[0029] Embodiment 1:

[0030] This embodiment provides an adjustable-height door handle, including:

[0031] A first handle 1, including a first handle 11 and a first connecting part 12 connected to one end of the first handle 11;

[0032] A second handle 2, located below the first handle 1. The second handle 2 includes a second handle 21, a second connecting part 22 connected to one end of the second handle 21, and a connecting piece 23 rotatably connected to the second connecting part 22;

[0033] A height adjusting part 3, located between the first connecting part 12 and the second connecting part 22;

[0034] A length adjusting rod 4, with both ends respectively hinged to the first handle 11 and the second handle 21;

[0035] Among them, a plurality of first mounting holes 5 are arranged in sequence from top to bottom on the height adjusting member 3, and the connecting member 23 is connected to the first mounting hole 5 through a screw.

[0036] In this technical solution, the first handle 1 and the second handle 2 can be made of metal materials, such as stainless steel and aluminum alloy. The first connecting portion 12 and the first handle 11 can be welded or integrally formed, and the second connecting portion 22 and the second handle 21 can be welded or integrally formed.

[0037] The first connecting portion 12 is rotatably connected to the door, and by rotating the first handle 11, the door lock can be opened.

[0038] The second connecting portion 22 is rotatably connected to the connecting member 23, and the connecting member 23 is fixedly connected to the height adjusting member 3, so that the second handle 21 can rotate.

[0039] The height adjusting member 3 can be made of metal or plastic. The height adjusting member 3 can be fixed to the surface of the door using screws or pasted on the door using tape. The first mounting hole 5 can be a threaded hole, and the connecting member 23 can be a plate-like structure. The connecting member 23 and the height adjusting member 3 are fixedly connected by screws.

[0040] The length adjusting rod 4 can be a rod-like structure with the effect of adjusting the length. When adjusting the height of the second handle 2 through the height adjusting member 3, the length of the length adjusting rod 4 also needs to be adjusted.

[0041] In use, the length of the length adjusting rod 4 is adjusted to a suitable length, and the height of the second handle 2 is adjusted to a suitable height through the height adjusting member 3. The height of the second handle 2 is adjustable and can adapt to people of different heights. A quadrilateral is formed among the length adjusting rod 4, the first handle 1, the second handle 2, and the height adjusting member 3. When the length adjusting rod 4 and the height adjusting member 3 are adjusted to the same length, the second handle 21 can be kept parallel to the first handle 11.

[0042] Since the position of the height adjusting member 3 is fixed, an adult with a tall height can turn the first handle 1 by hand to open the door, and a person with a short height can turn the second handle 2 clockwise. The second handle 21 pulls the first handle 11 through the length adjusting rod 4, causing the first handle 1 to rotate clockwise, forming a parallelogram, thereby opening the door.
