This application discloses a fracture-resistant tensile clamp for a push-pull force gauge, comprising a base, a force gauge, and a clamp. The force gauge is fixed on the base, and the clamp is used to hold the product under test. The base has a slide rail cavity, in which a slider is slidably fitted, and the slider is rigidly connected to the clamp.
