ABSTRACT:
A power tool for the setting of blind rivets has a reversible electric motor which can reciprocate a gripper for the mandrel of a blind rivet through a transmission employing a rotary nut driven by the motor and a spindle which reciprocates the gripper in response to rotation of the nut. The motor is permanently connected with the spindle, and hence with the gripper, and the ratio of the transmission including the nut and the spindle is not dependent upon the position of the gripper. Such construction enhances the comfort to the operator of the power tool. The electric circuit for the motor is designed in such a way that the motor is disconnected from a portable energy source and is braked prior to a reversal in the direction of rotation of its output element.
