The utility model relates to a multifunctional fatigue tester. The traditional fatigue testers have the problems of complex structure, high manufacturing cost, single function and the like; and for most testers, the destroy of the integral workpiece is considered, the invalidation critical point of the material is judged through the identification of human eyes and the like, but the destroy process of the surface topography is not captured in time, and the crack extension degree is not properly considered. The fatigue tester comprises a machine frame (3), wherein the machine frame is provided with a screw rod (4); the screw rod is connected with a loading lever (5); and weights (7) are suspended on the loading lever. The machine frame is provided with a first shaft support (8); the first shaft support is connected with a high-speed motor (1) through a belt drive unit (2); and the first shaft support has a transverse position and a vertical position. The fatigue tester is used for fatigue detection on actual w
