Printed circuit board (PCB) overlapping device

The utility model discloses a PCB (printed circuit board) overlapping device which comprises an overlapping mechanism, the bottom end of the overlapping mechanism is provided with an extrusion mechanism, two sides of the top end of the overlapping mechanism are respectively provided with an insertion plate, and the top end of each insertion plate is provided with a clamp. According to the PCB overlapping device, through cooperative use of the first transverse plate, the second transverse plate, the protruding blocks, the transverse rods, the first sliding blocks and the sliding grooves, the overlapping work of PCBs is achieved, through cooperative use of the inserting plates, the inserting blocks, the clamps and the sliding ways, the overlapping work of the PCBs of different sizes is achieved, and the overlapping efficiency of the PCBs is improved. Through cooperative use of a vertical plate, a supporting plate, a supporting plate, a rolling wheel, a second sliding block, a pressing rod, a button and a spring
