Abstract: A supporting apparatus comprises a cover, a rotation seat, a supporting frame and a knob component. The rotation seat is configured in a inlaid part of the cover and disposed with a limit element capable of being let in a limit slot of the cover; the supporting frame is disposed with a positioning part capable of being let in an accepting part of the rotation seat to allow the supporting frame to be positioned on the rotation seat; the knob component is installed on the positioning part of the supporting frame, and rotated between a buckling position and a release position relatively to the supporting frame; the supporting frame is coupled to the rotation seat to support the cover when the knob component is rotated to the buckling position and an angle of the supporting frame at which the cover is supported can be adjusted by changing a position of the limit element in the limit slot.
