The height of the entire walking aid is adjusted by designing a height adjustment structure to meet the use of users of different heights or users with different habits, and has good versatility. If the walking support is too high, it will directly touch the armpit, and pressing the axilla on the walking support to support the body weight will compress the arm from the nerve, axillary nerve, axillary lymph, and blood vessels. When the walking aid in the present invention is used, the height of the main frame 10 can be adjusted by adjusting the height adjustment structure, so that the highest part of the walking aid, that is, the top surface of the support assembly 20 is two to 2 inches below the armpit. Three inches (the correct crutch posture cannot directly place the walking aid under the armpit), and the curved section 111 of the upper rod 11 is bent toward the side where the user is located, so as to ensure that the support assembly 20 is inwardly attached to the side of the user. The rib of the chest wall on the side of the armpit distributes the pressure, which can greatly reduce the pressure of the support component 20 under the armpit. When using a pair of walking aids, the two support assemblies 20 are inwardly attached to the ribs of the chest wall on both sides of the armpit, which can prevent the body from shaking. In addition, when the upper limb is exerted when using the traditional walking aid, the wrist is flexed, and the forearm is pronated, which may easily lead to medial epicondylitis, namely tennis elbow, when the patient is on crutches for a long time. However, in the invention, since the wrist can be grasped upright, and the grasping handle 40 matches the angle of the human hand formed during grasping, the above-mentioned problem does not occur.

Optionally, a fixing sleeve 13 may be provided at the connection between the upper rod 11 and the lower rod 12 , so as to cover and fix the connection between the upper rod 11 and the lower rod 12 .
