Claims

[Scope of Claim for Utility Model Registration] (1) An adapter having a mounting portion for a drilling attachment at the rear and a male fitting protrusion at the front, and the male fitting protrusion of the adapter being fitted into the rear. a claw body having a female fitting hole portion; and a proximal outer peripheral portion of the male side fitting protrusion of the adapter, which are integrally formed in two rows spaced apart in the axial direction of the adapter, and have a protrusion and a recess. A pair of engaging parts that have a concave and convex ring shape arranged alternately in the circumferential direction, and the positions of the convex part and the concave part in the circumferential direction match each other, and the adapter can rotate in the circumferential direction between these two engaging parts. a generally inverted U-shaped stopper which is attached to the outer peripheral edge and has a protruding part and a recessed part corresponding to the protruding part and the recessed part; and each of the engaging parts on the inner peripheral part of the female side fitting hole of the claw body. a pair of locks provided at positions corresponding to the respective engaging portions, each having a concave portion that engages with the convex portion of each of the engaging portions and a convex portion that engages with the concave portion to position the claw body around the axis; and a pair of locking parts of the claw body, and the stop metal fitting is rotated from the outside of the claw body so that its protruding part corresponds to the concave part, and the claw body is removed from the adapter. A stopper operation hole for fastening;
A claw member of a drilling attachment, comprising: (2) A convex temporary fixing part is provided on at least one side of an arbitrary protruding part of the stopper, and when the stopper is rotated to a position where the claw body is prevented from coming off, the convex temporary fixing part Claim characterized in that a concave temporary fixing part is provided on the side surface of the convex part of the claw body corresponding to the nail body to temporarily fix rotation of the stopper by fitting and locking the convex temporary fixing part. The claw member of the excavation attachment according to item 1.
