[0012] In this solution, a person can rotate the handle, the PLC controls the rotation of the motor, and the driving wheel one is driven through the sprockets and chains. Then, through the movement of the sprockets and chains between the two driving wheels, synchronous movement is achieved.
[0013] Meanwhile, the encoder structural component records the rotation angle on the driving wheel and feeds it back to the PLC in real time to ensure the correctness of the rotation angle. If there is a deviation from the angle corresponding to the handle, automatic adjustment can be achieved.

Meanwhile, during the previous transmission process, the first driven sprocket group, the second driven sprocket group, the third driven sprocket group, the fourth driven sprocket group, and the first driving wheel sprocket will also be driven accordingly, and the first driving wheel group will also rotate by a corresponding angle. Finally, under the corresponding transmission movement, the second driving wheel group and the first driving wheel group will rotate together to achieve synchronous movement. Meanwhile, under the transmission of the third driven sprocket group and the encoder sprocket, the encoder group will record the rotation angle on the second driving wheel group and feed it back to the PLC in real time to ensure the correctness of the rotation angle. If there is a deviation from the angle corresponding to the handle, automatic adjustment can be achieved.
