Abstract: A fastener driver including a housing, a driving mechanism located in the housing, an emission mechanism, a first guide member and second guide members is provided. The emission mechanism includes a piston, a driver firing pin attached to the piston, a bias mechanism and a jack assembly. The bias mechanism is provided with a first end portion supported in the piston and a second end portion supported by a head portion. The jack assembly is operated by the driving mechanism to enable the piston and the driver firing pin to move from the second position to the first position against a bias force of the bias mechanism. The first guide member movably supports the piston. The second guide members movably support a support frame. The second guide members are positioned between the first guide member and the jack, and disposed in parallel to the first guide member.

Abstract: A nailing unit includes a nail box, a nail magazine, a nail pushing block, a tail buckle switch, a nail limiting block fit together with a nail guiding plate through slits is provided. The nail magazine includes a heat-treated guide rail assembly mounted with a nail splitting plate at the end near the nail guiding plate. The nail pushing block connected to a spring is formed with three nail pushing feet adapted to a first, second, and third gaps. The nail guiding plate includes two connecting wings and forms a low-lying guide plate therebetween. Each angle between the guide plate and each connecting wing is respectively fixedly provided with a positioning step along the longitudinal direction.
