[0043] In some embodiments of the present invention, the sieve plate 1, the positioning plate 2, the transition plate 3 and the cavity plate 4 all have a tetrahedral structure, the first limiting column 22 is arranged at the four top corners of the positioning plate 2, and the first limiting hole 6 is arranged opposite to the first limiting column 22.

[0044] Specifically, the positioning plate 2 is provided with a plurality of first limiting posts 22, and the sieve plate 1, transition plate 3, and cavity plate 4 are provided with first limiting holes 6. When the positioning plate 2 is assembled with the sieve plate 1 and the mounting plate assembly, the limiting posts are inserted into the limiting holes, thereby further ensuring the alignment of the sieve hole 11, the positioning pin 21, the transition hole 31, and the mounting hole 41, effectively avoiding installation deviation caused by component misalignment.

[0051] Specifically, the positioning pin 21 has a receiving surface 511. When the sieve plate 1 is buckled with the positioning plate 2, the petal portion 52 of the copper shell 5 faces the positioning plate 2, so that the petal portion 52 abuts against the receiving surface 511. The end of the positioning pin 21 away from the positioning plate 2 has a conical structure, thereby forming a guiding slope to ensure that the copper shell 5 can be accurately mounted on the positioning pin 21.
