[0002] With the aggravation of social aging, more and more elderly people have physical dysfunction, impairment, and lifelong disability due to aging or diseases. At this time, choosing a suitable assistive tool can better help patients with rehabilitation exercises and ensure the safety of patients. The function of a cane is to support body weight, maintain standing balance, and assist walking, so as to compensate for and improve the walking ability, thereby ensuring the safety of patients. At present, there are single-foot, three-foot, and four-foot canes on the market, each with its own advantages and disadvantages:

[0003] 1. Single-foot cane

[0004] Advantages: Light weight, convenient for going up and down stairs, and a wide range of use environments.

[0005] Disadvantages: On flat ground, the stability is worse than that of a four-foot cane.

[0006] 2. Four-foot cane

[0007] Advantages: More stable on flat ground.

[0008] Disadvantages: Not suitable for going up and down stairs and uneven roads. Only slow walking is allowed, and it is unstable during fast walking.

[0009] The Chinese patent with the publication number of CN216258165U discloses a portable rehabilitation cane, which relates to the technical field of canes. It includes a handle, and a fixing rod is fixedly installed at the bottom of the handle. A switch is arranged on the left side of the fixing rod at the bottom of the handle. The utility model is provided with a locking mechanism and a shock absorption component. Press the knob downwards, and through the magnetic attraction connection between the first magnet and the second magnet, the knob is fixed. The knob drives the connecting plate to move upwards through the pull rope, so that the sleeve is separated from the hinge and the folding rod, making the folding rod easy to fold and store, thus being convenient to carry. When in use, rotate the folding rod to be in a straight line with the fixing rod, and dial the knob outwards. The connecting plate moves downwards under the action of the spring, so that the sleeve is sleeved with the hinge and the folding rod, so that the folding rod is fixed to the fixing rod. The operation is convenient and fast. At the same time, four anti-slip feet are in contact with the ground to play a role in anti-slip for the device. At the same time, the airbag deforms under pressure to play a role in shock absorption and buffering for the device.
