Abstract
The invention relates to a fastening tool comprising a handheld housing with a piston element (), which is received in the housing and which can be moved in a driven manner, for transmitting energy to a fixing element (). The piston element () is guided in a cylinder () and can be accelerated towards the fixing element () by a drive force, and the piston element () can be held in a starting position by a magnetic force of a retaining element (). The retaining element () has a first magnetically conductive stop () and a second magnetically conductive stop (). The magnetic stops () are connected by a magnetically conductive counter piece () arranged on a piston element when the piston element () is being held, and excitation magnet () is arranged between the magnetically conductive stops ().
