JAW GRIP FORCE ADJUSTMENT SYSTEM FOR OFFSET AND 90 DEGREE PULLING HEADS

摘要

The invention provides a system configured to adjust a jaw gripping force of a pulling head. A locking nut is threadedly attached to the pulling head and defines an aperture which extends therethrough. A frame adaptor is at least partially positioned within the aperture of the locking nut. The frame adaptor further receives a portion of the pulling head and a piston of a power tool within an aperture thereof, with the portion and the piston engaging one another within the aperture of the frame adaptor. The portion of the pulling head is operatively associated with a jaw of the pulling head. An adjustment nut is threadedly attached to the frame adaptor. Rotation of the adjustment nut, with the locking nut in an unlocked position, causes the jaw gripping force of the pulling head to either be strengthened or weakened, depending on the direction of rotation.
