A hand tool includes a tool head and a handle connected to the tool head. The tool head is adapted to drive a fastening member. The handle includes an external tube adapted to be held by a user, and an internal rod inserted into the external tube. One end of the internal rod is connected to the tool head. The external tube can be selectively moved relative to the internal rod between a first position and a second position. While in the first position, the external tube is securely engaged with the internal rod. While in the second position, the external tube is rotatable relative to the internal rod so that the user can regulate the external tube of the handle in the first position or the second position upon demands, thereby obtaining comfortable and power-saving operation. |
