当滑板继续向下滑动时,尾柱就会与沿槽斜面P发生作用,产生一个向左的分力,推动托盘开始出仓。当尾柱将要到达C点时,驱动齿轮开始与托盘齿条相啮合,至此托盘的出仓才是真正由驱动齿轮来驱动。当尾柱到达C点时,滑板因失去与中间齿轮的啮合而停止滑动,滑板尾柱也就停止向下运动了,只是在托盘滑槽D段里做横向滑动。托盘出仓到位,托盘凸台将 As the skateboard continues to slide downward, the stern post will interact with groove slope P to create a left force component, pushing the tray out of the bin. When the tailpost is about to reach point C, the drive gear begins to mesh with the rack and pinion, and the tray exit is really driven by the drive gear. When the tail post arrives at point C, the slide plate stops sliding due to the loss of engagement with the intermediate gear, and the stern post also stops moving downwards, only sliding laterally in section D of the tray chute. Tray in place, tray boss will be
