Mechanical test tool frame for simulating stress of multiple support lugs

The utility model relates to the field of mechanical simulation experiments, in particular to a mechanical test tool frame simulating stress of multiple supporting lugs, which comprises a front tool frame and a rear tool frame which are connected with box body supporting lugs, the front tool frame is rotatably connected with the four box body supporting lugs through rotating shafts, and the rear tool frame is rotatably connected with the box body supporting lugs through rotating shafts. The front tool frame is rotationally connected with the first force application load, the rear tool frame is rotationally connected with the four box body supporting lugs through the rotating shafts, and the rear tool frame is rotationally connected with the second force application load. According to the utility model, the tool frame is divided into the front tool frame and the rear tool frame, so that the front tool frame and the rear tool frame are separated, and different loads are respectively applied to the front tool fr
