Gear-Toggle M anual PressW U lingyun，WEI Ruiyuan，WANG Guo(School of Mechanical and Electronic Engineering，Soochow University，Suzhou，Jiangsu 215021，China)Abstract：A symmetric gear-toggle manual press which could amplify force twice was designed.It is designed by use ofgear transmission and toggle mechanism combined in series.This paper introduced the working principle of the press，and gave the computational formula of its magnification.The press S structure is simple，and operation is convenient，etc..The press S characteristic are its hand shank can rotate 360 degree，and as the press cake move down the outputincreases，and also actual examples are used to illustrate the form ula。

手动压力机相对于其他驱动方式的压力机，结构简单，使用、维修方便，而且绿色环保，在制造业中占有- 席之地。其大多是依靠简单的杠杆机构或偏心凸轮机构，将人作用于手柄的力进行放大。但是，采用凸轮机构的压力机，其复位-般需要添加复位弹簧，或做成如
