| 摘要 |
The invention relates to a tube-cutting tool of the type that includes supporting rollers in a curved head and a facing circular cutting blade, and is provided with an adjusting device in the head, between the supporting rollers and the blade, said adjusting device substantially consisting of a parallel guide disk that can rotate about a transverse axis and can, in turn, be manually moved according to the diameter of the tube to be cut. The adjusting device allows the cutting to be optimised easily, rapidly and intuitively, manually modifying the position of the guide disk such that the guide disk moves into different positions according to the different diameters of the tubes, in such a way that the latter remain in contact or substantially in contact with the supporting rollers during the entire cutting process, without the cutting axis moving or deformations being produced on the tube. |
