摘要： A driving head-changeable tool is provided, including a tool set and a driving head. The tool set includes a connecting sleeve, an outer sleeve and at least one limitation member. The connecting sleeve has a receiving slot and a driving end. A plurality of protruding ribs extending axially and a plurality of recesses disposed between the protruding ribs are disposed on an inner wall of the receiving slot. The recesses are provided for a polygonal ball head to insert therein. A recessed portion and a protruding portion are disposed on the inner wall. The outer sleeve is slidable between a first position and a second position. When the outer sleeve is at the first position, the limitation member can restrict the polygonal ball head. When the outer sleeve is at the second position, the polygonal ball head is withdrawable from the receiving slot.

摘要： A tool joint is provided, including a main body, a swingable member and a locking structure. The main body has a connecting channel. The swingable member is disposed on the main body. A driving rod is disposed through the swingable member and movable between a first position and a second position. When the driving rod is in the first position, the driving rod is out of the connecting channel, the swingable member is swingable relative to the main body. When the driving rod is in the second position, the driving rod projects within the connecting channel and the swingable member is non-swingable relative to the main body.

摘要： A driving head-changeable tool is provided. An outer sleeve defines a central axis and has an end peripheral edge which has corner portions and blocking flanges therebetween and a circumferential sliding slot. An inner sleeve is rotatably sleeved by the outer sleeve and has opposite first and second connecting ends. An inner wall of the first connecting end has axial concaves. A limitation mechanism is mounted to the inner sleeve and extends into and movable relative to the sliding slot. When the limitation mechanism is located in a lock position, the outer and inner sleeves are unrotatable relative to each other and each concave overlaps axially with one of the blocking flanges; when the limitation mechanism is located in a release position, the outer and inner sleeves are rotatable relative to each other and each concave corresponds to one of the corner portions.
