Abstract:

A self-adjusting cable guide can be coupled to a nosepiece assembly having a contact end and can be movable between an extended guide position and a retracted guide position relative to the contact end of the nosepiece assembly. A contact trip arm can be adjacent the cable guide and can have a distal end positioned to contact a cable received within a guide recess of the cable guide. The contact trip arm can be movable between an extended arm position corresponding to an inactive state of the tool and a retracted arm position corresponding to an active state of the tool. In addition, the cable guide can have a non-aligned orientation, in which cooperating misalignment stop surfaces can engage each other to stop movement of the self-adjusting cable guide toward the retracted guide position and an aligned orientation in which movement into the retracted guide position is permitted.
