[0029] When in use, during the normal operation of the ball guide rail, by starting the drive motor 19, the output end of the drive motor 19 will drive the special-shaped plate 7 to rotate. When the special-shaped plate 7 contacts the inner groove 10, the special-shaped plate 7 will be embedded in the inner groove 10. As the special-shaped plate 7 rotates, the special-shaped plate 7 will continuously press against the inner wall of the inner groove 10, so that the stop rod 14 moves, so that the compression plate 24 moves in the oil storage chamber 21, so that the compression plate 24 squeezes the lubricating oil stored in the oil storage chamber 21, and sprays the lubricating oil from the nozzle 11 to the ball slide 4.
