Laser device battery powered, which shows the cutting path to get equal portions of a cake, pizza or similar food

A laser device battery powered, which shows a cutting path to get equal portions of a cake, pizza or similar foods, comprising:

• A small box-shaped support (3), provided with an interlocking hole (7) in its lower part, for the insertion of a rod (8) that holds it up when an other extremity of the rod is positioned in a central part of a cake (10), pizza or similar foods (11), to be divided into equal portions and, always in a lower part of said small box-shaped support (3), there are grooves (9) from which it is emitted a light beam generated by a laser or a set of lasers (6);
• a laser or a set of lasers (6) included inside the small box-shaped support (3), having a beam of light (13) towards the direction of the rod (8) inserted in the center of a cake (10), pizza or similar foods (11), said laser or a set of lasers (6) emit a laser light beam (13) on the top surface of the cake (10), pizza or similar foods (11), said laser light beam (13) is showing a cutting path to obtain equal portions of a cake (10), pizza or similar foods (11);
• a circuit (4), connected to a laser or a set of lasers (6), programmed with an algorithm which allows to change the equal number of portions or a shape of the cutting path for dividing into equal parts a cake (10), pizza or similar foods (11) by means of one or more command buttons (2);
• a display (1) positioned on the small box-shaped support (3), on a side opposite to the rod (8) insertion side, which displays the number of portions a user wants to get from the cutting path to obtain equal portions of a cake (10), pizza or similar foods (11);
• a battery (5), included inside the small box-shaped support (3), which supplies electric power to a circuit (4), the laser or the set of lasers (6) and the display (1).
