The threaded block drives the rotating ring to reciprocate, and the rotating ring drives the connecting frame to reciprocate. The connecting frame drives the square shell to lift, the square shell drives the sliding plate to lift, the sliding plate drives the cross bar to lift, and the cross bar drives the special-shaped shell to lift. The special-shaped shell will be tightly fitted and blocked with the inner wall of the gear ring during the lifting process, further preventing the planetary gear from reversing.

[0017] (2) In the present invention, three notches are set on the top of the fixed plate, and the fixed plate is connected to the top of the connecting frame. During the rotation of the fixed plate, the connecting frame is driven to rotate, and the connecting frame drives the rotating ring to rotate. Because the rotating ring is rotatably connected to the outer wall of the threaded block, it can prevent the rotating ring from getting stuck during the movement. When the connecting frame rotates, the side wall of the special-shaped shell and the side wall of the gear ring are brought into contact. Due to the protrusions of the special-shaped shell and the gear ring, the two are squeezed against each other, so that the special-shaped shell drives the cross bar to move toward the square shell, and the cross bar drives the sliding plate to move toward the inside of the square shell. During the movement of the sliding plate, the lubricating liquid inside the square shell is squeezed, and the lubricating liquid enters the inside of the elastic tube, and the lubricating liquid enters the inside of the special-shaped shell through the elastic tube. Through the setting of the special-shaped hole, the lubricating liquid enters the special-shaped shell and is sprayed toward the outer wall of the gear ring through the special-shaped hole, thereby spraying the inner wall of the gear ring, improving the running stability of the gear ring, and improving the self-locking stability from the side.

[0018] (3) According to the present invention, when the square shell is lifted or lowered, the square shell drives the slider to lift or lower, the slider drives the movable frame to lift or lower, the movable frame drives the second flexible cleaning cotton to lift or lower, and the second flexible cleaning cotton will apply the lubricating liquid attached to the surface of the gear ring during the lifting or lowering process, thereby improving the lubricating effect of the lubricating liquid on the gear ring; when the sliding plate moves toward the inside of the square shell, the sliding plate drives the first rotating bar to move, the first rotating bar drives the lifting rod to move vertically upward along the inner wall of the square shell, the lifting rod drives the second rotating bar to move upward, the second rotating bar drives the slider to move horizontally along the top of the inner wall of the square shell, the slider drives the movable frame to move, the movable frame drives the second flexible cleaning cotton to approach the gear ring, so that the second flexible cleaning cotton further fits the inner wall of the gear ring, thereby improving the lubricating effect of the lubricating liquid on the gear ring.

[0019] (4) In the present invention, when the connecting frame rotates, the connecting frame drives the sliding frame to rotate, the sliding frame drives the bending rod to rotate, and the bending rod drives the receiving shell to rotate. The reset spring is set so that the receiving shell continuously contacts the bottom of the gear ring to receive the dripping lubricating liquid. At the same time, when the special-shaped shell descends, the special-shaped shell drives the vertical rod to descend, and the vertical rod drives the first flexible cleaning cotton to descend. During the descent process, the first flexible cleaning cotton will move to the inside of the receiving shell to absorb the lubricating liquid stored in the receiving shell. When the special-shaped shell moves up, the special-shaped shell drives the first flexible cleaning cotton to move up. During the upward movement of the first flexible cleaning cotton, the side wall of the gear ring can be coated again, thereby preventing excessive consumption of the lubricating fluid and improving the lubricating effect of the lubricating fluid on the gear ring. When the sliding plate moves toward the inside of the square shell, the sliding plate drives the extrusion frame to move, and the extrusion frame moves inside the fixed shell. Affected by the setting of the condensation plate, the condensation plate cools the airflow inside the fixed shell. During the movement of the extrusion frame, cold air enters the inside of the bent pipe, and the cold airflow enters the inside of the exhaust shell through the bent pipe. The cold airflow passes through the exhaust shell to cool the lubricating fluid at the gear ring and sprays it, thereby improving the lubricating effect of the lubricating fluid on the gear ring.

When the sliding plate 564 moves toward the inside of the square shell 563, the sliding plate 564 drives the first rotating bar 581 to move, and the first The rotating bar 581 drives the lifting rod 582 to move vertically upward along the inner wall of the square shell 563, the lifting rod 582 drives the second rotating bar 583 to move upward, the second rotating bar 583 drives the slider 584 to move horizontally along the top of the inner wall of the square shell 563, the slider 584 drives the moving frame 585 to move, and the moving frame 585 drives the second flexible cleaning cotton 586 to approach the gear ring 3, so that the second flexible cleaning cotton 586 further fits the inner wall of the gear ring 3, thereby improving the lubricating effect of the lubricating liquid on the gear ring 3.

[0046] When the connecting frame 562 rotates, the connecting frame 562 drives the sliding frame 571 to rotate, the sliding frame 571 drives the bending rod 573 to rotate, and the bending rod 573 drives the receiving shell 574 to rotate. The reset spring 572 is set to make the receiving shell 574 continuously contact the bottom of the gear ring 3 to receive the dripping lubricating liquid. At the same time, when the special-shaped shell 566 descends, the special-shaped shell 566 will drive the vertical rod 575 to descend, and the vertical rod 575 drives the first flexible cleaning cotton 576 to descend. The first flexible cleaning cotton 576 will move to the inside of the receiving shell 574 during the descent process to absorb the lubricating liquid stored in the receiving shell 574. When the special-shaped shell 566 moves up, the special-shaped shell 566 drives the first flexible cleaning cotton 576 to move up. During the upward movement of the first flexible cleaning cotton 576, the side wall of the gear ring 3 can be coated again, thereby preventing excessive consumption of the lubricating fluid and improving the lubricating effect of the lubricating fluid on the gear ring 3. When the sliding plate 564 moves toward the inside of the square shell 563, the sliding plate 564 drives the extrusion frame 587 to move, and the extrusion frame 587 moves inside the fixed shell 588. Affected by the setting of the condensation plate 589, the condensation plate 589 cools the airflow inside the fixed shell 588. During the movement of the extrusion frame 587, cold air enters the inside of the bent pipe 5810, and the cold airflow enters the inside of the exhaust shell 5811 through the bent pipe 5810. The cold airflow passes through the exhaust shell 5811 to cool down the lubricating fluid at the gear ring 3 and sprays it, thereby improving the lubricating effect of the lubricating fluid on the gear ring 3.
