The steel pipe is used for manufacturing the building structure net rack, the supporting column and the mechanical support, so that the weight can be reduced, the metal can be saved by 20-40%, and the industrialized mechanized construction can be realized. The steel pipe is used for manufacturing the highway bridge, so that steel can be saved, the construction is simplified, the area of a coating protective layer can be greatly reduced, and the investment and the maintenance cost are saved.

At present, in the building industry, steel pipes and square pipes are widely used, but according to different application environments and purposes, steel pipes and square pipes with different sizes are needed, so that the steel pipes and the square pipes need to be fixedly cut, but when the steel pipes are cut on the existing site, one person needs to fix and one person needs to cut, manpower is wasted, and manual fixation is unstable, so that the effect of cutting openings is uneven.

CN 208663132U discloses a fixing device for cutting a building steel pipe, which comprises a bottom plate and the like; the middle of the bottom plate is provided with a through hole, the left side and the right side of the bottom plate are symmetrically provided with supporting legs, the left side and the right side of the top of the bottom plate are symmetrically provided with supporting rods, a top plate is arranged between the top ends of the supporting rods on the left side and the right side, the left side and the right side of the top plate are provided with guide holes, and an n-shaped rod is. An operator presses the n-shaped rod to move downwards, so that the arc-shaped clamping plates on the left side and the right side can fix the steel pipe, and the operator can conveniently cut the steel pipe. But it is limited only to the fixed of steel pipe, can not realize fixed to square pipe, has certain use limitation, and the structure is complicated, and the cost is higher.
