## Abstract

A staple gun has a main body, an adjusting strip and a positioning device. The main body has a cartridge having a staple recess, a through hole and a taking opening. The through hole and the taking opening are formed through a first inner side surface of the staple recess. The taking opening is next to and communicates with a recess opening of the staple recess. The adjusting strip is slidably mounted in the staple recess and has a positioning recess aligning with the through hole when the adjusting strip is securely positioned in the staple recess. The positioning device has a protrusion mounted through the through hole and mounted in and engaging the positioning recess. With the cartridge having the taking opening, the adjusting strip is easily taken out from the staple recess.
