Tool structure capable of machining thin-wall long and thin blades stably

The utility model discloses a tool structure capable of machining thin-wall long and thin blades stably. The tool structure comprises a base. The base is provided with a tenon air inlet side pressing block, a blade crown air inlet side pressing block, a tenon air discharge side locating device, a blade crown air discharge side locating device and a blade body backward section high point locating device. The tool structure has the advantages that the technical problem that because blade bodies of single-tooth structure blades are thin and long, the finish sizes of the processes of machining sawtooth crowns, crown tops and the like are poor is solved, the machining quality of the processes of machining the sawtooth crowns, the crown tops and the like of the blades is improved, and the qualification rate of machining is increased.
