BACKGROUND OF THE INVENTION
 A conventional supporting frame includes four supporting rods and several plates for receiving goods thereon. The supporting frame has a rigid structure wherein each plate is firmly engaged its four ends with the four rods. The space between two plates is hard to be changed. Large goods cannot be placed therein. And it will be waste when only small goods are placed in a large fixed space.
 Accordingly, the present invention provides a supporting frame with adjustable connecting joints, which includes spiral rods and taped joints to provide an easy connection and adjustment effectively for overcoming the drawback of prior art.

DETAILED DESCRIPTION OF THE INVENTION
 Please referring to FIG. 1 to 3, the present invention relates to an improvement of a supporting frame, which includes four spiral rods (2) connecting with several supporting plates (3) for receiving or placing goods. The invention also provides a taped joint (1) being consisted of two half pieces (11), (12) by use of engagement of convex (111) on the first piece (11) and groove (121) on the second piece (12). The joint (1) has screwed inner surface (13) to match with the surface of the spiral rod (2). So the joint (1) can be rotated and moved upward or downward alone the rod (2).
 The supporting plate (3) is provided with a taped aperture (31) at its four ends. As the taped joint (1) is engaged within the taped aperture (31), it cannot be rotated or moved anymore. The connection therebetween is firm and secure and the supporting frame is utilized effectively.
 In use, the taped joint (3) can be adjusted at any desired position on the spiral rod (2) and then be connected with the plate (3). The space between any two plates (3) can be adjusted easily for receiving relating large or small goods. Other than the commercial use, it is a novel, practical and progressive structure design that absolutely well worth your attention and the patent grant. In actually application, an adjustable foot (4) can be connected with bottom end of each spiral rod (2) and a projection (21) is provided at lower end of each spiral rod (2) to prevent the lowest plate moved away from the rod.
