[0027] In a preferred embodiment, a movable block 403 is fixedly connected to both the front and back sides of the top of the first gripper 401.

The electric rod base 502 is fixed in the second circular hole 402, and when the first clamping hand 401 moves, it will drive the electric rod base 502 to move together.

[0030] In a preferred embodiment, the first fixing component 1 includes a left fixing seat 101. A limiting groove 104 is formed on one side of the left fixing seat 101, and a movable groove 103 is formed on the inner side of the left fixing seat 101.

A first circular hole 105 is fixedly connected to the top of the left fixing seat 101, and the top of the second hydraulic rod 303 is fixedly connected to the first circular hole 105.

[0032] In a preferred embodiment, the width and height of the movable block 403 are both matched with the width and thickness tolerances of the movable square groove 3043, and the inner diameter of the movable circular groove 3042 is matched with the outer diameter tolerance of the circular shaft 405. Then, the operator adjusts the position of the first clamping hand 401 by moving the limiting block 404, so that the first clamping hand 401 moves to the other side of the top of the corrugated sheet to be pulled and corrected in the transformer. When the limiting block 404 moves, the movable block 403 moves in the movable square groove 3043, and the circular shaft 405 moves in the movable circular groove 3042.

[0033] In a preferred embodiment, the height of the inner side of the movable groove 103 is in tolerance with the height of the limiting block 204, and the height of the movable rod 203 is in tolerance with the height of the inner side of the limiting groove 104; the hydraulic cylinder 301 is activated to drive the first hydraulic rod 302 to move, thereby moving the connecting plate 305. During this process, the limiting block 204 and the movable rod 203 move in the movable groove 103.

[0034] The working principle of this utility model is as follows: When correcting the corrugated sheet inside the transformer, the distance between the bottom of the left fixed seat 101 and the right fixed seat 201 is first adjusted according to the outer dimensions of the transformer. The hydraulic cylinder 301 is started to drive the first hydraulic rod 302 to move, which in turn drives the connecting plate 305 to move. During this process, the limiting block 204 and the movable rod 203 move in the movable groove 103, and the right fixed seat 201 and the left fixed seat 101 move away from each other to expand. The first limiting plate 102 and the second limiting plate 202 limit the top of the transformer.

[0035] Then, the operator adjusts the position of the first clamping hand 401 by moving the limit block 404, so that the first clamping hand 401 moves to the other side of the top of the corrugated sheet to be pulled and corrected in the transformer. The electric rod base 502 is fixed in the second circular hole 402. When the first clamping hand 401 moves, it will drive the electric rod base 502 to move together. Then, according to the thickness of the corrugated sheet, the electric rod base 502 is driven to move the electric push rod 503. The electric push rod 503 pushes the second clamping hand 501 to move, thereby changing the position of the first clamping hand 401 and the second clamping hand 501. The distance between the two hands is adjusted to accommodate different corrugated sheet thicknesses. The second gripper 501 is located on one side of the top of the corrugated sheet to be pulled and corrected. The hydraulic cylinder 301 is activated to drive the second hydraulic rod 303 to move, so that the height of the first gripper 401 and the second gripper 501 decreases synchronously to the top of the corrugated sheet to be pulled and corrected. The distance between the first gripper 401 and the second gripper 501 can be finely adjusted by the displacement of the electric push rod 503 to achieve stable clamping of the corrugated sheet. Then, the second hydraulic rod 303 is pulled to modify the degree of deformation of the corrugated sheet and extend its service life.
