[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 5As shown, an embodiment of the utility model provides a torque connector, which includes a rotating rod 10, a spring 20 and an opening cover structure 121. The rotating rod 10 includes a first rod body 11 and a second rod body 12 that are rotatably connected. The first end of the first rod body 11 can be connected to a driving part, the first end of the spring 20 is sleeved on the second end of the first rod body 11, and the second end of the spring 20 is sleeved on the first end of the second rod body 12. The first rod body 11 and the second rod body 12 are both interference fit with the spring 20, and the opening cover structure 121 is arranged at the second end of the second rod body 12.

[0029] The torque connector provided by the present embodiment is applied, and the torque connector includes a rotating rod 10 and a spring 20. The rotating rod 10 includes a first rod body 11 and a second rod body 12. The first end of the first rod body 11 is connected to the driving part so that the driving part can drive the first rod body 11 to rotate. The first end of the spring 20 is sleeved on the second end of the first rod body 11, and the second end of the spring 20 is sleeved on the first end of the second rod body 12. The first rod body 11 and the second rod body 12 are both interference fit with the spring 20. When the driving part drives the first rod body 11 to rotate, the first rod body 11 and the second rod body 12 are connected by the spring 20, so that when the driving part drives the first rod body 11 to rotate along the first direction to open the cryopreservation tube, the first rod body 11 and the second rod body 12 are tightly connected by the spring 20, and then the opening operation is realized by using the opening structure 121 at the second end of the second rod body 12. When the driving unit drives the first rod 11 to rotate along the second direction, the spring 20 expands under the force of the driving unit, so that the friction between the first rod 11 and the spring 20 and the friction between the second rod 12 and the spring 20 are small, thereby enabling relative rotation between the first rod 11 and the second rod 12, thereby avoiding the problem of large torque during the cover closing operation, which may cause easy damage to the connection between the tube body and the tube cap, and facilitating the use of the torque connector to open and close the cryopreservation tube.

[0030] It should be noted that the first direction refers to the direction of opening the cover of the cryogenic tube, and the second direction refers to the direction of closing the cover of the cryogenic tube.

[0031] Among them, the spring 20 has a contracted state in which the rotating rod 10 rotates along the first direction and an expanded state in which the rotating rod 10 rotates along the second direction. When the spring 20 is in the contracted state, the first rod body 11 and the second rod body 12 are connected by the spring 20. When the spring is in the expanded state, the first rod body 11 and the second rod body 12 are separated.

[0032] like Figures 1 to 3As shown, a limiting boss 122 is provided on the outer wall of the second rod body 12, and the second end of the spring 20 abuts against the limiting boss 122. With the above structure, by providing the limiting boss 122 on the outer wall of the second rod body 12, the second end of the spring 20 abuts against the limiting boss 122, so that the spring 20 and the second rod body 12 are easily interference-fitted. The first end of the spring 20 is connected to the first rod body 11, so that the spring 20 is connected to the first rod body 11 and abuts against the limiting boss 122 on the second rod body 12. When the first rod body 11 rotates along the first direction, the friction between the second rod body 12 and the spring 20 is relatively large, and the first rod body 11 and the second rod body 12 can rotate together under the action of the spring 20 to achieve the cover opening operation. When the first rod 11 rotates along the second direction, the friction between the second rod 12 and the spring 20 is reduced, so that the friction between the second rod 12 and the spring 20 is smaller than the force of closing the cap of the cryogenic tube, so that the first rod 11 and the second rod 12 can rotate relative to each other, avoiding damage to the cryogenic tube due to excessive torque.

[0033] As 1 and Figure 2 As shown, a positioning structure is provided between the second end of the first rod body 11 and the first end of the second rod body 12, and the positioning structure includes a positioning column and a positioning hole 123. The positioning column is provided on one of the second end of the first rod body 11 and the second rod body 12, and the positioning hole 123 is provided on the other of the second end of the first rod body 11 and the second rod body 12, and the positioning column is inserted into the positioning hole 123. By providing the positioning column on one of the second end of the first rod body 11 and the second rod body 12, and providing the positioning hole 123 on the second end of the first rod body 11 and the other of the second rod body 12, when the first rod body 11 and the second rod body 12 are positioned and matched, the positioning column is used to extend into the positioning hole, so that the first rod body 11 and the second rod body 12 can be easily assembled.

[0034] It should be noted that, in this embodiment, a positioning column is provided on the first rod body 11 , and a positioning hole 123 is provided at the first end of the second rod body 12 . The positioning column can extend into the positioning hole 123 , so as to facilitate positioning and installation between the first rod body 11 and the second rod body 12 .

[0036] like Figures 2 to 4As shown, the clamping structure 30 includes a clamping block 31 and a clamping groove 32. The clamping block 31 is arranged on one of the second end of the second rod body 12 and the cover opening head 1211, and the clamping groove 32 is arranged on the second end of the second rod body 12 and the other of the cover opening head 1211.
