[0021] See also Figure 1-Figure 3 , an iron-nickel-based nanocrystalline racetrack magnetic core shown in the figure comprises a nanocrystalline magnetic core 1, a fixing plate 21 is arranged on the peripheral side of the nanocrystalline magnetic core 1, an extension component 7 is arranged on the top of the fixing plate 21, a lifting component 4 is arranged on one side of the fixing plate 21, the fixing plate 21 is connected to the fixing plate 2 22 through the lifting component 4, a rack 5 is slidably connected inside the top of the fixing plate 21, the fixing plate 21 is connected to the fixing plate 3 23 through the rack 5, and one side of the fixing plate 3 23 is connected to the fixing plate 4 24 through the lifting component 4;

[0022] A slide bar 8 is fixedly installed at the bottom of the fixing plate 1 21, and the slide bar 8 is slidably connected to the fixing plate 2 22. A slide bar 8 is also fixedly installed at the bottom of the fixing plate 3 23, and the slide bar 8 is slidably connected to the fixing plate 4 24.

[0023] The second fixing plate 22 is slidably connected with the connecting rod 6, the connecting rod 6 is fixed to one side of the bottom of the fourth fixing plate 24, the rack 5 is fixed to one side of the top of the third fixing plate 23, and bolt holes 3 are provided on the first fixing plate 21, the second fixing plate 22, the third fixing plate 23 and the fourth fixing plate 24;

[0024] The lifting assembly 4 includes a sleeve 41, the top of the sleeve 41 is rotatably connected to a rotating cylinder 412, the rotating cylinder 412 is spirally connected to a threaded rod 42, the top of the threaded rod 42 is rotatably connected to a connecting plate 43, and the connecting plate 43 is fixed on a fixed plate 21;

[0025] The top annular array of the sleeve 41 has several limit plates 411, the inner wall of the sleeve 41 is provided with a rotating groove 413, the rotating cylinder 412 is provided with a slideway 4121, the slideway 4121 is slidably connected with a limit ring 44, a slider 441 is installed on the inner wall of the limit ring 44, the slider 441 is installed in the slideway 4121, the outer annular array of the limit ring 44 has limit blocks 442, the limit blocks 442 can be inserted between the limit plates 411, and the bottom of the rotating cylinder 412 is provided with a rotating ring 4122, and the rotating ring 4122 is installed in the rotating groove 413.

[0026] In this solution, the fixing plate 1 21, the fixing plate 22, the fixing plate 3 23 and the fixing plate 4 24 are arranged on the peripheral side of the nanocrystalline magnetic core 1 for fixing the nanocrystalline magnetic core 1, and the bolt holes 3 arranged on each fixing plate can be used to install bolts, so as to facilitate the combined installation of multiple nanocrystalline magnetic cores 1. When installing nanocrystalline magnetic cores 1 of different sizes, the lifting assembly 4 and the extension assembly 7 need to be adjusted;

[0027] In a normal state, the limit block 442 on the limit ring 44 is inserted into the limit plate 411. The limit plate 411 can prevent the limit ring 44 and the rotating cylinder 412 from rotating, thereby preventing the height distance between the fixed plates from changing. When the lifting assembly 4 needs to be adjusted, the limit ring 44 is moved upward along the slideway 4121, so that the limit block 442 on the limit ring 44 is separated from the limit plate 411, so that the limit ring 44 and the rotating cylinder 412 can rotate along the rotating groove 413. During the rotation of the rotating cylinder 412, the threaded rod 42 is continuously extended and raised, so that the fixed plate 1 21 moves upward along the slide rod 8, so that the distance between the fixed plate 1 21 and the fixed plate 2 22 becomes larger, so that the fixed plates can accommodate a wider nanocrystalline magnetic core 1.

[0028] For further information, see Figure 4 The extension assembly 7 includes a moving plate 71, which is slidably mounted in the moving groove 75. A fixing member 74 is fixedly connected to the bottom of the moving plate 71. The fixing member 74 is arranged in the sliding groove 72. A spring 73 is installed on the inner wall of the sliding groove 72. The fixing member 74 is connected to the inner wall of the sliding groove 72 through the spring 73. The bottom of the fixing member 74 is in an inverted triangle shape, and the fixing member 74 can mesh with the rack 5.

[0029] Specifically, the extension component 7 can lengthen the length between the fixed plates. During adjustment, the movable plate 71 is moved along the movable groove 75 so that the fixing piece 74 at the bottom of the movable plate 71 can squeeze the spring 73, and at the same time, the fixing piece 74 is retracted into the interior of the sliding groove 72, so that the rack 5 can be extended by moving in the fixed plate 1 21, so that the fixed plate 3 23 together with the fixed plate 4 24 are moved along the connecting rod 6, so that the length between the fixed plates is extended to facilitate adaptation to nanocrystalline cores 1 of different lengths. After the extension is completed, the spring 73 is used to push the fixing piece 74 into the rack 5 to limit and fix the rack 5 to prevent the length between the fixed plates from changing. The lifting component 4 and the extension component 7 can be used to adjust the distance between the fixed plates so as to adapt to nanocrystalline cores 1 of different sizes, thereby ensuring the stability of the nanocrystalline core 1 during use.
