A ratchet type bending spanner comprises a handle; a holding portion at one end of the handle; a bending tubular portion at another end of the handle; an engaging unit having a part rotatable installed in the bending tubular portion; and the other part of the engaging unit being protruded from the bending tubular portion for engaging with a sleeve; the part in the bending tubular portion being formed with a ratchet portion which is engaged to a buckling block; and the buckling block being restorable elastically. A switch is installed in the bending tubular portion for controlling the shift of a position of the engaging block so as to form a bidirectional ratchet type bending spanner. The handle is a soft handle with a stop edge.
