Femoral condyle AP measurer

The invention relates to a femoral condyle AP measurer. The femoral condyle AP measurer comprises a measuring piece main body and a swinging component, wherein the swinging component comprises an adjustment base, a driving shaft, an eccentric wheel and a rotating shaft; the adjustment base and the measuring piece main body are hinged through the rotating shaft; a cam groove or a cam hole is formed in the adjustment base; the eccentric wheel rotates in the cam groove or the cam hole; the driving shaft is the eccentric shaft of the eccentric wheel and drives the adjustment base to swing around the rotating shaft relative to the measuring piece main body. According to the femoral condyle AP measurer, the eccentric wheel rotates to drive the adjustment base to swing around the rotating shaft, the swinging amplitude of the adjustment base is not the rotating amplitude of the driving shaft, and the rotating angle of the eccentric wheel can be set large; the eccentric wheel rotates to poke the adjustment base to swi
