The working principle of the first embodiment of the scheme is as follows: when the auxiliary equipment for pathological examination of liver cancer tissues, which is convenient to use, is used, a pathological sample 34 is placed between the two groups of supporting plates 38, the pathological sample 34 can be supported by arranging the L-shaped supporting plates 38, the screw rod 36 is rotated by hands, and due to the fact that the directions of threads on the left side and the right side of the screw rod 36 are opposite, the screw rod 36 is rotated to drive the two groups of sliding blocks three 37 to move oppositely on the inner walls of the sliding seats three 31, so that the two groups of supporting plates 38 are driven to move oppositely, the outer wall of the pathological sample 34 is gradually clamped, and the pathological sample 34 is prevented from deviating during cutting to influence the cutting precision;
after the pathological sample 34 is fixed, the driving motor 5 is started, the belt 6 is driven to rotate through the rotation of the output shaft of the driving motor 5, the connecting shaft 10 is further driven to rotate, the bogie 9 is driven to rotate synchronously through the rotation of the connecting shaft 10, the sleeve 11 is driven to rotate synchronously when the bogie 9 rotates, the end, away from the sleeve 11, of the push rod 12 is further driven to move up and down, the bottom end of the push rod 12 is movably connected with the upper surface of the connecting plate 13, the connecting plate 13 and the cutting knife 14 can move up and down periodically under the pushing of the push rod 12, and the sliding block I15 is further driven to slide up and down on the inner wall of the sliding seat I16;
in the initial state, the distance between the lower surface of the cutting knife 14 and the upper surface of the pathological sample 34 is the same as the thickness of the helical gear disc 26, so that the cutting knife 14 needs to fall for a certain distance to contact with the upper surface of the pathological sample 34;
during the period, the first slider 15 moves downwards to drive the connecting rod 19 to move downwards synchronously, so as to drive the second slider 18 to slide on the inner wall of the second sliding seat 17, in an initial state, the shifting rod 24 is positioned above two groups of inclined teeth of the inclined gear disc 26, when the second slider 18 moves downwards, the first rotating shaft 22 and the first rotating plate 21 are driven to move downwards synchronously, so as to drive the shifting rod 24 to be inserted between the two groups of inclined teeth of the inclined gear disc 26, at the moment, the right side of the rotating plate 21 is blocked by the top of the inner wall of the groove 20, the counterclockwise rotation cannot occur, the torsion spring 23 cannot deform, at the moment, the shifting rod 24 presses the upper surface of one group of inclined teeth of the inclined gear disc 26, at the moment, the inclined teeth are pressed by the shifting rod 24 and then transmit a group of thrust to the inclined gear disc 26, so as to drive the inclined gear disc 26 to deflect counterclockwise by taking the second rotating shaft 25 as an axis by a certain angle;
when the helical gear disk 26 rotates counterclockwise, the smooth surface of the projection 41 is pressed, so that the projection 41 is driven to slide downward on the inner wall of the limiting seat 40, and the spring 42 is pressed, and at this time, the projection 41 does not block the helical gear disk 26 from rotating counterclockwise;
the bevel gear disc 26 rotates anticlockwise to drive the rotating shaft II 25 and the gear 27 to synchronously rotate anticlockwise, so as to drive the rack 28 meshed and connected with the gear 27 to move forwards for a certain distance, further drive the sliding rod I29 to slide forwards on the inner wall of the sliding groove I30, further drive the sliding seat III 31 to slide forwards, further drive the sliding rod II 32 to slide forwards on the inner wall of the sliding groove II 33, and further push the pathological sample 34 to move forwards for a certain distance, so that the pathological sample 34 is just positioned right below the cutting knife 14;
at the moment, the cutting knife 14 continues to move downwards to cut the surface of the pathological sample 34 into pieces, the cut pathological sample 34 falls to the upper surface of the conveying belt 4, meanwhile, the output shaft of the driving motor 5 drives the driving roller 2 to rotate, further drives the driven roller 3 and the conveying belt 4 to rotate, the pieces falling to the upper surface of the conveying belt 4 are conveyed into the warm water tank 39, and the pieces naturally flatten the slightly-wrinkled wax tape on the water surface in the warm water tank 39 by means of the tension of water and the temperature of the water, so that a worker can take out the wax tape by using a glass slide in the following process;
when the shifting rod 24 is displaced to the position below the bevel gear disc 26, the next group of inclined teeth on the surface of the bevel gear disc 26 are displaced to the position of the pushed upper group of inclined teeth, and when the cutting knife 14 moves upwards, the shifting rod 24 is driven to move upwards in the same way, and at the moment, the vertical surface of the convex block 41 can block the bevel gear disc 26 from deflecting clockwise, so that the bevel gear disc 26 can only rotate in a single direction;
at this moment, the deflecting rod 24 starts to deflect by taking the first rotating shaft 22 as an axis under the extrusion action of the lower surface of the inclined teeth of the inclined gear disc 26, and meanwhile, the torsion spring 23 is compressed, so that the deflecting rod 24 returns to the initial position again under the condition that the inclined gear disc 26 does not continuously deflect, and further, the pathological sample 34 is pushed forward by a certain distance in advance once falling, and the equidistant slicing function of the pathological sample 34 is realized.
The principle of the second embodiment is different from that of the first embodiment in that the supporting plate 38 is replaced by a clamping plate 43, and the second embodiment operates according to the following principle: place pathological sample 34 between two sets of grip blocks 43, through setting up "U" shape grip block 43, can support pathological sample 34, rotate screw rod 36 with the hand, because screw rod 36 left and right sides screw thread opposite direction can drive three 37 inner walls phase motion at three 31 of slide when rotating screw rod 36, and then drive two sets of grip blocks 43 phase motion, carry out the centre gripping to pathological sample 34's outer wall gradually, prevent pathological sample 34 off tracking when the cutting, influence cutting accuracy.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
