[0004] However, during actual use, this structure can often only achieve a unidirectional extrusion cutting operation. During the cutting process, the force on the extruded side of the PCB board is often too large, which can easily lead to deformation problems in some areas of the PCB board during the cutting process, and it is impossible to perform a decisive and stable cutting operation. At the same time, during the cutting process, the equipment is often unable to quickly load and unload the PCB board, and the debris generated by the cutting inside the equipment cannot be quickly collected and processed, which cannot meet daily use needs. In order to solve the above technical problems, this application proposes a PCB board quick cutting device. Utility Model Content
