Abstract
A hand tool includes a first and a second handles, a rotating locking set, a fastening set, and a spring. The first and second handles include chamfered planes respectively. The rotating locking set includes a rotating block and a locking block. The fastening set includes a stud and a nut. The spring is mounted around the stud and elastically abuts against the rotating block. The first handle or the second handle drives the rotating block to disengage from the locking block when being pulled by an external force. The first handle and the rotating block rotate with respect to the second handle by the stud as the center point. The rotating block and the locking block are locked with each other after rotating a specific angle, so as to position the first handle and the second handle.
