When in use, the temperature sensor is clamped by the card slot 1, and the temperature sensor is driven by the sliding of the support frame 1 to realize the detection of the temperature condition of the outer side of the heating pipe network, and the detection information is transmitted to the external controller through the temperature sensor. The rotation of the rotating shaft drives the rotation of roller one, and under the action of rubber ring one, the rotation of roller one drives support frame one to slide on the upper end of the outer side of the heating pipe network.
