  • Patent number: 9440340
    Abstract: An electric rivet nut tool has a motor, a torque adjuster and a control device. The control device drives the motor to rotate a driving shaft so as to set a rivet nut. The torque adjuster serves to adjust a preset torque value. When a torque generated by the driving shaft exceeds the preset torque value of the torque adjuster and it represents that the rivet nut setting job is completed, the torque adjuster then displace for the control device to detect the displacement and drive the motor to reversely rotate. Given the torque adjuster and the control device, the problems of being time-consuming, inefficient, increasing in cost and damage prone to rivet nut or motor upon setting rivet nut because of the manual switch of forward or reverse rotation of an electric rivet nut tool can be effectively resolved.
