A support column is each provided with 4 angles of cassette bottom of shape box body, is provided with otic placode at left and right sides of plate, in the plate face of plate
It is provided with pipe sleeve, in the slot of multiple plates insertion box bodys, the otic placode of plate, which is taken, to be put on box wall plate along upper, in the upper of plate
Multiple grooves are provided with along the thickness direction of plate on the end face at edge, switchboard is hinged with the end face of the upper edge of plate,
Switchboard surrounds jack with groove；
The pipe end of freezing straw is connected by connecting axle portion with sheet formed information portion, connection axle portion and the pipe end phase for freezing straw
Be hinged, in freezing straw insertion pipe sleeve, the connection axle portion for freezing straw is placed in the jack on plate.
The utility model is provided with sheet formed information portion in the pipe tail end of freezing straw, and sheet formed information portion is used to record embryo in pipe
Tire information, embryo are enclosed within straw, can also avoid the embryo during keeping in cold storage from being contaminated.By designing conserving case
The structure of built-in inserted plate, freezing straw is inserted in vertical state in liquid nitrogen, and freeze the sheet formed information portion of straw tail end in level
Set, be easy to experimenter to read embryo's information.When needing to take out freezing straw from liquid nitrogen, rotation plate upper edge is opened
Plate is closed, freezing straw being extracted out from pipe sleeve, with can extract monoblock plate out of conserving case out, being easy to picking and placeing for straw.
