Basic Information Of Stapler

A stapler is an appliance that is mainly used to bind a certain number of paper-like articles together through the deformation of the staples in the stapler.

The stapler uses the principle of leverage.

Large stapler is more obvious, the position of the nail is about half of the length of the shaft from the handle, and the force arm for human action is longer, so it saves effort. Ordinary small staplers basically do not save effort, and the moment arm is the same.
