Patent ID: 8490528

Claim:
A cutting device comprising: a table capable of placing a workpiece thereon; a cutting unit supported on the table and positioned above the table; a base portion on the side of the table; a support portion on the side of the cutting unit and rotatable relative to the base portion, so that the cutting unit can tilt in the left direction and the right direction; a positioning mechanism configured to position the cutting unit in a vertical position and at a plurality of tilt angles including a first tilt angle and a second tilt angle in at least one of a left direction and a right direction, the first tilt angle being larger than the second tilt angle; the positioning mechanism including: at least one stopper bolt mounted to one of the base portion and the support portion; and a switching rod mounted to the other of the base portion and the support portion and capable of contacting the stopper bolt; the switching rod including a first positioning surface and a second positioning surface for positioning of the cutting unit at the first tilt angle and respectively; the switching rod being rotatable between the first positioning surface and the second positioning surface; and a biasing device configured to bias the switching rod toward an initial position where the second positioning surface can contact the stopper bolt such that as the cutting unit is moved from the first tilt angle to the second tilt angle, the positioning mechanism automatically returns from the setting state for the first tilt angle to the setting state for the second tilt angle.
