The third and fourth press-driven guide rods pass through a guide rod through hole on the right side of the press-driven horizontal plate. The hole is fixedly connected to the right side of the pressing plate and is fixed to the right side of the pressing drive horizontal plate by a pressing drive guide linear shaft. A first pressing drive guide positioning plate is provided at the top between the first pressing drive guide rod and the second pressing drive guide rod. A second pressing drive guide positioning plate is provided at the top between the third pressing drive guide rod and the fourth pressing drive guide rod. The pressing drive cylinder drives the pressing plate to apply pressure downwards. The pressing column at the bottom of the pressing plate applies pressure downwards to the PCB board. After applying downward pressure, the bottom of the PCB board is pressed tightly into close contact with the PCB board probe at the bottom of the PCB board carrier and tested.

8. The 8-channel PCB circuit board automatic testing equipment according to claim 1, characterized in that: The operation control component includes an operation control bracket, an operation control connecting arm, an operation control connecting block, an operation control display screen, an operation control keyboard, and an operation control mouse. One end of the operation control connecting arm is connected to the operation control bracket, and the other end of the operation control connecting arm is connected to the operation control connecting block. The operation control connecting block is mounted on a press-drive horizontal plate. The operation control bracket has an operation control display screen on its upper part and a keyboard mounting position on its lower part. The operation control keyboard is mounted in the keyboard mounting position at the bottom of the operation control bracket, and an operation control mouse is mounted on one side of the operation control keyboard. The operation control display screen is electrically connected to the power module.
