ABSTRACT:
An insertion tool 48 is used to insert a threaded coil insert 26 into a threaded opening 22 of a support structure 20. The tool 48 includes a rotatable mandrel 50 having a first slot 62 for receiving a blade 76, the forward end of which is formed with a drive hook 94. The drive hook 94 is located in an end opening 64 of the mandrel 50 and is selectively movable through a second slot 66 formed in the mandrel. The first slot 64, the second slot 66 and the end opening 64 are in communication. The blade 76 is formed with a nib 78 which is normally biased into a chamber 112, but is selectively precluded from doing so by selective movement of a bushing 110 which is attached to an axially movable sleeve 102. As the threaded insert 26 is placed on a threaded end of the mandrel 50, the sleeve 102 is moved rearward to move the bushing 110 from engagement with the nib 78 whereby the biased nib moves into the chamber 112. The blade 76 thereby pivots to move the drive hook 94 through the second slot 66 of the mandrel 50 whereby the drive hook moves into a drive slot 40 formed in the insert 26. Upon rotation of the mandrel 50 and the blade 76, the insert 26 is driven threadedly into the threaded opening 22 of the support structure 20.
