Multi-stage and multi-articulate support for a portable device

The present invention relates to a multi-stage and multi-articulate support for a portable device, which is made of multiple sections so that the user can freely adjust the direction, angle and length of the support and collapse the support as much as possible so as to readily carry it. When the adjustment is made of the angle and length of the support, there is no need to do a separate fixture, and the support is freely pivoted to different directions to be fixed at a position. The support comprises: a support (100) having a lower tube (110), middle tube (120), and upper tube (130), the diameters of the lower, middle and upper tubes being sequentially reduced, the support (100) being sequentially inserted in the inside of the lower tube (110); and a hinge structure fixed at the lower end of each of the lower, middle and upper tubes, the hinge structure consisting of a ball hinge (20) pivotably fixed and supported under the pressure of a spring, wherein each ball hinge (20) moves along the inside peripheries of the lower and middle tubes, and freely pivots when protruding from the upper ends of the lower and middle tubes.
