ABSTRACT:
An effort-saving stapler includes a shell device and a triggering device installed to the shell device. The triggering device includes a trigger, an operation element and two bearings. An end of the trigger defines a lever for user to hold, and another end of the trigger includes teeth engaging with the shell device. A pivot pin is adapted for inserting through the trigger, the operation element and the bearings so that the pivot pin can drive the operation element to move in the trigger. A limit pin is adapted for inserting through the trigger and the operation element and abuts with the shell device. The pivot pin is regarded as a fulcrum, while the trigger is pressed, the teeth of trigger engage with the shell device so that the pivot pin quickly moves with the trigger.
