MULTI-HEADED POWER TOOL AND FASTENING SYSTEM FOR SAME AND SYSTEMS FOR FASTENING HEADS THEREON

Abstract: a power tool includes a head interface coupled to a forward end of an output shaft and a tool head element for engagement on the head interface. the tool head element has a housing including an input shaft configured to removably couple with the output shaft and a collar comprising locking elements. each locking element is biased inwardly towards the input shaft by biasing elements. upon attachment of the tool head element to the head interface, the locking elements are aligned into a circumferential groove of the head interface and held by the biasing elements therein to engage the tool head element onto the head interface and establish a drive connection between the output shaft and input shaft. thus, when a motor and transmission assembly of the tool is operated, the input shaft rotates with the output shaft about the axis and thus drives the tool head element.
