Broken piece collecting assembly for fastener setting tool

摘要

In a fastener setting tool (1) having a container (15) for collecting the broken pieces of fasteners such as blind rivets and lock bolts which are fastened by breaking its mandrel, to prevent the broken pieces of the mandrels from being entangling to each other in the collecting container. A fastener setting tool (1) is constructed that the mandrel of a fastener is inserted into a nose (6) at the front end of the tool; the body of the fastener projected from the nose is inserted into the mounting hole of a base member such as a panel; under that condition, the mandrel is pulled enough to break the mandrel to enlarge the shank of the fastener body to fix the fastener by the enlarged shank portion and a flange of the fastener body. The tool also includes a broken piece collecting assembly (30) for collecting, through a path (9) within the tool, the broken pieces (37) of the mandrels, which are broken by the above pulling operation. The broken piece collecting assembly comprises a container (15) encircling the outlet port of the path (9) and extending to elongate the path (9) for collecting the broken pieces (37) as discharged from the path (9); and a broken piece entangling prevention means disposed in the container (15). The broken piece entangling prevention means comprises an elongated broken piece receiver member (31) extending in the container (15) along the axis of the path (9). The broken piece receiver member (31) is provided with an elongated groove (34) to receive the broken piece (37) outputted from the path (9) in its existing posture.
