Abstract:
1. A tilt adjustment device for adjusting tilt of a left guide bar with respect to a right guide bar in order to dispose the left and right guide bars in the same elevation, the tilt adjustment device comprising: a holding seat; and a cylindrical-shaped bushing disposed rotatably within said holding seat, defining a bar-retention hole adapted to permit extension of the left guide bar therethrough, said cylindrical-shaped bushing having a turning portion defining a first axis, and an insert portion that extends eccentrically from said turning portion and that defines a second axis parallel to said first axis; wherein, rotation of said cylindrical-shaped bushing relative to said holding seat results in a radial movement of said turning portion, which, in turn, moves said first axis toward and away from said second axis of said insert portion.
