Supporting apparatus

A supporting apparatus, comprising:

• a cover, comprising a inlaid part and at least one limit slot, the limit slot being positioned on a bottom of the inlaid part;
• a rotation seat, configured in the inlaid part and comprising a limit element, an accepting part, at least one breach and at least one fastening part, the limit element used for letting in the limit slot and moving in the limit slot, the fastening part being position at a rim of the breach;
• a knob component, comprising at least one propping part and a groove;
• and
• a supporting frame, comprising a positioning part and at least one opening, the positioning part allowing the propping part of the knob component to be placed therein and used for letting in the accepting part to cause the supporting frame to be positioned on the rotation seat, the opening being positioned at a rim of the positioning part, and the knob component being rotated between a coupling position and a release position relatively to the supporting frame, when the knob component is rotated to the coupling position, the propping part being passed through the opening and breach to prop against the fastening part to enable the supporting frame to be coupled to the rotation seat to support the cover;
• whereby, an angle of the supporting part at which the supporting frame is supported is adjusted by changing a position of the limit element in the limit slot.
