ABSTRACT:
A tool-shifting device includes a disk having a groove defined therein and a ring member is rotatably mounted to a first side of the disk. A plurality of sockets are pivotally connected to the ring member and each have a part received in the groove. The disk has a cutout communicating with the groove and a carrier movably disposed to a second side thereof, the carrier having a protrusion movably retained in a curved recess of a board which is pivotally disposed to the second end of the disk and actuated by a hydraulic cylinder. The socket removed to the cutout will be engaged with the carrier which is then moved along the curved recess of the board which is pivoted by the hydraulic cylinder. The part of the socket engaged with the carrier is then moved upwardly about a position where the socket is pivotally connected to the ring member so that an orientation of a tool received in the socket is changed with respect to the ring member.
