[0002] An impact testing machine refers to a material testing machine that applies impact test force to the specimen to conduct an impact test. Impact testing machines are divided into manual pendulum impact testing machines, semi-automatic impact testing machines, digital display impact testing machines, microcomputer-controlled impact testing machines, drop-weight impact testing machines, and non-metallic impact testing machines. By replacing the pendulum and the specimen base, two types of tests, simply supported beam and cantilever beam, can be achieved. A drop-weight impact testing machine is another type of impact testing machine, which is suitable for drop-weight impact tests on ferritic steel (especially various pipeline steels). However, the existing impact testing machines have a drooping structure as the impact head, so when performing maintenance, the user needs to bend over and rotate the maintenance tool from bottom to top, which can easily affect the user's experience during maintenance.
