The stair climbing power mechanism 22 comprises a speed reducing motor 2, a driving stair climbing wheel 3 and a one-way bearing 18; the active stair climbing wheel 3 is arranged between the two clamping mechanisms 19, the axis of the active stair climbing wheel 3 is vertically arranged, the speed reduction motor 2 drives the active stair climbing wheel 3 to rotate through the one-way bearing 18, and the speed reduction motor 2 is installed on the connecting plate 24.

Each clamping mechanism 19 comprises an extended U-shaped frame 26, two clamping wheels 13, four springs 17 and four supporting rods 27; the two clamping wheels 13 are arranged in a groove of the U-shaped frame 26 extending outwards, the axes of the two clamping wheels 13 are horizontally arranged, through holes are formed in the two ends of the wheel shaft of each clamping wheel 13, the two ends of the wheel shaft are slidably sleeved on the corresponding supporting rods 27, the four supporting rods 27 are fixed on the U-shaped frame 26 extending outwards, the four springs 17 are sleeved on the four supporting rods 27, and the four springs 17 are used for supporting the wheel shafts of the corresponding clamping wheels 13.

Each clamping mechanism 19 also comprises two anti-skid rubber blocks I20; the two anti-skid rubber blocks I20 are attached to two extensions of the extended U-shaped frame 26.

The pipe wrench type old-people-assisting stair-climbing crutch further comprises two anti-skid rubber blocks II 12, the two anti-skid rubber blocks II 12 are arranged on two sides of the active stair-climbing wheel 3 of the stair-climbing power mechanism 22, and the two anti-skid rubber blocks II 12 are fixed on the connecting plate 24.

The pipe wrench type old-people-assisting stair-climbing crutch further comprises a large fixed foot 10, and the large fixed foot 10 is installed at the lower end of the straight rod part 9 of the crutch body 21.

The pipe wrench type walking stick for helping the old to climb stairs further comprises a storage rack 11, and the storage rack 11 is installed on the straight rod part 9 of the walking stick body 21.

The pipe wrench type old-people-assisting stair-climbing crutch further comprises a GPS, a fall alarm, a night lamp and a battery, the GPS, the fall alarm, the night lamp and the battery are installed on the straight rod part 9 of the crutch body 21, and the battery supplies power to the GPS, the fall alarm and the night lamp.

The using method comprises the following steps: the old holds the armrest part 1 of the crutch body 21, and can assist the walking for the old with bad legs and feet.

When climbing stair, the old man shortens walking stick body 21 to the shortest, thereby transversely arranges walking stick body 21 on the handrail of stair again, thereby drives gear 8 and rack 7 through unscrewing knob 15 and meshes the transmission, thereby drives slider 6 and slides on guide rail 4, thereby makes the initiative climb building wheel 3 and four centre gripping wheels 13 of relative setting and press from both sides tight stair handrail, then rotatory jackscrew two 16 makes slider 6 can't slide on guide rail 4. The first jackscrew 14 is unscrewed, so that the straight rod part 9 of the crutch body 21 can rotate around the pin shaft 5, and the clamping opening can be reduced and cannot be expanded due to the shape of the groove of the slide block 6.

The old man holds the straight rod part 9 of walking stick body 21, and gear motor 2 drives the initiative through the shaft joint and climbs building wheel 3, drives walking stick body 21 and upwards scrambles. The wheel shaft of the active stair climbing wheel 3 is connected with another one-way bearing 18, and the two one-way rotating directions are opposite, so that the stair climbing driven by the motor can be realized, and the stair climbing can be manually pushed after no point exists. When the gear motor 2 drives the crutch body 21 to climb up a step, the old man utilizes the arm to pull the old man to walk forward, and at the moment, the four anti-skidding rubber blocks I20 tightly utilize the friction with the stair handrail to prevent backward skidding, which is similar to a tool of a climbing pole. When the old man lifts up, the arm of the old man presses the crutch body 21 downwards, the clamping opening is reduced, at the moment, the four clamping wheels 13 are pressed into the crutch body 21, and meanwhile, the two anti-skid rubber blocks II 12 and the four anti-skid rubber blocks I20 tightly lock the stair handrail like universal pipe tongs. Thereby overcoming the axial force and preventing back-slip. After the old people lift the arm after the step is finished, the eight springs 17 push the clamping wheel 13 out of the crutch body 21, so that the crutch body 21 can continue to slide upwards.

And (5) loosening the knob 16 after climbing stairs, and releasing the locking between the sliding block 6 and the guide rail 4. And the second jackscrew 16 is screwed to prevent the straight rod part 9 of the crutch body 21 from rotating around the pin 5. And rotating the first knob 15 to drive the rack-and-pinion mechanism, so that the clamping opening is enlarged, screwing the first knob 15 again, and taking the crutch body 21 down from the handrail. The crutch body 21 can be used again as the crutch body 21 after being placed on the ground and the straight rod part 9 of the crutch body 21 is lengthened.

The article shelf 11 can be used for placing a folding stool for the old with the legs and feet inconvenient so as to sit down to have a rest when the old is tired when walking, and can also prevent articles such as water cups and the like.

The design of fixing the big four feet 10 can make the crutch body 21 stand on the ground without leaning on the wall surface and the like, thereby preventing the crutch from falling on the ground and being inconvenient for the old to pick up. The method is the best choice for the old with unstable walking.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
