Zusammenfassung:	The utility model discloses an air quality detector, which relates to the technical field of detection devices, and comprises a base, the left side and the right side of the base are movably connected with positioning pins, the top of the base is provided with a box body, one side of the box body is provided with a motor box, and a driving motor is arranged in the motor box. The output end of the driving motor is connected with a forward screw, the forward screw is fixedly connected with a reverse screw through a connecting block, and the forward screw and the reverse screw are in threaded connection with threaded sliding blocks respectively. According to the device, a driving motor drives a positive and negative screw rod to rotate, a rhombic lifting frame can be used for lifting the height of a detector body by arranging a sliding rail and a thread to slide, and a lifting block is limited on a supporting rod to ensure that the lifting block drives the detector body to lift in the vertical direction, so that
