Repeated bending tester

A repeated bending tester includes a platform, a track, a moving mechanism, a first fastening unit, a second fastening unit, wheels, and a driving mechanism. The track is disposed on the platform and includes an extending direction. The moving mechanism is slidable on the track along the extending direction. The first and second fastening units are oppositely disposed on the moving mechanism along the extending direction, and can fasten a test sample collectively. The wheels are disposed on two opposite sides of the track, and a line connecting centers of the wheels forms a polygonal area crossing the track. The driving mechanism is coupled to the first fastening unit and can drive the first fastening unit to further drive the moving mechanism and the second fastening unit to move on the track, thereby enabling the test sample to contact the wheels to be bent by the wheels.
