<p>A tool (E) having a stud (10) for receiving an attachment (S) includes an opening (16) in the stud (10) and a pin (24) movably mounted in the opening. The opening (16) defines upper and lower ends (18, 20), and the lower end (20) located at a portion of the stud (10) constructed for insertion into the attachment (S). The pin (24) is constructed to engage and release the attachment (S). An actuating element (34) is movably positioned on the stud (10), and is coupled to the pin (24) to move the pin (24) from the engaging to the release position. An anti-rotation key (54) is positioned between the actuating element (34) and the stud (10) to slide in a groove (52) formed in either the actuating element or the drive stud and thereby to limit rotation of the actuating element (34) and side loading of the pin (24). A resilient retaining element (56) can be positioned in a recess in either the actuating element (34) or the stud (10) to limit movement of the actuating element (34) relative to the stud (10).</p> |
