Circuit board with positioning mechanism

The utility model provides a circuit board with a positioning mechanism, which comprises a circuit board body, and the circuit board body is provided with a positioning pin assembly, a positioning block assembly and a positioning clamping plate assembly for positioning multiple parts of the circuit board body, so that errors caused by single positioning are prevented, and the positioning effect is further improved. The side edge of a circuit board body is positioned through a positioning pin in the positioning pin assembly and a circuit board positioning arc groove, the positioning sliding block transversely slides above a positioning sliding rail in the positioning block assembly, an L-shaped positioning block above the positioning sliding rail is effectively clamped to the surface of a limiting block in a sliding mode, and the positioning of the side edge of the circuit board body is achieved. The anti-static circuit board has the advantages that four corners of the circuit board body can be effectively pos
