[0043] A protective shell 11 is provided above the cleaning sleeve 9, and a limiting plate 12 is fixed in the protective shell 11, and a plurality of test tubes 13 for laboratory use are movably connected in the limiting plate 12. The test tubes 13 are placed in the protective shell 11 with their openings facing downward, so that the sewage after cleaning can be quickly discharged from the test tubes 13. At the same time, a plurality of drainage pipes 3 corresponding to the positions of the test tubes 13 are provided at the bottom of the protective shell 11, and the diameter of the drainage pipes 3 is smaller than the inner diameter of the test tubes 13, so as to prevent the test tubes 13 from falling from the protective shell 11. A protective cover 14 is movably connected to the surface of the protective shell 11. Two limit rods 10 for limiting the position of the protective shell 11 and the protective cover 14 are fixed to the inner walls on both sides of the cleaning box 1, which can prevent the protective shell 11 from moving up and down when the test tube 13 is cleaned, thereby ensuring the cleanliness of the test tube 13. A plurality of fixing sleeves 15 for fixing the test tube 13 are fixed to the bottom of the protective cover 14. The fixing sleeves 15 can be made of rubber material. At the same time, the fixing sleeves 15 match the size of the test tube 13. After the test tube 13 is inserted into the fixing sleeve 15, the test tube 13 will not fall from the fixing sleeve 15 during the inversion process of the test tube 13.

[0044] The outer walls of the front and rear sides of the protective shell 11 are fixed with positioning blocks 16 by screws, and the surface of the protective cover 14 is fixed with a positioning box 17, and a rotating column 18 is rotatably connected in the positioning box 17. A gear 19 is fixed to the outer wall of the rotating column 18, and two racks 20 meshing with the gear 19 are movably connected in the positioning box 17.

The opposite surfaces of the two positioning blocks 16 are provided with positioning grooves matching the positioning pin 22, and the outer walls of the front and rear sides of the moving block 21 are fixed with a positioning pin 22. The walls are provided with a rotation groove, and a ball 211 is rotatably connected in the rotation groove of the moving block 21. The inner walls on the front and rear sides of the positioning box 17 are provided with a slide groove 171 for the ball 211 to slide, which can make the moving block 21 move more smoothly in the positioning box 17. Rotating the rotating column 18 can drive the positioning pin 22 to move. When the positioning pin 22 is inserted into the positioning block 16, the protective shell 11 can be stably connected with the protective cover 14 to avoid accidental separation of the protective cover 14 or the protective shell 11. The outside of the rotating column 18 is provided with a fixing ring 23 fixedly connected to the positioning box 17. The rotating column 18 is movably connected to the fixing ring 23. A threaded hole is provided on the fixing ring 23, and a fixing bolt 24 is threadedly connected to the threaded hole of the fixing ring 23. Tightening the fixing bolt 24 can fix the position of the rotating column 18 to prevent the rotating column 18 from rotating accidentally. The outer walls of the front and rear sides of the protective shell 11 are fixed with handles 26 by bolts. A sealing door 25 is installed on the cleaning box 1. The two handles 26 are respectively fitted with the sealing door 25 and the back plate of the cleaning box 1, so that after the sealing door 25 is closed, the protective shell 11 can be prevented from moving forward and backward in the cleaning box 1. The cleaning sleeve 9 can be moved to ensure that it can accurately enter the test tube 13 and comprehensively clean the test tube 13. At the same time, the setting of the handle 26 also facilitates the removal of the protective shell 11 from the cleaning box 1. By placing the glass test tube 13 to be cleaned in the protective shell 11 and cooperating with the protective cover 14, foreign objects can be prevented from directly hitting the test tube 13 during the process of taking and placing the glass test tube 13, thereby effectively protecting the test tube 13. The electric telescopic rod 4 can drive the cleaning sleeve 9 to move up and down, thereby automatically and comprehensively cleaning the inner wall of the test tube 13.
