[0002] Alloy resistors are resistors that use alloys as current media. They are often used to sample current in circuits and to provide feedback on changing currents in circuits in order to further control or influence current changes. Existing stamping and cutting dies for alloy resistors have poor stamping and cutting effects, which can easily cause large fluctuations in resistance values. The spacing between the cutting knives is difficult to adjust and cannot meet different cutting requirements.

By setting a clamping and fixing mechanism, the clamping and fixing mechanism can clamp and fix the cutting knife, which is convenient for disassembly and replacement of the cutting knife. Loosening the first locking knob and moving the slide plate left and right can adjust the distance between the clamping and fixing mechanisms, and then the distance between the cutting knives can be adjusted. The alloy resistors can be cut into different lengths according to needs, and the cutting efficiency is improved. However, the stamping and cutting die for alloy resistors has the following shortcomings: the sharpness of the cutting knife will decrease after a period of use, and some debris adhesion will also affect the use of the cutting knife.
