摘要： An improved collapsible sectional rod for cleaning firearms is provided. The cleaning rod includes a plurality of hollow tubular elongated sections which are preferably metallic and of substantially equal lengths. Each section includes a tapered end and a socket end configured so as to selectively receive a corresponding tapered end of an adjacently disposed elongated section. The collapsible rod further includes an elongated tubular handle having an internal volume and a plurality of internal threads. Preferably, the handle has a knurled outer surface. The collapsible rod further includes an elongated tubular tensioner having a substantially hollow internal volume. The tensioner includes an end that is substantially slidably disposed within the internal volume of the tubular handle. This slidably disposed end includes a threaded portion that is capable of selectively engaging the internal threads of the tubular handle. The collapsible rod further includes a tension cable having first and second enlarged ends. The tension cable extends substantially through the elongated sections, handle, and tensioner thereby linking these various components of the collapsible rod together. By twisting the tensioner into engagement with the internal threads of the handle, the cable is drawn taut and the various elongated segments are aligned and secured in a substantially straight end-to-end arrangement thus forming the length of the cleaning rod. The endmost elongated section is preferably threaded so as to accommodate and selectively engage a gun barrel cleaning tool.
