[0031] Referring to Figures 1-6 As shown, the cleaning device 2 includes a rotating part 21. The rotating part 21 is rotatably connected to the opening of the test tube body 1. A cover plate 22 is provided on one side of the test tube body 1. The cover plate 22 is threadedly adapted to the inside of the rotating part 21. A limiting ring 29 is fixedly connected to the arc surface of the rotating part 21 inside the test tube body 1. A limiting groove is opened in the test tube body 1 corresponding to the limiting ring 29. The limiting ring 29 is slidably adapted to the limiting groove. A cleaning plate 23 is fixedly connected to one side of the rotating part 21 inside the test tube body 1. One end of the cleaning plate 23 is fixedly connected to an arc plate 24. The cleaning plate 23 and the arc plate 24 are mutually attached to the inside of the test tube body 1. When the test tube body 1 needs to be used, the staff places the food into the test tube body 1. Then the staff moves the cover plate 22 to the opening of the test tube body 1. The cover plate 22 is aligned with the rotating part 21, and the cover plate 22 and the rotating part 21 are fixed through the threads on the rotating part 21 and the cover plate 22. When the test tube body 1 needs to be cleaned, the staff opens the cover plate 22 and sends clear water into the inside of the test tube body 1. At this time, the staff moves the rotating part 21, and the limiting ring 29 on the rotating part 21 moves in the limiting groove of the test tube body 1, achieving the effect of restricting the moving direction of the rotating part 21. And the cleaning plate 23 and the arc plate 24 at one end of the rotating part 21 move inside the test tube body 1, achieving the effect of cleaning the inner wall of the test tube body 1. Finally, the staff pours out the cleaning water. By the cleaning plate 23 and the arc plate 24 provided in the cleaning device 2 being attached to and rotating with the inner wall of the test tube body 1, the effect of cleaning the inner wall of the test tube body 1 is achieved, avoiding the residues tested in the test tube body 1 last time from sticking to the inner wall of the test tube body 1.
[0032] Reference Figures 1-6 As shown, the arc surface of the rotating member 21 is fixedly connected with a plurality of anti-sliding blocks 25, and the plurality of anti-sliding blocks 25 are distributed in a circle. By providing the anti-sliding blocks 25, the friction between the staff's hand and the rotating member 21 is increased, thereby facilitating the staff to rotate the rotating member 21. The arc surface of the test tube body 1 is sleeved with a sealing ring 26, and the sealing ring 26 is located at the connection between the rotating member 21 and the test tube body 1. By providing the sealing ring 26, the effect of sealing the gap between the rotating member 21 and the test tube body 1 is achieved, thereby preventing the items in the test tube body 1 from flowing out of the gap. The upper surface of the cover plate 22 is rotatably connected with a rotating plate 27, and a pull rope 28 is fixedly connected to one side of the rotating plate 27, and one end of the pull rope 28 is fixedly connected to the test tube body 1.

[0036] When it is necessary to install the protective plates 31, the staff moves the two protective plates 31 to the two sides of the test tube body 1 respectively, and aligns the slots 39 on the two protective plates 31 with the slots 39 on the test tube body 1. At this time, the positioning rod 32 on one of the protective plates 31 is inserted into the positioning slot 33 of the other protective plate 31 with the help of the pointed protrusion 36, and the rubber ring 34 on the positioning rod 32 is squeezed and deformed by the positioning slot 33. When the rubber ring 34 moves to the position of the fixing slot 35, the rubber ring 34 returns to its original state under the action of its own restoring elastic force and enters the fixing slot 35, thereby achieving the effect of fixing the two protective plates 31. The protective plates 31 set by the protective device 3 achieve the effect of protecting the test tube body 1, and avoid the test tube body 1 from falling off the test tube rack and breaking as much as possible.
