What is the structure of the stapler

Stapler is also a kind of mechanical structure, part of the market stapler also clever use of labor-saving institutions, making the book to more convenient, easier to operate.

Ordinary stapler includes push (handle), pin, plate, shape-shifter, rivet, pressure device, base, spring, shrapnel, positioning shaft and other parts, connecting rod transmission structure plays the function of automatic spring back to push when the staple is installed, when the staple is closed on the handle and automatically make the push to work, resist the staple.

The press handle of the stapler, spring, shaft can constitute a force saving lever, the press handle is wide to reduce pressure, spring elastic potential energy into kinetic energy to make the stapler reset in time, the shaft is the pivot of the stapler, these three parts work together to increase the penetration of the stapler.

How the stapler works

The working principle of ordinary stapler is that the top, needle and clamp will rotate around the connecting pin when the end cover of the stapler is pressed forcefully by human hand. With the continuous application of human force, the top will rotate out of its natural state.

At this time, the top will do up and down movement around the connection pin slightly higher than the approximate height of a needle, end cover spring compression, shrapnel compression, will drive the needle downward movement;

After moving for a certain distance, the needle will touch the object requiring binding and pass through the object under the action of human power. After passing through the object, the needle will touch the mold, and the needle will bend, so as to realize the penetration binding between the needle and the object.

After binding, the force on the end cover of the needle is removed. At this time, the shrapnel will rebound, and the needle, clamp, top and end cover will rise under the action of elasticity.

The extension of the push spring allows the needle to be fed again, returning the stapler to its original state and waiting to be bound again.

Basic functions of stapler

According to the function importance of stapler, the function of stapler is divided into main function, secondary function and auxiliary function.

The main functions include needle mounting and stitching, the secondary functions include changing the shape of needle binding, and the auxiliary functions include anti-skid and anti-noise functions. Each function can be divided into some sub-functions according to its implementation steps.

The needle function can be divided into the cover opening function, the end cover opening function, the needle placing function, the fixed needle function and the cover closing function.Stitch function can also be subdivided into book function, semi-automatic needle function, binding function, automatic top function, automatic rebound function and ham book function;

The function of changing the shape of needle binding can be divided into the function of ejecting the needle mold, changing the shape of the needle mold, fixing the needle mold on return trip and locating the needle mold.Anti-skid and anti-noise function, trademark display function.
