Tail handle piece, fluorescent optical fiber temperature measurement probe, temperature sensor and temperature measurement system

The utility model relates to the field of optical fiber temperature measurement, in particular to a tail handle piece, a fluorescent optical fiber temperature measurement probe, a temperature sensor and a temperature measurement system. The tail handle piece is assembled on an optical fiber of the fluorescent optical fiber temperature measurement probe, is cylindrical and comprises a tail end section, a middle section and a head end section which are sequentially connected in the axial direction of the tail handle piece, the tail handle piece is further provided with a through hole penetrating through the tail end section, the middle section and the head end section in the axial direction, and the sensing end of the optical fiber of the fluorescent optical fiber temperature measurement probe penetrates through the through hole; a clamping part is formed on the outer surface of the middle section and/or the tail end section, the clamping part is a non-rotating body with the axis of the tail handle piece as the
