[0037] Example 1:

[0038] Please see Figures 1-5 ;

[0039] A cryostat is a biomedical instrument primarily used to prepare tissue sections for microscopic examination. It works by freezing tissue samples to very low temperatures and then slicing them into very thin sections using a precise cutting mechanism. These sections can be used in pathological studies to observe tissue structure and diagnose diseases.

[0040] During slicing, the placement of the sample and the distance between it and the cutting head require professional control. This control process necessitates manual adjustment of the sample position, and after adjustment, the controlled position needs to be limited. Therefore, this application provides a manually reciprocating drive mechanism, comprising:

[0041] The drive structure 1 includes a housing 11, a handle 12 is provided in the middle of the housing 11, and a transmission structure 2 is installed at the handle 12.

[0042] The transmission structure 2 includes a drive wheel 21, a transmission belt 22 is provided on the outer side of the drive wheel 21, a driven wheel 24 is provided at the other end of the transmission belt 22, a transmission rod 25 is provided in the middle of the driven wheel 24 and is fixed by a fixing ring 23, and a sample clamping head 26 is provided at one end of the transmission rod 25.

[0043] The outer side of the outer casing 11 has a notch, and a stop structure 13 is installed at the notch to limit the transmission structure 2.

[0044] The housing 11 of the drive structure 1 is made of cold-resistant material to adapt to the low-temperature environment of the cryostat 3 and ensure stability and durability during long-term use.

[0045] The handle 12 is located in the middle of the housing 11 and is ergonomically designed to provide a comfortable grip and reduce fatigue during operation. The handle 12 also features an anti-slip design to enhance operational safety.

[0046] The bottom of the handle 12 is connected to the transmission structure 2 via a bearing to ensure smoothness and stability during transmission.

[0047] The drive pulley 21 is driven by the rotation of the handle 12 and connected to the transmission belt 22. The transmission belt 22 is made of flexible and wear-resistant rubber to ensure that it will not wear or break during long-term use.

[0048] Driven wheel 24 and transmission rod 25: A transmission rod 25 is provided in the middle of the driven wheel 24. The transmission rod 25 is connected to the sample clamping head 26 by a mechanical connection (such as a threaded connection or a snap-fit). The length and diameter of the transmission rod 25 are precisely calculated to ensure the stability and accuracy of the sample clamping head 26 during the slicing process.

[0049] The sample clamping head 26 adopts an adjustable clamping structure, which can adapt to samples of different sizes while maintaining the stability of the samples and preventing displacement during the cutting process.

[0050] The outer side of the outer casing 11 has a notch, which makes it easy to observe the distance between the sample position and the cutting head during manual adjustment.

[0051] The stop structure 13 uses an adjustable stop block, which is fixed to the notch with bolts. The user can freely adjust the position of the stop block according to specific needs, thereby limiting the range of movement of the transmission structure 2. The surface of the stop block can be coated with an anti-slip material to ensure that it will not loosen accidentally during operation.

[0052] This manual reciprocating drive mechanism, through its precise transmission structure 2 and stop function, can effectively control the position of the sample clamping head 26, reduce errors caused by human factors, and improve the accuracy of slicing.

[0053] The combination of worm gear 14 and worm wheel enables automatic limit function. After adjusting the position, the user can ensure the stability of the sample position without additional operation, thus avoiding the possible misoperation of the traditional stop structure 13.

[0054] The use of cold-resistant materials and anti-slip design enhances the equipment's performance and safety in low-temperature environments, making it suitable for the stringent requirements of the biomedical field.

[0055] The adjustable structure of the sample holder 26 allows the device to be used with samples of different sizes, increasing its applicability.

[0056] One end of the handle 12 is provided with a rotating wheel 27. The middle part of the rotating wheel 27 is adapted to the extension shaft of the handle 12 and is used to limit the rotation range of the handle 12 in conjunction with the stop structure 13.

[0057] A connecting rod 15 is provided in the middle of the handle 12. A worm gear 14 is sleeved on the rod body of the connecting rod 15. The lower part of the worm gear 14 is adapted to the outer side of the rotating wheel 27 by a worm wheel groove.

[0058] A rotating wheel 27 is mounted at the end of the handle 12. The rotating wheel 27 is designed to precisely mate with the extension shaft of the handle 12. The outer edge of the rotating wheel 27 may employ a gear structure to ensure precise engagement with the drive belt 22 or other transmission devices.

[0059] The rotating wheel 27 allows the handle 12 to rotate within a specific range, ensuring stability and consistency during rotation by adapting to the extension shaft of the handle 12. The rotating wheel 27 can be designed as a disc with gears to enhance transmission efficiency.

[0060] A connecting rod 15 is provided in the middle of the handle 12. The connecting rod 15 is designed to have sufficient strength and durability to support the rotation of the worm gear 14 and transmit power. The connection between the connecting rod 15 and the handle 12 can be fixed by threads or snaps to ensure the stability of the connection.

[0061] The worm 14 is sleeved on the body of the connecting rod 15, and the design of the worm 14 is to fit tightly with the connecting rod 15. The threaded structure of the worm 14 is used to mesh with the groove of the worm wheel, providing precise rotation control.

[0062] The outer side of the rotating wheel 27 is provided with a worm gear groove, the design of which matches the worm 14. The presence of the worm gear groove ensures that when the worm 14 rotates, it can accurately match the worm gear, producing a smooth rotation effect.

[0063] The engagement between the worm gear 14 and the worm wheel groove allows the rotation of the handle 12 to produce a small and precise displacement, thereby enabling fine adjustments to the position of the sample clamping head 26.

[0064] The rotating wheel 27 on the handle 12, in conjunction with the stop structure 13, is used to limit the rotation range of the handle 12. The stop structure 13 may include a series of adjusting blocks or baffles, which can prevent further rotation when the handle 12 reaches a predetermined position, thereby ensuring that the sample clamping head 26 is adjusted within a preset range and avoiding exceeding the operating range.

[0065] The combination of the worm gear 14 and the worm wheel groove provides high-precision rotation control, enabling more accurate adjustment of the sample holder head 26. This design allows for minute and precise adjustments, meeting the requirements of high-precision slicing.

[0066] The cooperation between the rotating wheel 27 on the handle 12 and the stop structure 13 effectively limits the rotation range of the handle 12, preventing it from exceeding the preset position, thereby improving the safety and reliability of operation.

[0067] Because the range of rotation of the handle 12 is precisely limited, users can more easily control the position of the sample clamping head 26, reducing errors caused by improper operation and improving the ease and comfort of operation.

[0068] The materials used for the handle 12, rotating wheel 27, connecting rod 15, and worm gear 14 should have high strength and wear resistance to ensure stability and durability during long-term use and adapt to the working environment of the cryostat 3.

[0069] The coordinated design of the rotating wheel 27, worm gear 14, and worm wheel groove ensures smooth operation of the manual reciprocating drive mechanism, reduces noise and friction, and improves the user experience of the equipment.

[0070] A positioning plate 17 is provided at the connection between the handle 12 and the connecting rod 15 to support the connecting rod 15 and the handle 12.

[0071] The positioning plate 17 is disposed on the inner side of the housing 11 and is fixed to the housing 11.

[0072] A connecting shaft 16 is provided in the middle of the rotating wheel 27, and the end of the connecting shaft 16 is inserted and fixed to the middle of the driving wheel 21.

[0073] A positioning plate 17 is provided at the connection between the handle 12 and the connecting rod 15. The main function of the positioning plate 17 is to provide stable support for the connecting rod 15 and the handle 12. The positioning plate 17 is usually made of durable metal or high-strength plastic to ensure its stability during long-term use.

[0074] The positioning plate 17 is fixed to the inside of the housing 11, possibly by screws or welding. The fixing method of the positioning plate 17 to the housing 11 should ensure that there is no loosening or displacement, thereby ensuring the stability of the handle 12 and the connecting rod 15 during rotation.

[0075] A connecting shaft 16 is provided in the middle of the rotating wheel 27, which is used to connect the rotating wheel 27 to the driving wheel 21. The design of the connecting shaft 16 should be precise to ensure that the rotational torque can be transmitted smoothly and to maintain a stable connection between the rotating wheel 27 and the driving wheel 21.

[0076] The end of the connecting shaft 16 is inserted and fixed to the middle of the drive wheel 21. This insertion connection design allows the rotating wheel 27 to effectively drive the drive wheel 21, ensuring efficient operation of the transmission system. The insertion connection can be achieved through keyways, threads, or other fixing structures to ensure a robust connection and stable transmission.

[0077] The positioning plate 17 provides additional support at the connection between the handle 12 and the connecting rod 15, reducing structural loosening due to operation or long-term use. This maintains the stability of the handle 12 and the connecting rod 15 during operation, avoiding operational errors caused by component displacement.

[0078] The plug-in and fixed design of the connecting shaft 16 and the drive wheel 21 ensures that the driving force of the rotating wheel 27 can be accurately transmitted to the drive wheel 21. This precise transmission connection helps to reduce power transmission losses and improves the working accuracy of the slicer 3.

[0079] The stable support of the handle 12 and connecting rod 15, along with the precise fixing of the connecting shaft 16, makes the operation of the entire manual reciprocating drive mechanism smoother. Users can get better control during operation, reducing resistance and vibration.

[0080] The use of high-strength materials in the positioning plate 17 and connecting shaft 16 enhances the durability of the equipment and meets the requirements of long-term use. Simultaneously, the design of the fixed connecting components reduces safety hazards caused by loose parts, ensuring safety during operation.

[0082] Example 2: This application also provides a slicer 3 equipped with a manual reciprocating drive mechanism, comprising:

[0083] The slicer 3 includes a protective shell 31, and the outer side of the protective shell 31 has a through hole through which the handle 12 that makes up the drive structure 1 can pass.

[0084] The outer shell 11 that makes up the drive structure 1 is disposed on the outside of the protective shell 31 and is in contact with the outer surface of the protective shell 31.

[0085] A control panel 32 is provided on the top of the protective shell 31 for controlling the parameters of the slice.

[0086] A glass plate 33 is provided on the top of the protective shell 31 below the control panel 32 to protect the internal slices.

[0087] The overall structure of the slicer 3 includes a protective shell 31, which is mainly used to protect the internal mechanical components from the influence of the external environment. The protective shell 31 can be made of impact-resistant and corrosion-resistant materials, such as plastic, aluminum alloy or stainless steel, to ensure its stability and durability in various working environments.

[0088] The outer side of the protective shell 31 has a through hole to allow the handle 12 to pass through. The through hole is designed to be large enough to accommodate the movement of the handle 12, while preventing excessive gaps that could allow external substances to enter.

[0089] The housing 11 of the manual reciprocating drive mechanism is located outside the protective housing 31 and contacts the outer surface of the protective housing 31. This design ensures that the mechanical parts of the drive mechanism are covered by the protective housing 31, thereby avoiding interference from environmental factors on its performance.

[0090] The contact surfaces between the outer casing 11 and the protective casing 31 should have good sealing properties to prevent dust, liquids, and other substances from entering the interior of the protective casing 31, thereby affecting the normal operation of the equipment.

[0091] A control panel 32 is located on the top of the protective casing 31, used to adjust and control various parameters of the slicer 3, such as slice thickness and speed. The control panel 32 may be equipped with a display screen, buttons, knobs, etc., for convenient and precise control by the user. The design of the control panel 32 should conform to ergonomics, making it easy to operate and read.

[0092] A glass plate 33 is installed below the control panel 32 to protect the slices and mechanical parts inside the slicer 3. The material of the glass plate 33 should have good impact resistance and transparency so that the user can clearly observe the internal operation, while preventing dust, debris and other external substances from entering the equipment.

[0093] The protective housing 31 provides effective protection for the internal components of the slicer 3, preventing external environmental influences on the mechanical parts. The selection and design of materials ensure that the protective housing 31 can withstand various environmental challenges during operation, increasing the durability of the equipment.

[0094] The glass plate 33 prevents users from directly contacting the moving parts inside the slicer 3 and the slicing process, reducing potential safety risks during operation. At the same time, its transparency allows users to monitor the internal status of the equipment in real time, ensuring safe operation.

[0095] The control panel 32 integrates the parameter setting functions of the slicer 3, allowing users to easily adjust various slicing parameters, thus improving operational convenience and accuracy. The control panel 32 is positioned above the glass plate 33 for convenient operation and viewing.

[0096] The protective housing 31 is designed to allow users to easily disassemble and clean it when needed. This design helps keep the equipment clean, reduces maintenance workload, and ensures the long-term stable operation of the slicer 3.

[0097] The design of the housing 11 of the manual reciprocating drive mechanism and the protective housing 31 enhances the overall coordination of the equipment, making the external and internal structures of the slicer 3 tightly integrated, thus improving the overall stability and aesthetics of the equipment.
