Gas fixing tool

A fastener-driving tool comprising:

• a trigger movable between a rest position and a firing position, the trigger including:
• an upper end;
• and
• a surface engageable by a finger of a user, the surface positioned opposite the upper end;
• a fuel injection device actuatable to dispense fuel;
• an actuating member movable from a non-actuating position to an actuating position to actuate the fuel injection device;
• a bearing member operably connected to the actuating member to move the actuating member from the non-actuating position to the actuating position;
• and
• a safety member engageable with the upper end of the trigger, the safety member movable between a lock position and an unlock position, wherein when in the lock position the safety member prevents the trigger from moving from the rest position to the firing position,
• wherein the actuating member is operatively connectable to the safety member to move the safety member from the lock position to the unlock position, and
• wherein the actuating member is positioned to contact the safety member to move the safety member from the lock position to the unlock position when moving from the non-actuating position to the actuating position.

A fastener-driving tool comprising:

• a trigger movable between a rest position and a firing position;
• a fuel injection device actuatable to dispense fuel;
• an actuating member pivotable from a non-actuating position to an actuating position to actuate the fuel injection device;
• a bearing member operably connected to the actuating member to move the actuating member from the non-actuating position to the actuating position;
• and
• a safety member pivotably connected to the trigger and movable between a lock position and an unlock position,
• wherein when the actuating member is in the non-actuating position and the safety member is in the lock position, the safety member prevents the trigger from moving from the rest position to the firing position, and
• wherein the trigger is operatively connected to the safety member such that, when the actuating member is in the actuating position, movement of the trigger from the rest position to the firing position causes the safety member to move from the lock position to the unlock position.

A fastener-driving tool comprising:

• a housing;
• a combustion chamber at least partially within the housing;
• a trigger pivotable about a first axis relative to the housing between a rest position and a firing position;
• a fuel injection device in fluid communication with the combustion chamber and actuatable to dispense fuel into the combustion chamber;
• an actuating member pivotable relative to the housing from a non-actuating position to an actuating position to actuate the fuel injection device;
• a bearing member movable from a first position to a second position, the bearing member operably connected to the actuating member to move the actuating member from the non-actuating position to the actuating position when moving from the first position to the second position;
• and
• a safety member movable laterally along a second axis transverse to the first axis, the safety member positioned to prevent the trigger from pivoting from the rest position to the firing position when the actuating member is in the non-actuating position,
• wherein the safety member is movable relative to the housing between a lock position and an unlock position, and wherein when in the lock position the safety member prevents the trigger from moving from the rest position to the firing position,
• wherein the actuating member is operatively connectable to the safety member to move the safety member from the lock position to the unlock position when moving from the non-actuating position to the actuating position, and
• wherein the actuating member is positioned to contact the safety member to move the safety member from the lock position to the unlock position when moving from the non-actuating position to the actuating position.

• a combustion chamber at least partially within the housing;
• a trigger pivotable about a first axis relative to the housing between a rest position and a firing position;
• a fuel injection device in fluid communication with the combustion chamber and actuatable to dispense fuel into the combustion chamber;
• an actuating member pivotable relative to the housing from a non-actuating position to an actuating position to actuate the fuel injection device;
• a bearing member movable from a first position to a second position, the bearing member operably connected to the actuating member to move the actuating member from the non-actuating position to the actuating position when moving from the first position to the second position;
• and
• a safety member movable laterally along a second axis transverse to the first axis, the safety member positioned to prevent the trigger from pivoting from the rest position to the firing position when the actuating member is in the non-actuating position,
• wherein the safety member is movable relative to the housing between a lock position and an unlock position, and wherein when in the lock position the safety member prevents the trigger from moving from the rest position to the firing position, and
• wherein the trigger is operatively connected to the safety member to move the safety member from the lock position to the unlock position when moving from the rest position to the firing position.
