摘要： A push-up lever is rotatably supported on a sewing machine frame, and a coupling lever is coupled to the push-up lever. An oscillating shaft is rotatably supported on a bush, and the coupling lever is engaged with a part of the oscillating shaft. A presser base is coupled to a crank piece of the oscillating shaft, and a presser foot is fixed at its leading end. An elastic member engaged with the presser base. A bracket changeable in fixing position is supported on the back side of the sewing machine frame, and the bush is fixed in the bracket. The crank piece of the oscillating shaft is separable in two pieces, and the engaging faces of the two separated crank pieces are fixed anew when changing the fixing position of the bracket. Therefore, the circular track of the presser foot near the platform of the sewing machine bed can be changed easily, and an eccentric portion of the crank piece is not changed from an initial setting position.
摘要翻译：上推杆被可旋转地支撑在缝纫机框架上，并且联接杆联接到上推杆。摆动轴可旋转地支撑在衬套上，并且联接杆与摆动轴的一部分接合。压脚基座连接到摆动轴的曲柄片上，压脚固定在其前端。与压脚基部接合的弹性部件。在缝纫机框架的背面侧支撑固定位置更换的托架，将支座固定在支架上。摆动轴的曲柄片可分离成两片，并且在更换支架的固定位置时，两个分离的曲柄块的接合面重新固定。因此，可以容易地改变靠近缝纫机平台的压脚的圆形轨迹，并且曲柄片的偏心部分不会从初始设定位置变化。
