Workpiece guiding device

A workpiece guiding device comprising:

• a base having a loading surface on a top thereof, the loading surface adapted to carry a workpiece, the loading surface being formed with a first long slot facing downwardly, said base having a first side that is adjacent to the loading surface, wherein a virtual plane is defined perpendicular to the loading surface, the virtual plane intersecting the first side;
• a supporting component movably positioned on the loading surface of said base, said supporting component having a second long slot formed facing upwardly at a bottom of said supporting component, said supporting component having a supporting side and a side opposite to the supporting side, the supporting side and the side opposite to the supporting side being adjacent to the bottom of said supporting component, the supporting side intersecting the virtual plane so as to define an included angle θ, the supporting side adapted to receive a lateral pressing by the workpiece, the second long slot extending to the side opposite the supporting side, wherein the first long slot and the second long slot are vertically opposite to each other so as to define a first space between said base and said supporting component;
• a column-shaped limiting component removably positioned in the first space, wherein a radial periphery of said column-shaped limiting component enters the first long slot and the second long slot so as to limit a relative position of said base and said supporting component in the first space and to fix the included angle θ;
• and
• a pair of clamping structures that respectively clamp said base and said supporting component.
