An angle adjustable hand tool includes a driving head (40) pivotably connected to a handle (10) and a pawl (20) is received in the handle and removably engaged with the teeth (43) in the driving head. A button (30) is engaged with a hole (115) in the handle and perpendicularly communicates with the hole (114) in which the pawl is received. The button includes a recess (32) and a second contact surface (33) connects the recess. When the button is pushed, the pawl is located in the recess of the button so that the driving head can be pivoted relative to the handle. The driving head is set when the pawl is engaged with the teeth of the driving head.
