The patent does not fix the metal plate from above during use, and the metal plate is prone to warping and deformation. Therefore, the metal plate is not easy to position in this way, and it is easy to shift and affect the cutting accuracy. At the same time, we know that the debris left on the platform during the cutting process causes pollution, and the cutting process is also dangerous. In order to better improve the safety and accuracy of cutting, we propose a positioning device for metal plate cutting. Utility Model Content
