The working principle is as follows: when the utility model is used, firstly, the box 3 is placed, one side of the box is opened to be provided with a box door, a steel coil is sleeved on the round bar 39, then the handle 5 arranged on four sides of the box 3 is screwed to rotate the thread cylinder 4 on the side wall of the box 3, because the cross sections of the slider 8 and the slide bar 9 are square, the thread cylinder 4 drives the slider 8 and the slide bar 9 to synchronously rotate, at the moment, under the arrangement of the spring 6 and the guide bar 7, the arc-shaped clamping plate 10 is close to the steel coil until the steel coil is tightly attached, then one end of the steel coil passes through the first through hole 12 and the second through hole 16 to be connected with the next procedure, and the steel coil plates are arranged between the second moving block 33 and the second clamping block 34 and between the first moving block 21 and the first clamping block 25, as shown in the state of figure 1, then the first motor 37 and the second motor 38 are started to simultaneously operate, and in the operation process of the second motor 38, the output end drives the first cam 13 to rotate, and in the process of the rotation of the first cam 13, the first cam 13 pushes the first sliding plate 15 in a contact manner, so that the first sliding plate 15 drives the second pushing block 35 to approach the second clamping block 34, and at this time, the elastic force of the second spring 28 is smaller than that of the first spring 19, so that the first sliding plate 15 moves the second pushing block 35 upwards while driving the second clamping block 34, and further the second clamping block 34 and the second moving block 33 tighten the steel coil, then the first cam 13 continues to push the first sliding plate 15 while rotating, further the first sliding plate 15 pushes the second clamping block 34 and the second moving block 33 to move synchronously, and at this time, the steel coil clamped between the second clamping block 34 and the second moving block 33 moves to one side synchronously, at this time, the steel coil pulled on the round rod 39 rotates, and in the process of the rotation of the steel coil, through the arrangement of the spring 6, the plurality of arc-shaped clamping plates 10 are always attached to the steel coil, so that the steel coil is effectively fixed, the rotation looseness of the steel coil caused by inertia is avoided, meanwhile, the first motor 37 operates, the output end drives the second cam 36 to rotate, the included angle between the second cam 36 and the first cam 13 is 60 degrees, when the first cam 13 pushes the first sliding plate 15 to move to the maximum displacement, the second cam 36 rotates to push the second sliding plate 32 to be just contacted with the first clamping block 25, and then the steel coil is effectively clamped, at the time, as shown in a state shown in fig. 3, the first cam 13 and the second cam 36 continue to rotate, and when the second cam 36 rotates, the second sliding plate 32 continues to be pushed, so that the first pushing block 31 pushes the first clamping block 25 to move upwards, and further the first clamping block 25 and the first moving block 21 clamp the steel coil, then, the second sliding plate 32 is pushed continuously, so that the first clamping block 25 moves synchronously with the first moving block 21 and the clamped rolled steel plate, meanwhile, the thrust generated by the rotation of the first cam 13 to the first sliding plate 15 is gradually reduced, then the second moving block 33, the second clamping block 34 and the first sliding plate 15 are pushed to move towards the side of the supporting plate 14 under the arrangement of the first spring 19 and the second spring 28, and the clamping force to the rolled steel plate is gradually reduced in the process of moving the second moving block 33 and the second clamping block 34 until the first sliding plate 15 moves back to the original position, the second pushing block 35 completely loses the thrust to the second clamping block 34, at the moment, the second clamping block 34 is moved back to the original state under the arrangement of the tension spring 23, so that the second moving block 33 and the second clamping block 34 move towards opposite directions in the process of moving the first clamping block 25 and the first moving block 21 and the clamped rolled steel plate to one side, in addition, in the process that the second moving block 33 and the second clamping block 34 move, the clamping force on the rolled steel plate is gradually reduced, so that the second moving block 33 and the second clamping block 34 are tightly attached to the rolled steel plate to slide, the rolled steel plate can be effectively ground flat, the uncoiled rolled steel plate is further leveled, then under the arrangement of the first spring 19 and the second spring 28, the first clamping block 25, the first moving block 21 and the second sliding plate 32 are pushed to move back to the original state, the clamping force of the first clamping block 25 and the first moving block 21 on the rolled steel plate is gradually loosened, and the first cam 13 and the second cam 36 are rotated all the time, so that the rolled steel plate is effectively leveled while being conveyed, and the working efficiency is higher.
