Since the rack 21 is meshed with the gear, when the rack 21 slides, the second gear 20 can drive the rotating column 19 to rotate, so that the first rotating rod 22 and the second rotating rod 23 push the clamping plate 8 to slide upward along a straight line under the limiting action of the multiple telescopic rods 7, thereby making the clamping plate 8 and the casing 1 The bottom end cooperates with the edge of the front end of the stove to clamp and fix it, so that the device can be stably fixed on the stove, which improves the stability of the device when in use, and starts the first motor 10, so that the first motor 10 drives the first gear 11 to rotate. Since the first gear 11 is meshed with the gear ring 13, when the first gear 11 rotates, the gear ring 13 can drive the battery compartment 9 and the temperature sensor 4 to rotate along the slide 3, so that the temperature sensor 4 can monitor the temperature of the entire bottom of the pot, from point to line monitoring, which solves the problem that the anti-dry burning temperature sensor 4 in the prior art can only monitor one point of the bottom of the pot during actual use, has great limitations during monitoring, and cannot monitor the entire bottom of the pot.
