The double-threaded rod 32 is rotatably connected to the inner side of the multi-shaped limiting groove 22 through a bearing. The opening shape of the ladder groove 24 is the same as the shape of the ladder slide 37. There are two ladder grooves 24. The ladder slide 37 is slidably connected to the inner side of the ladder groove 24, which plays a role in limiting the rotation of the double-threaded rod 32, and at the same time facilitates the ear seat of the movable square plate 38 to be embedded in the multi-shaped limiting groove 22.

[0033] Workflow: During the use of the device, the internal power supply is energized, which drives the connection shell 1 and the limit outer shell assembly 2 to move, achieving the function of transporting the transformer body 6. At this time, the upper end of the convex plate installed at the bottom of the transformer body 6 is in contact with the bottom end of the bottom shell plate 4. A sealing ring is installed at the upper end of the convex plate of the transformer body 6, which plays a role in sealing between the bottom shell plate 4 and the transformer body 6, preventing dust from entering through the inside of the movable groove 5.

The double threaded rod 32 drives the movable square plate 38 and the support slide plate 33 connected by spiral connection on the outside to move. According to the shape of the double threaded rod 32, the movable square plate 38 and the support slide plate 33 move in opposite directions at the same time. One end of the movable square plate 38 slides inside the polygonal limit groove 22, and at the same time, the movable square plate 38 is slidably connected to the frame shell 21 through the ladder slide bar 37. According to the shapes of the ladder slide bar 37 and the ladder groove 24, it plays a role in limiting the ladder slide bar 37. The support slide plate 33 is slidably connected to the inside of the portal groove 23 through the limit slide bar 34, playing a role in limiting the movement of the support slide plate 33. At this time, the first damper 35 and the universal wheel 36 are received inside the portal groove 23. The convex block at the lower end of the transformer body 6 gradually moves away from the bottom shell plate 4, and the body of the transformer body 6 moves downward.
