Optical imaging detector

The utility model discloses an optical imaging detector, which relates to the technical field of detectors and comprises a main body, a movable plate is slidably mounted on the side surface of the main body, two mounting plates are slidably mounted on the upper surface of the movable plate, and the side surfaces, close to each other, of the mounting plates are movably contacted with two sides of the detector. Two limiting plates are installed on the side faces, close to each other, of the installation plate in a sliding mode, and the side faces, close to each other, of the limiting plates make movable contact with the two sides, away from the installation plate, of the detector. According to the utility model, detectors with different sizes can be conveniently limited, the phenomenon that the detectors shake in the detection process is avoided, the detectors are driven to move through the motor, the detectors can conveniently detect soil on the ground, and the detectors and the lens are prevented from being i
