The output end of the motor 56 is fixedly connected to the outer wall of one end of the main shaft 57. The outer wall of the main shaft 57 is fixedly connected to a gear 58. The inner wall of the mounting belt 51 is fixedly connected to a push rod 53. The outer walls of multiple push rods 53 are meshed with the outer walls of the gear 58. The outer ring wall of the mounting belt 51 is fixedly connected to a mounting seat 52. The outer walls of multiple mounting seats 52 are fixedly connected to a toggle ball 54. A mounting groove 55 connected to the outer walls of both sides of the placement seat 2 is provided at the top. The internal rotation of the mounting groove 55 is connected to a countershaft. Another identical gear 58 is fixedly connected in the middle of the outer wall of the countershaft.

[0028] Embodiment 3

[0029] A collecting box 6 is fixedly connected to the lower part of the outer wall of one side of the support plate 61, and a scraper 63 is fixedly connected to the lower part of the support plate 61 near the upper part of the collecting box 6. The outer wall of one side of the scraper 63 is in movable contact with the outer wall of one side of the moving ball 54, and an L-shaped pull plate 62 is slidably inserted into the interior of the collecting box 6.

[0030] When the dust inside the collection box 6 is cleaned, the handle on the L-shaped pull plate 62 can be pulled, and then the handle is subjected to tension, which can drive the L-shaped pull plate 62 to leave the inside of the collection box 6, thereby cleaning the impurities inside the collection box 6, avoiding the impurities on the microsphere body 3 affecting the results of the optical fiber's detection of the microsphere body 3, and correspondingly increasing the accuracy of the detection results of the microsphere body 3.

[0031] The working principle and usage process of the present invention are as follows: when working, first, the microsphere body 3 is placed inside the placement seat 2, and then the wedge-shaped optical fiber 7 is controlled to work by the controller 4. At this time, the optical fiber emitted by the wedge-shaped optical fiber 7 has a unique wedge-shaped structure, which can more effectively guide the optical signal into the optical fiber and reduce the reflection loss of light on the interface. Then, through the setting of the detection system 73, the precise alignment and coupling between the wedge-shaped optical fiber 7 and the microspherical lens 72 are ensured, thereby realizing lossless transmission of the optical signal between the wedge-shaped optical fiber 7 and the microspherical lens 72, improving the performance stability of the entire detection device, and then through the modulation and focusing of the optical signal by the microspherical lens 72, the interaction between the light and the microsphere body 3 can be enhanced, and the detection accuracy and resolution of the system can be improved. Finally, through the setting of the detection system 73, the optical signal from the structure to the wedge-shaped optical fiber 7 is converted into a measurable electrical signal. Through the analysis and processing of the electrical signal, the information of the physical quantity or chemical quantity to be measured is extracted and transmitted to the display screen on the controller 4, thereby facilitating the detection personnel to observe the detection structure of the microsphere body 3.

[0032] By starting the motor 56 on the fixing plate 5, and then through the work of the motor 56, the main shaft 57 can drive the gear 58 to rotate, and then through the meshing connection between the gear 58 and the push rod 53, when the gear 58 rotates, the push rod 53 can be moved accordingly, and then by the movement of the push rod 53, the mounting belt 51 can drive the mounting seat 52 to rotate. The toggle ball 54 is installed on the mounting seat 52, and the toggle ball 54 can be driven to move when the mounting seat 52 rotates. The contact between the toggle ball 54 and the microsphere body 3 can be moved when the toggle ball When 54 moves, one side of the microsphere body 3 is pushed upward. When the microsphere body 3 is subjected to the thrust, the thrust can be used to rotate the microsphere body 3 inside the placement seat 2, so that the microsphere body 3 moves from the bottom to the top of the placement seat 2. By rotating the microsphere body 3, it can be ensured that the detection light can illuminate different parts of the microsphere body 3, thereby obtaining more comprehensive detection data. At the same time, by rotating the microsphere body 3, the relative position of the detection light and the surface of the microsphere body 3 can be adjusted to more accurately capture these features and reduce detection errors.

[0033] By pushing the microsphere body 3 with the toggle ball 54, the impurities on the microsphere body 3 can be adsorbed onto the toggle ball 54 through the adhesive layer connected to the surface of the toggle ball 54. When the toggle ball 54 rotates the position of the scraper 63, the impurities on the toggle ball 54 can be scraped off by the setting of the scraper 63. At this time, the scraped impurities enter the interior of the collection box 6. When the dust inside the collection box 6 is cleaned, the handle on the L-shaped pull plate 62 can be pulled, and then the handle is subjected to tension, which can drive the L-shaped pull plate 62 to leave the interior of the collection box 6, thereby cleaning the impurities inside the collection box 6, avoiding the impurities on the microsphere body 3 affecting the detection results of the microsphere body 3 by the optical fiber, and correspondingly increasing the accuracy of the detection results of the microsphere body 3.
