Flexible locater triaxial loading fatigue test tool equipment

The utility model relates to three-way loading fatigue test tool for a flexible positioner. The flexible positioner at least comprises a vertical force applying device, a transverse force applying device and a longitudinal force applying device, wherein the vertical force applying device, which is vertically arranged above the tested flexible positioner, is vertically contacted with the tested flexible positioner; the transverse force applying device and the longitudinal force applying device are horizontally arranged and are perpendicular to each other, and the transverse force applying device is contacted with the tested flexible positioner in a horizontal direction; and the longitudinal force applying device is contacted with the tested flexible positioner in a horizontal direction perpendicular to the transverse direction, and applies a longitudinal testing force to the tested flexible positioner. The vertical force applying device, the transverse force applying device, and the longitudinal force applying device act concertedly to fulfill the three-way fatigue test to the tested flexible positioner in perpendicular, transverse and longitudinal directions.
