The present invention provides an adjustable backing plate structure, including a main backing plate, being defined into a plate surface and a bottom surface. A connecting rack includes a locating end and swinging end. The locating end is adapted to the main backing plate, and the swinging end extends to a predefined length. A supporting member is coupled with the swinging end of the connecting rack for synchronous displacement with the swinging end and is placed either underneath or laterally on the bottom surface of the main backing plate. The adjustable backing plate structure can be placed on any support, such as a table surface or two legs, the horizontal level or tilt angle with the displacement of the supporting member being adjusted to realize the benefit of desired ease-of-operation with improved applicability.
