<p>A safety mechanism for a fastening machine (10) of the type wherein fasteners are ejected along a guide channel (23), out of the device and into the required fastening position, by means of a driver (20) with an automated actuating mechanism. A mechanical blocking element (33), normally interposed between the driver and the fastener in the guide channel, prevents said fastener being struck by the driver. This blocking element can be moved to an inoperative position, allowing the driver to strike the fastener out of the guide channel, by an actuator which projects from the device adjacent the exit from the guide channel but can be pushed into the device to deactivate the blocking mechanism when the fastening machine is placed against a substrate into which a fastener is to be inserted.</p> |
