Abstract: A pivotal driving tool includes a socket having a non-circular cavity formed by three or more planer side walls, and having an inner retaining ring. A mandrel includes a driving shank having a non-circular cross section for engaging into the socket, to allow the socket to be rotated by the mandrel. The mandrel includes a narrowed neck portion to allow the mandrel to be pivoted relative to the socket, and one or more flat surfaces to solidly anchor the driving shank to the socket. A magnetic member may be disposed in the mandrel, to act on and to pull the driving shank into the cavity of the socket. A barrel may be slidably engaged onto the socket, to engage onto and to be disengaged from the mandrel.

Abstract: A rotatable connector includes a mounting rod, and a rotatable mounting sleeve. The mounting rod has a plug, a shoulder and a concave neck portion. The plug is provided with a retractable positioning ball. The mounting sleeve has an inner wall formed with a receiving recess for rotatably receiving the plug. The receiving recess has a wall formed with a plurality of positioning grooves for locking and positioning the positioning ball. Thus, the rotatable connector can be operated linearly to have a torque output along its linear direction, and can be operated in an angular manner to have an angular torque output and to change its direction of operation.
