A step-type fixed- stroke walking aid includes at least one control lever having a handle end arranged at one end of the control lever, and a ground end arranged at the other end opposite to the handle end at least one follower lever having a pivot end arranged at one end of the follower lever, and a supporting end arranged at the other end opposite to the pivot end, in which the pivot end is pivoted to the handle end adjacent to the control lever and at least one linkage mechanism forming a pivotal portion, in which the pivotal portion includes a first connecting rod and a second connecting rod extended outward. The first connecting rod is pivoted to a portion adjacent to the ground end. The second connecting rod is pivoted to a portion adjacent to the supporting end. The pivotal portion is connected with an elastic member, and the other end of the elastic member connects to the pivot end of the follower lever, in order to control the longest and the shortest distances between the ground end of the control lever and the supporting end of the follower lever, such that the pivot end can be rotated to perform stepping between the control lever and the follower lever for assisting walking.一種跨步式定距移動助行器,其包括有:至少一個控制桿一端設有一個把手端,及相反於把手端的一端設有一個抵地端,至少一個從動桿一端設有一個樞接端,及相反於樞接端的一端設有一個抵撐端,該樞接端樞設於鄰近該控制桿之把手端,至少一個連動機構形成有一個樞轉部,該樞轉部向兩端延伸有一個第一連桿與一個第二連桿,該第一連桿端樞接於鄰近抵地端處,該第二連桿端樞接於鄰近抵撐端處,該樞轉部處連接有一個彈性件,該彈性件另一端連接於從動桿之樞接端,且控制該控制桿之抵地端與從動桿之抵撐端之間的一個最長距離與一個最短距離,讓該控制桿與該從動桿之間以樞接端樞轉進行跨步式之助行效果。1...助行器10...控制桿11...把手端12...抵地端121...按壓鈕13...橫桿131...套管132...滑槽14...凸塊15...伸縮桿151...大口徑管152...小口徑管153...彈性體16...腳管161...穿孔20...從動桿21...樞接端211...接合片22...抵撐端221...按壓鈕23...腳管30...連動機構301...樞轉部31...第一連桿32...第二連桿33...彈性件34...軟性體
