[0032] When wiring the transformer, first pass the power cord 3 through the terminal box 4, then rotate the adjustment block 5 to drive the bidirectional threaded rod 6 to rotate, thereby driving the moving seat 7 to move toward the adjacent side of the outer wall of the bidirectional threaded rod 6, and drive the clamping block 9 to clamp and fix the power cord 3 through the connecting rod 8. During the clamping process, the curvature of the surface of the power cord 3 will cause the fixing piece 10 to slide in the clamping block 9 to squeeze the spring 11, so that the fixing piece 10 fits the surface of the power cord 3 to improve the fixing effect.

[0033] The driving assembly includes a servo motor 14 , which is fixedly connected to the top of the mounting plate 13 , and a threaded rod 15 is fixedly connected to the output end of the servo motor 14 , and a nut pair 16 is passed through and threadedly connected to the outer ring of the threaded rod 15 .

[0034] The servo motor 14 is started to drive the threaded rod 15 to rotate, so that the nut pair 16 moves on the outer wall of the threaded rod 15 .

[0035] Embodiment 2: A guide rod 17 is fixedly connected to the top of the mounting plate 13, and a connecting block 18 is penetrated and slidably connected to the outer ring of the guide rod 17, a blowing plate 19 is fixedly connected between the nut pair 16 and the adjacent side of the connecting block 18, and an evenly distributed air outlet duct 20 is penetrated and fixedly connected to the rear side of the blowing plate 19, a fan 21 is fixedly connected to the top of the mounting plate 13, a hose 22 is fixedly connected to the rear side of the fan 21, and the hose 22 penetrates the bottom of the blowing plate 19 and is fixedly connected, the threaded rod 15 and the top of the outer ring of the guide rod 17 are penetrated and fixedly connected to the limiting ring 23, and two connecting parts 24 are fixedly connected to the front and rear sides of the shell 1.

During the clamping process, the curvature of the surface of the power cord 3 will cause the fixing piece 10 to slide in the clamping block 9 to squeeze the spring 11, so that the fixing piece 10 fits the surface of the power cord 3 to improve the fixing effect. When the temperature of the transformer body 2 is too high during operation, start the fan 21 on the mounting plate 13, and convey the wind to the blowing plate 19 through the hose 22, and then blow it out from the air outlet 20 to cool the transformer body 2. At the same time, start the servo motor 14 to drive the threaded rod 15 to rotate, so that the nut pair 16 moves on the outer wall of the threaded rod 15, and the servo motor 14 drives the threaded rod 15 to rotate forward and reverse, so that the nut pair 16 and the connecting block 18 drive the blowing plate 19 to move up and down repeatedly, so as to achieve uniform cooling of the transformer body 2.
