A lifting aid includes a urging portion, a point portion, a stretching portion and a restricting portion； the urging portion is a handle structure and is provided with an accommodating space； the fulcrum portion is a hollow cylinder and is inside the hollow portion The wall surface is provided with a plurality of engaging members, and the fulcrum portion and the urging portion have a settable length； the stretching portion includes an automatic resetting member and a telescopic member, and the automatic resetting member is disposed in the accommodating space. The telescopic element is connected to the automatic resetting element at one end to form a linkage, and the other end is connected to the fulcrum and embedded in one of the engaging members； the limiting portion is coupled to the telescopic element and is movable to move on the telescopic element to adjust the positioning. For determining the settable length, wherein the handle structure provides the user with a force, and the fulcrum portion provides the user with the sole as a fixed fulcrum, and the user applies a force to extend the telescopic element toward the fulcrum portion to change The length can be set, and the restoring force is provided by the automatic resetting element in the opposite direction, so that the user gets up by the restoring force. Thereby, the user can assist the user to pass through the mechanical angle of the human body structure in a sitting or lying state, and use the foot as a fulcrum to generate the strength of the body to achieve the effect of assisting to get up.一種起身輔助裝置，包括一施力部、一支點部、一拉伸部以及一限制部；施力部為一手把結構且設有一容置空間；支點部為一中空柱體且於該中空內部的壁面設有多個卡合件，該支點部與該施力部之間具有一可設定長度；拉伸部包含一自動復位元件與一伸縮元件，該自動復位件配置於該容置空間中，該伸縮元件一端連接該自動復位元件以形成連動，另一端連接該支點部且嵌設於其中一該卡合件；限制部組接該伸縮元件且可活動地於該伸縮元件上移動以調整定位，用以決定該可設定長度，其中手把結構提供該使用者施力，支點部提供使用者以足底作為固定支點，藉由使用者施力以使該伸縮元件朝支點部方向延伸以改變該可設定長度，且由自動復位元件提供反方向之回復力，從而使使用者受該回復力而起身。藉此，能輔助使用者在坐姿或者平躺等等狀態下透過人體構造的力學角度，以足部作為支點而產生起身的力量達成輔助起身的功效。
