PROBLEM TO BE SOLVED: To increase the degree of freedom in a working posture in a glue gun using an aerosol type glue cartridge. SOLUTION: A socket 17 for setting the glue cartridge is fitted to the valve housing part 13 of the glue gun through a universal joint 16 which can move forward/backward and rotate. Springs and balls 20 are embedded in both sides of the joint 16, holes 21 are arranged at constant angular intervals in the shape of an arc on the inside surface of a guide bracket 19, the balls 20 are engaged with the holes 21 to form a click stop mechanism. The joint 16 is rotated manually, and the relative angle between a gun nozzle 15 and the glue cartridge is adjusted so that the glue can be applied also on the upper part of a wall surface, etc. |
