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.

What is claimed is: 1. A switching mechanism for stapling modes of a stapler that comprises: a stapler main body, a trigger, a supporting member, a slide member, a spring, a hooking member and a torsion spring; wherein:the trigger has two sidewalls, a 1st pin and a 2nd pin provided at a bottom end of the trigger, and two symmetrical pivot holes and two symmetrical stopper recesses positioned on upper locations of its two sidewalls respectively;wherein the supporting member has pivot holes at a bottom end thereof, and a 1st protrusion at a top end thereof, wherein the pivot holes are adapted for connecting to the two symmetrical pivot holes of the trigger respectively;wherein the slide member has a sliding recess in one side for allowing the supporting member to slide against the recess, a 2nd protrusion on top, and a hook hole at a bottom end thereof;wherein the spring is connected-between the said 1st and 2nd protrusions; wherein the hooking member is connected to the said trigger by the said 2nd pin, and has a curved piece and a hook tip; wherein the torsion spring is fitted on the said hooking member.
