The present invention relates to indoor and outdoor crutches which can be used indoors and outdoors. Each of the indoor and outdoor crutches of the present invention comprises: a support having coupling projections formed to downwardly protrude from both ends at the bottom thereof and having a coupling groove formed to be downwardly opened between the coupling projections; a leg unit having one end coupled with an indoor adhering part, having the other end coupled with an outdoor adhering unit, and coupled with the inside of the coupling groove to be able to be rotated; and a pressing member coupled with the coupling projection to fix the rotation of the leg unit. The coupling projection consists of a first coupling projection and a second coupling projection separated from each other. The pressing member comprises: a fixed shaft penetrating through the coupling groove, coupling projection, and leg unit; a cam lever coupled with one end of the fixed shaft and adhered on the outer circumferential surface of the first coupling projection; and a fixing unit coupled with the other end of the fixed shaft and adhered on the outer circumferential surface of the second coupling projection. The leg unit in which the coupling projection is inserted and disposed in the coupling groove is pressed and fixed by the rotation of the cam lever. |
