[0022] See also Figure 1-3The utility model provides a pair of tweezers for clamping cell cryopreservation tubes, comprising two groups of clamping arms 1 connected to each other at their tail ends, wherein the bottom surfaces of the tail ends of the two groups of clamping arms 1 are provided with arc-shaped grooves, which can be placed at the base of the thumb when in use, thereby improving the user experience, and further comprising a holding groove 2 arranged at the middle end of the outer sides of the two groups of clamping arms 1, wherein the holding groove 2 is arc-shaped and has anti-slip grooves therein to improve friction and facilitate force clamping, and a group of clamping mechanisms 3 for clamping are hingedly connected at the front ends of the two groups of clamping arms 1.

[0023] See also Figure 1-4 The utility model provides a pair of tweezers for clamping cell cryopreservation tubes. The components of the two groups of clamping mechanisms 3 are the same. The clamping mechanism 3 includes a clamping piece 31, a clamping block 32 and a limiting mechanism 33. The rear top of the clamping piece 31 is hinged to the front top of the clamping arm 1. The clamping piece 31 can rotate 0-90° around the front top of the clamping arm 1, and the opposite surfaces of the two groups of clamping arms 1 are each provided with a group of clamping blocks 32. The opposite surfaces of the two groups of clamping blocks 32 are set to an arc shape, and a group of buffer layers are adhered thereto. The buffer layer is made of rubber. Furthermore, a plurality of protrusions are provided on the surface of the buffer layer to increase the friction with the outside of the test tube to prevent the test tube from slipping, and a group of limiting mechanisms 33 corresponding to the clamping piece 31 are provided at the front middle end of the clamping arm 1.

[0024] See also Figure 4 The utility model provides a pair of tweezers for clamping a cell cryopreservation tube. The components of the two sets of limiting mechanisms 33 are the same. The limiting mechanism 33 includes an active cavity 331, a telescopic rod 332, a rotating rod 333 and a limiting block 334. The front middle end of the clamping arm 1 is provided with a set of active cavities 331, a set of telescopic rods 332 are arranged in the active cavity 331, and a damping is arranged at the connection between the telescopic rods 332 and the active cavity 331 to increase the friction force. The front ends of the telescopic rods 332 are rotatably connected to a set of rotating rods 333, and the rotating rods 333 can be rotated around the telescopic rods 332. The retractable rod 332 rotates, and a group of limit blocks 334 are connected to the outer side of the rotating rod 333, wherein the rotating rod 333 and the limit blocks 334 can be completely retracted into the movable cavity 331, and the rear end of the clamping member 31, the front end of the limit block 334 and the side away from the rotating rod 333 are all provided with magnetic adhesive strips, and the clamping member 31 can be adsorbed with the limit block 334.

[0025] Here’s how it works:

[0026] The utility model is placed in a suitable position for use. When it is necessary to take out the test tube in the elongated container, force can be applied to the two groups of clamping members 31 in sequence to rotate them around the front top of the clamping arm 1 so that they are in an "L" shape with the clamping arm 1. Then force can be applied to the limit block 334 to remove it and the rotating rod 333 from the movable cavity 331, and the rotating rod 333 is rotated 180° around the telescopic rod 332, so that the side of the limit block 334 away from the rotating rod 333 contacts the rear end of the clamping member 31 and is adsorbed and fixed by the magnetic adhesive strip;

[0027] Then the tweezers can be inserted into the elongated container, and force can be applied to the holding groove 2 to squeeze the two groups of clamping blocks 32 to clamp the test tube and take the test tube out.
