[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This high aspect ratio micro-aperture optical measurement support structure features a clamping mechanism where the scale on the support rod precisely controls the height of the mounting base. Bolt one securely locks the mounting base in place, preventing loosening after height adjustment. The movable cooperation between the support arm and the crossbar, along with the locking action of bolt two, allows for flexible adjustment of the lateral distance while maintaining stability, preventing the digital microscope from shifting laterally. Bolts three on both sides of the arc-shaped gripper can be adjusted and firmly fixed according to the size of different digital microscopes, achieving compatibility with various microscope heads and significantly improving the versatility of the measurement system. Simultaneously, the secure locking of each component ensures the stability of the digital microscope's position during measurement, providing a reliable guarantee for maintaining the coaxiality of the optical system's optical axis and the sample's micro-aperture, thereby contributing to improved imaging quality and measurement accuracy.
[0013] 2. This high aspect ratio micro-aperture optical measurement support structure features a fine-tuning bracket on the fixed base, which, together with a graduated sleeve and an adjustment knob, allows for precise longitudinal fine-tuning of the connecting plate with the guidance of a limiting block and a limiting groove. The scale allows for quantifiable adjustment, ensuring accurate longitudinal position control. Similarly, the fine-tuning bracket on the fixed base, along with the graduated sleeve and adjustment knob, combined with the guidance of a limiting block and a limiting groove, enables precise lateral fine-tuning of the connecting plate. Simultaneously, the limiting rod on the inner side of the back plate, in conjunction with a spring, provides a stable elastic preload after adjustment, preventing loosening. This multi-directional, graduated, precise fine-tuning design efficiently corrects the coaxiality of the optical system's optical axis and the sample micro-aperture. Furthermore, the high stability of each component after adjustment significantly improves measurement accuracy and reliability, better meeting the precision adjustment requirements of high aspect ratio micro-aperture measurements.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1:
[0021] Based on existing technology, traditional measurement supports have the following drawbacks: the support components are prone to loosening after adjustment, making it difficult to stably maintain the coaxiality of the optical system's optical axis and the sample's micro-orifice. Furthermore, they cannot be adapted to different sizes of microscope lenses and other components, limiting the versatility of the measurement system. Please refer to [link / reference]. Figures 1-4This utility model provides a technical solution: a high aspect ratio micro-aperture optical measurement support structure, including an iron frame base 1, a displacement platform 2 fixedly installed at the center of the iron frame base 1, a fixing rod 3 fixedly installed on the top of the displacement platform 2, a placement plate 4 fixedly installed on the top of the fixing rod 3, and a sample 5 to be tested placed on the placement plate 4; the high aspect ratio micro-aperture optical measurement support structure includes a clamping mechanism and a fine adjustment mechanism, the clamping mechanism includes the iron frame base 1, a support rod 6 fixedly installed on the iron frame base 1, a scale 201 with height markings on the support rod 6, a mounting seat 202 movably installed on the support rod 6, and a bolt 203 movably installed on the left side of the mounting seat 202 via a thread.
[0022] The right side of the mounting base 202 is provided with a support arm 204. A crossbar 205 is movably installed laterally inside the support arm 204.

Bolt 208 is threadedly installed on both sides of the arc-shaped gripper 207.
[0023] The iron stand base 1 provides stable support for the entire structure. The displacement platform 2 at its center can drive the fixed rod 3 and the top placement plate 4 to move as a whole, so as to achieve coarse positioning of the sample 5 to be tested. After the sample 5 to be tested is placed on the placement plate 4, the sample micropore is roughly moved into the measurement field of view. At the same time, the support rod 6 of the clamping mechanism is vertically fixed to the iron stand base 1. The digital microscope 8 is fixed by the arc-shaped clamp 207, and its lens is aligned with the sample 5 to be tested. The computer 10 is connected to the digital microscope 8 through the data cable 9 to receive image signals and perform measurement analysis.
[0024] Mounting base 202 is fitted onto support rod 6 with scale 201. By sliding mounting base 202 and observing scale 201, the height of digital microscope 8 can be quickly adjusted to adapt to different sample thicknesses. After adjustment, tighten bolt 1 203 to lock the position and prevent loosening. Support arm 204 and crossbar 205 slide together. Pushing crossbar 205 can change the lateral distance of digital microscope 8 relative to the sample. After adjustment, bolt 2 206 is used to lock the relative position of support arm and crossbar. Arc-shaped gripper 207 is used to hold digital microscope 8. Rotate bolt 3 208 on both sides according to the lens diameter to tightly fix lenses of different specifications and ensure that there is no relative wobbling between the lens and gripper.
[0025] Example 2:
[0026] Based on Embodiment 1, when the position of the sample to be tested needs to be adjusted, the existing device relies solely on vision and senses for position adjustment, resulting in low accuracy. Therefore, this structure increases its adjustment accuracy by adding a fine-tuning mechanism. Please refer to [link to previous document]. Figures 1-4This utility model provides a technical solution: a large aspect ratio micro-aperture optical measurement bracket structure, the fine adjustment mechanism includes an iron frame base 1, a fixed base 301 is fixedly installed on the iron frame base 1, a fine adjustment bracket 302 is fixedly installed at the end of the fixed base 301, and a sleeve 303 is fixedly installed on the side of the fine adjustment bracket 302, the sleeve 303 is provided with a scale.
[0027] An adjusting knob 304 is movably installed inside the sleeve 303 via a thread. Its end passes through the sleeve 303 and abuts against the end face of the connecting plate 307. A limiting block 305 is provided in the middle part of the fixed base 301, on which the connecting plate 307 is movably installed. A limiting groove 306 that matches the limiting block 305 is provided below the connecting plate 307.
[0028] A fixed base 308 is fixedly installed on the connecting plate 307 by bolts. The fixed base 308 has a fine adjustment bracket 309 and a back plate 315 at both ends. A graduated sleeve 310 is fixedly installed inside the fine adjustment bracket 309. An adjustment knob 311 is installed inside the sleeve 310 by thread. Its end passes through the sleeve 310 and abuts against the end face of the connecting plate 313. Two sets of limit rods 316 are fixedly installed on the inner side of the back plate 315.
[0029] A limiting block 312 is fixedly installed on the fixed base 308. A connecting plate 313 is movably installed on the fixed base 308. The bottom of the connecting plate 313 is provided with a limiting groove 314 that matches the limiting block 312. The end of the connecting plate 313 is provided with a mounting groove that matches the limiting rod 316. A spring 317 is fixedly installed between the mounting groove and the back plate 315 and is sleeved on the limiting rod 316.
[0030] A computer 10 is provided on the side of the iron stand base 1. The computer 10 is connected to the digital microscope 8 via a data cable 9. The digital microscope 8 is movably installed in the arc-shaped gripper 207.
[0031] When longitudinal (along the sample height direction) fine adjustment is required, rotate the adjustment knob 304, and its end pushes the connecting plate 307 to move. The limiting groove 306 at the bottom of the connecting plate 307 cooperates with the limiting block 305 on the fixed base 301 to ensure accurate movement without deviation. The adjustment can be quantified by the scale on the sleeve 303. When adjusting laterally, the limiting groove 314 at the bottom of the connecting plate 313 cooperates with the limiting block 312 on the fixed base 308 to ensure accurate lateral movement. At the same time, a spring 317 is fitted on the limiting rod 316 of the back plate 315. One end of the spring abuts against the connecting plate 313, and the other end is fixed to the back plate 315, providing continuous preload to prevent loosening due to vibration after adjustment. The lateral adjustment amount can be quantified by the scale on the sleeve 310. The spring and other components also provide preload during longitudinal adjustment.
