The transmission device is composed of rotary motion mechanism and vertical motion mechanism. The rotary motion mechanism is composed of synchronous belt transmission planetary gear train composed of synchronous belt transmission and upper and lower connecting arms to ensure that the product rotates 90° counterclockwise and 90°clockwise; The vertical motion mechanism is composed of cylinder, ball and spline transmission technology. The transmission device is flexibly implanted into the curriculum with the carrier of new technology and new process, which feeds back the teaching, and takes the curriculum thought and politics as the guide to implement the teaching.
