A stripper, which can serve as a wrench, includes a body, an exchangeable tool holder, a blade, a fixing member and an elastic element. The body includes a hole and a notch used for accommodating a coaxial terminal. The exchangeable tool holder is disposed in the hole, and the exchangeable tool holder has a first side comprising a recess. The blade is connected with the exchangeable tool holder, and at least one portion of the blade protrudes out of the recess. The fixing member is movably connected with the body and includes a concave located in the hole to correspond to the recess and to form an opening along with the recess. The opening is used for accommodating a wire. The elastic element is connected with the fixing member to provide an elastic force to the fixing member.
