Stable temperature transmitting device

The utility model discloses a stable temperature transmitting device, and relates to the field of temperature transmitting devices. The device comprises a thermocouple induction mechanism, a thread installation mechanism and a temperature transmitter which are communicated in sequence. The bottom surface of the temperature transmitter and the thread installation mechanism are coaxially provided with a rotation supporting mechanism. The rotating supporting mechanism comprises a rotating base coaxially fixed to the bottom end of the temperature transmitter and a telescopic mechanism rotationally arranged on the rotating base, the telescopic mechanism and the thread mounting mechanism are coaxially arranged in a sleeved mode, and the bottom end of the telescopic mechanism serves as a bearing end. A thread fixing section of the thread mounting mechanism is arranged on a telescopic path of the bearing end; the problems that when the height of the temperature transmitter is adjusted or the temperature transmitter i
