[0002] Shakers are mainly used in universities, medical institutions, petrochemical companies, health and epidemic prevention departments, environmental monitoring and other research departments for the shaking culture of various liquid and solid compounds such as biological, biochemical, cell and bacterial strains. At present, the shaker body and the clamps used to fix the test tubes are mostly an integral structure that cannot be separated. When using this integral connection of the clamp and the shaker body, there are the following problems: (1) The clamps cannot be replaced, making it difficult to adapt to the shaking needs of test tubes of different diameters; (2) When using the shaker, the test tubes can only be shaken on the clamps for one batch, and then removed one by one, and then new test tubes are installed one by one for the next batch of shaking. It is not possible to quickly replace a batch of test tubes by installing a batch of test tubes on spare clamps in advance and by quickly replacing the clamps, resulting in low experimental efficiency. Utility Model Content

[0031] The support block 4 has a first slot 402 with an upper opening at its center. The first slot 402 and the second slot 501 have the same diameter and are vertically corresponding. The support block 4 also has a first movable groove 401 that surrounds the first slot 402. The inner side of the first movable groove 401 is connected to the first slot 402. The first movable groove 401 and the keyway 502 are vertically corresponding.

[0032] The first insert rod 6 is inserted into both the second slot 501 and the first slot 402. The top of the first insert rod 6 protrudes from the upper surface of the snap-fit ​​connector 5. A key block 7 is fixed on the side wall at the lower end of the first insert rod 6. The key block 7 can pass downward from the key groove 502 into the first movable groove 401 and move in a circular motion around the central axis of the first insert rod 6 in the first movable groove 401. When the key block 7 moves in a circular motion in the first movable groove 401, it can be misaligned with the key groove 502.

[0033] To prevent the first insert 6 and key block 7 from shaking in the first movable groove 401 and the first slot 402 during oscillation, thus avoiding excessive noise, such as... Figure 2 and Figure 3 As shown, a first fixing plate 8 is fixedly provided at the upper end of the first insertion rod 6. The first fixing plate 8 is a circular plate structure. The diameter of the first fixing plate 8 is greater than the sum of the inner diameter of the second slot 501 and the radial length of the keyway 502 along the snap-fit ​​connector 5. The first fixing plate 8 has multiple internal threaded holes that are open from top to bottom and are equidistantly arranged around the second slot 501. A fastening screw 9 is inserted into the internal threaded hole and threadedly connected to it. The lower end of the fastening screw 9 abuts against the top of the snap-fit ​​connector 5 to fix the key block 7 in the position of the first movable groove 401.

[0034] To facilitate lifting the first insertion rod 6 and the key block 7, a handle 10 is fixedly provided on the top of the first fixing plate 8.

[0035] To prevent test tube 11 from moving upwards during shaking, such as Figure 4 As shown, a test tube rim 1101 is fixedly provided around the upper end of the test tube 11; a rotating shaft 12 located outside the test tube groove 503 is fixedly provided on the snap connector 5; a first baffle 13 is rotatably sleeved on the rotating shaft 12; a second fixing plate 14 is fixedly provided on the top of the rotating shaft 12 to prevent the first baffle 13 from falling out; when the first baffle 13 rotates around the rotating shaft 12, it can rotate to be directly above the test tube rim 1101 or outside the test tube rim 1101.

[0036] To prevent liquid from leaking out of test tube 11 and contaminating the shaker in case of accidental breakage, such as... Figure 1 , Figure 5 and Figure 6 As shown, a ring-shaped liquid storage tank 15 is fixedly mounted on the vibration platform 2. A ring-shaped third fixing plate 16 is fixedly mounted on the inner side of the liquid storage tank 15, and the third fixing plate 16 is fixedly connected to the vibration platform 2 by bolts. The liquid storage tank 15 is arranged around the support block 4, and the liquid storage tank 15 has an annular liquid storage groove with an upper opening and is coaxial with it. The liquid storage tank 15 is located directly below the test tube 11.

[0037] A permeable drain port 1501 is provided on the outer wall of the annular liquid storage tank, and a removable plug 17 is provided at the drain port 1501. In this embodiment, the plug 17 is a rubber stopper.

[0038] To facilitate the flow of liquid out of the annular storage tank, the bottom of the annular storage tank is a conical surface structure that slopes from high to low along the radial direction from the center to the outside.

[0039] Working principle: When in use, multiple matching clamps 5 are selected according to the different diameters of the test tube 11, and the height of the support block 4 is adjusted by the lifting frame 3 according to the different lengths of the test tube 11.

[0040] Install the test tube 11 that needs to be shaken in the test tube slot 503 of the first clamp 5, and rotate the first baffle 13 so that the first baffle 13 is directly above the test tube edge 1101 to prevent the test tube 11 from moving upward during shaking.

[0041] Then, place the first clamping connector 5 with the test tube 11 installed on the support 4, insert the first insert rod 6 into the second slot 501 and the first slot 402, and the key block 7, along with the first insert rod 6, passes downward from the key groove 502 into the first movable slot 401. Rotate the first insert rod 6 to make the key block 7 rotate around the central axis of the first insert rod 6 in the first movable slot 401, so that the key block 7 and the key groove 502 are misaligned. Then, rotate the fastening screw 9 so that the lower end of the fastening screw 9 abuts against the top of the clamping connector 5, and pull the key block 7 and the first insert rod 6 upward so that the top of the key block 7 abuts against the top of the first movable slot 401 to fix the position of the key block 7 in the first movable slot 401. Oscillation can then begin, and the remaining test tubes 11 can be installed on the spare clamping connectors 5.

[0042] Once the vibration of this batch of test tubes 11 is complete, the vibration of the next batch of test tubes 11 can be quickly started by removing the clamp connector 5 and replacing it with a spare clamp connector 5 that has been installed on the test tubes 11.
