Such devices are widely used in fields that require high-precision positioning, such as optical fiber cutting, precision machining, and semiconductor manufacturing.

[0003] For example, a blade positioning device for an optical fiber cutter with the publication number CN208188394U includes: a tool holder, on which there is a blade mounting position. The blade mounting position includes a stepped hole for mounting a positioning screw. The large hole in the stepped hole is a clearance hole, and the small hole in the stepped hole is a threaded hole; a positioning screw, including a smooth rod and a threaded rod that are integrally structured.
