[0022] In the present invention, the horizontal frame 1 is used as the main body of the device. When in use, the adjustment member frames on both sides are first started to rise, and at this time, the two movable legs 4 are used for support. The universal wheels 9 at the bottom can be used to push the entire device to the coil, and then the spacing adjustment member 7 is started to adjust the width according to the horizontal size of the coil to adapt to the coil size, so that the side clamping mechanisms 6 on both sides are aligned with the center holes on both sides of the coil respectively, and then the spacing adjustment member 7 is started to call back, so that the two movable legs 4 are brought together, so that the clamping mechanisms 6 on both sides are clamped into the coil, and then the side clamping mechanisms 6 clamp the coil, and the clamping is completed at this time, and then the device is started. The vertical driving rail 5 moves vertically to drive the two side clamping mechanisms 6 to rise, so as to lift the coil. When it needs to be moved after lifting, the two adjusting frames 2 are started to retract upward and separate from the ground to release the positioning. Then the universal wheels 9 can be used to move it, thereby achieving an efficient and stable lifting effect of the device.
