The placement box 14 has arrayed test tube cavities 15 for placing test tubes, and a rubber protective sleeve 151 for protecting the test tubes is provided inside the test tube cavity 15. The rubber protective sleeve 151 fits tightly against the inside of the test tube cavity 15, forming a soft protective layer. When the test tube contacts the wall of the test tube cavity 15 during rotation or movement, the rubber protective sleeve 151 can absorb and disperse the impact. The upper surface of the placement box 14 is equipped with an auxiliary fixing component 2 for fixing the test tubes, and the other end of the rotating rod 13 is equipped with a driving component 3 for driving the rotating rod 13. Suction cups 101 are fixedly installed at the four corners of the lower surface of the base plate 1. The suction cups 101 can tightly adhere the base plate 1 to the experimental table through their adsorption, thereby achieving the effect of fixing the base plate 1. In the specific use process, the test tubes containing microbial samples are first placed into the test tube cavity 15 one by one, and the auxiliary fixing component 2 is used to fix the test tubes. The driving component 3 is started, and the rotating rod 13 will drive the placement box 14 and the test tubes inside to start rotating. The rotation helps the microbial samples to mix evenly in the test tubes and promotes the growth and reproduction of microorganisms. After the test is completed, the driving component 3 is turned off, and the placement box 14 is waited to stop rotating completely before the test tubes are taken out from the test tube cavity 15.

In actual use, the test tubes are inserted into the test tube cavities 15 one by one, and the Velcro hook face 21 and the Velcro loop face 22 are attached to each other around the test tubes to fix the test tubes.

[0021] As an embodiment in the present embodiment, as shown in Figure 1 and Figure 2 As shown, the driving assembly 3 includes a gear 31 fixedly sleeved on the outer wall of the rotating rod 13, a limiting block 32 fixedly connected on the side wall of the support plate 11, a limiting sliding groove 33 formed on the side wall of the limiting block 32 away from the support plate 11, a sliding block 34 slidingly connected in the limiting sliding groove 33, a rack 35 fixedly connected on the side wall of the sliding block 34, the rack 35 in meshing transmission with the gear 31, a connecting plate 36 fixedly connected on the side wall of the rack 35 away from the sliding block 34, a limiting frame 37 fixedly connected on the side wall of the connecting plate 36, limiting strip-shaped sliding grooves 371 formed on the opposite two side walls of the limiting frame 37, a lifting block 372 slidingly connected between the two limiting strip-shaped sliding grooves 371, a linkage rod 373 rotatably connected on the side wall of the lifting block 372, a fixed disc 374 fixedly connected on the other end of the linkage rod 373, a support table 38 fixedly connected on the upper end face of the bottom plate 1, a driving motor 39 fixedly installed on the top side wall of the support table 38, a driving shaft 391 fixedly connected on the output end of the driving motor 39, the driving shaft 391 fixedly connected at the center of the fixed disc 374. In actual use, the driving motor 39 is arranged to drive the driving shaft 391 to rotate, the driving shaft 391 drives the fixed disc 374 to rotate synchronously, the fixed disc 374 drives the linkage rod 373 to rotate, so that the linkage rod 373 drives the lifting block 372 to move up and down in the limiting frame 37. During the up and down movement of the lifting block 372, the limiting frame 37 drives the rack 35 to move horizontally through the connecting plate 36. In this way, the rack 35 drives the gear 31 to rotate, and the gear 31 drives the placement box 14 and the test tubes thereon on the rotating rod 13 to start rotating (to reciprocating rotate left and right at a large amplitude), so as to uniformly mix the microbial samples in the test tubes.
