The base 5 is connected to the column 1, and the adjusting rod 3 is arranged on the column 1 through the first adjusting knob 2, and the adjusting rod 3 can be adjusted up and down. The rotatable clamp 4 is connected to the adjusting rod 3 through the rotating shaft 4-3, and the rotatable clamp 4 is adjusted in tightness through the second adjusting knob 4-2, and the anti-slip rubber sheet 4-1 is fixed in the rotatable clamp 4. The base 5 has a rubber ring fixing groove 5-1, and the rubber ring fixing groove 5-1 is used to fix the tightened frost-resistant rubber ring 6, and the standard sample is placed between the frost-resistant rubber rings 6 to fix it.

[0022] In this embodiment, the adjusting rod can be adjusted up and down by the first adjusting knob. When the temperature is lowered, the probe is inserted into the rotatable clamp, and the height of the adjusting rod can be adjusted by the first adjusting knob on the column to control the optimal monitoring height of the probe in the cryopreservation tube.

[0023] The overall operation steps are simple, which reduces the frequency of operators manually changing different probe fixing methods and different standard sample fixing methods, avoiding the temperature rising too fast and affecting the cell cooling effect. It also avoids the risk of occupational exposure caused by long operation time.

[0024] Example 2

[0025] On the basis of Example 1, the rotatable clamp and the rotating shaft are welded into one body.

[0026] In this embodiment, the tightness of the rotatable clamp is adjusted by the second adjustment knob on the clamp. When the rotating shaft is rotated upward to vertical, the rotatable clamp is prevented from exceeding the rubber ring by moving the adjustment rod; when the rotating shaft is rotated downward to horizontal, the rotatable clamp can be controlled to exceed the rubber ring by 1-2 cm.

[0027] Example 3

[0028] Based on Example 2, the frost-resistant rubber ring is a silicone rubber ring.

[0029] In this embodiment, the frost-resistant rubber ring has the characteristics of low temperature resistance, good elasticity, etc. The frost-resistant rubber ring is placed in the rubber ring fixing groove of the base, and can be suitable for a special silicone ring of 12-13 cm.

[0030] Example 4

[0031] Based on the third embodiment, anti-slip patterns are provided on the anti-slip rubber sheet.

[0032] In this embodiment, the anti-slip rubber sheet is provided with anti-slip grooves, which can increase the friction force and improve the anti-interference ability of the probe during the cooling process.

[0033] Example 5

[0034] On the basis of Example 4, the base, the column, the adjusting rod, the first adjusting knob, the second adjusting knob, the rotatable clamp, and the rotating shaft are all made of stainless steel.

[0035] In this embodiment, stainless steel material is used, which has strong rigidity and can prevent rust from condensed water. Under the same conditions, it is more conducive to long-term use.

[0036] Example 6

[0037] Based on Example 5, the standard sample is placed under the twist clamp.

[0038] In this embodiment, the probe can be fixed on a rotatable clamp, and a corresponding placement position can be flexibly selected according to the cell carrier.

[0039] Example 7

[0040] Based on Example 6, the overall size of the fixing device is a cube of approximately 14*9*20 cm.

[0041] In this embodiment, the overall size of the fixing device is a cube of about 14*9*20 cm, which meets the inner cavity space size of most medium-sized and large-sized programmed cooling instruments or deep low temperature storage boxes on the market and has high compatibility.

[0042] Example 8

[0043] Based on Example 7, the column is a solid steel column and the adjustment rod is a hollow steel column.

[0044] In this embodiment, the column is a solid steel column and the adjustment rod is a hollow steel column. The reason is that the column can rely on its own weight to stabilize the base without any connecting parts. At the same time, the adjustment rod uses a hollow steel column to further improve the overall stability and facilitate up and down adjustment.

[0045] Example 9

[0046] Based on Example 8, the size of the column is larger than the hole size of the base, and is connected to the hole of the base.

[0047] In this embodiment, the base has a height of 3 cm, and the diameter of the column is slightly larger than the diameter of the hole of the base, so that the column can be firmly fixed on the base without connecting parts, which is convenient for separation and later replacement of consumables such as freeze-resistant rubber rings and anti-slip films.

[0048] Example 10

[0049] Based on Example 9, the base can be used to place standard samples of different specifications.

[0050] In this embodiment, the opening length of the U-shaped base is about 7 cm, which can accommodate but is not limited to accommodating cryotubes of different specifications such as 1.8 ml, 4.5 ml, and even cryobottles.

[0051] From the above description, it can be seen that the beneficial effects of the utility model are: providing a multifunctional cell cryopreservation temperature probe fixing device with a reasonable structure, safety and reliability, which can use a temperature probe to measure and monitor the temperature changes of different cell carriers without repeated calibration. It eliminates the risk of the probe hitting the wall or bottoming out in the cell carrier due to the inability to fix the probe, and improves the accuracy of operation.
