<p>A tool housing (12) includes first and second coaxial openings (26, 44) on opposite sides of the housing (12). Wall structure (34) is provided for guiding the key head (32) into the interior of the housing (12), where the key head (32) is engaged by retaining structure (38). The second opening (44) has an ejector member (42, 70) mounted therein for movement toward and away from the first opening (26). When the user of the tool wishes to eject the key (16) from the housing (12), he pushes on the outer portion (58, 72) of the ejector member (42, 70), causing the portion (60, 82) of the member (42, 70) innermost to the housing (12) to contact the key head (32) and to disengage and displace it outwardly through the first opening (26), thereby releasing the key (16) from the housing (12).</p> |
