[0005] The pull tab 1 is a stainless steel long strip sheet; a pull hole 101 is punched out at the upper part of the pull tab, and the length and width dimensions are greater than the diameter of a finger, so as to facilitate the insertion of a finger; a part of the sheet punched out at the pull hole is bent downward to form an upper edge 102, and the height of the upper edge is equal to the thickness of the magnet 2; a gap is punched out at the lower part of the pull tab in the same direction as the upper part, and a part of the sheet punched out is bent upward to form a lower edge 103, and the height of the lower edge is equal to the thickness of the magnet 2; the two remaining sheets after punching the gap at the lower part form a blocking strip 104.

[0006] The magnet 2 is a square strong magnet, which is glued between the upper edge 102 and the lower edge 103 on the surface of the pull tab 1; the height of the magnet is equal to the distance between the upper edge 102 and the lower edge 103 of the pull tab 1, and the thickness of the magnet is equal to the thickness of the sealing gasket 4.

[0007] Further, in order to facilitate the selection of the magnetic positioning tool corresponding to the thickness of the sealing gasket 4 during use, a thickness mark 105 is marked on the other side of the pull tab 1 with the magnet 2.

[0008] Compared with the existing background technology, the above at least one technical scheme adopted by one or more embodiments of the present specification can achieve the following beneficial effects:

[0009] First, when the flange installs the sealing gasket, through the magnetic positioning tool, the sealing gasket can be conveniently positioned and fixed on the carbon steel plane flange, and the sealing gasket is avoided to be mispositioned and dropped;Second, the magnetic positioning tool is not limited by the material of the sealing gasket, and the metal, nonmetal and other materials can be conveniently positioned;Finally, the magnetic positioning tool is simple in structure, small in size, low in manufacturing cost and convenient to carry.
