Temperature sensor

A temperature sensor disclosed by the present invention comprises a battery assembly and a temperature sensor assembly arranged at the top of the battery assembly, the temperature sensor assembly comprises a mounting frame and a first heat collection plate arranged at the bottom of the mounting frame, and limiting rods are fixedly mounted on both sides of the top of the battery assembly. A strip-shaped groove is formed in the bottom of the first heat collection plate, and an adjusting assembly is arranged in the strip-shaped groove. When the top surface of the battery assembly is not flat, blocking of the stop unit to the limiting assembly can be relieved through the adjusting assembly, so that the limiting assembly extends outwards and is matched with the limiting rods, and the mounting frame and the temperature sensor assembly are locked between the two limiting rods; and the limiting assembly does not extend outwards to be clamped with the limiting rod, so that the mounting frame cannot be mounted, and the
