Subject: A mechanism process description of a stapler Figure 1 Stapler Introduction A stapler is a portable "device that binds together sheets of paper by driving a thin metal staple through the sheets and folding over the ends to secure the paper".( Wikipedia) Most office staplers are 30 cm long, 9 cm wide, and 18 cm tall. The stapler is made of rubber, plastic, and metal. The main components of an office stapler include the base, the anvil, the magazine, the metal head, the case, the hanger, and the springs. Base The base is a 30 cm long, flat, box-shaped plastic container with anti-skid rubber pads attached at the bottom to ensure stability. Thus, by providing this stability, the base of the stapler also ensures precision, as slippage caused by the force required is prevented, and the staple is placed in the document where intended.
A staple is "a type of two-pronged, usually metal, device for joining or binding materials together". (Wikipedia) The amount of staples that can fit in the magazine depends on the size of the stapler. An average office magazine holds two hundred standard size (6.35 mm) staples. Metal Head Figure 3 Metal Head The metal head is a metal rectangular box which covers the magazine. Its main purpose is "to separate one single staple from the row of staples each time the metal head is forced down". (Ewers, William) This part of the device is slightly tilted from the base to ensure that documents can be slipped between the base and metal head and stapled. Case The case is a plastic cover with a length of 30 cm, width of 9 cm and height of 5 cm that covers the magazine and the springs.
One is a coil spring that connects the plastic case, which covers the metal head, to the magazine. The other is a leaf spring, which is made of rolled thin pieces of steel. The leaf spring in a stapler typically performs two separate jobs: it keeps the row of staples lined up in the magazine and "ready to be used, and it returns the metal head to its original upright position." (Ewers, William) Conclusion There many different types of staplers that are used in medicine, production and households, but the basic principles behind its mechanism remain the same for all of them. The bottom portion of the stapler, which includes the base, the anvil, and the hanger, and the top portion, comprised of the magazine, the case, the springs, and the metal head, form the perfect invention to secure documents together with staples.
