摘要： An electrically powered stapler is disclosed having a sliding blade for driving staples which is reciprocated by a lever and crank mechanism driven by an electric motor through a torque increasing gear train. Jamming of the stapler is prevented by mounting the lever's fulcrum on a plunger which is releasably retained to a fixed support by a flexible collar. The plunger has an enlarged head, and the collar has a plurality of flexible fingers which grip the plunger behind the head to retain the plunger to the collar. The plunger can be disengaged from the collar by the application of a predetermined force directed away from the plunger, such as occurs on the fulcrum during a jammed condition when the blade cannot drive a staple and is stalled. The pivot point of the lever then shifts to the blade end of the lever and the plunger is reciprocated by the lever instead of the blade, allowing the motor and other components to cycle through their full range of motion without stalling. The plunger is reengaged into the collar automatically as the plunger is reciprocated and the stapler is again ready to staple.
摘要翻译：公开了一种电动订书机，其具有用于驱动订书钉的滑动叶片，所述滑动叶片由杠杆和由电动机驱动的曲柄机构通过扭矩增加齿轮系往复运动。通过将杠杆的支点安装在通过柔性套环可释放地保持到固定支撑件的柱塞上来防止订书机的卡住。柱塞具有扩大的头部，并且套环具有多个柔性指状物，其将柱塞夹在头部后面以将柱塞保持在套环上。柱塞可以通过施加远离柱塞的预定力而与套环分离，例如当卡盘不能驱动订书钉并停滞时在卡住状态下发生在支点上。然后，杠杆的枢转点移动到杠杆的刀片端部，并且柱塞通过杠杆而不是刀片往复运动，允许电动机和其它部件循环通过其全部运动范围而不停滞。当柱塞往复运动时，柱塞自动重新接合到轴环中，并且订书机再次准备好订书钉。
