[0002] During the production process of diamond composite sheets, impact toughness detection is required to master the performance of this batch of products. When conducting the detection, the diamond composite sheet needs to be fixed on the fixture of the pendulum impact testing equipment first. The impact hammer equipped with the equipment is raised to a certain height and then freely falls to impact the diamond layer of the diamond composite sheet. The impact step is repeated until the diamond layer is damaged. The more times of impact resistance, the better the impact toughness of the diamond composite sheet. When the traditional fixture is clamped, due to the certain gap in the guide rail for controlling the falling hammer, the position where the composite layer is impacted changes slightly each time, and the impact part is the side of the composite layer, which does not conform to the actual use situation and affects the accuracy of the detection; the operator also needs to operate under the falling hammer at a certain height, which has a certain safety hazard.
