Foldable miter saw with safety device

A foldable miter saw with safety device, comprising:

• a base unit comprising a substantially horizontal working surface and an axle holder connected to said working surface, said axle holder forming a folding axis parallel to said working surface;
• and
• a cutting unit comprising a rotating member arranged on said axle holder so as to rotate around said folding axis, a supporting arm pivotally connected to said rotating member, a blade pivoted to said supporting arm, a handle connected to said supporting arm, a driving unit operable to drive said blade to rotate and a safety assembly set on said handle;
• wherein:
• said safety assembly comprises a safety switch and a safety member adjacent to said safety switch, said driving unit being operable to drive said blade to rotate when said safety switch is operated, said driving unit being unable to drive said blade to rotate when said safety switch is not operated, said safety member comprising a pivot end pivoted to said handle and a free end opposite to said pivot end;
• said rotating member is rotatable around said folding axis relative to said axle holder to drive said blade to rotate between a working position and a folded position relative to said working surface, said blade being relatively far away from said working surface when said blade is in said working position, said blade being relatively close to said working surface when said blade is in said folded position;
• during the rotation of said blade from said working position to said folded position, a rotation included angle generated between said blade and said working surface gradually decreases, and said free end of said safety member is rotatable downward under the action of gravity, so that said safety member rotates from a touchable position to an anti-touch position relative to said safety switch, said free end being relatively far away from said safety switch so that said safety switch is operable when said safety member is in said touchable position, said free end being relatively close to said safety switch and said safety switch is not operable when said safety member is in said anti-touch position.
