The movement of the planetary gear 3 is output through the planet carrier, so as to realize the speed reduction function. When the planetary gear 3 moves, the extrusion block 5 moves. When the extrusion block 5 moves and passes through the inclined block 6, the extrusion block 5 extrudes the inclined block 6 to move, thereby extruding the tension spring 7 to drive the push column 8 to slide on the inner wall of the air cylinder 9, thereby driving the piston 12 to slide on the inner wall of the air cylinder 9, so as to compress the gas in the air cylinder 9 to be discharged to the oil tank 10 at the air outlet pipe 14. Since the upper part of the oil tank 10 is sealed by the extrusion plate 15, the gas increases, so the pressure increases, thereby compressing the extrusion plate 15 to slide on the inner wall of the oil tank 10. Since the oil outlet pipe 11 is located above the meshing position of the planetary gear 3 and the ring gear 2, the lubricating oil is extruded to be discharged to the meshing position of the planetary gear 3 and the ring gear 2 at the oil outlet pipe 11, so as to realize the automatic oiling of the speed reduction mechanism.
