A driving tool includes a driving shaft and a bar which movably extends through the driving shaft. At least one of two end sections of the bar has a hole and a recess, wherein an engaging member is engaged with the hole and protrudes out from outer surface of the bar. The recess is defined axially in the end of the at least one end section and a control rod and a resilient member are received in the recess. The control rod includes a first notch and a second notch of different depths. When the control rod is operated to overcome a force of the resilient, the engaging member is engaged with the second notch, the engaging member is retracted into the at least one end section. The bar can be separated from the driving shaft so as to change the driving shaft.
