    • A hand-operated staple-driving tool having a multi-stage operating movement of the operating handle resulting in a first cocked position of the staple-driving mechanism achieved through the employment of a latch pin operable after a predetermined length of travel of the staple-driving mechanism by compression movement on the handle, and a positive releasing of the latch pin upon successive movement of the handle after operating the staple-driving mechanism; such construction and function requiring less compression force for each handle movement and thus resulting in easier yet effective operation of the tool.
    • 一种具有操作手柄的多级操作运动的手动订书钉驱动工具,其通过使用可在订书钉驱动机构的预定长度行进之后操作的闩锁销​​实现订书钉驱动机构的第一定位位置, 驱动机构通过手柄上的压缩运动,以及在操作订书钉驱动机构之后在手柄的连续移动时释放闩锁销; 这种结构和功能对于每个手柄运动需要较小的压缩力,因此导致工具的更容易而有效的操作。
