Rotary safety igniting gun

The utility model relates to a rotary safety igniting gun, which is composed of a gun body, a gun tube, a switch, a piezoelectric device, a seesaw, a steam box body, etc. The upper and the lower shoulder-blades which are in the shape of a half round arc of a left and a right gun housing and convex edges on the left and the right cylinder surfaces of the switch are used, which enables the switch to move up and down in a cylinder composed of the upper and the lower shoulder-blades and to have spacing rotation. At the same time, the convex edges of the switch can enter the upper and the lower shoulder-blades and is limited to move up and down, and thus double purposes of press ignition and safety can be achieved. The separated structure of a press-open switch and the safety switch of a traditional igniting gun is changed by the utility model, and the press-open switch and the safety switch are combined into integration. The press and the safety switch are replaced by a rotary switch. Thus the utility model has the advantages of structure simplifying, convenient operation and further safety improvement.
