An auto-breaking machine adapted for breaking off a base band from terminals of an electrical connector, wherein the terminals are connected with a side edge of the base band, the auto-breaking machine comprising:

• a positioning assembly for positioning the electrical connector with the base band stretching behind the positioning assembly;
• a breaking assembly including a motor, an adjusting part connected with the motor, a drive member fastened to the adjusting part and having a front defined as a drive post, a support holder located in front of the motor, a slider vertically slidably mounted to a front face of the support holder, and a breaking part fastened on the slider, wherein the drive member is fastened to the adjusting part with an adjustable offset distance formed between axes of the drive post and the motor so as to be driven by the motor to turn around the axis of the motor, a window is opened in the slider and has a height corresponding to the diameter of the drive post, the drive post projects in front of the support holder and is inserted in the window of the slider to drive the slider to slide up and down by means of the turn thereof and further drive the breaking part to move up and down;
• and
• a feeding assembly connected with the positioning assembly for driving the positioning assembly to deliver the electrical connector towards the breaking assembly so as to make the base band be broken off from the terminals by the up-and-down movement of the breaking part of the breaking assembly.
