NOVELTY - The utility model claims a temperature sensor fixing device, comprising a first shell; the second shell and the sensor main body; the bottom of the inner side wall of the first shell and the second shell adjacent to one side are provided with a column groove; and the inner part of the column groove is inserted with a propping column; one end of the propping column located in the column groove is welded with a limiting ring, and the other side outer wall of the limiting ring far away from the propping column is welded with a spring; the holding column is glidingly connected in the column groove through the action of the limiting ring and the spring; and the other end of the holding column far away from the column groove is welded with a clamping block. The propping column of the utility model pushes the clamping block to clamp the sensor main body through the action of the limiting ring and the spring, so that the sensor main body is more stable and firm in the shell; the first shell and the second shell are jointed and fixed by the locking bolt; so that the sensor main body can obtain better protective effect in the first shell and the second shell, so as to prolong the service life of the sensor main body.
