A riveting electric tool for self-drilling and automatic drawing is provided to reduce operating process and time substantially and reduce the labor cost by completing a riveting operation by removing the rivet core after adhering at least two metal sheets by expanding an expansion cylinder while drawing out a rivet core using a chuck. A riveting electric tool for self-drilling and automatic drawing comprises: a forwardly and reversely rotating motor(11) rotated in a forward direction or a reverse direction; a clutch bearing(22) which is rotated together with the forwardly and reversely rotating motor when the forwardly and reversely rotating motor is rotated in the forward direction, and which is idled to transmit a forward rotary power of the forwardly and reversely rotating motor to the rotary cylinder when the forwardly and reversely rotating motor is rotated in the reverse direction, and which is idled to cutoff the rotary power when the forwardly and reversely rotating motor is reversely rotated; a rotary cylinder(23) for receiving the rotary power of the forwardly and reversely rotating motor through the clutch bearing to rotate a blind rivet fixed to a nozzle(41) in front of the rotary cylinder; a pair of a rack gear(24) and a pinion gear(19) for transmitting the rotary power of the forwardly and reversely rotating motor to the moving body in a sliding guide cylindrical body(25); a moving body(30) which is moved forward and backward in sliding spaces(28,29) of the sliding guide cylindrical body by receiving kinetic energy converted into reciprocation energy through the rack gear and the pinion gear, and which cuts and removes the rivet core from a rivet body of the blind rivet by allowing a drawing chuck(31) to grip and pull a rivet core of a blind rivet fixedly inserted into at least two metal sheets when the moving body moves backward; and a pistol-shaped case(10) in which the above components are embedded. |
