A chuck is slidably mounted on the top of the supporting plate, and a second driving device for driving the chuck to slide. The sliding direction of the chuck is perpendicular to the sliding direction of the supporting plate. This mechanism can automatically push stainless steel bars during processing and can process axial sections at various angles, reducing labor costs and improving production efficiency.

[0004] Based on the aforementioned existing technology, the current pushing mechanism for processing stainless steel bars still has the following problems: when processing stainless steel bars, it is usually necessary to manually push the bars into the processing machine. For some heavy steel bars, it is very difficult for one person to push them. Manual pushing is laborious and time-consuming. Therefore, this utility model provides a pushing mechanism for processing stainless steel bars. Utility Model Content
