[0033] The slicing part 3 can ensure the anti-cutting effect of the structure, can avoid accidental cuts of the staff during installation or disassembly of the slicing knife 304, can ensure the safety of the structure during actual use, and can also avoid the piercing of the waste bag by the discarded slicing knife 304. The slicing knife 304 can be automatically retracted, and the safety is higher. Only after the slicing knife 304 is installed on the blade mounting seat 201, the slicing knife 304 can be extended. At the same time, the limiting shaft 202 can ensure that the slicing machine can be normally started for slicing work only after the slicing knife 304 is stably installed, so as to ensure the slicing quality and stable installation of the slicing knife 304. When the slicing knife 304 is installed, the blade guide shell 301 and the limiting shell 302 are inserted into the insertion slot at the top of the blade mounting seat 201. At this time, the limiting shaft 202 is inserted into the blade mounting seat 201 and passes through the through hole on the limiting shell 302. With the advancement of the limiting shaft 202, the bottom inclined surface of the push-out block 303 can be extruded and pushed out. At this time, the push-out block 303 can be pushed upward, the spring 305 is compressed, and the slicing knife 304 is extended.

[0034] The slicing part 3 further comprises: two plastic blocking strips 306, the bottom of the push-out block 303 is bonded with two plastic blocking strips 306 through glue; the bottoms of the two plastic blocking strips 306 are respectively extruded and fitted to the inner side of the limiting shell 302; the plastic blocking strip 306 is used to push out the blade guide shell 301 by the limiting shaft 202; when the plastic blocking strip 306 does not block the push-out block 303, the side surface of the push-out block 303 stops the limiting shaft 202. The plastic blocking strip 306 is bonded with the push-out block 303 through glue, which is a non-hard connection and can be pushed and separated under external force, and the blade guide shell 301 is no longer blocked by the push-out block 303, so the limiting shaft 202 cannot be inserted subsequently, which can prevent reuse. The plastic blocking strip 306 can be used for single limiting. After the slicing knife 304 contacts the tissue, biological contaminants are inevitably left. Conventional disinfection cannot completely remove microorganisms in the gap of the instrument, and residual tissues interfere with the staining results of new samples. The structure can improve the slicing quality, has no induction operation, has a simple structure and low cost. With the advancement of the limiting shaft 202 inserted into the through hole on the limiting shell 302, the plastic blocking strip 306 can be pushed when the bottom of the push-out block 303 slides, so that the plastic blocking strip 306 is separated from the push-out block 303 and pushed out from one side of the blade mounting seat 201. When the blade guide shell 301 is disassembled and the limiting shaft 202 is pulled out, the push-out block 303 loses the blocking of the plastic blocking strip 306, and the push-out block 303 is elastically extruded and moved downward by the spring 305. The slicing knife 304 is also retracted into the blade guide shell 301. Even if you want to reuse the slicing knife 304, the bottom inclined surface of the push-out block 303 will move downward, and the end edge of the limiting shaft 202 cannot be aligned. At this time, the side surface of the push-out block 303 will stop the limiting shaft 202, so as to ensure that the reuse is prevented.

[0035] The embodiment two is based on the embodiment one, the protection detection piece 4 includes: the protection connecting plate 401, the in-place magnet 402 and the separation switch 403, the protection connecting plate 401 is fixedly installed on the side of the installation base 101 by bolt; The in-place magnet 402 is fixedly installed on the protection connecting plate 401; The separation switch 403 is fixedly installed on the protection connecting plate 401, and the separation switch 403 is electrically connected with the power supply of the slicer; The protection piece 5 includes: the protection rotating arm 501, the protection rotating arm 501 is rotatably installed on the rotating connecting shaft 103; The in-place magnet 402 magnetically attracts the protection rotating arm 501; The separation switch 403 extrudes and adheres to the protection rotating arm 501; The protection rotating arm 501 is an iron metal structure; The protection piece 5 further includes: the acrylic cover 502, the acrylic cover 502 is fixedly installed on the protection rotating arm 501; The acrylic cover 502 is located above the slicing knife 304; The slicing knife 304 and the acrylic cover 502 are provided with a misaligned interval; The knife guard control piece 6 includes: the knife guard plate 601 and the lug plate 602, the knife guard plate 601 is slidably installed on the blade mounting seat 201; The knife guard plate 601 is used for shielding the slicing knife 304; The two lug plates 602 are fixedly installed on the bottom of the knife guard plate 601; The top of the knife guard plate 601 is a bevel chamfer structure; The lug plate 602 is an iron metal structure; The knife guard control piece 6 further includes: the tension spring 603 and the electromagnet 604, the two lug plates 602 are respectively fixedly installed with the tension spring 603, and the bottom ends of the two tension springs 603 are respectively fixedly installed on the blade mounting seat 201; The two electromagnets 604 are fixedly installed on the blade mounting seat 201, and the two electromagnets 604 are respectively aligned with the two lug plates 602; The separation switch 403 is electrically connected with the electromagnet 604;The protective piece 5 cooperates with the knife guard control piece 6 to shield and protect the slicing knife 304, so that the staff member will not be cut by the slicing knife 304 when adjusting the wax block or applying the glue solution, causing occupational exposure injury. The rotating protective arm 501 can be rotated to facilitate the staff member to adjust the rotation of the acrylic cover 502, so that the slicing knife 304 is no longer shielded, and the staff member can clean the slicing knife 304 and other work. At the same time, when the wax block needs to be adjusted, the acrylic cover 502 needs to be removed to shield the wax block, so that the wax block can be replaced normally. Otherwise, the front side of the acrylic cover 502 is shielded and the wax block cannot be removed. Through structural limitation, the slicing knife 304 is shielded and protected when the wax block is replaced. At the same time, the slicing knife 304 can be shielded by the knife guard plate 601, so that the acrylic cover 502 needs to be shielded in front of the wax block before the wax block is installed and sliced, to avoid splashing during slicing due to large feeding amount or hard tissue slicing, to prevent flying splashing, to improve the safety of use. When the wax block needs to be removed or operated in actual use, the push rod of the wax block clamping clamp of the slicing machine is located above and is shielded by the acrylic cover 502. At this time, the acrylic cover 502 needs to be rotated outward to separate the rotating protective arm 501 and the in-place magnet 402, and the separation switch 403 is no longer pressed to separate. The separation switch 403 can control the magnetic ear plate 602 of the electromagnet 604 to move upward to shield the slicing knife 304, to prevent the doctor from being cut.

[0036] The working principle of the embodiment is as follows: first, the dovetail slot on the base 101 is inserted into the dovetail block on the microtome, the base bolt 1011 is tightened to press and fit the dovetail block on the microtome for positioning, the angle adjustment block 102 can be slid to adjust the angle of the sectioning knife 304, the angle bolt 1021 is tightened for positioning, when the use position of the sectioning knife 304 needs to be adjusted, the blade mounting seat 201 is slid to adjust, and the angle bolt 1021 is tightened for positioning, when the sectioning knife 304 is installed, the blade guide shell 301 and the limiting shell 302 are inserted into the insertion slot at the top of the blade mounting seat 201, at this time, the limiting shaft 202 is inserted into the blade mounting seat 201, passes through the through hole on the limiting shell 302, and as the limiting shaft 202 is pushed in, the limiting shaft 202 can press and push out the block 303 at the bottom of the inclined surface, at this time, the push-out block 303 can be pushed up, the elastic sheet 305 is compressed, and the sectioning knife 304 is extended, at this time, as the length of the limiting shaft 202 inserted into the threaded hole on the blade mounting seat 201 increases, the limiting shaft 202 can be screwed into the threaded hole on the side of the blade mounting seat 201 and tightened, at this time, the end of the limiting shaft 202 can press the on-off switch 204 to control the power supply of the microtome to be energized, and the microtome can normally drive the sectioning operation; as the limiting shaft 202 is pushed in and inserted into the through hole on the limiting shell 302, the plastic baffle 306 can be pushed when the push-out block 303 slides at the bottom, so that the plastic baffle 306 is separated from the push-out block 303 and pushed out from the side of the blade mounting seat 201, and when the blade guide shell 301 is disassembled and the limiting shaft 202 is pulled out, at this time, the push-out block 303 loses the shielding of the plastic baffle 306, and the push-out block 303 is reset downward under the elastic pressure of the elastic sheet 305, and the sectioning knife 304 is also retracted into the blade guide shell 301, and even if the sectioning knife 304 is reused, at this time, when the limiting shaft 202 is inserted, the push-out block 303 moves downward, and the bottom inclined surface cannot be aligned with the edge of the end of the limiting shaft 202, at this time, the side of the push-out block 303 stops the limiting shaft 202, so that reuse is prevented, when the wax block needs to be disassembled or operated, because the lever of the wax block clamping clamp of the microtome is located above, the doctor is in front of the acrylic cover 502, and is shielded by the acrylic cover 502, at this time, the acrylic cover 502 needs to be turned outward to remove the shielding, so that the protection rotating arm 501 and the on-position magnet 402 are separated, and the on-off switch 403 is also not pressed, the on-off switch 403 can control the magnetic attraction of the electromagnet 604 to the ear plate 602, so that the knife guard plate 601 moves upward to shield the sectioning knife 304, and the doctor is prevented from being cut, and for the same reason, when the acrylic cover 502 does not shield the front side of the wax block to prevent splashing, at this time, the knife guard plate 601 shields the sectioning knife 304, and the sectioning work cannot be normally performed, the protection rotating arm 501 needs to be turned to be magnetically attracted to the on-position magnet 402, and the on-off switch 403 is also pressed, so that the electromagnet 604 is de-energized, the knife guard plate 601 can be pulled downward by the tension spring 603, and the sectioning knife 304 is not shielded, so that the sectioning work can be normally performed.
