Description
technical field [0001] The utility model relates to a crank type artificial driving device of a wheelchair, which belongs to the field of articles for the disabled. Background technique [0002] People who cannot walk use a wheelchair as a means of transportation, and the armrest circle of the wheelchair can be rotated by the arm of the upper limb to achieve the purpose of moving. However, in the process of rotating the wheelchair, because the sleeves of the disabled are often in contact with the wheels of the wheelchair, the dust on the wheels pollutes the clothes, which cannot meet the requirements for clean clothes. Contents of the invention [0003] The purpose of this application is to provide a kind of manual drive device of the crank type of wheelchair, eliminates above-mentioned defect with this. The device is composed of friction wheels, bearing seats, universal joints, connecting shafts and crank handles; friction wheels are respectively arranged on the slopes o...
