Disclosed is a manual stepping clamp, comprising a retainer structure, a cover board structure, an advancing structure and a clamp handle structure. The utility model is characterized in that the clamp head is in a coaxial structure and a shift stepping structure is introduced into the area between the clamp head and the advancing structure; the coaxial clamp head structure and the cover board structure is connected through a pin roll; the shift stepping structure and the clamp handle are connected by a pin roll through the cover board structure and so do the coaxial clamp head structure and the retainer structure; the shift gear of the shift stepping structure meshes with the wheel teeth of the coaxial clamp head structure. The advantages of the utility model lie in that: firstly, the force positioning of the coaxial clamp head structure is accurate and shift stepping is realized through the shift stepping structure, thus clamping quickly and saving labour and time; secondly, the utility model has multiple uses such as clamping, cutting and snipping; thirdly, the clamp handle is easy to apply force, convenient to use and easy to operate.
