The cloth pricking stroke adjusting device comprises a driving mechanism, and an output shaft of the driving mechanism rotates to drive a presser foot lifting cam and an adjusting crank to rotate to a working position; the working positions comprise at least one adjusting position of the presser foot lifting cam and at least one adjusting position of the adjusting crank; the adjusting position of the presser foot lifting cam corresponds to the upper limit position and the lower limit position of the foot lifting module; the adjusting crank is hinged to the adjusting connecting rod, the adjusting position of the adjusting crank corresponds to the target angle of the adjusting crank, and the driving mechanism drives the adjusting crank to swing to the target angle, so that the position of the fixed end of the adjusting connecting rod changes along with the target angle of the adjusting crank. By adjusting the position target of the fixed end of the connecting rod, the target cloth puncturing stroke is correspondingly adjusted, the cloth puncturing stroke adjusting device is applied to the sewing machine, and the sewing machine with the cloth puncturing stroke adjusting function is obtained.
