It provides support through the armpits to help users maintain body balance, reduce the burden on the lower limbs, relieve pain during walking, and assist users in walking activities.

[0003] As people age and their physical strength declines, some people who use crutches to assist walking or the elderly will find it increasingly difficult to move, especially when they are moving from sitting to standing or from standing to sitting. Because of insufficient leg strength, many people will find the entire process very difficult, and even cannot complete it independently. If someone helps them, they can stand up or sit down, but if there is no one to help them, these people will be in a particularly embarrassing situation, and their movements will be restricted everywhere. Sometimes, due to insufficient leg strength, the speed of sitting down cannot be controlled by their consciousness during the sitting process. The second half of the sitting process is almost equivalent to the speed of free fall, which causes serious consequences such as damage to the coccyx or even fractures, and poses a serious risk to their health.

[0004] During the use of the existing crutches, it is not convenient to adjust the use length of the crutches, which affects the standing and sitting of the crutches users, reduces the flexibility of the crutches, and affects the comfort and walking stability of the users. Utility Model Content

DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 4 The electric power-assisted crutches include a crutches main body 1, a telescopic frame 5 is installed on the top of the crutches main body 1, the left and right ends of the top of the telescopic frame 5 are movably connected with adjusting rods 16, and an armpit support 7 is installed on the top of the adjusting rod 16.

[0025] The left and right ends of the top of the telescopic frame 5 are both equipped with a threaded clamp 6 which is sleeved on the surface of the adjusting rod 16. The threaded clamp 6 is provided with an opening, and a locking nut 8 is threadedly sleeved on the surface of the threaded clamp 6. The locking nut 8 is sleeved on the surface of the threaded clamp 6 to lock the adjusting rod 16.

[0026] By pulling the adjusting rod 16 inside the telescopic frame 5, the height of the axillary support 7 can be adjusted to change the use length of the axillary crutch. When the axillary support 7 reaches a suitable use position, the locking nut 8 is screwed onto the surface of the threaded clamp 6. The threaded clamp 6 is made of elastic plastic material. After the locking nut 8 is screwed onto the threaded clamp 6, the opening on the threaded clamp 6 is squeezed to deform the threaded clamp 6 inwardly to lock and fix the adjusting rod 16, thereby preventing the axillary support 7 from moving up and down.

[0027] The surface of the locking nut 8 is provided with a plurality of anti-skid grooves.

[0028] By providing the anti-slip groove, the friction force on the surface of the locking nut 8 can be increased, making it easier for the user to rotate the locking nut 8.

[0029] A micro motor 10 is installed at the top of the inner cavity of the armpit stick body 1, and the output shaft of the micro motor 10 is connected to a screw rod 2. A main support rod 14 is threadedly sleeved on the surface of the screw rod 2. A hollow cavity used in conjunction with the screw rod 2 and the main support rod 14 is opened inside the armpit stick body 1.

[0030] A limiting sleeve 13 is sleeved on the surface of the main support rod 14 , and the limiting sleeve 13 is slidably connected to the inner wall of the hollow cavity to limit the main support rod 14 .

[0031] The hollow cavity and the main support rod 14 are square in shape.

[0032] The bottom of the main support rod 14 is fixedly connected with an anti-skid pad 15, and the anti-skid pad 15 is made of rubber material.

[0033] By setting up the micromotor 10, it is convenient to drive the screw rod 2 to rotate. During the rotation of the screw rod 2, the main support rod 14 is driven to move inside the hollow cavity. During the movement of the main support rod 14, the limit sleeve 13 is driven to slide on the inner wall of the hollow cavity, thereby limiting the main support rod 14 to prevent it from rotating. When the micromotor 10 rotates forward, it drives the main support rod 14 to move upward and retract, making it convenient for the user to sit down. When the micromotor 10 reverses, the main support rod 14 moves downward and extends to assist the user to stand, thereby improving the flexibility of the armpit crutches during use. The anti-slip pad 15 is in contact with the ground, increasing the stability of the bottom of the main support rod 14.

[0034] A handle 9 is fixedly connected to the inner wall of the telescopic frame 5 , and an adjustment switch 4 is mounted on the handle 9 .

The lithium battery 11 can power electrical equipment, and the lithium battery 11 can be charged through the charging module 12.

[0038] The adjustment function enables the crutch to be precisely adjusted according to the user's specific height, arm length and physical condition, ensuring that the crutch's height matches the user's body proportions, thereby achieving the best support effect.

[0039] The right length of axillary cane helps maintain body balance and reduce the risk of falling. Users can quickly adjust the length according to different ground conditions or walking needs to ensure safe and stable walking in various environments.

[0040] The appropriate length of the crutches can help users maintain a correct walking posture and avoid body posture distortion caused by the crutches being too long or too short, thereby improving the naturalness and efficiency of walking.

[0041] By adjusting to the appropriate height, the crutches can effectively disperse the body weight and reduce the pressure on the lower limbs, while avoiding unnecessary compression and injury to the armpits, shoulders and upper limbs, reducing the risk of nerve compression, thereby improving the comfort of the user.

[0042] The adjustable-length crutches can accommodate a more diverse user group and also facilitate the phased adjustment needs during the rehabilitation process.

[0043] The electric power-assisted cane also has the following two characteristics:

[0044] 1. The upper part of the armpit stick has the advantage of manually adjusting the length, which is suitable for people of different heights;

[0045] 2. The lower part of the crutches has the advantage of electrically lifting and adjusting the length. The lifting force of the micromotor 10 can support the weight of the body, solving the problem of people who cannot stand up by themselves due to weak legs and feet, such as people with leg injuries and some elderly people.
