[0096] The pestle rod 222 includes a rectangular cross plate 2221 and a vertical rod 2222 connected to the cross plate 2221. The vertical rod 2222 is a cylinder, and a T-shaped structure is formed between the cross plate 2221 and the vertical rod 2222. The side of the cross plate 2221 away from the vertical rod 2222 is in contact with the upper cam 462, and the side of the vertical rod 2222 away from the cross plate 2221 is fixedly connected to the pestle head 221.

The fixed ring 3222 can be fixed on the support plate 321 through the fixed block 3221 and move on the support plate 321.

[0107] In an alternative embodiment, continue to refer to Figure 2 、 Figure 6 and Figure 7 As shown, a support plate convex groove 3211 matching the I-shaped structure is provided on one side of the support plate 321 away from the rear body 12 of the machine case. The middle cross-section of the support plate convex groove 3211 perpendicular to its length direction is convex-shaped. The support plate convex groove 3211 extends along the length direction of the support plate 321, and the I-shaped structure is slidably connected in the support plate convex groove 3211.

[0108] Specifically, the support plate 321 and the support ring 322 are slidably connected; a support plate convex groove 3211 extending along the length direction of the support plate 321 is provided on one side of the support plate 321 away from the rear body 12 of the machine case.

[0109] The fixing block 3221 is of an I-shaped structure. The rack plate 321 and the fixing ring 3222 are respectively arranged on the opposite sides of the fixing block 3221, and the fixing block 3221 slides in the rack plate groove 3211 of the rack plate 321. The fixing block 3221 includes a connecting portion and a first rectangular portion and a second rectangular portion vertically connected to both ends of the connecting portion. The first rectangular portion, the connecting portion and the second rectangular portion form an I-shaped structure. Both the first rectangular portion and the second rectangular portion are rectangular blocks. The first rectangular portion on the fixing block 3221 is arranged in the rack plate groove 3211. One side of the second rectangular portion on the fixing block 3221 away from the first rectangular portion is welded to the fixing ring 3222. The middle parts of the first rectangular portion and the second connecting portion on the fixing block 3221 are respectively connected to both ends of the connecting portion along the extending direction of its length. The connecting portion can be a rectangular block or a cylinder.
