SUGGESTION FOR IMPROVEMENTS

 

  1. This type of stapler is little big in size and it can not be carried comfortably .So it can be modified into a papersheet type device which we can carry in our pocket or purse.


    2.  

  2. Staples are made of mild steel ,a fairly ductile material having low toughness which causes them to bend sometimes while being stapled into a band of paper. so the material used should be improved in terms of toughness value keeping its other properties same.


    3.  

  3. The area of the staple pin that experiences bending forces is very small which result in high stress value .this can be avoided by simply increasing the upper area of the pins.


    4.  

  4. The locking arrangement is done by simply punching two points in the raceway and thus raising material at two points which wears very soon and hence this locking device fails very soon which can be improved by avoiding this type of locking system.We can use two different leaf springs.One between raceway and bash,other one between body and a plate used to give proper support during stapling.

  5. We can use a guideway to support staples when they are in raceway.
  6. We can use compresion spring in place of extension spring for this we will have to give a support to avoid buckling.
