But Hutchings argues that the sketch actually shows blocks on the ground being pulled by a weight attached to a pulley—the same type of experiment you might do today in a high school physics class.
但是哈钦斯却认为，在这张草图中，放置在地上的数个方块由配有滑轮装置砝码拖动——这和高中物理课上做的实验类型简直如出一辙。
The rocker arm is connected with the balance weight block through a rotary shaft, a cam, a pulley, a steel cable and a lifting rod, and an initial position can be selected through a barrier shaft.
摇臂通过转轴、凸轮、滑轮、钢丝绳、提升杆与配重块相连，初始位置可由挡轴选定；
