Abstract:
A tacker for a fastener, with which a tacking plunger is drivable by a drive unit and expels the fastener via a muzzle tool, with a switch device comprising a switch plunger, for actuating the drive unit which has a pivotably mounted release lever for actuating the switch plunger, with a contact feeler which can be actuated on contacting a workpiece, which is movably mounted on the muzzle tool and which is pretensioned by a spring into an idle position in which it protrudes beyond the muzzle tool, and with a safety device which is arranged between the contact feeler and the switch device and which has a transmission device, for preventing a release of the drive unit when the contact feeler is in its idle position, said safety device comprising a slide element which is movably mounted on a side of the release lever directed towards the switch plunger and which is coupled to the transmission device and is movable with the release lever relative to the transmission device wherein in the idle position of the contact feeler, the side element is located in a position in which the switch plunger on actuation of the release lever remains unactuated, and on actuation, of the contact feeler, the side element is displaced into a position in which the switch plunger is actuated on actuation of the release lever, wherein the transmission device between the contact feeler and slide element comprises a flexible strip element, wherein the switch device is arranged in an inner angular region between a housing head and a housing grip directed laterally away from the upper region of said housing head, wherein the pivoting axis of the release lever is located near to an angle corner and wherein the flexible strip element includes a flexible strip section that is linked around on an inner end of the release lever and further includes a region of increasing wall thickness that is connected to the flexible strip section and that is guided along the housing head to the muzzle tool.
