In operation, support 20 and clamp 30 are placed in corresponding positions inside and outside conduit 10, respectively, and second clamp 32 is used as a fulcrum to correct conduit 10. Specifically, support 20 is inserted into conduit 10 and moved to a position where correction is required, and support 20 has elasticity, can be bent along with bending of conduit 10, and can be removed from bent conduit 10 by tensile deformation after bending.

At the same time, support 20 should be able to process the inside of conduit 10 to avoid flattening of conduit 10 during bending. The support 20 is therefore made of a resilient material that is stretchable, preferably a tension spring. The spring wire diameter of the support part 20 is preferably 0.2-0.4mm, preferably 0.3 mm; the outer diameter of the conduit is 2-8mm, preferably 3mm smaller than the inner diameter of the conduit 10; meanwhile, the length of the extension spring is larger than 10cm in a natural state, the extension spring is not limited in length and can be longer than the length of the line pipe 10, and the extension spring is convenient to insert and extract.

In this embodiment, in order to facilitate bending of the line pipe 10, the correction device is provided with a clamping portion 30, one end of the clamping portion 30 is provided with a first clamping member 31, the other end of the clamping portion is provided with a second clamping member 32, the middle of the clamping portion is connected with a connecting rod 33 by a steel pipe with a certain length, the first clamping member 31 is fixedly connected with the connecting rod 33, and the second clamping member 32 is detachably connected with the connecting rod 33, that is, the first clamping member 31 is positioned at the upper end of the clamping portion 30 and is of an annular structure, and is welded by a galvanized circular steel pipe with the thickness of 6mm, and the diameter of the inner wall of the first clamping member 31 is the same as that of the inner wall of the second clamping member 32, or smaller than that of the second clamping member 32, as long as the upper end face of the support portion 20 can be lifted; the second clamping piece 32 is positioned at the lower end of the clamping part 30, is of a cylinder structure with the height of 50mm and is welded by a DN25 galvanized steel pipe; the connecting rod 33 is a long rod, the length of which is greater than that of the second clamping piece 32 and greater than that of the line pipe 10, and the long rod is formed by welding a 6mm galvanized round steel pipe. When the spool 10 is used, the first clamping piece 31 and the second clamping piece 32 are respectively sleeved on the spool 10, and the spool 10 is corrected by taking the second clamping piece 32 as a fulcrum and the first clamping piece 31 as a handle. Second retaining member 32 has a length of 30-34mm, preferably 32mm, and an inner diameter 2-4mm greater than the outer diameter of conduit 10.

When the conduit 10 to be straightened is long, it is necessary to prepare the support 20 to extend the spring corresponding to the length thereof, which results in a very laborious insertion process and an inconvenient operation. Therefore, as shown in fig. 3, providing first magnetic member 21 on the inner wall surface of support 20 at the position close to the bend on the side of conduit 10 facilitates entry into conduit 10 or removal from conduit 10 with the body of support 20; the outer wall surface in second holder 32 is equipped with second magnetic member 34 that sets up with first magnetic member 21 opposite position cover, and first magnetic member 21 and second magnetic member 34 have mutual attraction, utilizes the magnetic attraction of first magnetic member 21 and second magnetic member 34, guides the first magnetic member 21 of placing in spool 10 through removing the second magnetic member 34 of locating the spool 10 outside, and makes supporting part 20 move to its required position in spool 10.

Meanwhile, in order to prevent the problem that the support 20 cannot be taken out after the pipe 10 is bent, the upper end of the support 20 is connected with the first clamping member 31 through the flexible member 40 so that the support 20 can be taken out by pulling the flexible member 40 after the straightening, and preferably, the flexible member 40 is a drawable connecting member having a certain strength such as a rope or a steel wire.

The use of the conduit straightening device is described in further detail below:

first, the support 20 is placed in the conduit 10 to be straightened while the second clamp 32 is fitted over the conduit 10. Then, adjusting the relative position of the first magnetic member 21 in the conduit 10 and the second magnetic member 34 outside the conduit 10 to enable the first magnetic member and the second magnetic member to be attracted; thereafter, the second clamp 32 is moved to a desired position, and the support 20 is moved to a corresponding position by a magnetic attraction force.

Sleeving the first clamping member 31 on the conduit 10 and installing and connecting the other end thereof to the second clamping member 32; then, the portion of the conduit 10 where correction is required is heated.

Straightening the conduit 10: the correction of the wire tube 10 is performed by moving the position of the conveying and clamping part 30 close to the first clamping member 31 with the second clamping member 32 as a fulcrum.
