Insertion rod type temperature controller without action temperature setting deviation

The utility model relates to an inserting rod type temperature controller without action temperature setting deviation, and belongs to the technical field of mechanical temperature controllers. The temperature controller can rectify and eliminate temperature setting deviation generated when the highest action temperature is set, and it is guaranteed that the action temperature set every time in the long-term use process of the electric water heater is accurate and free of temperature deviation. The temperature sensing assembly is composed of a nickel iron rod and a temperature sensing copper pipe, a threaded section at the upper end of the nickel iron rod is in threaded connection with a temperature adjusting nut, a knob sleeved outside the temperature adjusting nut is connected with the temperature adjusting nut in a straight line matching mode, and the lower end face of the temperature adjusting nut is in contact connection with a bearing plate through a gasket. A temperature correction mechanism is arrange
