description	The utility model relates to an easy disassembling support with adjustable length, belonging to the working jumbo module supporting technique. One end of the easy disassembling support is a screw pair structure which consists of a screw lever and a nut, or is a self locking wedge structure; the other end of the easy disassembling support has a guide frame, whose head connected to one end of a support bar is a cant structure; a metal wedge can wedge downward along the cant; a pin bolt is positioned at the upper part of the metal wedge and is connected to the guide frame; and wherein the lead angle of the metal wedge is larger than a critical self locking angle by 1 DEG to 3 DEG. The utility model utilizes a combination of a non self locking cant device and a screw pair or a self locking cant device, when in construction, the screw lever can be rotated or use the self locking metal wedge to wedge downward along the cant, thus the support structure forms a reliable support to the module and realizes tightly hold. After construction, the pin bolt can be hit out from the metal wedge and automatically withdraw from the cant, thus a whole lower support is in an unloading situation, thus the lower support can be easily removed.
