Because the hanging workpiece has various component forms, compared with most plate-shaped and block-shaped workpieces, the position can be fixed by clamping during testing. When the workpiece is a chain-like workpiece such as a chain, the chain-like workpiece can be wound between the two clamping plates, and then the corresponding hardness test can be realized by cooperating with the test operation of the device. The guard plate 4 is arranged in front of the two positive and negative silk linear module 2 on the mounting seat 1, the guard plate 4 has high strength and rigidity, and can block the splashed workpiece, thereby protecting the important driving part of the positive and negative silk linear module 2, to ensure the normal operation of the device. The support seat 5 is arranged on the top of the mounting seat 1, the swing frame 6 is rotatably arranged on the support seat 5, the swing frame 6 is a front and back amplitude rotating swing, the rotating rod 7 for holding is arranged on one side of the swing frame 6, and the impact cylinder 8 for knocking the workpiece is rotatably arranged at the end of the swing frame 6.
