Referring to fig. 9, in one embodiment, a side of the second grinding tool 320 away from the output shaft 210 is recessed in a direction away from gravity, and a side of the second grinding tool 320 close to the output shaft 210 is raised in the direction of gravity. The second grinding burr 320 contacts the sample in the sample cup before the first grinding burr 310. It will be appreciated that the linear velocity of the end of the grinding blade remote from the output shaft 210 is greater and therefore the surface of the portion is faster relative to the rotational velocity of the sample, and that by recessing the side of the second grinding blade 320 remote from the output shaft 210 in a direction away from gravity, the recessed portion can be made to have a gap from the sample level. Since the rotation speed of the side is fast relative to the sample, an air film is formed on the portion of the second grinding blade 320 and the liquid surface of the sample, the surface of the second grinding blade 320 can be protected by the air film, the service life of the second grinding blade 320 is prolonged, and the grinding effect is not affected. On the side of the second grinding blade 320 close to the output shaft 210, the rotation angle speed of the second grinding blade 320 is slow, so that the grinding effect is not good, and the side of the second grinding blade 320 close to the output shaft 210 is convex in the direction of gravity, so that the contact area between the second grinding blade 320 and the sample can be increased, and the grinding effect can be improved.

In one embodiment, a side of the first grinding burr 310 near the output shaft 210 is recessed in a direction away from gravity, and a side of the first grinding burr 310 away from the output shaft 210 is raised in the direction of gravity. It can be understood that the sample ground by the first grinding knife contacts the first grinding knife 310, and the movement speed of the sample around the sample cup ground by the first grinding knife 310 is slow, so that the contact area with the sample can be increased by the protrusion of the first grinding knife 310 away from the output shaft 210 in the direction of gravity, and the grinding effect is improved. On the side of the first grinding blade 310 close to the output shaft 210, since the second grinding blade 320 has a large contact area when grinding the portion, and basically no air film exists, the sample speed of the portion ground by the second grinding blade 320 is high, and by making the side of the first grinding blade 310 close to the output shaft 210 concave in the direction away from gravity, the air film can be generated at the portion where the portion of the sample contacts the first grinding blade 310, and the inner side of the first grinding blade 310 is protected from being damaged by direct contact friction.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present patent. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
