FASTENING TOOL DEVICE ABSTRACT OF THE DISCLOSURE Apparatus for gripping and pulling on an elongated mandrel comprising first means having a supporting surface and at least one opening therethrough for receiving the mandrel. The apparatus also embodies a second means pivot- ally connected to the first means for pivotal movement about a pivotal axis between a first position and a second position. The second means has a mandrel receiving portion which cooperates with the mandrel and is conjointly movable there- with. As envisioned such apparatus includes jaw means oper- atively connected to the second means for movement therewith and for movement relative thereto about said pivotal axis towards and away from the mandrel receiving portion. Such apparatus contemplates biasing means for biasing the jaw means in one direction such that the jaw means contacts the supporting surface whenever the second means is in at least the first position, whereby a mandrel is insertable through the opening and between the receiving portion and the jaw means. The biasing means initially biases the jaw means into contact with the supporting surface while the second means moves towards the second position such that the receiving portion moves towards the jaw means to cause the mandrel to become tightly gripped between it and the jaw means whereupon the continued movement of the second means to the second position moves the jaw means away from contact with the supporting surface and into tighter gripping engagement with the mandrel to forcefully pull gen- erally upwardly on the mandrel. -1-
