台虎钳在机械加工企业、水暖安装、修理等行业应用十分广泛 ,传统台虎钳的构造见图 1。图 1　传统台虎钳构造简图操作时 ,转动手柄使丝杠旋转 ,由于丝杠螺母是与固定夹脚固定在一起的 ,而丝杠与活动夹脚在丝杠轴向是相对固定的 ,因此 ,当丝杠由手柄旋转 1周 ,活动夹脚相对固定 Taiwan vice in mechanical processing enterprises, plumbing installation, repair and other industries are widely used, the traditional bench vice construction shown in Figure 1. In the operation of the traditional vise construction, turning the handle rotates the screw, since the screw nut is fixed together with the fixed clamping pin, the screw and the movable clamping pin are relatively fixed in the axial direction of the screw, Therefore, when the screw is rotated by the handle for 1 week, the movable clamp is relatively fixed
