In the event that paper sheets are put into the stapling machine, a trigger will set the solenoid on which in turn will pull the hammer (soft iron core) due to induced magnetism. As the hammer moves down it will strike the staplers on the steel stapler slide and force then down and through the papers where they will be bent by the lower surface to hold the papers together. The hammer is then pulled back by the return spring to await the nextiu trigger.
Advantages of the design
1. The device is not bulky with this design and is light in weight.
2. By placing a simple switch to control the amount of current reaching the solenoid, one can staple papers ranging from few to bulks without having to buy a heavy duty model of the same.
3. The device has no gears hence doesn't need any
