[0023] Working principle: in use, the utility model is opened through synchronous control of the speed reducer 11, when the speed reducer 11 is opened through synchronous control, the speed reducer 11 drives the third transmission gear 12 to rotate, when the third transmission gear 12 rotates, it drives the first transmission gear 9 to rotate through a chain transmission, when the first transmission gear 9 rotates, it drives the adjusting screw 6 to rotate, at the same time, when the first transmission gear 9 rotates, it drives the second transmission gear 10 to rotate, when the second transmission gear 10 rotates, it synchronously drives all the second transmission gears 10 and the adjusting screw 6 to rotate through a chain, when the adjusting screw 6 rotates synchronously, it drives the moving adjusting seat 8 to move inwards along the outer curved surface of the limiting sliding rod 7 synchronously due to the action force of the outer curved surface screw connection between the adjusting screw 6 and the moving adjusting seat 8, when the moving adjusting seat 8 moves inwards synchronously, it pushes the rolling mill body 1 to move in the center along the inner side of the limiting sliding rail 4 synchronously, so that when the speed reducer 11 is opened through synchronous control, the moving adjusting seat 8 pushes the rolling mill body 1 to move in the center synchronously.

[0024] Meanwhile, when the reduction motor 11 supporting the one side outer wall of the support base 2 is controlled to start, the reduction motor 11 will drive the moving adjusting seat 8 of the one side of the rolling mill body 1 to move synchronously in and out, when the moving adjusting seat 8 of the one side of the rolling mill body 1 moves synchronously in and out, it can push the rolling mill body 1 to move linearly in and out, so as to realize the function that when the rolling mill body 1 moves linearly in and out, it can push the rolling mill body 1 to move linearly in and out, avoid the situation that only one rolling mill body 1 can be adjusted, which leads to slow adjustment precision and efficiency.
