PCB drilling protection cover plate

The utility model provides a PCB circuit board drilling protection cover plate, relates to the PCB circuit board processing technology field, and comprises a cover plate body used for protection during PCB circuit board drilling, a clamping assembly used for clamping a PCB circuit board, and a spacing assembly, through controlling the starting of a driving motor, the driving motor drives a driving rocking bar to rotate through a shaft rod, so that the PCB circuit board drilling protection cover plate is realized. The driving support moves along with the rotating track of the driving rocker and drives the first support to move, one end of the first support drives the first gear to rotate and drives the second support to move oppositely or oppositely, and a first bottom plate at the bottom of the first support is opened along the inner side wall of the fixed rack. And at the moment, a second bottom plate at the bottom of a second support is opened in the opposite direction of the inner side wall of the fixed ra
