Since both the driven pulleys 72 are engaged with the driving pulley 71, the driven pulleys 72 are rotated in synchronization at this time. Since the right push rod 75 is initially distributed obliquely upward and the left push rod 75 is initially distributed obliquely downward, the right driven wheel 72 will drive the right push rod 75 and the right movable contact 76 to move downward when rotating, and the left driven wheel 72 will drive the left push rod 75 and the left movable contact 76 to move upward when rotating.

Since the first right fixed contact 79 is located at the highest point inside the right positioning frame 77, the second right fixed contact 710 is located at the lowest point inside the right positioning frame 77; the first left fixed contact 79 is located at the lowest point inside the left positioning frame 77, the second left fixed contact 710 is located at the highest point inside the left positioning frame 77, the first fixed contact 79 is electrically connected with the forward rotation circuit of the external motor, and the second fixed contact 710 is electrically connected with the reverse rotation circuit of the external motor, so that the two push rods 75 respectively drive the two movable contacts 76 to move towards the direction close to the second fixed contact 710 and finally contact with the second fixed contact 710.

At this time, the two wheels 74 are driven by the two push rods 75 to rotate clockwise synchronously, and finally rotate until one end of the wheels contacts with the driving wheel 71, so that the wheels are limited, meanwhile, the two movable contacts 76 contact with the two fixed contacts two 710, and the external motor starts to rotate reversely. When the movable contact 76 is rotated into contact with the two fixed contacts one 79, a cycle is completed, in the same principle as the above process, in the opposite direction.
