[0042] The connecting frame 31 is a supporting component of the assembly and is used to place other components;

[0043] A connecting ring 231 is movably sleeved at the connection between the rotating rod 23 and the connecting groove 22, and an oblique frame 26 is fixedly connected to the upper left of the connecting rod 21;

[0044] The connecting rod 21 is located above the pinion 14;

[0045] The connecting ring 231 can rotate in the connecting groove 22 and drive the rotating rod 23 to rotate. An inclined frame 26 is provided for placing cleaning components to clean the slot of the semicircular gear 13. The rotating rod 23 on the connecting rod 21 can drive the connecting brush 25 to clean the slot of the pinion gear 14.

[0046] A round rod 27 is fixedly connected to the transverse surface of the oblique frame 26, and a mounting brush 28 is fixedly connected to one side of the round rod 27;

[0047] The round rod 27 is used to place a mounting brush 28, and the mounting brush 28 can clean the slot of the semicircular gear 13;

[0048] A fixing rod 211 is placed at the connection between the connecting rod 21 and the frame 11. One end of the fixing rod 211 is fixedly connected to the frame 11, and the fixing rod 211 extends into the interior of the connecting rod 21. The fixing rod 211 has a mounting groove 212 at a corresponding position of the connecting rod 21.

[0050] The fixing rod 211 is used to connect the connecting rod 21 and the frame 11, and a mounting groove 212 is provided to facilitate the installation and removal of the connecting rod 21;

[0051] Working principle:

[0052] When the assembly is in normal use, the connecting rod 21 is connected to the fixed rod 211. When in use, the motor 16 is started, and the pinion 14 starts to rotate. At this time, the pinion 14 pushes the rotating rod 23 in the slot, so that the rotating rod 23 rotates through the connecting ring 231, so that the connecting brush 25 rotates and cleans in the slot of the pinion 14 to prevent debris from being in the slot.

[0053] When the pinion 14 rotates, the semicircular gear 13 meshing therewith rotates, so that the seat frame 15 below the semicircular gear 13 moves up and down, so that the height of the seat can be adjusted. When the semicircular gear 13 rotates, the right side of the semicircular gear 13 touches the installation brush 28, so that the installation brush 28 cleans the slot of the semicircular gear 13 to prevent debris from being in the slot.

[0054] When replacing a component, the connecting rod 21 is rotated by hand so that the connecting rod 21 is gradually rotated away from the fixing rod 211. When the fixing rod 211 leaves the installation groove 212, the component can be replaced;

[0055] In the above steps, the groove of the gear is cleaned through the interaction between the connecting brush 25 and the mounting brush 28 .

[0056] See also Figure 1-Figure 3 , Figure 6As shown, this embodiment is based on the above embodiment 1 and also includes:

[0057] Mobile components;

[0059] The slider 33 can slide in the slide groove 32 and drive the vertical rod 34 to move. The vertical rod 34 is used to connect other components.

[0060] A movable plate 35 is fixedly connected to the bottom end of the vertical rod 34, and the movable plate 35 is clamped with the connecting brush 25. The connecting frame 31 is located on one side of the connecting rod 21;

[0061] When the slider 33 drives the vertical rod 34 to move, it also drives the moving plate 35 to move, so as to move and clean the connecting brush 25 connected with the moving plate 35. The connecting frame 31 is located on the right side of the connecting rod 21.

[0062] The main assembly also includes a mounting rod 12 movably connected to one side of the frame 11, a semicircular gear 13 fixed to one end of the mounting rod 12, a seat frame 15 fixed below the semicircular gear 13, and a motor 16 fixed to the other side of the frame 11;

[0064] The mounting rod 12 is movably connected to the left end of the front side of the frame 11. The mounting rod 12 is used to place a semicircular gear 13. The semicircular gear 13 is used to mesh with a pinion 14. The semicircular gear 13 is fixed to the rear end of the mounting rod 12, thereby driving the seat frame 15 to move. The seat frame 15 is used to place the seat. The motor 16 is fixed to the rear side of the frame 11. The rear end of the pinion 14 is fixedly connected to the output end of the motor 16.

[0065] Working principle:

[0066] The chute 32 and the slider 33 are electrically connected to the motor 16. When the connecting brush 25 rotates to engage with the moving plate 35, the slider 33 moves in the chute 32, so that the slider 33 drives the vertical rod 34 to move, and the vertical rod 34 drives the moving plate 35 to move together. At this time, the moving plate 35 moves to the right side of the connecting brush 25 and breaks up the debris in the connecting brush 25, so that the debris in the connecting brush 25 falls to the outside, thereby realizing the cleaning of the connecting brush 25.
