Supporting apparatus

A supporting apparatus for supporting an electronic device, wherein the electronic device comprises a bottom surface and a first lateral surface, the supporting apparatus comprising:

• a base, comprising a front end and a rear end;
• a device supporting portion, comprising:
• a supporting element;
• and
• a first rotating shaft, pivotally connected to the rear end of the base and connected with the supporting element for allowing the supporting element to rotate along the first rotating shaft, such that the supporting apparatus has a closed state and a first open state;
• a device connecting portion, comprising:
• a connecting element configured to be matched with a built-in connector of the electronic device;
• a second rotating shaft, pivotally connected to the front end of the base and the connecting element located on the second rotating shaft;
• and
• two torsion springs, respectively wrapped at the two ends of the second rotating shaft;
• and
• a linking rod, comprising:
• a first end, pivotally connected to the first rotating shaft;
• and
• a second end, pivotally connected to the second rotating shaft;
• wherein, when the supporting apparatus is in the closed state, the supporting element and the linking rod formed a supporting element folding angle θ1, wherein 0°≦θ1≦35°;
• meanwhile, the connecting element and the linking rod formed a connecting element folding angle θ2 wherein 0°≦θ2≦75°;
• when the supporting apparatus rotates from the closed state to the first open state, the supporting element and the linking rod form a first supporting element opening angle θ11, wherein 35°≦θ11≦90°;
• the connecting element and the linking rod form a first connecting element opening angle θ21, wherein θ21>θ2 for allowing the connecting element to connect with the first lateral surface of the electronic device and the supporting element to contact the bottom surface.
