Samarium-cobalt strong-magnet iron rod

A samarium-cobalt strong-magnet iron rod comprises a stainless steel mounting plate (1) and at least two magnetic rods (2). The mounting plate (1) is provided with through holes (1.1) corresponding to the magnetic rods (2) one by one, the magnetic rods (2) penetrate the through holes (1.1) and in slide fit with the through holes (1.1), the upper portions of the magnetic rods (2) are provided with a limit mechanism used for preventing the magnetic rods (2) from sliding off the mounting plate (1), and the limit mechanism comprises ring blocks (6) circumferentially arranged on the outer wall of the upper ends of the magnetic rods (2), and the outer diameter of each ring block (6) is larger than the diameter of each through hole (1.1). The upper ends of the magnetic rods (2) are provided with a linkage mechanism sliding along with the magnetic rods (2), the linkage mechanism comprises a connecting fixing block (7) fixedly connected with the magnetic rods (2) respectively, and a handle (8) is arranged on the conne
