Explosive discharge actuated tool for driving fasteners

An explosive discharge actuated tool used with a multi-cartridge strip for driving fasteners, the multi-cartridge strip including a strip body and multiple cartridges loaded on the strip body, the strip body having multiple side notches respectively corresponding to the cartridges, said explosive discharge actuated tool comprising:

• a tool housing having a strip accommodation channel which extends in an upright direction for accommodating the strip, said strip accommodation channel having a firing position where a cartridge to be detonated is loaded;
• a firing module disposed within said tool housing and located rearwardly of said firing position;
• and
• a trigger and cartridge advancing module including
• a mounting frame disposed securely within said tool housing,
• a trigger lever pivotably attached to said mounting frame,
• a cartridge advancing lever pivotably attached to said mounting frame and having a strip-engage end which is turnable to be fitted to one of the side notches that corresponds to the cartridge in said firing position,
• a link bar pivotably connected between said trigger lever and said cartridge advancing lever such that turning of said trigger lever causes turning of said cartridge advancing lever,
• a trigger disposed to be pulled to turn said trigger lever to drive said firing module into the cartridge in said firing position and, through said link bar, to turn said cartridge advancing lever so as to move said strip-engage end to engage with a next one of the side notches that corresponds to the next cartridge, and
• a biasing returning member disposed to bias said cartridge advancing lever, said link bar, said trigger lever and said trigger to return to their original positions, and to result in, during returning of said cartridge advancing lever, an upward and advancing movement of said strip-engage end and the strip so as to move the next cartridge to said firing position;
• said mounting frame having a guideway which penetrates in a front-and-rear direction that is transverse to the upright direction and which is elongated in the upright direction, said trigger lever having a guided portion which is fittingly extended through said guideway to stabilize the turning of said trigger lever.
