1·The manual pressing section makes the downward movement by a slide cylinder and a pressing head driven by a pressing rod, and the travel of the pressing head is controlled by a limited ring;

手动按压部分由按压杆带动滑柱及按压头向下运动，并通过限位环来控制按压头的行程；

2·The friction force in the clutch works just like the blocks in the frication section of brake, except that the spring presses on the clutch plate instead of weight pressing the block into the ground.

离合器的摩擦力和制动器的摩擦力起一样的作用，不同的是压在地面上的重压力变成了离合器中弹簧压在离合器盘上的压力。

3·Moreover, a backward side with respect to the pressing direction has a circular section and its diameter is substantially same as the inner diameter of the container.

其加压方向后方侧的断面形状是圆形，其直径略等于成形用模体的内径。
