As preferably, the operating side of shell fragment is also coated with flexible material.

Adopt after such scheme, the present invention is for fire extinguisher, under untapped original state, the neck of operating side is arranged in narrower perforation and draw-in groove coordinates with narrower perforation peritreme, locking bit on pressure handle now, valve pressure handle is in security protection state, and fire extinguisher cannot use.During use, the operating side that only need to touch forward shell fragment, draw-in groove departs from after narrower perforation, and the support that pressure handle loses draw-in groove can be pressed and move downward, and now fire extinguisher can normally use.After finishing using, stir pressure handle, shell fragment blocks pressure handle again, and valve pressure handle is in security protection state, thereby makes fire extinguisher in stand-by state.

The present invention replaces safety cock because increased strip shell fragment between carrying handle and pressure handle, by the draw-in groove of shell fragment neck, coordinates with the notch cuttype perforation on pressure handle, and realize the release of pressure handle and lock, so the present invention at least has following beneficial effect:

One, the operating side of shell fragment neck is positioned at the end face of pressure handle, is easily noted by the user, and when breaking out of fire, can remove to stir shell fragment to subconsciousness, makes to spray fire extinguisher;

Two, stir shell fragment ratio and take out that to dial safety cock action simpler, laborsaving, easily operation, when fire occurs, under even people's spirit is in tension, muscle is in automatic tightening, still may easily complete release action, conveniently after fire occurs, in the very first time, make to spray fire extinguisher, fire extinguishing opportunity avoids delay;

Three, after use, only need stir pressure handle the neck operating side of shell fragment is come back in narrower perforation, draw-in groove rebounds automatically, and shell fragment blocks pressure handle again, and valve pressure handle, in security protection state, facilitates the recycling of fire extinguisher.
