A foldable supporting stand for a portable electronic device includes: a base body having front and rear sides; two front legs adapted to hold the electronic device and coupled to the base body in proximity to the front side, the 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 the base body in proximity to the rear side and that can be folded to move toward the front legs, or unfolded to move rearward and away from the front legs, and a rear leg extension foldably connected to the rear leg body. The rear leg body defines a receiving space for the rear leg extension to be received therein.

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; anda 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, andwherein 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, anda 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. 2. The foldable supporting stand of claim 1, wherein each of said front legs includes:an upper pivot part;a lower end that is opposite to said upper pivot part;a stopper connected to said lower end;a second pivot shaft extending into said base body and said upper pivot part, said second pivot shaft being engaged with said upper pivot part of co-rotation; anda resilient second sleeve member sleeved around said second pivot shaft and inserted non-rotatably in said base body, said second sleeve member gripping resiliently said second pivot shaft to limit said second pivot shaft from rotation when no external force is exerted on said second pivot shaft. 3. The foldable supporting stand of claim 2, wherein said lower end of each of said front legs has a substantially U-shape, and includes two substantially parallel plate sections, and a bottom plate section interconnecting bottom ends of said parallel plate sections, said stopper including a folding arm that has a bottom pivot part received between said parallel plate sections, a pivot pin connecting pivotally said bottom pivot part to said parallel plate sections, a top free end, and a plurality of anti-slip grooves disposed between said top free end and said bottom pivot part, said bottom pivot part having an abutment face abutting against said bottom plate section when said folding arm is unfolded. 4. The foldable supporting stand of claim 1, wherein said frame includes two spaced apart inner walls bounding said receiving space, two wall protrusions respectively protruding into said receiving space from said two inner walls, and two wall recesses respectively indented from said two inner walls; and wherein said rear leg extension includes two outer sidewalls to respectively face said two inner walls when said rear leg extension is received in said receiving space, two sidewall protrusions respectively protruding from said two outer sidewalls to respectively engage said wall recesses, and two sidewall recesses indented from said outer sidewalls to respectively engage said wall protrusions. 5. The foldable supporting stand of claim 2, wherein: each of said first and second pivot holes includes a circular hole section, and a radial hole section extending radially from said circular hole section; andeach of said first and second sleeve members has a substantially C-shaped cross section disposed within said circular hole section, and a radial projection extending into said radial hole section to restrict rotation of said first or second sleeve member. 6. 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; anda 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, andwherein said base body further has a front panel disposed at said front side, left and right spaced apart pivot parts extending downwardly from said base body in proximity to said rear side, a first gap that is formed between said left and right pivot parts and that opens at said rear side of said base body to receive a part of said rear leg, and two second gaps each of which is formed between said front panel and one of said left and right pivot parts and each of which opens at one of left and right sides of said base body to receive a part of one of said front legs, said part of said rear leg being pivoted to said left and right pivot parts, said part of each of said front legs being pivoted to one of said left and right pivot parts. 7. The foldable supporting stand of claim 6, wherein said base body further has a first pivot hole extending through at least one of said left and right pivot parts, a first pivot shaft extending into said first pivot hole and said part of said rear leg, two second pivot holes each extending through one of said left and right pivot parts, and two second pivot shaft each extending through one of said second pivot holes and one of said parts of said front legs.
