[0024] By adopting the above technical solution, when using the seat cushion body 5, loosening the fastening knob 21 allows one end of the seat cushion body 5 to rotate through the rotating shaft 22. Then, through the fixing component 23 inside the mounting block 24, the seat cushion body 5 can be assisted and supported, so that the patient can temporarily sit on the upper part of the seat cushion body 5 for use.

[0025] Specifically, the fixing component 23 includes a spring 231, a handle 232, a pull rod 233, a support rod 234, and a limiting plate 235. The limiting plate 235 is provided inside the mounting block 24. The support rod 234 is provided on one side of the limiting plate 235, and the pull rod 233 is provided on the other side of the limiting plate 235. The handle 232 is provided at the other end of the pull rod 233, and the spring 231 is sleeved on the surface of the pull rod 233 inside the mounting block 24.

[0026] By adopting the above technical solution, pulling the handle 232 will pull the lever 233, which will pull the limiting plate 235 and compress the spring 231. At the same time, the support rod 234 will be inserted into the mounting block 24. Then, the seat cushion body 5 will be rotated through the rotating shaft 22 and will pass the upper end of the mounting block 24. After releasing the handle 232, the spring 231 will rebound, thereby causing the support rod 234 to extend out and provide auxiliary support to the seat cushion body 5.

[0027] Specifically, the mounting block 24 has a circular groove inside that corresponds to the limiting plate 235, and through holes at both ends of the circular groove that correspond to the pull rod 233 and the support rod 234.

[0029] In this embodiment, when using the seat cushion body 5, loosen the fastening knob 21, pull the handle 232, the handle 232 pulls the pull rod 233, the pull rod 233 pulls the limiting plate 235 and causes the spring 231 to compress, at the same time causing the support rod 234 to be inserted into the mounting block 24. Then, rotate the seat cushion body 5 through the rotating shaft 22 and pass the upper end of the mounting block 24, then release the handle 232. At this time, the spring 231 rebounds, thereby causing the support rod 234 to extend out to provide auxiliary support for the seat cushion body 5. Example 2

[0030] The difference between this embodiment and embodiment 1 is that the height adjustment mechanism 3 of the walking aid includes an inner rod 31, a second fixing component 32, a fixing hole 33 and an outer rod 34. The lower end of the walking aid bracket 1 is provided with an inner rod 31, the lower end surface of the inner rod 31 is provided with an outer rod 34, the lower end of the inner rod 31 is provided with a second fixing component 32, and the side of the outer rod 34 is provided with multiple sets of fixing holes 33 corresponding to the second fixing component 32.

[0031] By adopting the above technical solution, when adjusting the height of the walker, the limiting of the fixing component 2 32 on the fixing hole 33 is released. At this time, the inner rod 31 and the outer rod 34 can slide relative to each other, and the lower ends of the four sets of walker brackets 1 can be adjusted respectively. After the adjustment is completed, the height of the walker can be adjusted by using the fixing component 2 32 in conjunction with the fixing hole 33.

[0032] Specifically, the fixing component 32 includes a locking pin 321, a limiting plate 322, and a spring 323. The lower end of the outer rod 34 has the spring 323 inside, the other end of the spring 323 has the limiting plate 322, and the other end of the limiting plate 322 has the locking pin 321.

[0033] By adopting the above technical solution, pressing the locking pin 321 compresses the limiting plate 322 and the spring 323, causing the locking pin 321 to slide out from the inside of one set of fixing holes 33. At this time, the lengths of the inner rod 31 and the outer rod 34 can be adjusted. After the adjustment is completed, when the locking pin 321 is aligned with the other set of fixing holes 33, the spring 323 rebounds, thereby driving the locking pin 321 to insert into the inside of the other set of fixing holes 33, so as to realize the height adjustment of the walker.

[0034] In this embodiment, when adjusting the height of the walker, pressing the locking pin 321 compresses the limiting plate 322 and the spring 323, causing the locking pin 321 to slide out from the inside of one set of fixing holes 33. At this time, the lengths of the inner rod 31 and the outer rod 34 can be adjusted. After adjustment, when the locking pin 321 is aligned with the other set of fixing holes 33, the spring 323 rebounds, thereby driving the locking pin 321 to insert into the inside of the other set of fixing holes 33, so as to realize the height adjustment of the walker.

[0035] The working principle and usage process of this utility model are as follows: When using the seat cushion body 5, loosen the fastening knob 21, pull the handle 232, the handle 232 pulls the pull rod 233, the pull rod 233 pulls the limiting plate 235 and causes the spring 231 to compress, simultaneously causing the support rod 234 to embed into the mounting block 24. Then, rotate the seat cushion body 5 through the rotating shaft 22 until it passes the upper end of the mounting block 24, then release the handle 232. At this time, the spring 231 rebounds, thereby driving the support rod 234. Extend to provide auxiliary support for the seat body 5; when adjusting the height of the walker, press the locking pin 321, the locking pin 321 compresses the limiting plate 322 and the spring 323, so that the locking pin 321 slides out from the inside of one set of fixing holes 33. At this time, the length of the inner rod 31 and the outer rod 34 can be adjusted. After the adjustment is completed, when the locking pin 321 is aligned with the other set of fixing holes 33, the spring 323 rebounds, thereby driving the locking pin 321 to insert into the inside of the other set of fixing holes 33, so as to realize the height adjustment of the walker.
