Composite pendulum impact testing machine

The utility model relates to the technical field of carrying out one-time impact test on a non-metal material in a room temperature environment to detect the impact toughness of a sample. The utilitymodel relates to a tester, in particular to a combined pendulum impact tester. The defects in the prior art are overcome; the device comprises a machine body part, a pendulum bob hanging part, a pendulum bob, a centering assembly, a jaw part and a brake part, the machine body part is composed of a base, a protective cover and a stand column. According to the utility model, the cost of a laboratoryis reduced while multiple purposes of one machine are ensured; pROTECTIVE COVER OPENING, the testing machine starts safety protection measures; the potential safety hazard caused by falling of the pendulum bob due to misoperation is effectively avoided; the installation of the protective cover can effectively avoid the situation that the sample is difficult to collect after the test due to splashing of the broken sample,
