Circuit board detection device capable of adjusting spacing

The invention discloses a circuit board detection device capable of adjusting spacing, and relates to the field of circuit board detection equipment. According to the invention, the translation assembly can be driven by the driving assembly to drive the plurality of sliding sleeves to diffuse and move outwards so as to adjust the size of the distance between the adjacent detection probes, and the distance between the adjacent detection probes is always the same in the adjusting process; therefore, the detection mechanism can detect circuit boards with different models and different pin distances through the detection probes, and meanwhile, the translation rack and the lifting transmission assembly are matched to perform lifting adjustment on the detection probes on each sliding sleeve, so that the redundant detection probes can be moved upwards to be collected according to the number of the pins on the circuit boards; therefore, the number of the probes used for detection is just the same as the number of the
