Ultrasonic detection test block overturning tool

An ultrasonic detection test block overturning tool comprises a supporting bottom plate, two supporting stand columns are arranged on the supporting bottom plate, and a first clamping jaw and a second clamping jaw are hinged to the opposite inner faces of the two supporting stand columns respectively; the hinge axis of the first clamping jaw and one supporting stand column and the hinge axis of the second clamping jaw and the other supporting stand column are coaxial and parallel to the supporting bottom plate, the first clamping jaw and the second clamping jaw are not in contact with the supporting bottom plate, and a space for clamping a test block is reserved between the first clamping jaw and the second clamping jaw. Through reasonable arrangement of component structures, the whole device is simple in structure, a labor-saving rotary tool is adopted to replace manual test block overturning, the labor intensity is reduced, the safety risk is reduced, sampling points of all defects can be completed on the p
