Supporting devices for small and portable X-ray devices are described. In particular, this application describes supporting devices for portable X-ray devices containing a movable base unit with multiple legs with different lengths and heights configured so that the legs have a nestable configuration, an adjustable member extending from the mobile base unit so the adjustable member has an adjustable height, an extension arm connected to the adjustable member so the extension arm collapses toward and extends away from the adjustable member, and a connecting member connecting the extension arm with a portable x-ray device so the connecting member can rotate up to 360 degrees in the x, y, or z direction. The connecting member can also connect the extension arm with a portable x-ray device so the portable x-ray device is removable from the connecting member and capable of being operated independently by hand. Other embodiments are described.
