[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutting machine such as a gas burner, for example, a cutting machine adapter for accurately cutting a reinforcing bar in a cutting direction.

[0002]

[Prior art]

 BACKGROUND ART Cutting work for cutting steel materials such as long reinforcing bars and steel bars to a predetermined size with a cutting machine such as a gas burner is constantly and frequently performed in factories and construction sites. The cut steel material is generally used as it is, although the cut part may be processed and modified in a later process. Therefore, it is necessary to cut along the correct cutting direction at the cutting position. Correct cutting is possible by applying a flame of a gas burner to the cutting point and moving the flame along the cutting direction, but this work requires a considerable amount of skill, and accurate cutting cannot be done by manual cutting alone. It is normal. Therefore, conventionally, a ruler with a rail is fixed to a steel material and the cutting work is carried out along the rail, especially when cutting into a disc, a cutting machine is supported by a compass. Scraping tools were used.

[0003]

[Problems to be solved by the device]

 The method using the above ruler has a problem in that it is troublesome to attach and detach the ruler, and it is difficult to cut steel material such as a reinforcing bar. Also, the compass shape is applied only to circular cutting and is not general.

The present invention solves the above problems, and even an unskilled person can accurately cut an object to be cut along the cutting direction, is easy to handle, and can shorten the cutting work time. It is intended to provide an adapter for a breaker.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is an adapter for holding an object to be cut and holding a cutting machine at a cutting position, the adapter being in contact with the outer circumference of the object to be cut and holding the object to be cut. Holding tool, a support main body that supports the cutting machine in an attachable / detachable manner, a rotating tubular body that is rotatably supported by the supporting main body, and a bridge installed between the rotating tubular body and the holding tool. An adapter for a cutting machine is provided which is provided with an arm member fixed to both of them and a spring member stretched between the arm member and the support body side. More specifically, the arm member is formed by superimposing at least two upper and lower flat plates, and is formed to adjust the overlapping length to make the arm length variable. Further, a protrusion member is provided on the arm member side, and a bracket having a pressure contact surface with which the protrusion end of the protrusion member is pressure contact engaged when the arm member is rotated is fixed to the support body side. It is characterized by Further, the arm member is provided with a holding means for holding the upper and lower flat plates at a predetermined overlapping position, and the supporting body is provided with a holding means for holding the inserted cutting machine at a predetermined position. It is characterized by that.

The object to be cut is stably held by the holder. Also, the cutting machine is fixed in place by adjusting the insertion position in the support body. Since the arm member fixed to the holder is also fixed to the rotating cylinder body that is rotatably supported by the support body, the cut object side can rotate around the support body. On the contrary, when the object to be cut is firmly held, the support body that supports the cutting machine becomes rotatable. Therefore, by rotating the cutting machine, the cutting function part (flame of the gas burner) of the cutting machine moves correctly along the cutting direction, so that a correct cutting is performed. Further, since the spring member has a function of always urging the arm member and the holding tool so as to push them toward the supporting body side, the holding tool side and the supporting body side are not displaced. Therefore, relative displacement between the object to be cut and the cutting machine does not occur.
