Clamp electrode capable of reducing contact resistance during resistance measurement

The invention discloses a clamp electrode capable of reducing contact resistance during resistance measurement, and belongs to the technical field of clamp electrodes, the clamp electrode comprises an upper clamping arm, a middle-layer arm and a lower clamping arm, the middle-layer arm is arranged on the lower clamping arm, the middle-layer arm and the lower clamping arm are rotatably connected through a rotating shaft, and the outer side of the rotating shaft is sleeved with a torsion spring. According to the invention, by arranging the position adjusting mechanism, the upper clamping arm can move up and down along the threaded column, so that the distance between the upper clamping arm and the lower clamping arm can be controlled, and the surfaces of upper and lower clamping teeth and the surfaces of plates with different thicknesses and different included angles between the upper and lower surfaces can be perfectly fitted by matching with the plates for testing; under the condition that the surface is unev
