摘要： A tool includes a first member, a second member, a reinforcing device and a fastening assembly. The first member has at least one first working portion and a first pivoting portion. The second member has at least one second working portion and a second pivoting portion. The reinforcing device is arranged between the first member and the second member and configured to abut in surface contact against the first pivoting portion and the second pivoting portion. The fastening assembly inserts through the first pivoting portion, the second pivoting portion and the reinforcing device so that the first pivoting portion and the second pivoting portion are pivotally connected to each other.

摘要： A telescopic tool includes a positioning device mounted between first and second rods. The first rod includes a longitudinal hole extending along a longitudinal axis, a first positioning hole intercommunicating with the longitudinal hole, and a first gripping portion. The second rod is movably received in the longitudinal hole, includes a plurality of second positioning holes, and is movable relative to the first rod along the longitudinal axis to align the first positioning hole with one of the plurality of second positioning holes. A switch controller is movable relative to the first rod and is movably coupled to a positioning member. The positioning member movably extends through the first hole and is releasably engaged in one of the plurality of second positioning holes in response to movement of the switch controller relative to the first rod. A fixing member includes a second gripping portion mounted around the first rod.

摘要： A telescopic device includes a first shaft telescopically coupled to a second shaft. The first shaft defines a hole and an orifice. The second shaft defines a plurality of engaging portions. The second shaft inserts in the hole. The second shaft is movable with respect to the first shaft to a position in which one of the plurality of engaging portions is aligned with the orifice. A positioning device is coupled to the first and the second shafts. The positioning device includes a control being movable and a fastener being movable actuated by the control. The fastener is movable with respect to the control. The fastener inserts and is movable in the orifice. The first shaft is adapted to be unmovably positioned with respect to the second shaft at various positions by the positioning device.

摘要： A wrench has a first segment and a second segment pivotally coupled together. The second segment is selectively positionable at various fixed pivotal positions relative to the first segment. The first and the second segments engage with a locking device. The first segment has a first joining end forming a first positioning surface and a second positioning surface. The locking device includes a catch selectively engagable and disengagable from the first and the second positioning surfaces. The catch has a body section abutting against the first positioning surface in a direction radial to the axis of rotation when the first segment is at a first fixed pivotal position relative to the second segment. The first body section is abutted against the second positioning surface in a direction radial to the axis of rotation when the first segment is at a second fixed pivotal position relative to the second segment.
