As the jig for jangchimul dismantling of the invention, the stationary ring member is in the position pin parameters are fixed prevent rotation in jangchimul assembly, a rotating ring member having a knob to ride the outer circumferential surface of the fixing ring member smoothly rises helically jangchimul and a plurality for example increasing the horizontal rods member a fixing bolt connected to the medium and at the same time only can secure a small force easily dismantle jangchimul since the simple structure that automatically maintain the horizontal balance, but may significantly reduce the dismantling work, and jangchimul on the surface of the assembly only can be prevented from being generated flaws or scratches such as by collision with jangchimul from the insertion hole of jangchimul assembly can be generated is the center of gravity when the dissolution (breaking) in the upper heundeulrimyeonseo breakage occurs and that will be done to prevent depression symptoms from occurring.
