Abstract
A pneumatic caulking gun includes a gun body, an air valve, a control unit, a trigger, a barrel, a push plate, a connecting base, a safety valve, and a push rod. Thus, the trigger is pressed to fill the pressurized air with the barrel successively to push the push plate forward to compress and squeeze the silicone gel, thereby injecting the silicone gel outward from the nozzle of the barrel automatically. In addition, the user only needs to slightly press the trigger by his one hand to squeeze the silicone gel outward, thereby facilitating the user operating the caulking gun, and thereby saving the manual work.
