[0031] Example 2
[0032] like Figure 1-3As shown, the slide bar 102 is slidably connected to the slot 101, and the L-shaped plate 103 is fixedly connected to the slide bar 102. The L-shaped plate can limit the cutting end of the pathological slice and be flush with the initial end of the ruler 208 to improve the measurement accuracy. The L-shaped plate 103 is fixedly connected to the slide bar 102, and the L-shaped plate 103 can be pulled to the right after the slicing work is completed, so that the slice can be easily taken out, which improves the convenience of use. The first slider 105 is slidably connected to the first slide groove 104, and the first slider 105 is connected to the first slide groove 104. The fixing frame 205 is fixedly connected. The fixed connection between the first slider 105 and the fixing frame 205 can play an auxiliary role in the sliding process of the fixing frame 205, so that the fixing frame 205 slides more smoothly and improves the stability of use. The screw rod 203 is rotatably connected to the fixing seat 201, and the second slider 204 is adapted to the screw rod 203. The second slider 204 is slidably connected to the second slide groove 202. The screw rod 203 can drive the second slider 204 to move linearly inside the second slide groove 202. The slicing knife 207 is slidably connected to the third sliding groove 206, and the slicing knife 207 is extended to the right side of the fixed frame 205 and is fixedly connected with a handle 2071. Through the sliding connection between the slicing knife 207 and the third sliding groove 206, the handle 2071 can be pressed down to drive the slicing knife 207 to slide downward inside the third sliding groove 206 to complete the slicing work. The fixed frame 205 is fixedly connected to the second sliding block 204, and a positioning point 2051 is engraved near the left side of the top of the fixed frame 205.

[0033] The working process of the utility model is as follows: when a pathological specimen preparation device is used for slicing pathological specimens, the pathological specimen is first placed on the top of the base 1, and the side of the base 1 close to the L-shaped plate 103 is fitted with the front face of the L-shaped plate 103. The screw rod 203 is rotated according to the required slice thickness, so that the screw rod 203 drives the fixing frame 205 to move in the direction of the L-shaped plate 103 through the second slider 204. The fixing frame 205 is fixedly connected with the first slider 105 to assist the sliding of the fixing frame 205. During the process, the handle 2071 is lifted to drive the slicing knife 207 to move to the top of the inner side of the fixing frame 205 to prevent the knife from blocking the movement of the fixing frame 205. The positioning point 2051 points to the ruler 20 8 to determine the position of the slicing knife 207. After it is adjusted to a suitable position, stop rotating the screw rod 203 and press down the handle 2071 to drive the slicing knife 207 to slide downward under the limit of the third slide groove 206 to complete the slicing of the pathological specimen. The slice thickness can be accurately adjusted to prevent the impact on the study and judgment of the disease, and effectively improve the slicing effect. After the slicing work is completed, the slicing knife 207 is lifted upward and the screw rod 203 is rotated in the opposite direction to drive the fixing frame 205 to move a distance toward the back side of the L-shaped plate 103. Use your fingers to lightly press the pathological slice to make it close to the L-shaped plate 103, and pull out the L-shaped plate 103 to the right to take out the slice, thereby improving the convenience of use.
