1) Primary Function
The primary function is to add staples into a paper or anything that you want some people use it to put things together that involves like cartboard.


2) How I Think It Works

A stapler works by using force to push a staple through the paper, then secure the pages together. It can be used for locking pages of a document together, or for tacking, when the stapler is opened up and used to staple items to a flat surface
the head and the base . Connected to the head is the magazine , which holds the staples. The head is connected to the base by a hangar , which is soldered in place. The pin at the back of the stapler allows the head to swing up and down to load staples or in some models open up completely for use.

the loading zone- The staples are loaded into the magazine so that the two points face towards the base of the stapler.
The spring -creates tension that pushes the staples toward the front of the stapler. When pressure is applied to the head of the stapler, the magazine pushes down on the paper, and a metal plate in the head of the stapler pushes the front staple down the magazine. The two points are forced into the paper, piercing the pages until they come into contact with the anvil.
There is a curved groove -in the anvil. The ends of the staple are forced into this groove, where the pressure forces them to bend. They bend inwards, creating a lock around the pages.

4) Visible Mechanical Components
the two mechanical component is when you push it down and the staple comes and also when you add the staples into the stapler it pushes them to the front for when you press it down it can come out..





5) A Function That Cannot Be Identified
i dont think its hard to identified everything about the stapler becuase its a easy mechanically. the springs makes everything happen for me becuase they give it the force.
