Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a worktable, and more particularly to a worktable having an adjustable shield movable or adjustable relative to the circular blade, according to work pieces of different thickness, for suitably covering or shielding the circular blade, and for preventing cut chips or particles from flying everywhere.
  • 2. Description of the Prior Art
  • Typical worktables comprise a circular blade rotatably supported in or on a table, and rotated or driven by a motor in order to cut work pieces. While cutting the work pieces, cut chips or particles may be generated and may flying everywhere. For preventing the cut chips or particles from flying everywhere, a fence guard or a shield is provided and engaged onto the circular blade, in order to cover and to shield the circular blade, and to confine the cut chips or particles, and thus to prevent the cut chips or particles from flying everywhere.
  • For example, U.S. Pat.
