A firing device is provided with a housing, a sleeve in the housing, an air canister in the sleeve, a mechanism, and a pushing assembly. Pushing of the sliding cap forward exposes the push button and moves the spring depressible detent to the first depression, a pressing of the push button pushes down the sliding member, the pressing does not push down the sliding member further after the sliding member clearing the second though hole, the sharp member is pushed rearward by the spring biased cylindrical member to open the air canister by piercing, pressurized air released from the air canister pushes the mechanism including the sliding member back to a position prior to the pressing, the pressurized air travels forward to be stopped by the diaphragm with air pressure being further increased, and the diaphragm will be broken after the air pressure increase exceeds a predetermined pressure.

1. A firing device comprising: a cylindrical housing comprising a rear case, a forward hollow member, an elongated slot formed on a circumferential surface and including a first through hole, a stop member releasably fastened on the slot rearward of the first through hole, first and second depressions formed on the slot forwardly of the first through hole, a raised sliding cap slidably disposed on the slot to contact the stop member with both the through hole and the second depression being concealed, and a spring depressible detent disposed in the sliding cap and positioned in the second depression;a sleeve disposed in the housing and comprising a forward diaphragm and a second through hole formed on a circumferential surface and being aligned with the first through hole;an air canister disposed in the sleeve;a mechanism comprising a spring biased cylindrical member anchored in the sleeve, a receptacle formed in the cylindrical member, a spring biased sliding member disposed in and projecting out of the receptacle into the second through hole, and a sharp member disposed at a rear end of the cylindrical member, the sharp member facing and spaced from a front end of the air canister; anda pushing assembly comprising a lower support including an internally threaded cup disposed through the first through hole, a projection extending downward from an underside of the internally threaded cup to urge against the sliding member, and an annular first flange formed on a joining portion of the internally threaded cup and the first projection; a top push button concealed by the sliding cap and including an annular second flange and an externally threaded shank projecting downward to secure to the internally threaded cup; and a spring member anchored between the first flange and the second flange;wherein a pushing of the sliding cap forward exposes the push button and moves the spring depressible detent to the first depression to be positioned, a pressing of the push button pushes down both the projection and the sliding member with the spring member being compressed, the pressing does not push down the sliding member further after the sliding member clearing the second though hole, the sharp member is pushed rearward by the spring biased cylindrical member to open the air canister by piercing, pressurized air released from the air canister pushes the mechanism including the spring biased sliding member back to a position prior to the pressing, the pressurized air travels forward to be stopped by the diaphragm with air pressure being further increased, the diaphragm will be broken after the air pressure increase exceeds a predetermined pressure, and the pressurized air further travels forward to pass through the forward hollow member.
