Support frame structure for electronic device

A support frame structure for electronic device used for mounting an electronic device, comprising:

• a stationary rod body being a columnar rod body having uniform cross section, the bottom of stationary rod body being disposed with an attaching member for the stationary rod body to be fastened to an object;
• a mounting rod body being a rod body and consisting of a mounting member and a sleeving member, the mounting member being disposed at one end of the mounting rod body for mounting the electronic device, the sleeving member being disposed at the other end of the mounting rod body and having a perforated hole being vertically perforating the mounting rod body in axial direction;
• and
• an extending rod body having an extending rod pivot joint member at one end and an extending rod sleeving member at the other end, the extending rod pivot joint member being a columnar rod body with uniform cross section and perpendicular to the axial direction of the extending rod body, the extending rod sleeving member being disposed with an extending rod perforated hole vertically perforating the extending rod body in axial direction, the side wall of the extending rod perforated hole being levelly disposed with an adjusting bolt;
• wherein the inner diameter of the perforated hole of mounting rod body matches the outer diameter of the extending rod pivot joint member;
• the inner diameter of the extending rod perforated hole matches the outer diameter of the stationary rod body;
• the perforated hole of the sleeving member of mounting rod body sleeves over the extending rod pivot joint member, and the perforated hole of the extending rod sleeving member sleeves over the stationary rod body.

The support frame structure according to 22, wherein the extending rod pivot joint member of the extending rod body further comprises:

• a hollow member extending therein axially through the top, the inner surface of hollow member being disposed with an annular body, the annular body being formed by extending radially from the inner surface of hollow member and having an inner hole, a plurality of guide grooves, and a plurality of notches, the inner hole perforating axially the center of annular body, the guide grooves being inwardly concave structures indenting from the inner surface of inner hole and extending along the axial direction, the notches being inwardly concave structure at the bottom surface of annular body 311a that extend from the inner surface of inner hole 311b along the radial direction;
• a cap body consisting of an outer cap member and a columnar member, the outer cap member being a dish-shaped body with outer diameter being greater than the inner diameter of perforated hole disposed on the sleeving member of mounting rod body, the columnar member being a cylindrical body extending axially from the bottom surface of outer cap member and slightly longer than the inner hole, a plurality of flanges being configured at the bottom of columnar member formed by extending radially and outwardly from the outer surface of columnar member;
• and
• an elastic member disposed inside the hollow member, one end of the elastic element being able to contact the bottom of the columnar member of cap body so as to provide an acting force to maintain the upward tendency of the cap body;
• wherein the outer cap member of cap body is disposed at the apex of hollow member, the columnar member of cap body is penetratively disposed in the inner hole of hollow member, the flanges correspond to the guide grooves and notches, and the respective flange may elect to simultaneously correspond to a guide groove or simultaneously correspond to a notch through the turning of the columnar member relative to the inner hole.
