Patent ID: 8621971

Claim:
A cutting apparatus comprising: a bottom board; a main adjustable mechanism attached to the bottom board, comprising a mounting member, and a rotatable member rotatably attached to the mounting member; a limiting slot defined in a free end of the rotatable member, the rotatable member comprising a step extending from an edge of the limiting slot, a clasping piece extending from a free end of the mounting member and received in the limiting slot, a first resilient component located between the mounting member and the rotatable member; the first resilient component is substantially perpendicular to the mounting member; and a cutting mechanism attached to the main adjustable mechanism; wherein the rotatable member can be rotated relative to the mounting member between a first position, where an acute angle is formed between the rotatable member and the mounting member, and a second position, where the rotatable member parallel to and abuts the mounting member; the rotatable member is rotatable relative to the mounting member between a first position, where an acute angle is formed between the rotatable member and the mounting member, and the step is engaged with the clasping piece, and a second position, where the rotatable member parallel to and abuts the mounting member, and the step is disengaged from the clasping piece when the rotatable member is in the second position and a driving device provided with a driving pole engages the rotatable member to pull the rotatable member to move to the second position from the first position.
