Abstract

(57) [Problem] To provide a file tool for a circular saw, which can easily perform a polishing operation at a polishing angle of a circular saw blade suitable for a material to be cut with only one cylindrical file. SOLUTION: In the file tool for circular saw, the joining of one side 2 of the triangular bar-shaped grooved rod 1 and the tube 4 is performed at a position where polishing can be performed to 12 and the joining of the other side 3 and the tube 4 can be performed at 13 position. Two pieces were joined at an interval where they could be used in common, even if the polishing angles of the saw blades were different.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a file cutter for a circular saw, in which the polishing angle of the cutting edge of the circular saw can be changed with only one cylindrical file.

[0002]

[Prior art]

 Conventionally, a plurality of irregularly shaped files were used to change the grinding angle of the circular saw blade. I applied for and registered a utility model on May 10, 1995. Registration No. 3013698.

[0003]

[Problems to be solved by the invention]

 In the conventional circular saw file tool, the circular saw blade suitable for cutting grass has a different grinding angle from the circular saw blade suitable for cutting grass, and the circular saw blade suitable for cutting wood. There was an inconvenient problem that a plurality of irregularly shaped files had to be used to grind the cutting edge.

[0004] In the circular saw file tool of the present invention, even if the grinding angle of the circular saw blade suitable for cutting grass is different from that of the circular saw suitable for cutting shiba wood, a single blade is used. The purpose is to be able to grind the edge of a circular saw suitable for the material to be cut using a cylindrical file.

[0005]

[Means for Solving the Problems]

 In the file tool for circular saw of the present invention described in the claims, one side of the triangular bar-shaped grooved rod is provided with a groove of an L-shaped recess, and the other side is a groove of a V-shaped recess. A pipe with a groove is provided.The two pipes can be shared by two sides, and two pipes are connected at an interval. The end of the pipe is a handle, and a cylindrical file can be inserted into and removed from the pipe. In addition, a screw can be attached to the pipe and the cylindrical file inserted can be fixed with screws. The triangular rod-shaped grooved rod is joined to the tube at the side of the groove of the L-shaped recess at a position where the grinding angle of the blade of the circular saw can be polished to 40 ° to 45 ° which is suitable for cutting grass. The other side of the grooved rod has a V-shaped concave groove with a concave groove. The groove is joined to the pipe. The grinding angle of the circular saw blade is 70 ° to 75 °, which is suitable for cutting wood. It was a place where the two sides could share it where possible. The grinding angle of the cutting edge of the circular saw varies depending on the material to be cut, and one side of the triangular bar-shaped grooved rod is an L-shaped recess and the other side is a V-shaped recess in order to facilitate selection of a suitable grinding angle for the material. A convenient structure that can easily grind the edge of a circular saw that is suitable for cutting grass or shiba with only one cylindrical file, with a groove formed by adding a concave groove to the groove.

[0006]

[Embodiment of the invention]

 Inserting a cylindrical file into the pipe of the circular saw file instrument constructed as above and fixing it with a screw.The sharpening of the cutting edge of the circular saw from two sides of the triangular bar-shaped grooved rod is suitable for grass or bush. The edge of the groove of the L-shaped concave portion or the groove of the V-shaped concave portion provided with a concave groove is stably brought into contact with the blade portion of the circular saw to grind the cutting edge.

[0007]

【Example】

 With reference to the drawings, a cylindrical file 6 is inserted into a tube 4 joined to a triangular bar-shaped grooved rod 1 in FIG. The triangular rod-shaped grooved rod 1 is selected from the side of the groove 2 of the L-shaped recess or the side of the groove 3 in which the groove of the V-shaped recess is provided with a concave groove, and is a state shown in FIG. The edge 10 of the groove of the L-shaped concave portion on one side of the triangular bar-shaped grooved rod 1 or the edge 11 of the groove provided with a concave groove in the groove of the V-shaped concave portion is stably contacted with the blade portion 8 of the circular saw 7 to form a circle. The saw blade 9 is polished.

[0008]

[Effect of the invention]

 As described in detail, using the file cutter for circular saws of the present invention makes it easy to select the sharpening angle of the circular saw blade that is suitable for cutting grass. It was made correctly and easily with the cylindrical file.

[0009]
