ABSTRACT:
A setting tool for nails comprises a hollow cylindrical grip sleeve open at both ends with a first hollow section connected by a through-opening to a second hollow section, a ram being disposed in the first hollow section and having one end with an arrangement for releasably holding a nail extending from a first end of the grip sleeve, a pin being disposed in the first hollow section between the ram and the through-opening, the pin having a first segment connected by a centering section to a second segment which extends through the through-opening, a coupling member having a blind bore of the diameter of the second segment being disposed in the second hollow section, with the blind bore facing the pin and being urged toward the pin by a compression spring disposed in the second hollow section entrapped between the coupling member and an adjustable device. Thus, when the ram is engaged on a surface and pushed into the hollow sleeve, the pin pushes the coupling member against the compression spring until the centering section enters the through-opening to cause the axis of the pin to become aligned with the axis of the blind bore to enter the blind bore to release the coupling member to impact the pin and ram to set the nail.
