[0055] The workflow provided in Embodiment 1 of this utility model is as follows: The armrest is placed on the left or right side of the wheelchair armrest according to the patient's condition. When the patient sits in the wheelchair, they place their arm on the support component 3. The patient adjusts the guide rod 111 along the armrest direction using the first fastener 112 as needed, and adjusts the height of the support component 3 using the telescopic rod. The second fastener 21 is then adjusted to a relaxed state. When the hand is placed on the support component 3, the patient presses the support component 3 to rotate the universal ball 41, thereby inserting the second fastener 21 into the positioning hole 411, allowing for multi-angle adjustments to meet the needs of patients of different heights. When the patient does not need the support component 3 to support their arm, the support component 3 can be bent into a flat surface. In this case, the support component 3 can be used as a small table to place everyday items.
