The purpose of this invention is to propose a switching mechanism for switching stapling modes of a stapler, which mainly comprises a trigger, a supporting member, a slide member, a spring, a hooking member and a torsion spring. When the safety device of the stapler is pushed, then it further pushes the slide member to open the air valve, then at the moment, if the trigger is further pressed, the stapling counterforce will make the slide member escape the pressure from the safety device so to finish single stapling process. When the trigger is pressed first and then the safety device is pushed to further push the slide member to open the air valve, it will make stapling contentiously until the trigger is released. Above process then makes a contentious stapling.
