Preferably the retainer assembly is pivotally attached to the main body and/or is movable between a first position contacting the table and a second position bypassing the table. The retaining assembly may pivot about an axis substantially perpendicular to a plane of the table. The retainer assembly may also include an cxtension (19) that contacts underside of the table. The cxtension in turn may include a camming surface contacting the underside of the table.</p> |
