[0022] In specific implementation: the low-temperature storage tank 5 can be opened through the first sealing plug 6, and the test tube containing blood and semen can be placed in the test tube support rack 9 by opening the second sealing plug 11, and the test tube support rack 9 is placed in the low-temperature storage tank 5, and then the second sealing plug 11 and the first sealing plug 6 are threadedly connected to perform sealing operation.

[0023] A first connecting internal thread 7 is provided at the top of the inner side of the low-temperature storage tank 5, a first connecting external thread 8 matching the first connecting internal thread 7 is provided at the outer side of the bottom of the first sealing plug 6, a second connecting internal thread 12 is provided at the inner side of the placement through hole 10, a second connecting external thread 13 matching the second connecting internal thread 12 is provided at the outer side of the second sealing plug 11, a cavity 18 is provided in the second sealing plug 11, a lifting plate 19 is connected to the bottom of the cavity 18, a spring 27 is connected to the top of the lifting plate 19, and a stabilizing column 20 extending to the outside is connected to the bottom of the lifting plate 19.
