It can also avoid the temperature rise of the cutter, reduce the cutter wear, improve the service life of the cutter, and reduce the influence of cutter wear particles on detection accuracy.

[0031] Specifically, in order to facilitate the taking of the pressing plate 7, the upper end of the pressing plate 7 is fixedly connected with a pressing rod 8; the center of the barrel cover 3 is provided with a hole for the pressing rod 8 to penetrate.

[0032] Specifically, in order to further improve the crushing effect, the inner wall of the barrel body 2 is provided with a plurality of convex columns 6 protruding inward; the pressing plate 7 is provided with a plurality of grooves matched with the convex columns 6. The convex columns 6 can limit the rotation of the sample to a certain extent.

[0033] Specifically, the cross section of the convex column 6 is triangular. The sharp corners of the triangle are provided with transition fillets. It can also be adjusted to be arc-shaped, rectangular or trapezoidal according to requirements.

[0034] Specifically, in order to avoid the influence of metal cutter wear on the detection accuracy of heavy metals in the sample, the cutter 5 is a full ceramic cutter or a ceramic coating is arranged on the surface of the metal cutter.

[0035] Specifically, in order to improve the crushing effect, the cutter 5 includes first blades 501 and second blades 502 arranged alternately; the first blades 501 are bent upward, and the second blades 502 are bent downward.
