti-slip patterns 511.

[0029] The end of the adjusting wheel 8 is fixedly connected to a rotating shaft 82 , and the rotating shaft 82 is rotatably connected to the adjusting piece. A spring 81 is sleeved on the rotating shaft 82 .

[0030] A truncated cone-shaped placement groove is arranged inside the pinhole clip 6 , a gasket ring 53 is arranged in the placement groove, and the placement groove is connected to the fixing ring 51 .

[0031] When in use, place the optical pinhole in the placement groove so that the pinhole is as coaxial as possible with the placement groove. After padding the gasket 53, use the fixing ring 51 and the fixing screw 52 to fix the optical pinhole. Then, insert the placement groove of the connecting tube sleeve 5 into the through hole on the mounting base 1, so that the sides of the tube sleeve 5 are respectively in contact with the adjusting wheel 8, and the clamping screw 7 is rotated by the hexagonal wrench. The clamping screw 7 drives the pinhole clip 6 to move toward each other. In this process, since the clamping screw 7 is rotatably connected to the upper pinhole clip 6 and the bottom is threadedly connected to the lower pinhole clip 6, and the upper pinhole clip 6 is threadedly connected to the vertical adjustment screw rod 31, the other ends of the two pinhole clips 6 are connected by the sliding rod 71, which can move the lower pinhole clip 6 upward, so that the two pinhole clips 6 can support the tube sleeve 5 from top to bottom, and the sides are supported by the adjusting wheel 8. Then, the mounting base 1 is fixed to the optical instrument by bolts, and the tube is adjusted according to the position of the object to be tested on the testing table. The sleeve 5 is adjusted laterally by rotating the knob 24. The gear shaft 22 coaxially fixedly connected to the knob 24 rotates, and the gear shaft 22 rolls relative to the gear surface 23, which can make the pinhole clip 6 move laterally. The vertical adjustment structure 3 and the adjusting wheel 8 connected to the pinhole clip 6 move laterally with it. When adjusting the vertical position, the vertical adjustment screw rod 31 is rotated, and the vertical adjustment screw rod 31 drives the pinhole clip 6 to move vertically. During this process, the lower part of the gear shaft 22 slides vertically relative to the pinhole clip 6, and the insertion rod 41 slides vertically with the top of one of the rotating shafts 82. The two ends of the rotating shaft 82 are rotatably connected to the pinhole clip 6 and supported by the spring 81, so that a smaller gap can be generated between the two pinhole clips 6 to facilitate the insertion and axial movement of the sleeve 5. When adjusting the longitudinal position, the insertion rod 41 in the longitudinal adjustment structure 4 is rotated to rotate the adjusting wheel 8, thereby changing the longitudinal position of the sleeve 5. The adjustment structure is simple, and all knobs 24 are located on the same side, which is convenient for adjustment.
