[0034] Embodiment 2

[0035] Reference Figure 5-Figure 6 , a fall-prevention walker, the folding seat comprises a fixed rod 12, a first rotating plate 13, a fourth connecting rod 15, a second rotating plate 16, a sliding groove 17 and a sliding block 18, the inner side of one side of the second connecting rod 3 is fixed with the fixed rod 12, the outer side of the fixed rod 12 is rotatably connected with the first rotating plate 13, both ends of the first rotating plate 13 are fixed with the fourth connecting rod 15, the outer sides of the two fourth connecting rods 15 are rotatably connected with the second rotating plate 16, the inner sides of the two first connecting plates 2 away from each other at one end are provided with sliding grooves 17, the inner sides of the two sliding grooves 17 are slidably connected with sliding blocks 18, and the sliding blocks 18 are rotatably connected with the corresponding second rotating plates 16, and a fixing component is arranged on the first connecting rod 1, and the fixing component is used to fix the first rotating plate 13; through the design of the folding seat, when the elderly are physically exhausted when using the auxiliary support device, they can take a timely rest to avoid falling due to excessive fatigue.

[0036] The fixing assembly includes a fixing plate 19, a clamping block 20, a spring 21 and a lifting plate 22. The fixing plate 19 is fixed to the outer side of the first connecting rod 1, and the clamping block 20 is slidably connected to the inner side of the fixing plate 19. The clamping block 20 is plugged into the clamping groove 14, and springs 21 are fixed to both ends of the top of the clamping block 20. The design of the spring 21 can push the clamping block 20 to better clamp with the clamping groove 14. The tops of the two springs 21 are fixed to the fixing plate 19, and a lifting plate 22 is fixed to one side of the clamping block 20. The lifting plate 22 is slidably connected to the fixing plate 19. The design of the fixing assembly enables the first rotating plate 13 to be well fixed on the auxiliary support device, which facilitates the movement of the auxiliary support device.

[0037] The top ends of the outer sides of the two anti-fall frames 5 are each provided with a sponge cover 23. The design of the sponge cover 23 enables the elderly to better grasp the auxiliary support device. The sponge cover 23 has good sweat absorption and will not cause a loose grip due to hand sweat. A snap-fitting groove 14 is provided on the inner side of one side of the first rotating plate 13, and a 24 is provided on the inner side of the fixed plate 19.

[0038] The use process of the anti-fall walker provided by the utility model is as follows: when it is necessary to adjust the distance between the two anti-fall frames 5 according to individual differences, start the rotating motor 8, and the output end of the rotating motor 8 drives the first bevel gear 9 to rotate. Since the first bevel gear 9 is meshed and connected with the second bevel gear 10, the rotation of the first bevel gear 9 drives the second bevel gear 10 to rotate, so that the bidirectional threaded rod 11 fixedly connected to the second bevel gear 10 also rotates, and since the bidirectional threaded rod 11 is threadedly connected with the two connecting members 4, the bidirectional threaded rod 11 drives the two connecting members 4 to move, and since the connecting member 4 is fixed to the anti-fall frame 5, the distance between the two anti-fall frames 5 is adjusted, so that the walking aid device can adapt to the individual differences of the applicable population;

[0039] When the elderly are exhausted from using the auxiliary support device and need to take a rest, they pull the lifting plate 22 upwards. Since the lifting plate 22 is fixedly connected to the clamping block 20, the movement of the lifting plate 22 drives the clamping block 20 to move, so that the spring 21 fixed to the clamping block 20 is compressed. At this time, the clamping block 20 is no longer plugged into the clamping groove 14, the first rotating plate 13 is rotatably connected to the fixed rod 12, and the fixed rod 12 is fixed to the second connecting rod 3. At this time, the first rotating plate 13 is rotated downwards. Since the first rotating plate 13 is fixedly connected to the fourth connecting rod 15, the first rotating plate 1 The rotation of the second connecting rod 15 drives the fourth connecting rod 15 to rotate, so that the second rotating plate 16 rotatably connected to the fourth connecting rod 15 also rotates, and the second rotating plate 16 is rotatably connected to the sliding block 18, and the sliding block 18 slides on the inner side of the sliding groove 17, so that the rotation of the fixed plate 19 drives the sliding block 18 to slide downward. At this time, the first rotating plate 13 is fully unfolded, and the two second rotating plates 16 provide support for the first rotating plate 13, so that the elderly can sit on the first rotating plate 13 to restore their physical strength when they feel tired while walking with the auxiliary support device, so as to avoid falling due to excessive fatigue.
