Abstract
A foldable hand tool includes a handle having a hole laterally defined in a font end of the handle for pivotally connecting to a working element. The working element has a pivotal end pivotally received in the front end and a polygonal hole which is centrally defined in the pivotal end. A groove is radially defined in the pivotal end and communicates with the polygonal hole. A locking element is reciprocally movably mounted in the hole in the handle for selectively positioning the working element.

A foldable hand tool comprising:
- a handle having a hole laterally defined in a font end of the handle for pivotally connecting to a working element;
- the working element having a pivotal end pivotally received in the front end of the handle and a polygonal hole centrally defined in the pivotal end, the polygonal hole longitudinally communicating with the hole in the handle when the pivotal end received in the front end of the handle, a groove radially defined in the pivotal end and communicating with the polygonal hole;
- and
- a locking element reciprocally movably mounted in the hole of the handle for selectively positioning the working element, wherein the locking element is limited to prevent the locking element from being rotated relative to the handle.
