[0002] PCB board is called printed circuit board or printed circuit board. It is an electronic component etched on the surface of insulating and non-adhesive copper-clad pressure plate using electronic printing. Since various electronic components need to be installed on the surface during its specific production, it is necessary to open holes on its surface. In this working process, corresponding drilling equipment is needed to operate. The existing PCB board processing and drilling devices can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] When drilling holes in a PCB board, a PCB board processing and drilling device widely used on the market needs to use a specific fixture to fix the PCB board, and then adjust the position of the PCB board through the bottom driving chassis, and finally drill holes in the PCB board through a drilling machine. However, in actual operation, when drilling holes in PCB boards of different sizes is required, a lot of time is required to replace the fixture, and the existing fixture has a poor fixing effect, which easily causes the PCB board to shift during the processing. Therefore, we propose an anti-shift PCB board processing and drilling device to solve the above problem. Utility Model Content

[0022] When the PCB needs to be drilled and fixed, the handles 14 on the two groups of slide bars 12 need to be pulled upward. The two groups of pressing plates 13 drive the slide bars 12 thereon to slide upward along the fixing sleeve 11, and the fixing sleeve 11 squeezes the return spring 15 outside the slide bars 12, and then the PCB to be processed is placed on the placement table 4, and then the rotating cap 8 is rotated to allow the threaded rod 6 to rotate along the threaded seat 5, so that the two groups of pressing plates 13 can move in opposite directions under the guidance of the threaded rod 6 and the two groups of guide slide blocks 10, so that the two groups of side clamps 7 can move smoothly to both sides of the PCB, and then the upward pulling force on the handles 14 is released, and the return spring 15 outside the slide bar 12 releases the elastic force to push the pressing plates 13 downward, so that the two groups of pressing plates 13 move to the upper ends of both sides of the PCB, forming downward pressure on the PCB, thereby further improving the fixing effect of the PCB and preventing the PCB from shifting during the drilling process.
