The method is as follows.

1. Place the plug-in resistor to be processed on the lower cutter, so that the resistor body is placed directly below the avoidance area; the resistor pins at both ends of the resistor body are placed on top of the front end of a pair of lower cutters. In the placement slot, the resistor pins at both ends of the resistor body respectively extend to the outside of the knife edge of the pair of lower cutters.

2. Move the upper cutter downward, and the cutting edges of a pair of upper cutters and a pair of lower cutters are staggered respectively to cut off the resistor pins that protrude to the outside of the pair of lower cutter edges. Realize manual bending of plug-in resistors at both ends.
