[0002] With the popularization and wide application of electronic products, the production and manufacturing technology of printed circuit boards are constantly updated and developed; in the production process of PCB boards, it is necessary to punch holes in the body of PCB boards to facilitate the installation of electronic components. The quality of the hole determines the difficulty of installing the components. If the drilled hole is skewed, it will make it difficult for the pins of the electronic component to be inserted into the hole, which will bring great trouble to the operator.

[0003] Chinese patent (notification number CN 209755422 U) discloses a counterbore processing equipment for PCB circuit boards. A bar-shaped groove is provided at the lower end of the support plate, and a slider is slidably connected to the outside of the slide bar of the bar-shaped groove. According to the needs of the drilling position, the lateral position of the slider is adjusted to increase the range of use of the device, and then the drilling operation can be performed accurately. At that time, the device has no protection mechanism. During the drilling operation, due to machine failure or work Due to personnel's operation errors, the drill bit can easily continue to drill through the workbench or damage the drill bit after drilling through the PCB board, which not only affects the processing efficiency, but also has great danger.
