Abstract
A machine tool device capable of preventing hair from being sucked in is provided with a hair sucking preventing device. The hair sucking preventing device comprises an axial flow fan, a wind power sensor, a movable pedal and a controller. When an operator stands on the movable pedal to operate a machine tool, the controller controls the axial flow fan to work, a protection wind curtain is formed around a rotation chuck, and the hair, close to the rotation chuck, of the operator is blown up by the protection wind curtain so as to prevent the hair from being sucked in. If the axial flow fan fails, the protection air curtain disappears, the wind power sensor transmits the corresponding signal to the controller, the controller cuts off the power of a machine tool control circuit, the rotation chuck cannot rotate, and machine tool safety accidents are prevented or reduced.
