[0002] Elderly care emphasizes maintenance and recovery, promoting health, preventing and controlling disabilities caused by acute and chronic diseases, giving full play to the elderly's daily living ability, achieving the optimal function of the elderly body, and maintaining the dignity and comfortable life of the elderly. Among the nursing tools commonly used by the elderly, crutches are the tools that most elderly people need to use. Crutch is an important medical rehabilitation aid.

[0003] According to the Chinese patent application number: CN202122229995.7, a special crutch for the elderly is disclosed, including a fixed column, a balance component is threadedly connected to the bottom of the fixed column, a seat component is arranged on the outer surface of the fixed column, a telescopic rod is slidably connected to the inside of the fixed column, a driving handle is fixedly connected to the top of the telescopic rod, a clock is arranged on one side of the top of the driving handle, and a plurality of clamping holes are provided on the outer surface of the telescopic rod. The utility model not only improves the stability of the elderly's crutches when in use through the setting of the balance component, but also can be converted according to the inclined surface of the ground, thereby improving the stability of the crutches, and through the setting of the seat component, it is convenient to provide a resting position for the elderly, and through the telescopic movement of the telescopic rod, the length of the crutches can be adjusted, which meets the use of elderly people of different heights and improves the use effect of the crutches, and through the setting of the clock, it is convenient for the elderly to know the time in time, further improving the functionality of the crutches.

[0004] At present, there are still some shortcomings in a special crutch for the elderly. For example, when an elderly patient chooses a crutch, he generally needs to choose a crutch of suitable length according to his height. The crutch can be adjusted in length by a telescopic rod, but the elderly patient needs to bend down or squat to pull out the pin, and then insert the pin after the adjustment is completed. It is very inconvenient for elderly patients with bad waists to adjust the length of the crutch. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an easy-to-use adjustable exercise crutch for the elderly, which solves the problem that the length of the crutch can be adjusted by a telescopic rod, but the elderly patient needs to bend down or squat to pull out a pin, and then insert the pin again after the adjustment is completed. For elderly patients with bad waists, it is very inconvenient to adjust the length of the crutch.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] The cam is configured to move the outer sleeve of the outer sleeve toward the outside of the support rod, and the cam is configured to move the outer sleeve toward the outside of the support rod, wherein the cam is configured to move the outer sleeve toward the outside of the support rod, and the cam is configured to move the outer sleeve toward the outside of the support rod.

[0008] By adopting the above technical solution and setting up a lifting component, when an elderly patient uses the crutch, he needs to select a crutch of a suitable length according to his height. The elderly patient can start the rotating motor inside the inner support rod by pressing the control button. The rotating motor drives the screw rod to rotate, so that the lifting ring in the outer support rod can be lifted up and down in the screw rod, so that the outer support rod can be extended or contracted in the inner support rod, thereby adjusting the height of the outer support rod.
