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.

Abstract: A switch mechanism for a stapler includes a trigger, a pivotable member, and a swing member, which is pivotably connected to the trigger by two pins. The pivotable member has a first protrusion extending from a top of the pivotable member. The pivotable member is received in a recess of the slide member and a second protrusion extends from an inner top end thereof A spring is connected between the first and second protrusions so that the slide member is movable relative to the pivotable member. The swing member includes a first curved part and a second curved part which is located at a side of the pivotable member. The curved part of the swing member is inserted into a hole of the slide member when pulling the trigger, and the slide member is moved downward to change the relative position between the slide member and the valve of the stapler.

Abstract: 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.
