1. A foldable supporting stand for a portable electronic device, comprising: a base body having front and rear sides; two front legs adapted to hold the electronic device and coupled to said base body in proximity to said front side, said front legs being foldable to move toward each other, or unfoldable to move away from each other in opposite sideward directions; and a rear leg including a rear leg body that is coupled to said base body in proximity to said rear side and that can be folded to move toward said front legs, or unfolded to move rearward and away from said front legs, and a rear leg extension foldably connected to said rear leg body, said rear leg body defining a receiving space for said rear leg extension to be received therein, wherein said front legs are inclined when said rear leg moves rearward, and an inclination angle of said front legs varies when said rear leg extension changes between a folded configuration , in which said rear leg extension is received in said receiving space, and an unfolded configuration, in which said rear leg extension is moved away from said receiving space, wherein said rear leg body includes a frame defining said receiving space, and a rear leg pivot part pivotally connected to said base body, and wherein said base body has: a first pivot shaft extending into said base body and said rear leg pivot part and engaging said rear leg pivot part for co-rotation, and a resilient first sleeve member sleeved around said first pivot shaft and inserted non-rotatably in said base body, said first sleeve member gripping resiliently said first pivot shaft to limit said first pivot shaft from rotation when no external force is exerted on said first pivot shaft.
