Abstract
The invention concerns an actuator ( ) comprising a pre-stroke rod ( ) which can be fixed to the tool body, for example soldering pliers. Thus by pressurising the pre-stroke chamber ( ) the working rod ( ) for closing the pliers can be brought into an intermediate small opening position, the working piston ( ) and the amplifying pistons ( and ) remaining retracted in the actuator. Since the rod ( ) can then be locked relative to the actuator body ( ), pressurisation of the working chamber ( ) and the amplifying chambers ( and ) will then cause the working rod to be extracted ( ) and the soldering pliers to be closed without any recoil from the actuator body.
