Patent ID: 8881624

Claim:
A tool handle comprising: a first handle unit including a first handle body that has a first axis and a handle end surface oblique to the first axis, and an engaging block that protrudes from said handle end surface; a joint unit mounted rotatably around said engaging block and having an annular end surface that confronts said handle end surface and that surrounds said engaging block, and a plurality of spaced-apart and annularly-arranged positioning grooves formed in said annular end surface; a second handle unit including a second handle body that has a second axis, that defines a retaining space therein for retaining said joint unit, and that is co-rotatable with said joint unit; and a lock unit including a latch member that is inserted movably into said first handle unit, that has at least two spaced-apart latching projections projecting toward said annular end surface, and that is operable to switch between a lock state where said latching projections engage respectively at least two of said positioning grooves, and an unlock state where said latching projections are disengaged from the at least two of said positioning grooves; wherein, said first and second handle units are non-rotatable relative to each other when said latch member is at the lock state, and said second handle unit is rotatable about said engaging block to thereby adjust an orientation of said second handle unit relative to said first handle unit when said latch member is at the unlock state.
