[0043] The inventor found through analysis of the prior art that the existing fixing device can usually only fix the sample at a single position or angle, and cannot realize multi-angle and multi-direction observation. When observing the sample, the researcher often needs to manually adjust the position of the sample or re-fix it, which is not only cumbersome to operate, but also may cause damage to the sample or inaccurate observation results. Secondly, the existing fixing device lacks flexibility and accuracy in the adjustment process, especially when fine-tuning the sample angle or position, it is often difficult to quickly and accurately complete the operation.

[0044] In the embodiments of the present application, in order to solve the problems of fixing the sample at a single position or angle, manually adjusting the position of the sample, and being unable to accurately adjust the angle in the prior art, the present application provides a solution of the theta-axis rotation module 304, specifically: comprising a microscope module 2 and a specimen fixing structure 3 connected with the microscope module 2; the specimen fixing structure 3 comprises a sample 301 rotation assembly, a sample 301 fixing seat, a theta-axis module fixing plate 218, and a theta-axis rotation module 304 for rotating the specimen; the sample 301 rotation assembly is connected with the sample 301 fixing seat, one side of the sample 301 fixing seat is connected with the theta-axis rotation module 304, and the side of the sample 301 fixing seat away from the sample 301 rotation assembly is provided with the theta-axis module fixing plate 218; the theta-axis module fixing plate 218 forms a first preset angle with the horizontal plane; the sample 301 rotation assembly forms a second preset angle with the horizontal plane; when the microscope module 2 is started, the theta-axis rotation module 304 drives the sample 301 rotation assembly to rotate on the surface of the sample 301 fixing seat. The theta-axis rotation module 304 solves the problems of fixing the sample at a single position or angle, manually adjusting the position of the sample, and being unable to accurately adjust the angle. The specimen fixing structure 3 is composed of the sample 301 rotation assembly, the sample 301 fixing seat, the theta-axis module fixing plate 218, and the theta-axis rotation module 304. This design enables flexible adjustment of the sample at multiple angles, thereby meeting the demand for multi-angle observation. The sample 301 rotation assembly is connected with the sample 301 fixing seat and is driven by the theta-axis rotation module 304, so that the sample can rotate on the surface of the sample 301 fixing seat. This rotation mechanism not only avoids the tedious operation of manually adjusting the sample, but also improves the accuracy and efficiency of adjustment. The theta-axis module fixing plate 218 forms a first preset angle with the horizontal plane, and the sample 301 rotation assembly forms a second preset angle with the horizontal plane. This angle design further expands the observation range of the sample, enabling researchers to comprehensively observe and analyze the sample from different perspectives. In addition, the introduction of the theta-axis rotation module 304 enables precise rotation adjustment of the sample in a fixed state, avoiding sample damage or observation errors caused by manual adjustment of traditional fixing devices. This automated adjustment method not only improves the convenience of operation, but also significantly improves the accuracy and reliability of the observation results. The structure of the present application successfully solves the problems of fixing the sample at a single position or angle, manually adjusting the sample, and inaccurate observation, and provides a more efficient, accurate, and flexible solution for microscope sample observation.

[0046] Below, one microscope sample fixing device in the example embodiment of the present application will be further explained.

[0047] In an embodiment of the present application, the theta axis module fixed plate 218 is at a first preset angle with the horizontal plane, and the first preset angle is in the range of 10 degrees to 80 degrees. Preferably, the first preset angle is 45 degrees; the first preset angle can be 10 degrees; the first preset angle can be 20 degrees; the first preset angle can be 30 degrees; the first preset angle can be 50 degrees; the first preset angle can be 60 degrees; the first preset angle can be 70 degrees; the first preset angle can be 80 degrees.

[0048] As an example, the theta axis module fixed plate 218 is at a 45-degree angle with the flat bottom light source 203. The theta axis module fixed plate 218 is provided on the side of the sample 301 fixed seat away from the sample 301 rotation subassembly.

[0049] In an embodiment of the present application, the sample 301 fixed seat is connected to the theta axis rotation module 304 on one side, and when the microscope module 2 is started, the theta axis rotation module 304 drives the sample 301 rotation subassembly to rotate on the surface of the sample 301 fixed seat.

[0050] In an embodiment of the present application, the theta axis rotation module 304 includes a hand screw nut 401, a stepper motor 402, a terminal block 407, and a transmission assembly. The hand screw nut 401 is connected to the stepper motor 402, and the output end of the stepper motor 402 is connected to the transmission assembly. The transmission assembly is arranged inside the sample 301 fixed seat, the stepper motor 402 is arranged on one side of the sample 301 fixed seat, and the terminal block 407 is arranged side by side with the stepper motor 402.

[0051] In a specific embodiment, the theta-axis rotation module 304 includes a hand nut 401, a stepper motor 402, a terminal block 407, and a transmission assembly. The hand nut 401 is connected to the stepper motor 402 for manual fine adjustment of the rotation angle, providing a flexible operation mode. The stepper motor 402 serves as the driving core, and its output end transmits power to the sample 301 rotation assembly through the transmission assembly, achieving precise rotation control. The high-precision characteristics of the stepper motor 402 ensure the stability and accuracy of sample rotation, while the terminal block 407 is used to connect external power supply and control signals to provide power and instructions for the stepper motor 402.

[0052] In an embodiment of the present application, the transmission assembly includes a coupling 403, a worm 404, a circlip 406, a worm wheel 409, and a bearing assembly. The output end of the stepper motor 402 is connected to the worm 404 through the coupling 403, the worm 404 is engaged with the worm wheel 409, and the end of the worm 404 away from the coupling 403 is provided with the circlip 406 and the bearing assembly.

[0053] In a specific embodiment, the transmission assembly includes a coupling 403, a worm 404, a circlip 406, a worm wheel 409, and a bearing assembly. The output end of the stepper motor 402 is connected to the worm 404 through the coupling 403, the coupling 403 functions to transmit power and compensate for the slight deviation between the motor and the worm 404, ensuring the smoothness of transmission. The worm 404 is engaged with the worm wheel 409, forming a high-efficiency reduction transmission mechanism that can convert the high-speed low-torque output of the stepper motor 402 into low-speed high-torque rotary motion, thereby meeting the accuracy and force required for sample rotation. The end of the worm 404 away from the coupling 403 is provided with the circlip 406 and the bearing assembly, the circlip 406 is used to fix the position of the worm 404 to prevent its axial movement, and the bearing assembly supports the rotation of the worm 404 to reduce friction and wear, ensuring the long-term stable operation of the transmission system.

[0054] Through the above design, the present application realizes multi-angle and high-precision rotation observation of the sample under the microscope, solves the problems of inconvenient adjustment and single observation angle of traditional fixed devices, and provides a more efficient and reliable solution for scientific research and industrial detection.

[0055] In an embodiment of the present application, the bearing assembly includes a first bearing 405, a second bearing 411, and a third bearing 412. One end of the circlip 406 is provided with the first bearing 405, the other end of the circlip 406 is provided with the second bearing 411, and the third bearing 412 is arranged between the second bearing 411 and the sample 301 rotation assembly.

[0056] In a specific embodiment, the bearing assembly includes a first bearing 405, a second bearing 411, and a third bearing 412, which collectively form a high-efficiency and stable support system to ensure the smooth operation of the transmission assembly and the accuracy of sample rotation. One end of the snap spring 406 is provided with the first bearing 405, which mainly serves to support one end of the worm gear 404 and reduce the frictional resistance during rotation. The other end of the snap spring 406 is provided with the second bearing 411, which works in conjunction with the first bearing 405 to further fix the position of the worm gear 404, preventing it from shifting axially or vibrating during rotation, thereby ensuring the stability and accuracy of the transmission. In addition, the third bearing 412 is arranged between the second bearing 411 and the sample 301 rotation assembly. The third bearing 412 serves to provide additional support for the sample 301 rotation assembly, ensuring its smooth rotation and avoiding shaking or deviation due to uneven force or external interference. The presence of the third bearing 412 not only enhances the rigidity of the entire transmission system, but also further improves the accuracy and reliability of sample rotation.

[0057] Through the coordinated action of the first bearing 405, the second bearing 411, and the third bearing 412, the bearing assembly of the present application can effectively share the load during transmission, reduce friction and wear, and prolong the service life of the equipment.

[0058] In an embodiment of the present application, the sample 301 rotation assembly is connected to the sample 301 fixed seat, and the sample 301 rotation assembly includes a fixed turntable 410, a connecting column 303, and a fine needle 302 for fixing the sample 301; the fixed turntable 410 is internally provided with a rotation scale; the fine needle 302 is connected to the fixed turntable 410 through the connecting column 303; and the fixed turntable 410 is connected to the sample 301 fixed seat. The rotation scale is a 360-degree scale that can accurately indicate the angle of rotation of the fixed turntable 410.

[0059] In a specific embodiment, in an embodiment of the present application, the sample 301 rotation assembly is connected to the sample 301 fixed seat, which is designed to achieve high-precision rotation and multi-angle observation of the sample. The sample 301 rotation assembly includes a fixed turntable 410, a connecting column 303, and a fine needle 302 for fixing the sample 301, which collectively form a flexible and precise sample rotation system.

[0060] In a specific embodiment, the fixed turntable 410 is the core component of the sample 301 rotation assembly, and has internal rotation scale lines. These scale lines are distributed in the form of 360-degree full-circle scale, which can accurately represent the angle of rotation of the fixed turntable 410. Through the rotation scale lines, researchers can intuitively read the angle information of the sample rotation, thereby achieving precise angle control and recording, which provides an important guarantee for the repeatability and accuracy of experimental data. The thin needle 302 is connected to the fixed turntable 410 through the connecting column 303. The thin needle 302 is designed to directly fix the sample, and its slender structure can minimize the obstruction to the sample, ensuring a clear view during microscopic observation. The connecting column 303 serves as a connecting bridge between the thin needle 302 and the fixed turntable 410, providing stable support and transmitting power during rotation to ensure that the sample rotates synchronously with the fixed turntable 410. The fixed turntable 410 is connected to the sample 301 fixing seat, and this connection allows the sample 301 rotation assembly to be stably fixed on the microscope platform while maintaining the flexibility of rotation. The rotation of the fixed turntable 410 is driven by the θ-axis rotation module 304, which achieves precise angle adjustment through transmission components such as the worm 404 and the worm gear 409. The 360-degree design of the rotation scale table allows the sample to be positioned and observed at any angle, greatly expanding the observation range and application scenarios of the microscope.

[0061] As an example, the rotation scale lines of the fixed turntable 410 are combined with the stepping motor 402 of the θ-axis rotation module 304, further improving the accuracy of angle control. Researchers can achieve precise rotation of the sample through manual fine-tuning (such as turning the nut 401) or automatic control (such as the stepping motor 402), meeting different experimental needs.

[0062] In the embodiments of the present application, the connecting column 303 includes a trapezoidal column and a cylindrical column; one end of the trapezoidal column is connected to the thin needle 302, and the other end of the trapezoidal column is connected to the cylindrical column; the end of the trapezoidal column connected to the thin needle 302 is provided with a needle groove for fixing the thin needle 302.

[0063] In the embodiments of the present application, the sample 301 rotation assembly is at a second preset angle with the horizontal plane; the value of the second preset angle is in the range of 100 degrees to 170 degrees.

[0066] In an embodiment of the present application, the bottom of the XY moving platform is provided with a fixing base 205; the area of the fixing base 205 is greater than the bottom area of the XY moving platform. The fixing base 205 is used for laying the device on the desktop.

[0067] In an embodiment of the present application, the fixing base 205 is provided with a wire outlet clamp 207 for fixing the wire; the wire outlet clamp 207 is in a wave shape. This wave-shaped design can better clamp the wire, prevent the wire from loosening or falling off, and at the same time can also adapt to wires of different diameters, providing more stable fixing effect. The wave shape can also increase the friction between the wire outlet clamp 207 and the wire, further improving the fixing effect.

[0068] In an embodiment of the present application, the XY moving platform is internally provided with the planar bottom light source 203, one side of the XY moving platform is provided with the X-axis horizontal displacement module 204, and the other side of the XY moving platform is provided with the Y-axis horizontal displacement module. The X-axis horizontal displacement module 204 and the Y-axis horizontal displacement module are arranged vertically.

[0069] In a specific embodiment, in order to better align the sample 301 with the optical axis of the three-dimensional microscope 217, better rotate freely around the axis of the three-dimensional microscope 217, and ensure that the sample 301 is coaxial with the three-dimensional microscope 217, the bottom platform is designed as an XY moving platform, which can realize X-axis single movement, Y-axis single movement, and XY comprehensive linkage. The X-axis horizontal displacement module 204 is composed of an X-axis stepping motor, a ball screw, a guide rail, a sensor, and a serial port connector. The Y-axis horizontal displacement module is composed of a Y-axis stepping motor, a ball screw, a guide rail, a sensor, a serial port connector, and a related connection and fixing plate.

[0070] As an example, the XY moving platform is internally integrated with the planar bottom light source 203. One side of the platform is equipped with the X-axis horizontal displacement module 204, and the other side is equipped with the Y-axis horizontal displacement module. These two modules are arranged vertically, allowing the platform to be accurately positioned and moved in a two-dimensional plane. The X-axis horizontal displacement module 204 controls the movement of the platform along the horizontal X-axis direction, while the Y-axis horizontal displacement module controls the displacement along the vertical Y-axis direction. This structural design allows the XY moving platform to move independently or synchronously in two perpendicular directions, enabling precise positioning of any point on the work surface.

[0071] In an embodiment of the present application, a planar bottom light source 203 fixing plate is arranged between the XY moving platform and the planar bottom light source 203. The planar bottom light source 203 fixing plate is arranged between the XY moving platform and the planar bottom light source 203. The main function of this fixing plate is to ensure that the planar bottom light source 203 is stably installed on the XY moving platform, thereby maintaining the stability of the light source and the accuracy of the position during platform movement. The design of the planar bottom light source 203 fixing plate takes into account the precise docking between the light source and the moving platform, as well as the protection of the light source during the entire movement process, avoiding light source deviation or damage caused by vibration or displacement. Such structural design helps to improve the stability and reliability of the entire system, ensuring that the planar bottom light source 203 can provide uniform and stable illumination during precise operation or detection.

[0072] In an embodiment of the present application, the X-axis horizontal displacement module 204 is provided with a base column assembly on the side away from the XY moving platform, which includes an upper base column 211, a lower base column 206, and a microscope connecting seat 212.
