Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar modules or modules having the same or similar functionality throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.

Example one

Fig. 1 is a schematic view of an anti-rolling device according to an embodiment of the present invention, and fig. 2 is a schematic view of an area a in fig. 1. With reference to fig. 1 and 2, the anti-rolling device 1 is an integrated structure, and includes a first reference surface 2 and a second reference surface 3, where the first reference surface 2 and the second reference surface 3 are disposed on the same side of the anti-rolling device 1; the second reference surface 3 is arranged on the first arm 4 of the anti-roll device 1; the first reference surface 2 is arranged on the second arm 5 and the third arm 6 of the anti-roll device 1; wherein the second arm 5, the first arm 4 and the third arm 6 are connected in sequence, and a height difference D exists between the first reference surface 2 and the second reference surface 3. When slicing, the first reference surface 2 is brought into contact with the cutting blade, and the sliced sheet passes through the gap formed by the second reference surface 3 and the cutting blade and is set.

Preferably, the anti-roll device 1 is a closed frame. The area surrounded by the second arm 5, the first arm 4 and the third arm 6 is hollow. When slicing is performed, the user can observe the curling of the sheet from the region and can adjust the position of the anti-curl device 1 finely at appropriate time. The length of the first arm 4 in the sheet passing direction may be determined according to practical circumstances and is not limited herein. The closed frame is made of metal, and plays a role in preventing static electricity.

Example two

As another embodiment of the present invention, fig. 3 is a schematic view of an anti-rolling device provided by the second embodiment of the present invention, and fig. 4 is a schematic view of a B region in fig. 3. With reference to fig. 3 and 4, the difference from the first embodiment is that the anti-rolling device 1 is a flat plate. When slicing, the first reference surface 2 is brought into contact with the cutting blade, and the sliced sheet passes through the gap formed by the second reference surface 3 and the cutting blade and is set.

Since the anti-curl device 1 is a flat plate, the length of the gap formed by the second reference surface 3 and the cutting blade in the sheet passing direction is long. During the slicing process, the entire slice will be in the gap. In order to facilitate the observation of the curling condition of the sheet during the slicing process by the user, the position of the anti-rolling device 1 is finely adjusted in time, and preferably, the flat plate is made of a transparent material, such as glass.

In the embodiment of the present invention, the first reference surface 2 needs to be in close contact with the cutting blade, and in order to reduce the requirement for processing, the first reference surface 2 is provided in the local region of the second arm 5 close to the first arm 4, and the first reference surface 2 is provided in the local region of the third arm 6 close to the first arm 4.

EXAMPLE III

Fig. 5 is a schematic view of the anti-roll device provided by the third embodiment of the present invention being placed on the knife rest, and fig. 6 is a schematic view of the region C in fig. 5. The slicer comprises an anti-rolling device 1 and a knife rest 9, wherein a cutting knife 10 is clamped on the knife rest 9. The first reference surface 2 is brought into contact with the cutting edge, and when slicing, the tissue sample falls over the cutting edge and is sliced, and then the slice enters the gap formed by the second reference surface 3 and the cutting edge, which gap is used to accommodate the sliced slice. The direction indicated by the arrow X in fig. 6 is the direction in which the sheet passes.

In the embodiment of the present invention, the anti-rolling device 1 further includes a connecting rod 7 and a locking member 8.
