BLADE ATTACHING DEVICE, CHISEL AND ITS BLADE, REPLACEABLE CHISEL BLADE, AND ADAPTER FOR ATTACHING REPLACEABLE CHISEL BLADE TO BLADE ATTACHING MEMBER

摘要

To provide a blade attaching device for attaching a blade of a force-cutting tool to an impact tool while suppressing deformation of the blade.SOLUTION: A blade attaching device 10 attaches a blade 810 of a force-cutting tool to an impact tool 900, in which the blade cuts a cutting object when the blade is forced to advance. The blade attaching device 10 comprises a blade attaching part 400 for attaching the blade 810 to the blade attaching device 10 and a tool attaching part 100 which is fixed onto the blade attaching part 400 in order to attach the blade attaching device 10 onto the impact tool 900. On a distal end of the blade attaching part 400, a taper hole 408 is provided, which is complementary to an inclined surface formed on a grip end 813 of the blade 810. In addition, the tool attaching part 100 is formed with a through hole 139 orthogonal to a central axis C and a center hole 138 which reaches a through hole 939 from a Front end surface of the tool attaching part 100 along the central axis C.SELECTED DRAWING: Figure 3
