A trigger assembly for a staple gun includes a trigger with an activation member received therein and an adjusting member engaged with the trigger. A cam rod rotatable extends through the body of the staple gun, the passage at an end of the trigger and an eccentric hole in the adjusting member. The adjusting member has a lug which can be engaged with two of the positioning notches defined in the body of the staple gun. The activation plate and the trigger can be lowered or lifted by rotating the adjusting member, and this adjustment changes the relative positions between the activation member, the valve of the staple gun and the safety plate so as to have single shooting or auto shooting feature.
