Claims

[Claims for Utility Model Registration] (1) A truncated shape having an inner cylinder with an open front end and a grip cylinder fitted on the outside of the inner cylinder and extending further rearward than the bottom plate of the inner cylinder. A conical outer cylinder, a lid that closes the front end opening of the inner cylinder and is detached by explosive force, an explosive body stored in the inner cylinder and exploded by pulling a drawstring, and this explosive body. ejected material stored in the inner cylinder so as to be ejected forward from the front end opening of the inner cylinder from which the lid is detached due to the explosive force of the lid, a storage area for this ejected material, and a storage area for the explosive body. In the cracker, the pull cord of the explosive body is inserted through the bottom plate of the inner cylinder and led out into the grip cylinder part of the outer cylinder. There is a dogleg-shaped bendable explosive operating body inside the grip tube.
One end comes into contact with the bottom plate of the inner cylinder and becomes a reaction force point, the other end becomes a movable point that can slide along the inner surface of the outer cylinder, and the bent part is formed on the peripheral wall of the outer cylinder. A gunpowder body is housed in a hole so as to serve as a pressing operation point, and a free end of a drawstring of the explosive body is locked and fixed to the movable point of the explosion operation body. (2) In claim 1, a plurality of the dogleg-shaped bendable explosive operating bodies are arranged in the circumferential direction, and the plurality of bendable explosive operating bodies are arranged as a result of crushing deformation of the entire grip cylinder portion of the outer cylinder. The gunpowder body's drawstring is pulled by the resultant force of the stretching forces of the gunpowder body.
