TOOL FOR INSTALLATION OF BOTH TANGED AND TANGLESS WIRE INSERT

摘要

A multi-purpose tool (10) for inserting tanged or tangless wire inserts (13, 11 respectively) in a pre-threaded hole. In the case of a tangless insert (11), the tool nose (21) passes freely through the internal diameter of the insert (11) until a tool pawl automatically engages a cut out (52) formed in the tangless insert (11). Once the proper depth of the insert (11) in the parent material has been achieved, the tool (10) stops rotating and is reversed for proper disengagement, the installation being complete. In the case of a tanged insert (13), the nose (21) of the tool (10) does not pass freely through the insert (13) due to the presence of the tang (15) that is blocking its way. As the tool (10) rotates through the internal diameter of the insert (13), a ledge (60) formed on the nose portion (21) of the tool (10) forces the insert (13) to wind itself in the threads of the parent material. The pawl used to install the tangless insert (11) is positioned directly behind the nose (21) of the tool (10) and remains inoperable in the retracted position since the insert (13) does not have a cut out provided for it. After proper depth of the insert (13) has been achieved, the tool (10) stops rotating and is reversed for proper disengagement. IMAGE
