[0023] As Figure 5 shown, in the embodiment, connecting shaft 6 includes the optical shaft part 602 in the middle and the screw rod part 601 separately arranged on both sides of the optical shaft part 602, wherein the screw rod part 601 of one side of the optical shaft part 602 is in sequence through support plate hole 402 on support plate 4 and first through hole on first clamping frame 5 and is connected with the nut threadedly, and the screw rod part 601 on the other side is through second through hole on second clamping frame 7 and is connected with the nut threadedly, and the nut on both sides guarantees that support plate 4 and the upper yoke of the core 1 are clamped and fixed.The length L of the optical shaft part 602 is equal to the thickness of the upper yoke of the core 1, so that on the one hand can avoid drilling the threaded hole on the upper yoke of the core 1, and on the other hand is also convenient to adjust when installing, wherein the screw rod part 601 of one side of connecting shaft 6 is in sequence through the upper yoke of the core 6, support plate 4 and first clamping frame 5 and is connected with the nut, then operating personnel can rotate connecting shaft 6 to observe whether the rear end of optical shaft part 602 is flush with the rear side of the upper yoke of the core 1, and after flush, second clamping frame 7 is installed.

[0024] In addition, when the thickness of the core yoke 1 changes, the connecting shaft 6 can be replaced to ensure that the length L of the optical axis portion 602 matches the thickness of the core yoke 1, while ensuring that the lengths of the screw rod portions 601 on both sides meet the clamping connection requirements. For example, when the thickness of the core yoke 1 is 100mm, a connecting shaft 6 with an L of 100mm and a total length of 600mm is used; when the total thickness of the core yoke 1 is 300mm, a connecting shaft 6 with an L of 300mm and a total length of 800mm is used; when the thickness of the core yoke 1 is 700mm, a connecting shaft 6 with an L of 700mm and a total length of 1200mm is used. In any case, the lengths of the screw rod portions 601 on both sides are 250mm to meet the clamping connection requirements.

[0025] like Figures 1 to 4 As shown, in this embodiment, the first clamping frame 5 and the second clamping frame 7 are both channel steel structures, and the first clamping frame 5 and the second clamping frame 7 can be replaced with channel steels of appropriate length specifications according to the width of the core upper yoke 1.
