The connecting mechanism 200 can be used to adjust the distance between the two wheelchair bodies 100, so that the entire wheelchair can be folded and does not occupy space when not in use. In addition, the connecting mechanism 200 can also change the distance between the two wheelchair bodies 100 according to the actual body shape of the user, so that the space area formed between the two wheelchair bodies 100 is more in line with the body size of the user.

[0030] Furthermore, in the present embodiment, the wheelchair body 100 comprises a support frame 101, a coplanar armrest frame 102 is fixedly mounted on the top of the support frame 101, a vertical rod 103 is also fixedly mounted on one end of the top of the support frame 101, a push handle 103a is extended from the top end of the vertical rod 103, the two vertical rods 103 are connected via a backrest assembly 400, a brake assembly 104 is fixedly mounted on the side of the top of the support frame 101 away from the vertical rod 103, a support leg assembly 105 is mounted on the outer side of one end of the support frame 101 away from the vertical rod 103, the brake assembly 104 is used to brake the walking mechanism 300, and the support leg assembly 105 can support the user's footsteps.

[0031] Preferably, a detachable bottle hook rod is provided on the handrail frame 102, and the bottle hook rod itself is retractable, so that the operator can install the bottle hook rod on the handrail frame 102 and adjust the height at will to facilitate infusion.

[0032] Further, in this embodiment, the walking mechanism 300 includes a strip plate 301, a curved block 302 is fixedly installed on the top of the strip plate 301, a curved groove 303 is opened on the side of the curved block 302 facing the wheelchair body 100, a vertical plate 304 is fixedly installed on the top of the curved block 302, a fixed shaft 306 is fixedly installed inside the vertical plate 304, a walking wheel 305 is rotatably installed on the end of the fixed shaft 306 away from the wheelchair body 100, a universal mount 307 is installed on the outside of the end of the strip plate 301 away from the vertical rod 103, and a steering wheel 308 is installed at the bottom of the universal mount 307.
