A tool holder for holding a cutting tool comprises a housing, a sleeve received in one end of the housing, a switch fastened in the other end of the housing, a cover fastened at an end of the housing adjacent to the sleeve to prevent the sleeve from being taken out of the housing, and an elastic member sleeved on the sleeve. The switch is electrically connected to a control system of a main spindle of a CNC turning machine and is applied for controlling the movement of the main spindle. The elastic member is compressed to elastically resist with the sleeve and generates an elastic force to make the sleeve move away from the switch, and the sleeve is slidably configured along the inner surface of the housing to contact the switch to stop the movement of the main spindle of the CNC turning machine.
