The invention relates to a contact induction device for a drill rod linearity detecting device. The contact induction device comprises hinge bases and a supporting board, wherein the hinge bases and the supporting board are fixedly connected to the upper surface of a frame plate respectively, the hinge bases are symmetrically and fixedly connected to the frame plate, a supporting plate is arranged between the two hinge bases in a rotating mode, the end of the supporting plate is located below the supporting board, a spring is arranged on the lower surface of the supporting plate, a touch rod is fixedly connected to the supporting board and the supporting plate in a penetrating mode, the lower end of the touch rod is arranged in the spring, and a contact is arranged on the frame plate under the touch rod. The contact induction device for the drill rod linearity detecting device is simple and compact in structure and convenient to install. A touch sensing mode is adopted to detect the linearity of a drill rod, so that the contact induction device is high in working reliability and detecting accuracy degree.
