1. A caulking gun for dispensing material comprising
a stock (1),
a cartridge keep (2),
a push rod (3) longitudinally moveably mounted in the stock (1) provided at one end of the rod with a plunger (4) which engages a piston of a cartridge placed in the cartridge keep (2),
a catch member placed on the push rod (3),
a trigger (6) coupled to the catch member via an axle (15) and pivoting about a pivot point (7),
means for varying a thrust output exerted on the push rod (3) when pressing the trigger (6) for a given strength exerted on the trigger (6), wherein the means for modifying the thrust output allow the displacement of the axle (15) between at least a first position and a second position,
wherein the trigger (6) has an upper part with a trigger bridge (11) in which two long holes (9) are provided and the means for varying the thrust output comprise a ratio bridge element (8) which is put over the trigger bridge (11) and trigger (6) and which is linked to the trigger (6) via the axle (15) which traverses the two long holes (9) and that engages the catch member.
