[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5 This utility model provides an embodiment comprising two upright plates 1, each with a fixed plate 2 fixedly connected to its bottom surface. A distance adjustment component connects the two upright plates 1, and a common lifting component is connected to both upright plates 1. Two handles 12 are connected to the lifting component, allowing elderly patients to walk by gripping the handles 12. By setting up the lifting component, the height of the handles 12 can be adjusted according to the height of the elderly patient, reducing the difficulty of use, preventing falls or injuries during use, and improving safety. The lifting component includes a fixed plate 2 fixed to the upright plate 1. The first fixing block 4 is fixed to the side of the plate 1 and the second fixing block 5 is fixed to the side of another vertical plate 1. The top surface of the first fixing block 4 is rotatably connected to a threaded cylinder 6. The threaded cylinder 6 is threadedly connected to a threaded rod 7. The top end of the threaded rod 7 extends to the outside of the threaded cylinder 6 and is fixed to a connecting plate 11. The top surface of the second fixing block 5 is fixed to a cylinder 8. The cylinder 8 is slidably connected to a limit rod 9. The top end of the limit rod 9 extends to the top of the cylinder 8 and is fixed to a moving plate 10. The connecting plate 11 is slidably connected to the moving plate 10. The front side of the connecting plate 11 and the front side of the moving plate 10 are respectively fixed to two handles 12.

[0030] The distance adjustment assembly includes a dual-head motor 18 fixedly connected to the middle of the side of a vertical plate 1. Each output end of the dual-head motor 18 is fixedly connected to a lead screw 14. Each lead screw 14 is threadedly connected to a threaded sleeve 15. One side of each threaded sleeve 15 is rotatably connected to an adjusting rod 19. The ends of each adjusting rod 19 away from the threaded sleeve 15 are rotatably connected to the side of another vertical plate 1. The ends of each lead screw 14 away from the dual-head motor 18 are rotatably connected to a connecting block 13. Both connecting blocks 13 are fixedly connected to one vertical plate 1. One side of each threaded sleeve 15 is fixedly connected to a slider 16. Two symmetrical grooves 17 are formed on the side of one vertical plate 1, and the two sliders 16 are slidably connected to two grooves 17 respectively. The sliding groove 17 can improve the stability of the threaded sleeve 15 when it moves. A storage groove 21 is provided on one side of the connecting plate 11. The moving plate 10 is slidably connected in the storage groove 21. The distance adjustment component drives one upright plate 1 to move closer to the other upright plate 1, so that the walking aid for elderly patients can be folded, making the overall footprint of the walking aid smaller and easier to store. A moving groove 22 is provided on the inner surface of one side of the storage groove 21. A moving block 20 is fixed to one side of the moving plate 10. The moving block 20 is slidably connected in the moving groove 22. The bottom surfaces of the two fixed plates 2 are rotatably connected to universal wheels 3 with locking mechanisms. The universal wheels 3 are provided to facilitate the movement of the walking aid.

[0031] Working principle: During use, rotating the threaded cylinder 6 causes the threaded rod 7 to drive the connecting plate 11 and the moving plate 10 to rise and fall. The connecting plate 11 and the moving plate 10 then drive the handle 12 to rise and fall, allowing the height to be adjusted according to the height of the elderly patient, reducing the difficulty of use, preventing falls or injuries during use, and improving safety. The elderly patient can walk by holding the handle 12. When the walker is not in use, the dual-head motor 18 can be started. The dual-head motor 18 drives the two lead screws 14 to rotate, causing the two threaded sleeves 15 to drive the two adjusting rods 19 to move. The two adjusting rods 19 then move one upright plate 1 closer to the other upright plate 1. During the movement, the moving plate 10 also slides into the storage slot 21 in the connecting plate 11, allowing the walker to be folded, reducing the overall footprint of the walker and making it easier to store.
