摘要： A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.

摘要： A cutting tool holding device, which is for holding a cutting tool, includes a base, a holder, and a limiting set, wherein the holder is disposed on the base, and the limiting set is disposed in a non-circular channel of the base. A connecting shaft portion of the holder is for inserting into a storage hole of the base, wherein the connecting shaft portion includes a shaft body and at least one positioning portion, and the non-circular channel includes an abutting member and a bolt. The bolt is passed through the abutting member, wherein the abutting member is moved to an opening hole of the storage hole along an axis by rotating the bolt so as to push the positioning portion and abut the shaft body.
