A glue gun comprising:
- a housing having a switch opening, two longitudinal sliding tracks bilaterally disposed on the inside, and a chuck holder spaced behind said sliding tracks;
- an igniter and gas burner unit mounted inside said housing and holding a disposable cigarette lighter and controlled to produce a flame at a flame nozzle thereof;
- a metal barrel mounted in said housing and moved along said sliding tracks, said metal barrel comprising a heating chamber which receives the flame nozzle of said igniter and gas burner unit, a fusion chamber above said heating chamber, and two wings raised from two opposite sides of said fusion chamber and supported on said sliding tracks;
- an one-way chuck mounted in said chuck holder inside said housing behind said barrel, said one-way chuck having a plurality of clamping strips;
- an one-way clamp mounted inside said housing in front of said chuck, said one-way clamp comprising a plurality of clamping strips;
- a silicon rubber seal ring mounted in an entrance at said fusion chamber of said barrel;
- an one-way annular binder mounted in the entrance at said fusion chamber behind said silicon rubber seal ring, said one-way annular binder comprising a plurality of clamping strips on the inside;
- a spring mounted around said barrel and stopped between the wings of said barrel and said chuck holder, said spring imparting a forward pressure to said barrel;
- a glue stick inserted through said one-way chuck, said one-way clamp and said one-way annular binder into said fusion chamber, and retained in place by the clamping strips of said one-way chuck and the clamping strips of said one-way clamp and the clamping strips of said one-way annular binder, said glue stick being allowed to be moved forwards through said one-way chuck, said one-way clamp and said one-way annular binder into said fusion chamber, and prohibited from backward movement by the clamping strips of said one-way chuck, said one-way clamp and said one-way annular binder.
