Thermocouple temperature measuring device

The utility model discloses a thermocouple temperature measuring device. The thermocouple temperature measuring device comprises a base, an axial member, a clockwork spring, a thermocouple wire and a limiting structure. The axial part is rotationally connected with the base; the clockwork spring is arranged on the axial part in a sleeving manner and is connected with the axial part; the thermocouple wire comprises a first section, a second section and a third section which are connected in sequence, and the second section is wound on the periphery of the clockwork spring along the outer ring of the clockwork spring; when the limiting structure is in a first state, the axial part can rotate freely; and when the limiting structure is in the second state, the axial piece is limited to rotate. According to the thermocouple temperature measuring device provided by the utility model, the thermocouple wire can be automatically wound, so that the problem that the efficiency is too low when the thermocouple wire is ma
