[0005] Furthermore, the power source is a battery fixedly connected to the straight rod.

[0006] Furthermore, the straight and curved rods are connected by a universal damping ball joint.

[0007] Furthermore, a portion of the conductor is located inside the straight rod, the curved rod, and the insert rod.

[0008] Furthermore, a non-slip handle is fixedly connected to the end of the straight rod away from the curved rod.

[0009] Furthermore, it also includes a lever, with a lifting ring 1 fixedly connected to the middle of the lever for connection with the overhead crane, a lifting ring 2 fixedly connected to one end of the lever for connection with the lifting belt, and a lifting ring 3 fixedly connected to the other end; the lifting ring 3 is detachably connected to a counterweight.

[0010] Furthermore, the overhead crane includes overhead crane ropes and overhead crane hooks.

[0011] This invention, by setting up an auxiliary adjustment device, can replace manual operation when installing and disassembling steel rolls, thereby avoiding the problem of workers directly adjusting steel rolls by hand, which can easily cause hand injuries or crushing.

[0012] This invention features straight and curved rods to maintain a certain distance between the worker and the steel roll; and by using an electromagnet, it can attract and release the steel roll by switching the power on and off.

[0013] This invention, by setting up a lever, allows for the use of a crane hook to connect to a lever when there is a cover above the cold rolling mill and the crane hook cannot reach it. One end of the lever extends under the cover to connect to the steel roll. Attached Figure Description
