The invention relates to an ovum picking test tube transfer heat insulating device. The ovum picking test tube transfer heat insulating device comprises a base, a rotating motor, a mounting shaft, a fixing sleeve, a support module, N test tube heat insulating modules and N hanging modules for placing the test tube heat insulating modules, wherein the rotating motor is mounted on the base, the rotating shaft of the rotating motor is connected with the mounting shaft; the support module is composed of N hanging rods and N support rods; the fixing sleeve is mounted on the mounting shaft in a sleeve mode, and protrusions are formed inside the fixing sleeve; the mounting shaft is provided with clamping slots matched in a fastened mode with the protrusions; the bottom end of every support rod ishinged to the fixing sleeve, and the top end of the support rod is hinged to the corresponding hanging rod; the top end of the mounting shaft is provided with a hanging rod mounting block; the hanging rods are hinged to the hanging rod mounting block; the hanging modules are mounted on the hanging rods; N is 1-20. The ovum picking test tube transfer heat insulating device can substitute nurses for transferring test tubes to save labor, and meanwhile, can effectively maintain the temperature of the test tubes during transferring to keep the developmental ability of oocytes.
