The invention discloses a PCB tool. The PCB tool can prevent PCBs inserted in the PCB tool from colliding with one another so as to increase the number of inserting boards of the tool and improve the processing efficiency. The PCB tool may comprise a groove clamping assembly, a lower clamping assembly, an upper clamping assembly and a supporting frame, wherein the groove clamping assembly comprises two opposite inserting boards, a plurality of clamping grooves are formed in each inserting board, and a PCB is accommodated between a pair of opposite clamping grooves in the two inserting boards; the lower clamping assembly comprises two lower clamping groups, and is used for clamping the PCBs from the lower part; the upper clamping assembly comprises two upper clamping groups, and is used for clamping the PCBs from the upper part and stretching the PCBs upwards; and the supporting frame is used for connecting the groove clamping assembly, the lower clamping assembly and the upper clamping assembly into one body.
