You are a negative person. Everything has its proper use. It may require some development and correction, but This device can transmit power to three different devices with one motor. and it also can be transformed to perform three different movements. This is an item that can be used as a core power transmission device when complex operations must be performed in a very narrow space. Of course, a similar type of power transmission method has already been designed in the past, but engineers who have taken this complex approach are the ones creating the end content.
