Support structure

A support structure for holding an electronic device, comprising:

• a base;
• a pair of stands connected to a side of the base to support the base, each of the pair of stands being rotatable around a first rotation axis;
• a top hinge connected to an opposite side of the base, the top hinge being rotatable around a second rotation axis which is perpendicular to the first rotation axis;
• and
• a pair of holding arms rotatably connected to the top hinge for holding the electronic device and adjusting a tilt angle of the electronic device held by the holding arms by a rotation of the top hinge and a height of the electronic device held by the holding arms by a rotation of the pair of stands;
• wherein the base defines a pair of connecting grooves correspondingly at two opposite ends of one side of the base for connecting the stands, each of the stands comprises a main part, a connecting end formed at one end of the main part, and a supporting part formed at an opposite end of the main part, the supporting part is bent from the main part, the base comprises a fixing plate rotatably connected to the top hinge and a connecting part rotatably connected to the pair of the stands, the fixing plate comprises a bottom board and a pair of side arms perpendicularly extending upward at two opposite sides of the bottom board, the pair of the side arms defines a receiving space therebetween, the top hinge assembled with the holding arms is placed in the receiving space and rotatably connected to the side arms, the top hinge comprises a case body having an opening at one side and an upper cover, the case body comprises a front plate, a back plate parallel to the front plate, and a pair of side plates correspondingly connected to opposite sides of both the front plate and the back plate, each of the holding arms is rotatably engaged on the front plate and the back plate, the upper cover comprises a cover plate and a plurality of clipping protrusions extending out from the cover plate, the upper cover covers on the opening of the case body, the clipping protrusions are inserted into the case body and define a gap between every two immediately adjacent clipping protrusions, and each of the holding arms is clipped in a respective gap of the clipping protrusions.
