Action 2 understands that 'the invention is available for the body to be unilaterally unable to use the foot and use the self-drive = chair 2: t unilateral Kang side actionable hand control lever control line ^ /, middle 疋 疋 手 手 椅 椅 椅 椅 椅 椅 椅 椅 椅 椅 椅 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 ' ' ' ' ' ' ' ' ' ' ' ' On the way, the wheelchair also uses the file--^:Ι:ΙΓΛ? to drive the wheelchair to travel. The way to provide the residual ρ early, with its own strength alone, the hair can not provide two new manual wheelchairs: Technical solution, can solve the problem of the second, at the same time, the hair of the person... Take the direct control method 々 y = k ^ The type wheel h is used in the operation, because the displacement is clear, the steering angle is large and the driving mode 11 1297601 is comfortable. It is labor-saving, so that the disabled can be harmed for a long time. Therefore, the present invention is indeed wheelchair-friendly, and there is no wheelchair injury, which is very useful and practical.圃You invented the second figure of the wheelchair in the first picture of the first picture.
