Embodiment Construction

[0019] The hand tool now described is a so-called air nailer, i.e. it comprises a combustion chamber in which a mixture of fuel (here gaseous fuel) and oxidant (air) is ignited to propel the plunger or piston 1 forward , pushing the fastening elements (here nails) into the support material in turn. Said piston 1 comprises a head 2 and a rod 3 . Said head 2 is mounted in a cylinder 4 and can translate in translation until it abuts a baffle 5 under the action of ignition of the mixture. Before ignition, the combustion chamber is closed by moving a cover 6 integrally connected with said cover 6 , which is extended by an arm 7 fixed to a yoke 8 . Said piston shaft 3 is mounted translatably in a cylinder 9 extending forward together with a needle guide rod 10, which is telescopic and freely translatably mounted in the cylinder 9, and during pre-firing, A nail is housed in the needle guide bar 10 . Cover yoke 8 is slidably mounted around cylinder 9 . The tool comprises a knurled...

Abstract

#CMT# # / CMT# The tool has a driving rod (3) driving a fixation element in a support material, and a buffer guide (10) that is freely mounted in translation. Overrunning adjusting unit has an adjusting roller (11) with a roller shaft (15) arranged for support against the buffer guide to push the buffer guide toward a front under rotation of the roller. An anterior end of the roller shaft has a posterior support edge (18) against a cage clamp (8). #CMT#USE : # / CMT# Hand fixation tool i.e. gas nailer and staple gun. #CMT#ADVANTAGE : # / CMT# The fixation tool is simple in structure. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows an axial sectional and perspective view of a hand fixation tool. 3 : Driving rod 8 : Cage clamp 10 : Buffer guide 11 : Adjusting roller 15 : Roller shaft 18 : Posterior support edge.

Description

technical field [0001] The present invention relates to a hand-held fastening tool of the type such as a nailer or binding tool. Background technique [0002] Such a tool comprises a propulsion engine arranged to drive a piston (or weight) with a rod, under combustion of fuel, more specifically gas or powder, driving the fastening element into the support material. [0003] In the front of the tool there is a fastener guide, in which the fastening element to be driven is placed. Firing occurs only after the tool passes the fastener guide against the support material. [0004] The penetration depth of the fastening element into the support material depends on the length of the fastening element and the length by which the piston rod protrudes outside the fastener guide at the end of firing. Therefore, it should be understood that it is desirable to adjust the drive depth to a variable where, exactly, the length of the fastening element, the need for the head of the fastenin...
