阅读说明：本技术 输入输出装置 (Input/output device ) 是由 王洪南 于 2020-05-17 设计创作，主要内容包括：一种输入输出装置,属于能把之前的动力扩大的一种机械。它是利用一个圆的周长大于这个圆直径1.5倍的原理,用这个圆周长做一个链带套在两个小链轮上把圆周运转改为横向(上下或左右)运转。在通过多次组合(输入、输出)能把第一次的动力扩大很多倍。优点：可以把之前的动力扩大,又不会对环境造成污染。(An input and output device belongs to a machine capable of expanding previous power. The principle that the circumference of a circle is 1.5 times larger than the diameter of the circle is utilized, and the circumference is used as a chain belt to be sleeved on two small chain wheels, so that the circumferential operation is changed into the transverse (up-down or left-right) operation. The first power can be expanded by multiple times through multiple combination (input and output). The advantages are that: the former power can be enlarged, and the environment can not be polluted.)
