The wheelchair lifting device having such a configuration will be described below.
[0007] "Lifting both wheels of the wheelchair you are riding in off the ground via a fulcrum" refers to the state in which the V-shaped and L-shaped anti-slip devices of the holding means inserted under the lower frame of the wheelchair you are riding in use as a fulcrum to lift the wheelchair you are riding in and cause both wheels to spin freely. Next, "the holding means at the end of the U-shaped open section which is equipped with a V-shaped anti-slip device that receives a V2 line attached to both ends of the first pipe, an L-shaped anti-slip device on the other end, and a stable base that is suspended by fitting the second pipe in the middle" refers to a holding means located at the end of the wheelchair lift, which is equipped with a first pipe with protruding ends and fixed to the end of the U-shaped open section of a pipe frame made up of a first pipe, a V-shaped anti-slip device on one protruding part that receives the two outer diameter lines of the wheelchair under frame and two lines of the V-shaped inner wall of the anti-slip device on one protruding part, and an L-shaped anti-slip device on the other protruding part, and a stable base that is suspended by fitting a second pipe that has a diameter larger than the first central pipe.

These inconveniences were improved by attaching a rotation limiting band with a limiting groove to the first pipe, and by fixing a V-shaped anti-slip device or an L-shaped anti-slip device to this rotation limiting band with a limiting groove. In addition, the rotation of the rotation limiting band having a limiting groove is controlled by fitting the rotation control protrusion fixed to the first pipe into the limiting groove.
[0012] The other first pipe protrusion is cut off, and a shaft with a notch made in the cut-out area for insertion and withdrawal is attached to the symmetrical position of the end of the shaft. The cut first pipe is fitted and fixed to the first pipe in the same manner as above. A rotation control protrusion is fixed to the first pipe in the same manner as above. At the rotation control protrusion fixing position, the rotation control protrusion is inserted into the rotation control protrusion, covering the limiting groove of a rotation limiting band with a limiting groove, and the rotation limiting band with a limiting groove is attached. An L-shaped anti-slip device is further fixed to the rotation limiting band with a limiting groove. This L-shaped anti-slip device moves within the insertion and withdrawal width together with the notched shaft, allowing the width of the holding means to be freely adjusted.
[0013] "The wheelchair is lifted via a fulcrum, and both wheels are raised from the ground. To maintain this raised state, V-shaped and L-shaped anti-slip devices support the wheelchair lower frame, and a stable platform is suspended below them. The stable platform, which swings in a pendulum, positions the attached wire by tensioning and relaxing it, lands, and receives the wheelchair lower frame and raises it into a raised state" refers to the V-shaped and L-shaped anti-slip devices that support the wheelchair lower frame, which maintains this raised state, and the stable platform in the center of the holding means located below them, which is located under the wheelchair, and the triangular stable platform that supports the wheelchair lower frame ensures the raised state and makes it easy to wipe and clean the wheels. Effects of the invention
