ABSTRACT:
An apparatus forming a portable, hand-operated machine (1, 1', 1"), having a circular cutting wheel (4) or saw blade (4") which is rotatable about a center of rotation (5, 5"), comprises a double-armed holder (9) with a rear arm (20) which, at its rear, free end (27), is connected to the machine at a first hinge, rotatable about a first axis of rotation (18, 18a, 18b, 18") parallel to the center of rotation of the cutting wheel or the saw blade, and, at the other end, is connected rotatably, by means of a toggle joint (22), to a front arm (21) which in turn is connected rotatably, at its front, free end, to a securing device about a second axis of rotation at a second hinge, for rotatable anchoring of the holder and, thus, of the machine on the object which is to be cut or sawn. The center line ( 18, 18a, 18b, 18") of the said first axis of rotation intersects the cutting wheel, the saw blade or the space possibly present inside the saw blade, if the latter is annular, at a point between the center of rotation of the cutting wheel or saw blade and the periphery. The invention also relates to a system in which the apparatus can be included as a component, and to a securing device included in the system.
