The utility model discloses a tube stretching test clamp of a universal tester. One of two clamping blocks and two tangent surfaces of external cylindrical surface of an arc test sample (7) together form a V-shaped groove surface, the surface of the other clamping block (2) which is tangent with the internal cylindrical surface of the arc test sample (7) is an outwards-protruded semi-cylindrical surface, a jaw is further equipped with carrier rods which are respectively in lapped joint with the two clamping blocks (1, 2). By utilizing the technical scheme, the utility model can realize exchange of stretching test and arc test sample stretching test without any other auxiliary device. The tube stretching test clamp has the advantages of wide retaining range, strong universality and convenient installation without limitation of sizes of tube diameter or thickness of tube wall and without flattening process for the clamping ends of the arc test sample, and further increasing accuracy of test.
