摘要： A hydraulic, pneumatic, or electric tool may include a spindle that is adapted for rotational movement. A swing arm may be coupled to the spindle such that the rotational motion of the spindle is transferred to the swing arm. The swing arm may make contact with an anvil such that the rotational motion of the swing arm causes the anvil to move along a linear path. A piston may be operatively coupled to the anvil to follow the linear movement of the anvil. The piston may be adapted to interact with an energy storage medium when the swing arm moves the anvil in the first direction, causing energy to be stored. As the swing arm continues to rotate, the swing arm may lose contact with the anvil, thus allowing the energy storage medium to urge the piston and the anvil in a second direction opposite the first direction.
摘要翻译：液压，气动或电动工具可以包括适于旋转运动的主轴。摆臂可以联接到主轴，使得主轴的旋转运动被传递到摆臂。摆臂可以与砧座接触，使得摆臂的旋转运动使得砧座沿着线性路径移动。活塞可以可操作地联接到砧座以跟随砧座的线性运动。当摆臂沿第一方向移动砧座时，活塞可以适于与能量存储介质相互作用，导致能量被储存。当摆臂继续旋转时，摆臂可能会失去与砧的接触，从而允许储能介质沿与第一方向相反的第二方向推动活塞和砧座。
