The invention discloses a telescopic operation handle. The telescopic operation handle includes a telescopic knot, a rotation knot, a spring blocking mechanism and a mounting base, wherein the rotation knot is hinged in the mounting base, the spring blocking mechanism is mounted on the rotation knot, the telescopic knot is movably mounted in the rotation knot through the spring blocking mechanism,and the telescopic knot does axial motion in the rotation knot along the rotation knot. The telescopic operation handle is advantaged in that length of the telescopic operation handle can be adjustedin the operation process, a variable operation angle is flexible, the telescopic operation handle not only has properties of small occupation space during withdrawal and operation laborsaving duringstretching, but also blocking is reliable, and the relatively large operating force can be borne.
