Magnet yoke magnetic pole improvement device

The utility model discloses a magnet yoke magnetic pole improvement device, which relates to the technical field of nondestructive testing equipment and comprises a magnet yoke flaw detector, connecting blocks are arranged on two sides of the magnet yoke flaw detector, the other end of each connecting block is rotatably connected with a magnetic pole, a fixing block is arranged at the top end of the magnetic pole, and a contact mechanism is arranged on the fixing block. The contact mechanism is used for performing contact detection on the to-be-detected steel pipe; the contact mechanism comprises a contact assembly and a sliding assembly. By arranging the contact mechanism, when the device is used for detecting a steel pipe, the top ends of a plurality of groups of closely arranged contact blocks are arranged in a semicircular arc shape, so that the contact area with the steel pipe is increased, the steel pipe can be in full contact with a magnetic pole, the magnetic field intensity is increased, and the dete
