Collapsible slide miter saw

A foldable miter saw, comprising:

• a base unit comprising a front edge, a rear edge opposite to said front edge, a first side edge between said front edge and said rear edge, a second side edge opposite to said first side edge, a bottom wall extended from said front edge to said rear edge, and a top wall opposite to said bottom wall;
• a worktable rotatably mounted on said base unit, said worktable comprising a turntable, an axle holder facing toward said rear edge and connected to said turntable and an extension member facing toward said front edge and connected to said turntable, said turntable defining a working surface opposite to said bottom wall and corresponding to said top wall, said axle holder defining an axis in parallel to said working surface and extending from said rear edge toward said front edge;
• and
• a cutting unit comprising a support base pivotally connected to said axle holder of said worktable and rotatable relative to said base unit and said worktable, a sliding member slidably coupled to said support base, a cantilever pivotally connected to said sliding member, a saw blade mounted at said cantilever and a driver mounted at said cantilever and adapted for driving said saw blade to rotate, said support base comprising at least one guiding member for allowing said sliding member to slide thereon, said sliding member comprising at least one sliding coupling component coupled to and slidable along said guiding member,
• said cutting unit being turnable about said axis relative to said base unit and said worktable and allowing said worktable and said cutting unit to be folded between a working position where said saw blade of said cutting unit defines with said worktable a predetermined contained angle within 90°˜45° and a folded position where an end face of said saw blade of said cutting unit is disposed in proximity to said working surface and said guiding member and said sliding coupling component are disposed in proximity to said working surface.
