Claim Text:
1. A quick adjustment mechanism for use between a handle which has a first longitudinal axis and an implement which defines a planar surface having a second longitudinal axis and a first lateral axis, said second longitudinal axis extending in a same general direction as said first longitudinal axis, said adjustment mechanism used for altering a handle-to-implement angle easily and quickly, the handle-to-implement angle being altered being the angle defined between said first longitudinal axis of said handle and said second longitudinal axis of said planar surface, said mechanism comprising: a) a first element secured to a handle; b) a second element secured to an implement, one of said first and second elements comprising a toothed member, said toothed member comprising at least one spline wherein said spline includes a first base diameter from which said teeth extend, a non-toothed cylindrical portion adjacent to a row of teeth on said spline, said non-toothed cylindrical portion having a second base diameter, said second base diameter equaling said first base diameter; c) fixation means associated with the other of said first element and said second element engaging said toothed member to prevent relative angular movement between said first element and said second element; d) a mechanism to permit said fixation means to be disengaged from said toothed element whereby said first element and said second element may be angularly moved to adjust the handle-to-implement angle.
