The invention provides a point switch machine. The point switch machine comprises an actuating rod and a planetary gear mechanism, the planetary gear mechanism comprises a large gear ring which is provided with an outer gear ring and an inner gear ring, a planetary gear is meshed with the inner gear ring, a shaft of the planetary gear is in pivot joint with one end of a swinging arm, the other end of the swinging arm is in pivot joint with a driving shaft, and the driving shaft is connected with the actuating rod. According to the point switch machine, the bearing capacity of the point switch machine is improved by means of the gear mechanism, moreover, all circumference of the gear mechanism is kinematic pairs so that local abrasion is reduced, the service life of the point switch machine is prolonged, meanwhile, harmful impact during starting ad stopping of the point switch machine can be reduced, and the proven gear transmission technology is applied so that machining costs are lowered.
