The invention discloses a sample preparation device of a test piece used for an electrochemical corrosion resistance test. The test piece is in a cylinder state, the sample preparation device comprises a test assembly, a top cover assembly and a bar reinforcement fixation assembly, the top cover assembly is fixed at an upper end of the test assembly, and is adapted to the test assembly; a throughhole used for passing through a bar reinforcement is arranged at the center of the top cover assembly, the bar reinforcement fixation assembly is fixed at the through hole, and is used for sleeving one end of the bar reinforcement; and the test assembly, the top cover assembly and the bar reinforcement fixation assembly are coaxially arranged. The test piece prepared by the sample preparation device cannot generate problem of random displacement of the bar reinforcement, the distance between the bar reinforcement and the outer wall and bottom of the test piece accords with the set requirement,incomplete maintenance of
