Microspur distributed optical fiber temperature measurement sensor

The utility model relates to the technical field of temperature measurement, in particular to a micro-distance distributed optical fiber temperature measurement sensor, which comprises a sensor body and a mounting assembly, and is characterized in that the mounting assembly comprises a mounting box, a supporting mechanism, two guide rods, two clamping blocks, two double-thread screws and a driving mechanism; the supporting mechanism is used for fixing the mounting box at a mounting position, each clamping block is driven by two double-thread screws, when a sensor body is mounted, the sensor body is placed between the two clamping blocks, then the two double-thread screws are driven by the driving mechanism to rotate synchronously, the two clamping blocks are close to each other to clamp the sensor body, and the sensor body is mounted. When the sensor body needs to be taken down, the driving mechanism is used for driving the two double-thread screws to synchronously and reversely rotate, so that the two clampi
