1. A supporting structure adapted to be coupled between a framework of a treadmill and a treadbase of said treadmill for enabling said treadbase to be turned relative to said framework between an operative position and a non-operative position and for supporting said treadbase in said non-operative position, said supporting structure comprising:a first locating plate fixedly located on said framework, a second locating plate fixedly located on said treadbase, and a support coupled between said first locating plate and said second locating plate, said support including a first support member and a second support member, said first support member having a first end connected pivotally with said first locating plate, a second end, and a pivot at said second end, said second support member having a first end connected pivotally with the pivot of said first support member and a second end connected pivotally with said second locating plate, whereby said second support member can be turned about said pivot between a first position where said first support member and said second support member are axially aligned and a second position where said first support member and said second support member are folded up, either said first support member or said second support member being retractable and being retracted when said first support member and said second support member are folded up, and an actuating member, said actuating member being fixedly mounted to said first support member for driving said first support member from said first position to said second position. 2. The supporting structure as defined in claim 1 further comprising a return member, said return member being installed on said framework and adapted to provide a rebounding force driving said first support member to move toward said first position.3. The supporting structure as defined in claim 1, wherein said framework is composed of a base frame and a handrail; wherein said treadbase is connected pivotally with either said base frame or said handrail; wherein the contained angle between said base frame and said treadbase is less than 90° when said treadbase is turned to said non-operative position.4. A supporting structure adapted to be coupled between a framework of a treadmill and a treadbase of said treadmill for enabling said treadbase to be turned relative to said framework between an operative position and a non-operative position and for supporting said treadbase in said non-operative position, said supporting structure comprising:a first locating plate fixedly located on said framework, a second locating plate fixedly located on said treadbase, and a support coupled between said first locating plate and said second locating plate, said support including a first support member and a second support member, said first support member having a first end connected pivotally with said first locating plate, a second end, and a pivot at said second end, said second support member having a first end connected pivotally with the pivot of said first support member and a second end connected pivotally with said second locating plate, whereby said second support member can be turned about said pivot between a first position where said first support member and said second support member are axially aligned and a second position where said first support member and said second support member are folded up, either said first support member or said second support member being retractable and being retracted when said first support member and said second support member are folded up, and wherein said first support member comprises two stop plates at an end thereof, wherein said second support member comprises a longitudinal sliding slot at an end thereof; wherein said pivot is fixedly mounted between said stop plates and is running through said longitudinal sliding slot, whereby said first support member and said second support member are pivotally connected with each other. 5. The supporting structure as defined in claim 4, wherein said first support member comprises a stop face; wherein said second support member comprises a mounting endpiece; wherein said longitudinal sliding slot has a top end and a bottom end, the second end of said second support member being supported on said stop face to hold said first support member and said second support member in said first position when the top end of said longitudinal sliding slot stopped against said pivot, said second support member being turnable about said pivot from said first position to said second position when the bottom end of said longitudinal sliding slot stopped against said pivot.6. The supporting structure as defined in claim 5, wherein said second support member is composed of an air cylinder and a piston movable in and out of said air cylinder and connected pivotally with said second locating plate, said air cylinder having an endpiece pivoted to said pivot, said endpiece having said longitudinal sliding slot formed therein.7. The supporting structure as defined in claim 6, wherein said air cylinder has a stop pin extending across said endpiece and spaced above said longitudinal sliding slot; said stop plates each have a stop edge adapted to stop said stop pin when said second support member is turned to said first position.8. The supporting structure as defined in claim 5, wherein said first support member is composed of an outer tube connected pivotally with said first locating plate and a retractable inner rod movable in and out of said outer tube, said retractable inner rod having an outer end extended out of said outer tube and fixedly mounted with said stop plates.9. The supporting structure as defined in claim 8 further comprising a tensile spring, said spring being connected between said outer tube and said retractable inner rod and adapted to pull said retractable inner rod toward inside of said outer tube.
