JP3013698U - File tool for circular saw - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to keep the angle when using a file depending on the file tool for a circular saw to be 45 to 50, and to have the device also function as a clam ejector. [Structure] A horizontally elongated V-shaped recess is formed in the center of a horizontally elongated metal plate, and metal plate strips are attached to both ends of the recess, and a mountain-shaped projection is provided above the strip to form an annular passage. However, a cylindrical file and a rectangular tube file can be inserted into and removed from the annular passage, and one end of the metal plate is used as the set-out portion, and when using the file, the end of the set-out portion is the side of the circular saw. Since it is in contact with, the angle of the file can be kept constant at 45 ° to 50 °.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a file device for a circular saw, which can be used as a file, can be used as a set-out portion, and can keep a constant angle when using a file.

[0002]

[Prior art]

 Conventionally, the circular saw file and the set portion are separate devices. In addition, there was no file tool to keep the angle constant when using.

[0003]

[Problems to be solved by the device]

 The file for the circular saw and the set-off portion were inconvenient because separate tools were used, and it was inconvenient because the file could not be kept at an appropriate angle (45 ° to 50 °) when used. The challenge was to make this inconvenience a convenient tool.

[0004]

[Means for Solving the Problems]

 As described in detail in the claims, a horizontally elongated V-shaped recess is formed at the center of a horizontally elongated metal plate, and metal plate strips are additionally provided at both ends of the metal plate to insert and remove a file. One end of the metal plate was used as a set-out portion. As the file, a round file and a square file are used. A round file is suitable for cutting grass because it sharpens the blade of a circular saw, and a square file is suitable for cutting the grass by blunting the blade of the circular saw.

[0005]

[Action]

 Insert a round file or a square file into the file device of the present invention, and use it by sandwiching the circular saw with both legs of the set, so one of the legs of the set is in contact with the side of the circular saw. Can be maintained at a certain suitable angle (45 ° to 50 °).

[0006]

【Example】

 It will be described with reference to the drawings. A horizontally long V-shaped recess (2) is formed in the center of a horizontally long metal plate (1), and metal plate strips (3) are attached to both ends of the metal plate (1) to form a horizontally long V-shaped recess ( At the metal plate strips (3) at both ends of 2), chevron-shaped protrusions (4) are formed on the upper side. The V-shaped recess (2) is joined to form an annular passage (10) so that the cylindrical file (5) and the square tubular file (6) can be inserted and removed. The end portion of the file is referred to as the set-out portion (7). In this drawing, the cylindrical file (5) and the square tubular file (6) are both ends.

[0007]

[Effect of device]

 You can use either a cylindrical file or a square file, and if you use a file with this device, one end of the set-off portion is attached to the side of the circular saw, so the angle when using the file is 45 ° to 50 °. It is easy to keep constant. In addition, the circular saw blade part can be corrected to the right side and the left side alternately by using the set portion. Use a cylindrical file to mow the grass. Use a square file when cutting grass.

Claims (1)

[Scope of utility model registration request] 1. A horizontally elongated V-shaped recess is provided at the center of a horizontally elongated metal plate, and metal plate strips are attached to both ends of the metal plate. In this case, a mountain-shaped convex portion is formed on the upper side, and a mountain-shaped convex portion on the upper side and a V-shaped concave portion on the lower side are joined to form an annular passage. A filer for a circular saw, which has a structure in which the metal plate can be inserted and removed, and one end of the metal plate serves as a set-out portion.
