[0002] Before metallographic sample preparation, the parts to be tested need to be cut. The current metallographic sample cutting machine often uses the cutting device to approach the clamped object by pulling the operating handle to cut. Although some metallographic sample cutting machines are equipped with mechanical control structures, there are certain safety hazards. To this end, China Utility Model Patent CN218746429U provides a metallographic sample cutting machine, which includes a cutting machine base, a cutting machine top cover, a clamp, a cutting assembly, a rotating hand lever, a push block and a limit assembly, etc. The cutting assembly includes a motor installed on the body and driving the cutter disc; by setting a limit assembly on the metallographic sample cutting machine, by pulling the cutting machine top cover, the push block pushes the push plate of the limit assembly to move downward and the first spring reacts to push the push plate upward, and the first gear moves up and down synchronously. Because the first gear is a fixed gear, when it is meshed with the second gear and the third gear, it is limited to rotate, and then the rotation of the fourth gear meshed with the third gear is limited, thereby limiting the rotation of the rotating hand lever, realizing the start of the cutting machine due to accidental touch, thereby reducing the possibility of harm to the operator caused by the cutting machine and improving the advantages of operational safety. Then, the motor in the cutting assembly is easily corroded by the cutting fluid, and long-term use may cause safety accidents. At the same time, for large metallographic sample cutting machines, the top cover of the cutting machine is heavy, which makes it inconvenient to turn the hand lever.
