Description

[0001] Portable Cutting Apparatus [0002]

More particularly, the present invention relates to a portable cutting device, which is easy to carry, and is easy to change direction when cutting a cutting object such as various metal plates, so that it is possible to continuously cut a straight line as well as a curved line.

2. Description of the Related Art In general, various cutting apparatuses for cutting an object to be cut have been proposed, including a cutting apparatus equipped with a saw blade, and a rotating disc-type cutting apparatus.

Further, when cutting various kinds of objects to be cut, particularly cutting a metal plate material, the saw blade type cutting device can be cut only in a straight line, and it is not possible to change the direction or to cut in a curved shape.

The disk type cutting device is also an electric type in which a disk is rotated by a motor to perform a cutting operation. However, this is also impossible when switching the cutting direction.

Therefore, in recent years, the cutting operation can be performed while switching the cutting direction freely through a cutting device using a laser beam or the like. However, such a laser beam cutting device is expensive and difficult to carry, .
