A rivet nut electric tool comprises an outer cover (37), a clutch control system, a gear transmission system, a stroke control system and a screw-rod nut assembly. The clutch control system, the gear transmission system, the stroke control system and the screw-rod nut assembly are arranged in the outer cover (37). The clutch control system is cooperated with the gear transmission system to be on and off and transmit. The stroke control system precisely controls the stroke. Signals can be provided and the nut is riveted by the moving of a screw-rod (7). The gear clutch assembly drives a hexagonal connecting rod (6) to finish rivet nut screwing-in and screwing-out. Three sensors (39) are connected with a circuit board (25) by control wires. The clutch control system is cooperated with the three sensors (39) to work. A trigger (34) is arranged on the outer cover (37). The rivet nut electric tool with the structures has the advantages of that the power is high and rivet nuts with different specifications can be riveted. The circuit board controls precisely the clutch control system, the gear transmission system and the stroke control system to make sure that the rivet nuts are reliably installed in place to be riveted. Further more, the stroke and the electric quantity are visible, and the operation is convenient. |
