A resistor body is arranged on the inner wall of a potentiometer shell, an electric brush is installed on an electric brush base, a guide rod is installed in the potentiometer shell, the electric brush base is arranged on the guide rod in a sleeved mode, the electric brush base is connected with the first end of a driving rod, and an installation through hole is formed in the electric brush base.The section, close to the first end, of the drive rod is a drive rod small-diameter section with the outer diameter reduced, the drive rod small-diameter section is sleeved with the sleeve, the sleevepenetrates through the mounting through hole of the brush base, and the sleeve is sleeved with the compression spring. According to the utility model, the elastic connection structure between the driving rod and the electric brush base is finally realized by adding the sleeve and the pressure spring, so that the stable connection between the driving rod and the electric brush base is realized, the stability of output sign
