The invention discloses a creep fatigue tester capable of monitoring the shaft diameter change of a circular tube. The creep fatigue tester comprises a sample protection tube, an upper sleeve head, a lower sleeve head, a pressure inlet tube and a locking piece, an upper sealing cover and a lower sealing cover are detachably arranged at the two ends of the sample protection tube respectively; the bottom end of the lower sleeve head is fixed to the lower sealing cover, and a first inserting groove is formed in the top end of the lower sleeve head. A second inserting groove is formed in the bottom end of the upper sleeve head, a third inserting groove is formed in the top end of the upper sleeve head, and a first through hole for communicating the second inserting groove with the third inserting groove is formed in the upper sleeve head; the bottom end of the pressure inlet pipe penetrates through the upper sealing cover and is fixedly connected with the third inserting groove in a sealed and inserted mode, and
