Further, selecting a smaller-sized positioning block 3 can save the production cost of preparing the fixture. In the actual production process, those skilled in the art can also appropriately adjust and expand the above range according to needs.

[0043] In some embodiments, the fixing plate 1 further includes at least two fixing holes for fixing the fixing plate 1 to the machine tool.

[0044] Thus, setting the fixing holes on the fixing plate 1 helps to more firmly fix the fixing plate 1 to the machine tool and improve the stability of the tooling fixture.
