Apparatus and system for securing a cutting device

A system comprising a plurality of separately usable and interchangeable components for cutting, sawing or slicing through objects, the system comprises:

• a first component with a cutting wheel having a central drive shaft,
• at least one second component with a circular saw blade with a centerless driving,
• a holder and a securing device which is common to both the first and second components and which has a rear arm and a front arm, the rear arm having a free, rear end, that can be connected to either component at a first hinge,
• a first spindle having a first extension piece being arranged at said first hinge, the rear arm being rotatable about a first axis of rotation parallel to the center of rotation of the cutting wheel or the circular saw blade, respectively, and the rear arm having a front end rotatably connected, by means of a toggle joint, to a rear end of said front arm, the front arm having a front, free end rotatably connected about a second axis of rotation at a second hinge for anchoring the holder and, thus, the respective component, on the object which is to be cut or sawn,
• whereby the first component with the cutting wheel or the second component with the saw blade is capable of being displaced relative to the said object at right angles to the first axis of rotation during turning of the arms at the said first and second hinges and at the said toggle joint, centerline of the said first axis of rotation intersecting a plane of rotation of the cutting wheel or the circular saw blade, respectively, at a point between the center of rotation of the cutting wheel or saw blade and a periphery of the cutting wheel or saw blade, and at least two exchangeable securing devices are provided, each securing device having at least one spindle attachment which can accommodate a second extension piece on a second spindle arranged at the said second hinge at the front end of the front arm of the holder, which second extension piece extends outwards from said second spindle in an opposite direction compared to the first extension piece of the first spindle at the first hinge.
