The detector comprises a transverse rail, a rotating shaft is fixed in the middle of the lower end face of the transverse rail and mounted in a shaft seat, the shaft seat is fixed on the ground, the transverse rail is parallel to the ground, and two ends of the transverse rail are respectively provided with a clamping and positioning device. One-time parking can ensure that the lens of the detector directly faces the headlamp, the driving longitudinal line of the vehicle is perpendicular to the lens, the vehicle does not need to be moved back and forth, and the detection precision and the detection efficiency are high.
