[0002] During the processing of a circuit board, it is usually necessary to drill holes in the circuit board to facilitate the processing and forming of the circuit board.

[0003] A Chinese patent with application publication number CN212793124U discloses a drilling device for circuit board processing. In the patent, an electric push rod is provided to adjust the height of the clamping plate, so that it is suitable for circuit boards of different thicknesses. A clamping plate is provided, and the clamping plate clamps the circuit board through a clamping spring to prevent the circuit board from being displaced during the drilling process, thereby affecting the accuracy of the drilling. In addition, a circuit board protection pad can protect the circuit board to prevent the circuit board from being crushed by the clamping plate during the clamping process.
