[0002] In the research and diagnosis of pathological histology, pathological tissue sectioning is a crucial technology. In related experiments on small animals, a certain size of diseased tissue will be taken and made into pathological sections using pathological histological methods. The lesions will be further examined with a microscope, and the development process of the lesions will be recorded. Finally, a pathological diagnosis will be made. Pathological tissue sectioning requires the use of corresponding equipment. China's authorized utility model patent (Announcement No.: CN220270944U) discloses a pathological tissue sectioning device, which uses a laser light beam to mark the section position, which is more intuitive and convenient for adjusting the relative position of the cutter and the pathological tissue, and is convenient for subsequent research and observation. It is convenient and practical.

[0003] Since the cutter is a consumable, it needs to be disassembled and replaced after being used a certain number of times. However, the prior art of installing the cutter seat in the groove by fastening screws has some shortcomings: when installing the cutter seat, the screw holes on the cutter seat need to be aligned with the screw holes on the lifting plate to achieve the installation of the screws. Long-term twisting can easily cause the screw holes on the lifting plate to wear and thread slippage, resulting in poor stability of the cutter seat after installation. When replacing the cutter, the screws need to be manually removed one by one, which is cumbersome and time-consuming, and requires the use of tools, which is relatively inconvenient. Therefore, a pathological tissue slicing device is proposed to address the above situation. Utility Model Content

The pair of racks 504 are both provided with positioning rods 505, and the ends of the pair of positioning rods 505 away from the racks 504 are respectively inserted into the slots on the tool holder 4.

[0035] A knob 6 is provided at the top of the driving shaft 502, and a pair of fixing blocks 7 are provided on the knob 6. A groove 701 is provided at the bottom of the fixing block 7, and a pair of springs 702 are provided in the groove 701. The bottom of the pair of springs 702 is fixedly connected with a limiting rod 703, and the limiting rod 703 cooperates with the positioning groove 5010. A T-shaped rod 704 passing through the groove 701 is provided at the middle position of the top of the limiting rod 703, and a pair of supporting blocks 705 are provided on the top of the fixing block 7.

[0036] Reference Figure 6 A pair of supporting blocks 302 are arranged in the assembly groove 301 , the bottom of the knife seat 4 is overlapped on the pair of supporting blocks 302 , and a cutting knife is arranged at the bottom of the knife seat 4 , and the cutting knife passes through the assembly groove 301 and extends to the bottom of the lifting seat 3 .

[0037] Furthermore, a pair of supporting blocks 302 supports and lifts the tool holder 4, thereby ensuring the stability of the tool holder 4 after positioning.

[0038] Reference Figure 3 and Figure 5 A through hole is formed on the top of the positioning block 501 , and the through hole cooperates with the driving shaft 502 .

[0039] Furthermore, the through hole serves as a channel for the drive shaft 502 to rotate.

[0040] Reference Figure 3Openings are provided on both sides of the positioning block 501, and the positioning rod 505 cooperates with the openings. The positioning rod 505 is in an "L" shape.

[0041] Furthermore, the positioning rod 505 moves horizontally through the opening, and then moves in and out of the slot on the knife seat 4, thereby completing the positioning and releasing of the knife seat 4.

[0042] Reference Figure 3 A pair of slide grooves are provided in the empty groove of the positioning block 501 , and a slider is slidably fitted in each of the pair of slide grooves, and the slider is fixedly connected to the rack 504 .

[0043] Furthermore, the arrangement of the slide groove and the slider ensures the stability of the horizontal movement of the rack 504 .

[0044] Reference Figure 4 A round hole is provided on the top of the fixing block 7, which cooperates with the T-shaped rod 704. A bearing is provided on the limiting rod 703, and the bottom of the T-shaped rod 704 cooperates with the inner ring of the bearing.

[0045] Furthermore, the T-shaped rod 704 can rotate on the limit rod 703, and then the T-shaped rod 704 can be rotated after pulling the limit rod 703 up, and the two ends of the T-shaped rod 704 can be overlapped on a pair of support blocks 705, so as to achieve the positioning of the limit rod 703, providing convenience for the staff to operate the knob 6.

[0046] Working principle: when installing a new tool holder 4, insert the tool holder 4 into the assembly groove 301, overlap the bottom of the tool holder 4 on the support block 302, and snap into the assembly groove 301 to complete the preliminary installation of the tool holder 4. Then turn the knob 6 to drive the drive shaft 502 to rotate. The rotation of the drive shaft 502 causes the gear 503 to rotate, and the rotation of the gear 503 causes a pair of racks 504 to move. The movement of the pair of racks 504 causes the corresponding positioning rods 505 to move, so that the positioning rods 505 extend into the slots provided on the tool holder 4, and operate another positioning mechanism 5 to complete the positioning of the pair of tool holders 4.

[0047] After the positioning is completed, at this time, the positioning rod 505 is in contact with the slot, and then, the T-shaped rod 704 is lifted up to make the T-shaped rod 704 move upward, so that the T-shaped rod 704 is separated from the support block 705, and the T-shaped rod 704 is rotated and then released. Under the reset of the spring 702, the limit rod 703 descends, and the limit rod 703 descends to make the T-shaped rod 704 descend, and then the T-shaped rod 704 is stuck between a pair of support blocks 705. At the same time, the limit rod 703 descends and extends into the positioning groove 5010, and the fixing block 7 is fixed and limited, so that the knob 6 is fixed, that is, the limiting of the drive shaft 502 is achieved.
