The utility model relates to a tester for the bending-lifting follow up stability of a military helmet, which is provided with a U-shaped base. The middle part of the U-shaped base is provided with a U-shaped bracket which is arranged on two side walls of the U-shaped base by the elasticity of a bending fulcrum bearing. A metal head die, an accelerometer, and a displacement sensor are fixed at the middle part of the U-shaped bracket. A trip rod is fixed on one side of the U-shaped bracket. A limiter is arranged on one side wall of the U-shaped base corresponding to the trip rod. A force sensor is arranged in a mouth cavity of the metal head die. The force sensor, the accelerometer, and the displacement sensor are connected with the data of a single chip computer circuit by transmission lines. The utility model can acquire the time curve of the corresponding displacement of the military helmet and the metal head die, and provides a kind of characterization and an objective measure for judging the stability of the military helmet.
