This creative department provides an improved folding structure of a walker, which mainly includes two tripods combined with a crossbar and two folding mechanisms for folding. The tripod has a front frame, a grip bar and a rear frame. There is a folding mechanism between the two ends of the crossbar. There is a grip below the grip, a protrusion on the inner wall of the upper tube in the front frame, the grip is synchronized with the upper tube of the front frame, and an elastic element is pressed before The upper tube has a central shaft tube and an upper shaft tube at each end of the crossbar, and a positioning groove is provided on the outer periphery of the upper shaft tube. According to this, the upper tube of the front frame is elasticized by the elastic element, and the convex strip is snapped into the upper shaft tube. In the positioning groove, the tripod is deployed and positioned from both ends of the crossbar. When the upper grip grip is linked with the protrusion of the upper tube of the front frame to move away from the positioning groove of the upper shaft tube, the tripod can be turned according to the central shaft tube. Close up.本創作係提供一種助行器之收折結構改良,主要包含有兩腳架結合一橫桿及兩組收折機構作折收,腳架有一前架、一握桿及一後架,前架與橫桿兩端之間具有收折機構,握桿下方有一握把,於前架內有一前架上管內壁有一凸條,握把與前架上管同步連動,有一彈性元件受壓前架上管,於橫桿兩端各有一中心軸管及一上軸管,上軸管外周有一定位凹槽;據此,前架上管受彈性元件彈力,將凸條卡入上軸管之定位凹槽內,使腳架自橫桿兩端展開定位,當上壓握把連動前架上管之凸條上移脫離上軸管之定位凹槽,則可依中心軸管轉折腳架作收折。
