Abstract: A button lock that selectively retains the angle of an object relative to a handle. The button lock is rotatable between an engaged position, where the angle is retained, and a disengaged position, where the object is disengaged from the handle and can pivotally move about the handle to change the angle. In the engaged position, button teeth on the button engage with handle teeth on the handle. In the disengaged position, the button teeth disengage the handle teeth to space the button from the handle and therefore allow free movement of the handle about the button. The button therefore quickly and easily retains the angle between the object and the handle.
