ABSTRACT:
The purpose of this invention is to provide 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, the slide member is pushed to open the air valve, and if the trigger is further pressed at this particular moment, the stapling counterforce will make the slide member escape the pressure from the safety device so as to finish a single stapling process. When the trigger is pressed first and then the safety device is pushed, the slide member is pushed to open the air valve, which makes the stapling process to continuous until the trigger is released. In other words, the above process makes a continuous stapling process.
