The upper part of the spacing/adjusting device is connected with a floating guide column through a spring. The outer diameter of the floating guide column is smaller than the inner diameter of the base. When the spring is stationary, one end of the floating guide column is provided in the base, and the other end extends out of the base. A downward end of the opening of the corrugated pipe with a bottom is sleeved on the floating guide column, and the bottom contacts with the upper end of the floating guide column. An upper gland is also provided above the bottom. The clamp provided by the utility model realizes whole-process guiding while the inner diameter of the corrugated pipe is used as a standard. The spacing/adjusting device can set a maximal compression amount for preventing excessive compression of the corrugated pipe. Not only is axis bending prevented, but also radial staggering of the inner crinkle of the corrugated pipe is restricted, so that an axisymmetric geometry of the corrugated pipe is ensured, thereby ensuring smooth carrying-out of mass production. After the form of the clamp provided by the utility model is adopted, correction effect on the corrugated pipe is remarkably improved.
