A gas heated glue gun (11) comprising:

• a body portion (12), a handle portion (13), a gluing member (14) projecting from said body portion (12);
• a window (19) on one side of said body portion (12);
• a melt cartridge (21) provided within said body portion (12) proximate to said gluing member (14);
• a guiding conduit (22) being provided within said body portion (12) immediately adjacent to said melt cartridge (21) for receiving a glue stick (23);
• a trigger (32) pivotably mounted within said body portion (12);
• a drawing means (41) located for communication with said trigger (32);
• said drawing means (41) being generally a shaft (42) having a laterally extending end part (43) for engaging with said trigger (32), and an integrally perpendicularly formed pulling plate (46) at an end remote from said laterally extending end part (43);
• said pulling plate (46) being a flat plate having a hole (49) thereon;
• a sparking means (51) located for communication with said trigger (32);
• said sparking means (51) including a stop plate (52) in contact with said trigger (32), a crystal (55) encircled by a coil (53), and two distinct wires extending from said coil (53);
• a first said extending wire (57) extending to a location proximate to an end of a gas control means;
• a second said extending wire (58) being electrically connected to said gas control means at another end;
• a gas supply means (61) being a gas chamber having an opening (62) at an upper side thereof;
• said gas supply means (61) further including a gas nozzle (63) and a gas valve (64) at a bottom side thereof for filling gas thereinto;
• said gas control means (71) including a first hose (72) having an end connected to said opening (62) of said gas chamber (61), and a second hose (73) receivable by said drawing means (41);
• said second hose (73) having an end part provided with a nozzle (74);
• said second hose (73) being receivable by said drawing means (41);
• said gas control means (71) further including an adjustable dial (76) covered with a ring (77) having a protruder (78);
• said protruder (78) being manually operable and projecting from said body portion (12) through said window (19);
• said second hose (73) being provided with an inlet (79) near an interconnection part with said first hose (72);
• a sleeve (80) partially covered with said adjustable dial (76) and ring (77) being rotatably mounted on said second hose (73) and covering said inlet (79);
• said sleeve (80) having a helical flange (81) on the inner wall thereof and being provided with a plug 82 and an aperture (82) on an outer face thereof;
• said helical flange (81) being slidable around said second hose (73) so as to cover said inlet (79) to different extents;
• said first hose (72) being partially mounted on said sleeve (80);
• said first hose (72) being internally provided with a plate (83) having an opening (84);
• said opening (84) being insertable by said plug (82);
• said plug (82) being detachable from said opening (84) to form a passage for gas;
• and
• a combustion chamber (91) including a plurality of vents (92), an end part of said combustion chamber (91) being provided with a bore (93) for receiving a cylindrical tube (94).
