Detector

The utility model relates to the technical field of thermal insulation material detection, in particular to a detector which comprises a detector body, a self-adaptive mechanism is mounted at the top end of the detector body, and the self-adaptive mechanism comprises a mounting groove, a motor, a first screw rod, a placing plate, a moving hole, a sliding hole, a limiting rod, a tension spring, a connecting plate, a guide plate, a concave plate and a limiting plate. Through the limitation of one end of the guide plate, the placing plate drives the material to move, when one side of the material is in contact with one side of the limiting plate, the outer side of the material drives the guide plate to move, the guide plate drives the connecting plate to slide in the sliding hole, and meanwhile the connecting plate drives the limiting rod to move in the moving hole; the guide plate can conveniently move according to the specification of the material, the material can be conveniently and rapidly straightened, the
