[0026] Specifically, the placement groove 2 plays a limiting role on the internal threaded rod 3, so that the threaded rod 3 can rotate smoothly. The placement groove 2 plays a limiting role on the internal threaded sleeve 4, so that the threaded sleeve 4 can slide smoothly. By rotating the threaded rod 3, the threaded sleeve 4 can move up and down stably. The fixed block 1 plays a limiting role on the lower clamping block 6, so that the threaded sleeve 4 can smoothly drive the lower clamping block 6 to move up and down, and then the two mounting plates 7 can be adjusted smoothly, thereby making the measurement more accurate. The clamping block 6 plays a limiting role on the mounting plate 7 at the right end, so that the mounting plate 7 can be directly installed inside the clamping block 6, so that the mounting plate 7 can be conveniently installed and disassembled.

[0027] Reference Figure 4 A battery 8 is installed on the left side of the interior of the mounting plate 7, and a charging head 9 is fixedly connected to the front end of the battery 8. A plurality of fill lights 10 are installed on the inner and outer sides of the mounting plate 7. The plurality of fill lights 10 are distributed in a circle and in a horizontal direction. A lens 5 is installed on the interior of the mounting plate 7, and a measuring scale 16 is provided on the outside of the lens 5.

[0028] Specifically, the mounting plate 7 provides an installation space for the internal battery 8, so that the battery 8 can be stably installed inside the mounting plate 7. The battery 8 and the fill light 10 are electrically connected, so that the battery 8 can provide power for the fill light 10, so that the fill light 10 can illuminate the lens 5 for a long time, so that the user can see the measurement scale 16 on the outside of the lens 5 more clearly, and the measurement scale 16 is distributed in a cross shape, so that the user can observe from multiple angles, and the observation is more convenient. The battery 8 can be charged through the charging head 9, so that the battery 8 has a stronger endurance.

[0029] Reference Figure 4 The pulling assembly includes two slide grooves 11, which are respectively opened on the front and rear sides of the interior of the mounting plate 7. A pull rope 12 is slidably connected inside the slide groove 11, and a spring 13 is sleeved outside the pull rope 12.

[0030] Specifically, the two slide grooves 11 are symmetrically distributed, so that the connection between the mounting plate 7 and the microscope is more stable. The slide groove 11 limits the internal pull rope 12, so that the pull rope 12 can slide smoothly. The pull rope 12 limits the external spring 13, so that the spring 13 will not deviate when it is squeezed or reset.

[0031] Reference Figure 4The clamping assembly includes two limit blocks 14, the adjacent sides of the two limit blocks 14 are respectively fixedly connected to the separated ends of the two pull ropes 12, one end of the spring 13 is fixedly connected to the inner wall of the slide groove 11, and the other end of the spring 13 is fixedly connected to the inner side of the limit block 14, and the separated ends of the two limit blocks 14 are fixedly connected with a clamping block 15, the outer part of the limit block 14 is slidably connected to the inside of the slide groove 11, and the outer part of the clamping block 15 is slidably connected to the inside of the slide groove 11, and the outer part of the clamping block 15 is clamped with the inside of the microscope.

[0032] Specifically, the slide groove 11 limits the internal limit block 14 and the clamping block 15, so that the limit block 14 and the clamping block 15 can slide smoothly, and then the slide groove 11 can stably pull the spring 13 to produce elastic deformation, and then when the spring 13 performs a reset movement, the spring 13 can push the limit block 14 to move outward, and then the limit block 14 can push the clamping block 15 to engage with the microscope, so that the installation of the mounting plate 7 is more stable.

[0033] Working principle: When the mounting plate 7 needs to be installed, the pull rope 12 is pulled to the right, so that the other ends of the two pull ropes 12 can be driven to move toward the adjacent side, and then the pull rope 12 pulls the limit block 14 to move toward the adjacent side, so that the limit block 14 can squeeze the spring 13 to produce elastic deformation, and at the same time the limit block 14 can drive the card block 15 to move inward, so that the card block 15 can slide into the inside of the slide groove 11, and then the mounting plate 7 is slid into the inside of the microscope, so as to loosen the pull rope 12, so that the spring 13 can perform a reset movement, so that the spring 13 can push the two limit blocks 14 to move toward the separated side, so that the limit blocks 14 can drive the clamping block 15 to engage with the microscope, so that the lens 5 inside the mounting plate 7 can be installed conveniently and stably, and then when the microscope is used, the lens 5 will not shake, so that the measurement accuracy is higher. When the distance between the two lenses 5 needs to be adjusted, the threaded rod 3 is rotated, so that the threaded rod 3 can drive the threaded sleeve 4 to move up and down, so that the lower clamping block 6 can move up and down, and then the lower clamping block 6 can drive the lower mounting plate 7 to move up and down, so that the two lenses 5 can be adjusted, and then the measurement accuracy can be conveniently adjusted, so as not to affect the progress of the operation.
