[0032] As shown in Figure 1 - Figure 3 Limiting assembly 3; limiting assembly 3 includes rotating shaft 31 fixedly connected on centrifuge body 1, rotating shaft 31 is rotatably connected with positioning plate 32 at the top end, positioning plate 32 is movably connected with support rod 33 in the inside, support rod 33 is fixedly connected with clamping block one 34 at the bottom end, support rod 33 is fixedly connected with clamping block two 35 on the outside, the bottom end of slide plate 22 is fixedly connected with positioning block 36, the bottom end of clamping block two 35 is in contact with the bottom end of positioning block 36, the top end of clamping block one 34 is in contact with the bottom end of positioning block 36, the bottom end of clamping block one 34 is in contact with the top end of slide plate 22;

[0033] The rotating shaft 31 is used to support the positioning plate 32 and provides a rotatable support point for the positioning plate 32, the positioning plate 32 is used to determine the accurate position of the supporting rod 33, so as to ensure that the limiting assembly 3 can work with the sliding plate 22 correctly, the existence of the supporting rod 33 provides a convenient operation point for the operator, so that the operation of the whole limiting assembly 3 is more convenient, the clamping block one 34 and the clamping block two 35 jointly limit the lateral movement of the sliding plate 22, so as to ensure that the sliding plate 22 will not exceed the predetermined track, thereby preventing the sliding plate 22 from moving out of its proper working path, the positioning block 36 further determines the position of the sliding plate 22 by contacting the clamping block one 34 and the clamping block two 35, so as to ensure the stability of the sliding plate 22 during movement, so that the operation of the whole mechanical system is more stable.

[0038] In use: the slide plate 22 is smoothly moved along the path of the guide rail 21 to the top position of the centrifuge body 1. When the slide plate 22 slides to the end of the guide rail 21, the positioning is realized by rotating the positioning plate 32. The positioning plate 32 is connected with the centrifuge body 1 through the rotating shaft 31 and can be flexibly rotated. Then, the slide plate 22 is lifted up by the supporting rod 33, so that the spring 42 is stretched. During the lifting process of the supporting rod 33, the clamping block one 34 is ensured to be aligned with the clamping groove position on the positioning block 36. Once the supporting rod 33 is released, the pressure of the spring 42 is released, so that the clamping block one 34 is firmly clamped on the positioning block 36. In this way, the clamping block two 35 is also clamped on the top end of the positioning block 36, finally realizing the stable fixation of the slide plate 22 on the centrifuge body 1 through the positioning block 36. When it is needed to open the slide plate 22, the bottom end of the slide plate 22 is slid along the collecting groove 23. During the contact of the slide plate 22 with the collecting groove 23, the impurities on the bottom of the slide plate 22 are scraped off and concentrated on the cleaning plate 24, so as to facilitate the subsequent cleaning work.
