NOVELTY - The utility model model claims a graphene PCB board capable of shielding electromagnetic, relating to the technical field of PCB board. graphene a base, the left and right two ends of the base are fixedly installed with two groups of shielding box the upper end of the two groups of the shielding box fixedly installed with a shielding plate, the upper end of the base left and right two sides of the sliding connection with two groups of seat, the mobile is seat with a groove, the movable seat is provided with a clamping groove, the shielding box hinged with a sealing door, the sealing door is fixedly installed with a handle. The utility model drives two groups of movable seat to do relative movement through two groups of bidirectional thread rod so as to adjust the position of the movable seat, the card block with the clamping groove, the PCB board is fixed, so as to realize the PCB board with different sizes for fixing, without special customization for PCB board with different sizes, there is no need to dismount the device to adjust, which improves the working efficiency.
