Abstract:
A cutting apparatus comprising:a base adapted to support a workpiece thereon; a first pivot extending in a longitudinal direction and defining a first axis; a blade-holding arm extending in a transverse direction relative to said longitudinal direction and having a free end and a pivot end that is opposite to said free end and that is pivoted to said base through said first pivot so as to be pivotable relative to said base about said first axis, said first pivot being secured to said pivot end of said blade-holding arm for co-rotation therewith about said first axis; a blade mounted rotatably on said blade-holding arm for cutting the workpiece; a light-emitting unit pivoted to said blade-holding arm at a position between said free end and said pivot end of said blade-holding arm so as to be pivotable relative to said blade-holding arm about a second axis that extends in said longitudinal direction and that is parallel to said first axis, said light-emitting unit being adapted to project a spotlight upon a working area around the workpiece on said base; and a position-adjusting unit including a first linkage that is secured to said first pivot so as to co-rotate therewith, and a second linkage that has two opposite ends which are respectively pivoted to said first linkage and said light-emitting unit in such a manner that pivoting movement of said blade-holding arm relative to said base about said first axis in a first direction results in corresponding pivoting movement of said light-emitting unit relative to said base about said first axis in said first direction and relative to said blade-holding arm about said second axis in a second direction opposite to said first direction to an extent sufficient to maintain projection of the spotlight upon the working area.
