Feeder of automatic machine tool

The invention discloses a feeder of an automatic machine tool. The feeder structurally comprises a conveying mechanism, a controller and a base, the controller is installed at the front end of the base, and the conveying mechanism is fixedly embedded at the upper end of the base. Through extrusion generated by an iron rod-shaped material on an inner connecting ring on a stress plate, the inner connecting ring can downwards extrude boosting plates; the boosting plate at the upper end of an outer connecting ring swings downwards, so that a swinging plate swings under the cooperation of a friction increasing block to push the inner connecting ring to rotate, and rust in rust collecting grooves can be discharged when the rust collecting grooves rotate to the upper ends of the inner sides of the boosting plates; lower push plates which rotate to the upper ends of the inner sides of the boosting plates can be pushed downwards rapidly by elastic strips to stretch out downwards, so that most of the rust in the rust c
