Correspondingly, as shown in fig. 5, the number of the pressing columns 314 on the upper pressing plate 31 is the same as the number of the placing positions of the impact samples on the hydraulic clamp 2, and the pressing columns correspond to each other one by one, so that the accuracy in pressing is ensured.

In the process, in order to ensure the stability of the clamping force of the hydraulic clamp 2 in the circulation process, the hydraulic clamp 2 is provided with a hydraulic pressure maintaining device and an energy accumulator which are communicated with a hydraulic cylinder, the hydraulic pressure maintaining device is opened, hydraulic oil of a hydraulic station is output to the hydraulic cylinder to clamp an impact sample, meanwhile, the hydraulic oil is also input to the energy accumulator, the energy accumulator is the hydraulic energy accumulator which is an energy storage device in a hydropneumatic system, when the hydraulic oil is input to the energy accumulator, air in the energy accumulator is compressed, the hydraulic pressure of the hydraulic oil is converted into internal energy of the air, when the hydraulic clamp circulates, the hydraulic pressure maintaining device is closed, the input of the hydraulic oil is disconnected, at the moment, the compression force of the hydraulic oil to the air is smaller than the expansion force of the air, the internal energy of the compressed air in the energy accumulator is released, the compressed air is expanded, the hydraulic oil in the energy accumulator is pushed to enter the hydraulic pump, a certain hydraulic oil is provided for the hydraulic pump in the circulation process, the output stability of the impact sample clamping force is ensured, and the stability of the impact sample in the circulation process is further realized, and the pressure maintaining of the impact sample in the clamping process is realized under the condition that the hydraulic source is disconnected.
