Abstract
A nice lever amplification force generating technology with changing the lever ratio are presented. It is discussed in detail that how to the precision force could be loaded up and down with controlling accurate position of the jockey-weight on the lever. And some problems are studied, for example, errors and its controlling, frame and work efficiency of the machine, economy cost, etc. Hereby the theoretical part of the lever amplification force generating technology with changing the lever ratio is established.
