1. A foldable and portable storage shelf, comprising: two spaced apart side frames;a panel assembly, which comprises three or more foldable shelf panels spacedly and pivotally supported between said two side frames, wherein each of said foldable shelf comprises two side panels pivotally coupled with each other at two inner edges thereof to define a pivot point and pivotally coupled with said side frames at outer edge of said side panels respectively;a foldable frame, which is operatively coupled with said side frames at a rear side of said panel assembly, comprising a transmission link pivotally coupled with said foldable shelf to pivotally fold said panel assembly between an unfolded position and a folded position, and two folding arms which are slidably coupled with said transmission link and pivotally coupled with said side frames respectively, wherein said transmission link is a vertical member and is coupled at said pivot points of said three or more foldable shelf panels at said rear side thereof at a position that an upper end of said transmission link is coupled at said pivot point of said foldable shelf panel at the uppermost position while a lower end of said transmission link is coupled at said pivot point of said foldable shelf panel at the lowermost position, wherein said foldable frame forms a rigid support for said panel assembly when said foldable shelf panels are moved at said unfolded position, wherein at said unfolded position, said transmission link is moved downwardly that said foldable shelf panels are rigidly supported between said side frames to form said shelf structure having a front opened side, and a left opened side and a right opened side, and at said folded position, said transmission link is moved upwardly to pivotally fold said foldable shelf panels in a concurrent manner to fold said side frames side-by-side so as to minimize a distance between said side frames, wherein a downward force of said foldable shelf panels is transmitted to said transmission link when said foldable shelf panels are folded at said unfolded position; andwherein said foldable frame further comprises a sliding joint slidably coupling with said transmission link and pivotally coupling with said folding arms, wherein said sliding joint is slid along said transmission link away from said upper end thereof when said foldable frame is folded at said folded position and is slid along said transmission link toward said upper end thereof when said foldable frame is folded at said unfolded position; and further comprising a shelf locker for releasably locking said foldable frame at said unfolded position, wherein said shelf locker comprises a first locker provided at said upper end of said transmission link and a second locker provided at said sliding joint to releasably engage with said first locker to lock up said sliding joint at said upper end of said transmission link; and wherein said foldable frame further comprises a retention stopper provided at said upper end of said transmission link to bias against said sliding joint when said sliding joint is slid at said upper end of said transmission link at said unfolded position so as to prevent any further upward sliding movement of said sliding joint; wherein said first locker is provided at said retention stopper such that said second locker is releasably engaged with said first locker when said sliding joint is slid to bias against said retention stopper. 2. The foldable and portable storage shelf, as recited in claim 1, further comprising a top retention panel, which is positioned above said foldable shelf panels, having a pivotal side edge pivotally coupled with one of said side frame and an opposed detachable side edge detachably coupled with another said side frame, wherein a distance between said pivotal side edge and said detachable side edge of said top retention panel matches with a distance between said two side frames when said panel assembly is folded at said unfolded position, wherein when said detachable side edge of said top retention panel is detached from said corresponding side frame, said transmission link is enable to move for folding said panel assembly to said folded position, and when said detachable side edge of said top retention panel is coupled at said corresponding side frame, said side frames are locked up to retain said panel assembly at said unfolded position, wherein said detachable side edge of said top retention panel is also coupled at said corresponding side frame to lock up the distance between said side frames. 3. The foldable and portable storage shelf, as recited in claim 1, wherein each of said side frames comprises a front supporting member and a rear supporting member, wherein said front and rear supporting members are spaced apart from each other and are disposed in a vertical manner, wherein said front supporting members of said side frame forms said front opened area therebetween, wherein said front and rear supporting members form said left and right opened areas therebetween. 4. The foldable and portable storage shelf, as recited in claim 2, wherein each of said side frames comprises a front supporting member and a rear supporting member, wherein said front and rear supporting members are spaced apart from each other and are disposed in a vertical manner, wherein said front supporting members of said side frame forms said front opened area therebetween, wherein said front and rear supporting members form said left and right opened areas therebetween. 5. The foldable and portable storage shelf, as recited in claim 3, wherein said folding arms are pivotally coupling with said rear supporting members of said side frames respectively, wherein each of said rear supporting members has a U-shaped cross sectional portion to define a receiving cavity, wherein when said foldable frame is folded side-by-side at said folded position, said foldable frame is enclosed within said receiving cavities of said rear supporting members. 6. The foldable and portable storage shelf, as recited in claim 4, wherein said folding arms are pivotally coupling with said rear supporting members of said side frames respectively, wherein each of said rear supporting members has a U-shaped cross sectional portion to define a receiving cavity, wherein when said foldable frame is folded side-by-side at said folded position, said foldable frame is enclosed within said receiving cavities of said rear supporting members. 7. The foldable and portable storage shelf, as recited in claim 1, wherein said transmission link is coupled at said pivot points of said three or more foldable shelf panels at said rear sides thereof, such that when said transmission link is moved downwardly that said inner edges of said side panels are downwardly folded in a concurrently manner, said side panels of each of said foldable shelf panels are aligned edge-to-edge to form a planar configuration, and when said transmission link is moved upwardly that said inner edges of said side panels are upwardly folded in a concurrently manner, said two side panels are overlapped with each other at said folded position to minimize said distance between said side frames. 8. The foldable and portable storage shelf, as recited in claim 6, wherein said transmission link is coupled at said pivot points of said three or more foldable shelf panels at said rear sides thereof, such that when said transmission link is moved downwardly that said inner edges of said side panels are downwardly folded in a concurrently manner, said side panels of each of said foldable shelf panels are aligned edge-to-edge to form a planar configuration, and when said transmission link is moved upwardly that said inner edges of said side panels are upwardly folded in a concurrently manner, said two side panels are overlapped with each other at said folded position to minimize said distance between said side frames. 9. The foldable and portable storage shelf, as recited in claim 8, wherein said top retention panels comprises two detachable couplers provided at said detachable side edge thereof, wherein said detachable couplers are detachably coupled at two upper ends of said front and rear supporting members of said corresponding side frame respectively to lock up the distance between said side frames.
