ABSTRACT:
A positioning device for a hand tool includes a handle having a first connecting portion formed a chamber defined therein, a positioning member movably received in the chamber, and a tool head pivotally connected to the first connecting portion. The first connecting portion has a threaded hole. A rotatable plate has a threaded shank extended therefrom. The threaded shank passes through the threaded hole and abuts against the positioning member. The positioning member rigidly engages with the tool head. When the threaded shank is moved away from the positioning member, the tool head is available to be pivotally adjusted at a desired angle.
