         [0003]    2. Description of the Prior Art 
         [0004]    As for the conventional common daily necessities, such as clothes rack, bookshelf, basketball backstop, clothes horse, horizontal bar, lamp support, flower shelf and so on, no matter how the structure is designed, each must have a support rod used to support a specific object. However, the support rods for various specific objects vary in structure design due to the limitation of the structures and the functions of the various specific objects, in other words, the function of the respective support rods is nearly the same, but the support rods are not interchangeable, and it is necessary to develop a support rod of different structure for every object. Thereby, developing various structures with almost the same functions increases the manufacturing cost, which is uneconomical and limited in practical use, and some of the manufactured support rods are quite difficult to operate or assemble, and some occupy much space after being assembled. 
         [0005]    The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

Thereby, no matter how large the space is, the present invention is quite suitable for assembling with the objects at any place for use. 
         [0008]    Hence, an adjustable multi-function support assembly in accordance with the present invention comprises an extension mechanism, at least one positioning device, a first abutting mechanism and a second abutting mechanism. 
         [0009]    The extension mechanism includes a plurality of tubes that are axially pivotally coupled with each other, between tubes is disposed an assistant sleeve for assisting an axial extension of the respective tubes, and each end of the extension mechanism includes a connecting portion. 
         [0010]    The positioning device is inserted into the first tube, the assistant sleeve and the second tube. 
         [0011]    One end of the first abutting mechanism is assembled to the connecting portion of one end of the extension mechanism, and the other end of the abutting mechanism includes an anti-slip for abutting against a predetermined position. 
         [0012]    One end of the second abutting mechanism is assembled to connecting portion of the other end of the extension mechanism, and the other end of the abutting mechanism includes an anti-slip block for abutting against a predetermined position.
