Abstract
In the apparatus, under the action of the explosion of a mixture of air and gas in a chamber closed by a chamber sleeve tube and a cage when the apparatus is pressed against something, a piston is propelled in a cylinder to drive an element. The chamber sleeve tube and the cylinder are arranged in such a way that, as the apparatus is closed, the chamber sleeve tube comes into abutment against the cylinder. The invention can well be applied to nail guns and other staplers.
