Detonator with spatial-cross-shaped center

The utility model aims to provide a detonator with a spatial-cross-shaped center. The detonator comprises an induction detonating device, a positioning and connecting guide tube, a longitudinal detonator, a transverse detonator and a connecting sleeve. The induction detonating device is connected with the longitudinal detonator by the positioning and connecting guide tube, and the longitudinal detonator is connected with the transverse detonator by the connecting sleeve. By the detonator with the spatial-cross-shaped center, superfine dry powder extinguishing agents can be dispersed to form ellipsoids and are dispersed in a fire scene in a mode that the flooding concentration of the superfine dry powder extinguishing agents is uniform, large quantities of extinguishing agents can be saved, and fire extinguishing efficiency of a forest firefighting bomb is improved.
