[0026] The utility model will be further described below in combination with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples.

[0027] Example 1:

[0028] As Figures 1-5 ​​​As shown, the preservation device for E. coli alkaline lysis solution provided by the utility model, including: two support plates 1 arranged in alignment, two support plates 1 are fixed through four support frames 2, the interval of two support plates 1 is less than the shortest test tube length, a plurality of perforations 3 are formed on support plate 1, perforation 3 is used to pass through test tube, it is worth mentioning that the test tube in the embodiment is used for storing E. coli alkaline lysis solution, one side of perforation 3 is equipped with clamping mechanism 4, clamping mechanism 4 includes T-shaped lifting plate 5, lifting plate 5 is vertically slidably installed on one side of perforation 3, one side of lifting plate 5 is installed rack 6, one side of rack 6 is engaged and installed gear 7, gear 7 is rotatably connected with support plate 1, rubber material pressure head 8 is installed on gear 7, and elastic connecting piece is arranged between lifting plate 5 and support plate 1, two elastic connecting pieces are symmetrically arranged, when test tube is not inserted in perforation 3, pressure head 8 is located in perforation 3, and it is in the basic horizontal state, when it is necessary to insert test tube, press lifting plate 5, make rack 6 descend, and then make gear 7 rotate, gear 7 rotates, makes pressure head 8 overturn, makes pressure head 8 leave the vertical area in which perforation 3 is located, then test tube can be inserted in the perforation 3, then lifting plate 5 is released, lifting plate 5 is elevated under the action of elastic connecting piece, makes gear 7 reverse, and pressure head 8 overturns to the side close to perforation 3, until pressure head 8 tightly fixes test tube in perforation 3, the test tube fixing mode can be used for test tubes of different diameters, without any adjustment, so that the device is more convenient to use.

[0029] By setting support plate 1 and support frame 2, and setting clamping mechanism 4 including lifting plate 5, rack 6, gear 7, pressure head 8 and elastic connecting piece, different tube diameters of test tubes can be fixed in perforation 3 without any adjustment, and the use convenience of the device is improved.

[0030] Embodiment 2:

[0031] As Figures 2-4 shown, the elastic connecting piece includes guide pipe 9 fixedly installed on the side of lifting plate 5, guide pipe 9 is located below support plate 1, guide rod 10 is inserted and installed in guide pipe 9, the top end of guide rod 10 is fixedly connected with the bottom of support plate 1, limit plate 11 is installed on the bottom end of guide rod 10, spring 12 is sleeved on guide rod 10, and the spring 12 is always in compression state, when lifting plate 5 descends, guide pipe 9 slides downward along guide rod 10, and then the spring 12 is compressed, after releasing the hand, under the action of compressed spring 12, guide pipe 9 slides upward along guide rod 10, it is worth mentioning that guide pipe 9 is stopped when it is maximally elevated to contact the bottom of support plate 1.

[0032] By setting up an elastic connector including a guide tube 9, a guide rod 10, a limiting plate 11, and a spring 12, the lifting plate 5 can be raised under the action of elastic force after it is released.

[0033] Example 3:

[0034] like Figures 3-4 As shown, multiple linkage components are installed between the two support plates 1. The linkage components include a threaded sleeve 14 and two screws 13. The threads of the two screws 13 have opposite directions and are connected to both ends of the threaded sleeve 14. The ends of the two screws 13 are respectively fixedly connected to the upper and lower lifting plates 5, thereby enabling the clamping mechanisms 4 on the aligned perforations 3 to be linked. Simply pressing the upper lifting plate 5 will cause the lower lifting plate 5 to descend synchronously. Furthermore, if the threaded sleeve 14 is rotated to bring the two lifting plates 5 closer together, the lower lifting plate 5 cannot rise, causing the upper lifting plate 5 to descend. Therefore, the upper clamping head 8 will rotate clockwise, resulting in different initial angles for the two clamping heads 8. When the test tube is fixed, the clamping head 8 of the upper perforation 3 has a smaller clamping force on the test tube. Relatively speaking, this fixing method is more suitable for clamping and fixing test tubes with a bottom diameter slightly smaller than the top diameter.

When in use, the pressing plate 15 is installed on the top of the lifting plate 5 on the upper support plate 1, so that the lifting plate 5 can be pressed down. Since the pressing plate 5 has a larger area, the pressing comfort is higher.

[0038] By installing a pressing plate 15 on the top of the lifting plate 5, the comfort of using the device can be improved.

[0039] Example 5:

[0040] like Figure 5 As shown, a mounting groove 16 is provided on one side of the perforation 3. The gear 7 is connected to both sides of the mounting groove 16 through a rotating shaft. The width of the mounting groove 16 is slightly larger than the thickness of the gear 7. Insertion grooves 17 are provided on both sides of the mounting groove 16. The lifting plate 5 is inserted into the insertion groove 17 and moves up and down along the insertion groove 17.

[0041] By setting the mounting slot 16 and the plug slot 17, the installation of the gear 7 and the lifting plate 5 can be facilitated.

[0042] Working principle: when using, press the lifting plate 5 when needing to insert the test tube, make the rack 6 descend, and then make the gear 7 rotate, the gear 7 rotates, makes the pressing head 8 overturn, makes the pressing head 8 leave the vertical area where the perforation 3 is located, then the test tube can be inserted into the perforation 3, then release the lifting plate 5, the lifting plate 5 is elevated under the action of the elastic connecting piece, makes the gear 7 reverse, the pressing head 8 overturns to the side close to the perforation 3, until the pressing head 8 fixes the test tube in the perforation 3, the test tube fixing mode can be used for different diameter test tubes, without any adjustment, makes the device more convenient to use.
