Mechanical sample preparation clamp without inlaying metallographic sample

The invention provides a mechanical sample preparation clamp without inlaying a metallographic sample, comprising: a support provided with an accommodating space; the loading sample clamp is arranged in the accommodating space, and an assembly hole for placing a sample is formed in the loading sample clamp; the active pressing assembly is arranged on the support, the end face of the side, facing the sample loading clamp, of the active pressing assembly is provided with a protruding part corresponding to the assembly hole, and the active pressing assembly can move in the vertical direction and make the protruding part abut against the sample in a pressing mode. According to the embodiment of the invention, the sample is fixed by loading the sample clamp, so that the aim of directly mechanically preparing the sample without inlaying can be fulfilled, the inlaying cost can be effectively reduced, and meanwhile, the stable, safe and reliable sample preparation quality can be ensured. 本发明提供一种无需镶嵌金相试样的机械制样夹具，包括：支架，
