The placement area 15 and the mold hole 8 provide a neat and orderly storage space for the centrifuge tube. A recessed platform 9 is provided at the upper end of the mold hole 8. The front end of the rotating shaft 4 passes through the front fixed bracket 3 and is fixedly connected to a hand crank 5 by bolts. The front lower end of the hand crank 5 is rotatably connected to a driving rocker 6. The combination of the hand crank 5 and the driving rocker 6 allows the user to easily rotate the placement roller 7. A contact spring 10 is fixedly connected to the right side between the two fixed brackets 3. The contact spring 10 provides a certain elastic force for the centrifuge tube cover to ensure that the centrifuge tube cover is firmly fixed inside the centrifuge tube.
[0030] Please refer to Figure 2 As shown, an inclined pre-cover plate 11 is fixedly connected above the contact spring piece 10, and the angle between the pre-cover plate 11 and the contact spring piece 10 is one hundred and twenty degrees to one hundred and fifty degrees. The inclined design of the pre-cover plate 11 can guide the centrifuge tube cover, making it convenient for the subsequent contact spring piece 10 to press the centrifuge tube cover.
[0031] Please refer to Figure 2 As shown, a blocking bar 12 is fixedly connected between the middle of the upper surface of the bottom plate 1 and the two fixed brackets 3. The setting of the blocking bar 12 facilitates the centrifuge tube to roll or slide on the bottom plate 1, ensuring that the centrifuge tube will not hinder the rotation of the placement roller 7.
[0032] Please refer to Figure 2 As shown, the four corners of the bottom of the base plate 1 are fixedly connected with mounting feet 13 by screws, and the bottom of the mounting feet 13 is fixedly connected with an anti-skid pad 14.

[0039] Working principle: When in use, the device is placed on the desktop by installing the base 13, and then the left hand places the centrifuge tube opening toward the side of the non-contact spring sheet 10 in the mold hole 8, and then the right hand holds the driving rocker 6 to drive the hand crank handle 5 to rotate clockwise, and the hand crank handle 5 will drive the placement roller 7 to rotate through the rotating shaft 4. When the cover of the centrifuge tube moves to the pre-cover plate 11, the cover is pre-tightened first, and the placement roller 7 rotates. The contact spring sheet 10 will contact the cover, thereby pressing the cover of the centrifuge tube. After being pressed, the centrifuge tube moves to the bottom as the placement roller 7 continues to rotate, and will automatically detach from the inside of the mold hole 8 under the action of gravity, and fall to the outside of the bottom plate 1 through the blocking bar 12.
[0040] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
