A silicone gun comprises a silicone canister holder (40) to hold a silicone canister (50) and a butt (10) fastened to the rear end of the silicone canister holder (50) and extended to form a handle (112). The butt (10) is hinged with a guide wheel (15) on a rear upper end and holds a silicone compression means (20) which includes a thrust member (24) and a retaining member (26) run through by a flexible push member (21) in the butt (10). The push member (21) has a front end extended to the silicone canister holder (40) and fastened to a thrust disc (211). The handle (112) is hinged with a trigger (30) which is depressible to release and drive the push member (21) to compress and squeeze out silicone. The push member (21) runs through the retaining member (26) and winds on the guide wheel (15) and passes through the upper side of the silicone canister holder (40), and can be loosened for release and retraction, thus is not extended outside the butt (10) at an excessive length to avoid causing use inconvenience at work sites. Carrying and storing also is easier, and usability improves. |
