[0016] Example:

[0017] like Figure 1 As shown, an armrest includes a main body, which is composed of a first bending section 24 and a second bending section 11 connected to each other. A supporting plate 21 is provided at the top of the first bending section 24, and a first sliding groove 10 and a second sliding groove 34 are provided in the second bending section 11. The first sliding groove 10 is connected to the second sliding groove 34. An extension plate 27 is provided in the first sliding groove 10 for sliding along the length direction. The main body is fixed to the seat through the extension plate 27, and the distance between the main body and the seat can be adjusted by the position of the extension plate 27 in the first sliding groove 10. The distance between the main body and the seat can be adjusted to meet the usage needs of different users.

[0018] When the distance between the main body and the seat needs to be adjusted, the extension plate 27 is slid to adjust the position in the first sliding groove 10. After the adjustment is completed, the extension plate 27 is fixed relative to the second bending section 11. After the fixing is completed, the extension plate 27 is fixed to the seat.

[0019] A first placement groove 12 is provided in the first bending section 24, and a first force-bearing rod 23 is provided in the first placement groove 12 for sliding along the length direction. The relying plate 21 is rotatably arranged at the top end of the first force-bearing rod 23, and the relying plate 21 can rotate relative to the first bending section 24, which can meet the use requirements in various directions.

[0020] A second placement slot 16 is provided in the first force-bearing rod 23, and the second placement slot 16 is connected to the outside and has a first limiting hole 14. A plurality of second limiting holes 15 are provided through the inner wall of one side of the first placement slot 12. Figure 1As shown, in this embodiment, there are five second limiting holes 15, a limiting rod 13 is passed through one of the second limiting holes 15 and the first limiting hole 14, a limiting plate 26 is fixedly provided on the inner wall of the second placement groove 16, an elastic member 25 is clamped in the limiting plate 26, the limiting rod 13 is fixedly connected to one end of the elastic member 25, the elastic member 25 can undergo elastic deformation, and can still recover when subjected to a certain degree of external force.

[0021] A first connecting shaft 17 is fixedly provided at one end of the first force-bearing rod 23, and the first connecting shaft 17 extends into the third placement cavity 19. A second connecting shaft 20 is fixedly provided at the end of the first connecting shaft 17, and the second connecting shaft 20 is rotatably connected to the supporting plate 21. A plurality of first limiting teeth 18 are fixedly provided on the outer periphery of the first connecting shaft 17, and a third placement cavity 19 is opened at one end of the supporting plate 21. A plurality of second limiting teeth 22 are evenly fixed on the inner wall of the third placement cavity 19 along the circumference, and the first limiting teeth 18 abut against the second limiting teeth 22, and the first limiting teeth 18 cooperate with the second limiting teeth 22, so that the supporting plate 21 can adjust the gear position.

[0022] like Figure 1 and Figure 2 As shown, a third sliding groove 29, a fourth sliding groove 31 and a fifth sliding groove 33 are provided in the extension plate 27. The third sliding groove 29, the fourth sliding groove 31 and the fifth sliding groove 33 are connected. The first screw 28 with a nut passes through the fifth sliding groove 33, the fourth sliding groove 31 and the third sliding groove 29 in sequence and is threadedly connected to the seat. The nut diameter of the first screw 28 is greater than the width of the fifth sliding groove 33.

[0023] One end of the second screw 30 with a nut passes through the third sliding groove 29, the fourth sliding groove 31 and the fifth sliding groove 33 in sequence and is threadedly connected with a nut 32. The diameter of the nut of the second screw 30 is larger than the width of the third sliding groove 29, and the diameter of the nut 32 is larger than the width of the fifth sliding groove 33.

[0024] The positions of the first screw rod 28 and the second screw rod 30 can be adjusted according to actual conditions. According to the different positions of the extension plate 27 in the first sliding groove 10, the positional relationship between the first screw rod 28 and the second screw rod 30 will also change accordingly.

[0025] Working principle:

[0026] When the distance between the main body and the seat needs to be adjusted, the extension plate 27 is moved in the first sliding groove 10. After adjustment, the second screw 30 and the nut 32 are screwed in to fix the extension plate 27 and the second bending section 11. The main body and the seat are then fixed using the first screw 28.

[0027] When the height of the support plate 21 needs to be adjusted, the limiting rod 13 is pushed to move closer to the limiting plate 26 so that the limiting rod 13 enters a different second limiting hole 15;

[0028] When the position of the supporting plate 21 needs to be adjusted, the supporting plate 21 is directly rotated. The supporting plate 21 rotates relative to the second connecting shaft 20, and the first limiting teeth 18 cooperate with the second limiting teeth 22 to perform gear adjustment.
