4. The cantilever assembly method for the sensitive core of a thin-film sensor as described in claim 3, characterized in that: The fastening components include a screw and a nut, with the screw passing through the T-shaped tooling slot and the cantilever beam slot to be fastened to the nut.

5. The cantilever assembly method for the sensitive core of a thin-film sensor as described in claim 1, characterized in that: The first tooling assembly groove is adapted to the shape of the outer side wall of the lower sheath.

6. A cantilever assembly method for a thin-film sensor sensitive core as described in claim 1 or 5, characterized in that: The first tooling assembly plane includes a plurality of first tooling assembly grooves arranged at intervals along the left-right direction; the first tooling assembly grooves have different sizes to accommodate lower sheaths of different sizes.

7. The cantilever assembly method for the sensitive core of a thin-film sensor as described in claim 1, characterized in that: The mounting plane of the boss tooling includes a plurality of boss tooling grooves arranged at intervals along the left-right direction; the boss tooling grooves have different sizes to accommodate metal protective tubes of different sizes.

8. The cantilever assembly method for the sensitive core of a thin-film sensor as described in claim 1, characterized in that: It includes multiple boss fixtures; the multiple boss fixtures are sequentially connected to extend the length of the boss fixture groove.
