A crutch chair comprises a main rod having a holding end, a riding unit, a bottom limiting unit, a supporting unit, and a linkage unit. The linkage unit comprises a connecting end connected to a seat board of the riding unit and a driving portion connected to the supporting unit. When the seat board of the riding unit is operated to swing from a first position where the seat board of the riding unit is juxtaposed and abutting the holding end of the main rod in a direction of getting away from the holding end of the main rod to a second position, the supporting unit is driven, via the linkage unit, from a folded state to a unfolded state. When the supporting unit is in the unfolded state, the seat board of the riding unit forms an included angle with respect to the main rod and allows for sitting thereon, thereby attaining the purpose of multiple uses.一種拐杖椅,包含一主桿、一乘坐單元、一底限單元、一支撐單元及一連桿單元,該連桿單元具有一連接於該乘坐單元一坐板的連接端及一連接於該支撐單元的帶動部,當操作該坐板由一併列靠合於該主桿的一握持端的第一位置朝遠離於該握持端擺動至一第二位置時,透過該連桿單元可連動該支撐單元由一收合狀態操作成一展開狀態,該支撐單元在展開狀態時,該坐板與該主桿形成一夾角且可供坐置,可達到多用途使用目的。1‧‧‧主桿11‧‧‧握持端12‧‧‧支撐端142‧‧‧凹槽143‧‧‧凹槽15‧‧‧下滑座151‧‧‧連動桿152‧‧‧穿槽2‧‧‧乘坐單元21‧‧‧椅固座22‧‧‧坐板221‧‧‧扣孔3‧‧‧底限單元31‧‧‧固定座32‧‧‧下滑動座33‧‧‧上滑動座34‧‧‧拉持彈性件4‧‧‧支撐單元41‧‧‧支撐桿42‧‧‧輔助桿43‧‧‧上桿件433‧‧‧樞接端部434‧‧‧活動端部44‧‧‧下桿件441‧‧‧底端部5‧‧‧連桿單元51‧‧‧第一連桿52‧‧‧第二連桿521‧‧‧帶動部
