issue). This stone cutting device was developed for the machining of a fairly thick stone work, and the target work can be moved and adjusted in the axial direction of the beam by an adjuster mechanism, and the rotating wheel blade of the stone cutting device can be adjusted. It was necessary to adjust up and down with the up-down mechanism.

Therefore, while the stone cutting device developed earlier can process thick stone work, it requires many mechanisms such as an advancing / retreating adjuster mechanism and an up / down mechanism, so the entire device is inevitably large. Inevitably, the weight has become heavy and the cost has also become high.

By the way, in the recent construction of high-rise buildings, an inexpensive stone cutting device that can easily bring it upstairs and stone the stone work there is needed. The stone material must be carried on a high-floor high-rise floor and vertically cut, cross-cut, and diagonally cut to form the stone material in the required shape. Since it is too heavy and cannot be cut diagonally, it is inconvenient as a working device for high-rise buildings. For this reason, in the past, for masonry in high-rise buildings, the stone material was formed into the required shape below and carried up to the upper floors, or a skilled mason at the construction site on the upper floor where masonry is required. The only way to do it was by hand.

The present invention has been made in view of the above-mentioned circumstances.
You can easily bring stones into the construction site such as paving stones or on the floor of a high-rise building to cut stones vertically, horizontally, diagonally, and at low cost, lightweight and small type disassembling and assembling stone cutting It is a technical object to provide a device.
