This caulking gun contains the silicone sealant. The Front parts consist of the Sealant support frame (11) which included the Support plate (12) with Nozzle holder (12a). The Rear parts consist of Body (10) with Gun handle (13), Push-rod (20) which connected Sealant support frame (11) through the rear of Body (20) and Operation section (14), Pressure plate (21), Onward part (30) and Release part (40). The Onward part (30) in the Operation section (14) contains Onward plate restoration spring (31), Onward plate (32) and Trigger (33). The Release parts (40) contain Lock/unlock plate (42), Bracket (41) and Stop restoration spring (43). The above functions and ameliorations bring more convenience of usages and upgraded duration and operation. The Stop restoration spring (43) supports Onward plate (32) so that Trigger (33) moves smoothly and less power. Withdraw of push-rod operates automatically and immediately, length of Elongation spring (50) is same as space between the pressure plate in the sealant and edge of body therefore operate right away without any pretreatment unlike common caulking gun. Due to structure of Support plate (12) and Sealant holder (15), the pressure of sealant decentralizes so that it prevents from any damage and break also support ease replacement of the sealant.
