[0030] For example, as shown, Figure 1 As shown, the fixing sleeve 110 is provided with a plurality of cutouts 111 spaced along the circumference thereof. Further, the cutouts 111 extend from the first end to the second end of the fixing sleeve 110. That is, the length of each cutout 111 is less than the length of the entire fixing sleeve 110.
[0031] Specifically, in the present embodiment, the fixing sleeve 110 is provided with four cutouts 111 distributed at equal intervals, and the four cutouts 111 are symmetrically distributed. It should be noted that the number of cutouts 111 is not specifically required in the present embodiment, and can be selected according to actual needs.
[0032] In the embodiment, by arranging the plurality of cutouts at the circumferential interval of the fixing sleeve, when the sensing end of the stress sensor is inserted into the fixing sleeve, the fixing sleeve can be allowed to deform to a certain extent, so that the diameter of the fixing sleeve is slightly larger than the diameter of the sensing end of the stress sensor, and the sensing end of the stress sensor is better fixed in the fixing sleeve.
