The invention discloses an intelligent magnetic flux leakage internal detection instrument suitable for pipelines with various diameters. The instrument comprises a sealing joint assembly and a magnetic flux leakage joint assembly, the multiple groups of sealing joint assemblies are flexibly connected, the backmost sealing joint assembly is movably connected with the magnetic leakage joint assembly, and each group of sealing joint assembly comprises a sealing joint framework, a folding leather cup and a leather cup supporting assembly; the multiple sets of leather cup supporting assemblies are evenly distributed in the circumferential direction and drive the folding type leather cups to swing in the radial direction of the planes of the folding type leather cups, so that the folding type leather cups elastically press and seal the inner wall of the pipeline. The magnetic flux leakage joint assembly comprises a magnetic flux leakage joint supporting assembly, an electronic bag and a magnetic circuit detection
