[0002] At present, patients who have undergone lower limb orthopedic surgery and patients with upper and lower limb fractures in clinical practice mostly use walkers for postoperative exercise and recovery of walking during rehabilitation exercises. Walkers are mostly used for patients who need functional exercises, such as: the elderly after orthopedic surgery, patients after hip and knee replacement surgery, and other disabled people who have no confidence in maintaining balance while walking, can also use walkers to assist them in walking.

[0003] For example, Chinese patent publication number CN218391587U discloses a walker, including a walker body, the top of the walker body is fixedly connected to a limit frame, and the limit frame is internally abutted against a moving block, the internal hinge of the moving block is hinged with a hinged push, and the end of the hinged push away from the moving block is fixedly connected to a fixed handle, the bottom surface of the moving block is fixedly connected to a first slider, the outer surface of the fixed handle is wrapped with an anti-slip pad, and the inner wall of the fixed handle is glued with a protective pad. The utility model can make the driving plate push the push rod to move by pressing the pressing rod, and can easily push the limit pin to retract into the interior of the moving block.

A second sliding groove 14 is opened on the side wall of the support rod 15 on the left side of the bottom of the two cross bars 1, and a sliding rod 13 is slidably connected in the two second sliding grooves 14. One end of the two sliding rods 13 extends out of the second sliding groove 14, and a rotating groove 10 is opened on the top side wall of the support rod 15 on the right side of the bottom of the two cross bars 1. The two rotating grooves 10 are rotatably connected to the bottom side walls with threaded rods 9, and the tops of the two threaded rods 9 pass through the corresponding cross bars 1 and are rotatably connected to the cross bars 1. The tops of the two threaded rods 9 are fixedly connected with a rotating block 5, and the two right support rods 1 are fixedly connected with a rotating block 5. A first sliding groove 11 is provided on the side wall of the support rod 15, one end of the two sliding rods 13 passes through the corresponding first sliding groove 11 and is slidably connected to the first sliding groove 11, one end of the two sliding rods 13 is respectively threadedly connected to the outer ring side wall of the two threaded rods 9, the top side walls of the two sliding rods 13 are fixedly connected with vertical plates 12, the tops of the two vertical plates 12 are fixedly connected with supporting plates 3, through grooves 2 are provided on the side walls of the two cross bars 1, the two supporting plates 3 are respectively slidably connected in the two through grooves 2, the top side walls of the two cross bars 1 are fixedly connected with handles 4, the outer side walls of the two handles 4 are provided with rubber pads, a connecting rod 6 is fixedly connected between one ends of the two cross bars 1, a fixing rod 18 is fixedly connected between the two support rods 15 on the right side, and a rest device is provided on the side wall of the fixing rod 18.

[0027] See also Figure 1-5The rest device includes two baffles 16, which are fixedly connected to the side walls of the fixing rod 18. A seat board 17 is rotatably connected between the two baffles 16 through a rotating shaft. An iron sheet 19 is provided on the side wall of the seat board 17, and a magnet 20 is provided on the side wall of the fixing rod 18. The magnet 20 is adsorbed and connected to the iron sheet 19. The bottoms of the two baffles 16 are commonly fixedly connected to the bottom plate 7. When the patient needs to rest, the seat board 17 is rotated to make the iron sheet 19 on the side wall of the seat board 17 separate from the surface of the magnet 20, and then the seat board 17 is placed on the side wall of the bottom plate 7, so as to support the seat board 17, and the patient can sit on the seat board 17 to rest. After resting, the seat board 17 is rotated to make the iron sheet 19 on the side wall of the seat board 17 adsorbed on the surface of the magnet 20, so as to adsorb and fix the seat board 17.

[0028] See also Figure 1 , Figure 3-5 The side walls of the seat board 17 are provided with rubber cushions to improve the comfort of the patient when sitting on the seat board 17.

[0030] See also Figure 1-2 The top side walls of the two support plates 3 are both arranged in an arc shape, so that when the support plates 3 are against the patient's armpits, they will not deviate from the patient's armpits.

[0031] The working principle of the utility model is as follows: when the patient needs to walk with the aid of the walker, the patient can support the body by holding the handle 4. When the patient uses the walker for a long time, the rotating block 5 can be rotated, and the rotating block 5 drives the threaded rod 9 to rotate. When the threaded rod 9 rotates, it can drive the sliding rod 13 to move up and down in the first sliding groove 11. The sliding rod 13 can drive the vertical plate 12 to move, and the vertical plate 12 drives the supporting plate 3 to move up and down. By rotating the rotating block 5, the supporting plate 3 is driven to move upward until the supporting plate 3 is against the patient's armpit, thereby reducing the burden on the patient's arm and preventing the patient from arm fatigue.

[0032] When the patient needs to rest, the seat board 17 is rotated to make the iron sheet 19 on the side wall of the seat board 17 separate from the surface of the magnet 20, and then the seat board 17 is placed on the side wall of the base plate 7 to support the seat board 17. The patient can sit on the seat board 17 to rest. After resting, the seat board 17 is rotated to make the iron sheet 19 on the side wall of the seat board 17 adsorbed on the surface of the magnet 20, thereby adsorbing and fixing the seat board 17.
