The planetary gear 5 meshed by the ring gear 6 is fixed on the frame 14. The number of teeth of the internal ring gear is twice that of the planetary gear. One end of the rack 7 is articulated with point C on the planetary gear 5. The other end of the gear meshes with a gear 8. The output shaft of gear 8 drives a set of steel rope transmission. In order to reduce the weight of the equipment and reduce the cost, the present invention design the ring gear to be smaller, so the stroke of the rack is much smaller than the stroke required for sucker rod pumping. To meet the needs of the pumping stroke, gear 8 and steel There is a stroke scaling device 9 between the rope transmission devices, which can cause a speed difference between the gear 8 and the steel rope transmission wheel 10, so as to achieve the scaling of the pumping stroke to meet the different needs of the oil.
