Document Type and Number:
WIPO Patent Application WO/2019/135398
Kind Code:
A1
Abstract:
In the present invention, a blade body of an extruding/cutting tool is attached to an impact tool, and deformation of the blade body is suppressed. A blade body mounting device (10) attaches, to an impact tool (900), a blade body (810) of an extruding/cutting tool that pushes a blade edge to the front to cut an object to be cut. The blade body mounting device (10) comprises: a blade body attachment part (400) for attaching the blade body (810) to the blade body mounting device (10); and a tool attachment part (100) that is fixed to the blade body attachment part (400) and that is for attaching the blade body mounting device (10) to the impact tool (900). On the front end of the blade body attachment part (400), a tapered hole (408) that is complementary to an inclined surface formed on an insert (813) of the blade body (810) is formed. The tool attachment part (100) has formed therein: a through hole (139) that is orthogonal to a center axis (C); and a center hole (138) that reaches a through hole (939) from the front-side end surface of the tool attachment part (100) along the center axis (C).
