Claims

[Scope of utility model registration request]

Consisting of double inner and outer cylinders 1 and 2, an inner piston 3 is provided with a hammer 4 having a hollow portion so that its tip can protrude outward from the outer cylinder 2, and a hollow space is provided on the side from which the hammer protrudes from the piston 3 of the inner cylinder 1. and a cavity housing the inner cylinder 1 of the outer cylinder 2 are in communication with each other, and a hanging shaft 6 protruding from the outer piston 5 penetrates the inner cylinder 1 and enters the hollow part of the hammer 4, and the hanging shaft Tsuba 7 at the tip of 6
In the acceleration device, the suspension shaft 6 is provided with a passage through which compressed air in the outer cylinder 2 flows into the inner cylinder 1 when the outer piston 5 approaches the inner cylinder 1, and the suspension shaft 6 has a circular cross section. An acceleration device using compressed air, in which the passage of the hanging shaft 6 is formed by disposing a plurality of vertically elongated grooves 10 at equal intervals in the circumferential direction.
