How to replace spring - Black & Decker 5700 Powershot Forward Action Stapler

Hope the following is clear if not write back and I'll try to clarify, if you look at the body of the stabler molded to the body there is a bump that is round on the botton and kinda notched on top. the round part of the spring fits around the bump. The spring has a straight side and bent side. the straight side rests against the a flat bump which is slight back and lower than the round bump. the bent side clips into the notch on the handle (clip this end in last) I used a plier but there is very little tension involved the spring just returns the handle to the at rest position,

Rexel Odyssey heavy duty stapler: The pring that pushes the staples into position can come losse if the stapler iss dropped. It's difficult to work out how to replace it! However, there are only two "lugs" that will take the circular ends of the spring. One obviously fits to the sliding staple retainer. The other to the back end of the pressed-metal inner body. However, to work, the spring must be threaded from this point along the pressed metal parallel-sided inner body over a rounded bent piece (shiny from prvious friction) and back down to the sliding staple retainer. It's trickey to do, but that's where it has to go in order to provide forward tension when the Stapler is closed.
