Double-sided circuit board testing device

The utility model discloses a double-sided circuit board testing device, and particularly relates to the technical field of double-sided circuit boards, which comprises a testing frame and short columns arranged at four corners of the lower end of the testing frame, detection assemblies are slidably mounted on two sides of the upper end of the testing frame, and a weighting mechanism is arranged at the lower end of a supporting mechanism. A long strip is arranged on one side of the main pressurizing mechanism, a long rod is arranged on one side of the upper end of the long strip, when an operator begins to detect, the weighting mechanism is reasonably placed according to tolerance degrees of different circuit boards, after adjustment, a moving rod is moved, the moving rod can drive the long strip and a sliding block to slide in an inner cavity of a sliding groove, and after adjustment is conducted to the needed position, the long rod is moved to the position where the long strip is located.
