Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an auxiliary tool used for cutting wood.

In wood processing, as shown in FIGS. 4 and 5, the work of cutting the ends of each wood at an angle of 45 degrees and joining them with the cut surfaces facing each other is frequently performed. However, if the cutting angle with respect to the wood is changed during such frame processing, the dimensions of the entire processed product are changed, and at the same time, a gap is created in each joint. It is not easy for a skilled person to accurately perform cutting work on wood at an angle of 45 degrees or 90 degrees, and it is a technique impossible for an amateur.

The present invention relates to an auxiliary tool used when performing angle cutting such as frame processing on wood, and by using it, an attempt is made to accurately perform those operations. To do.

The construction of the wood cutting auxiliary tool according to the present invention will be described with reference to the drawings. The wood cutting auxiliary tool body 1 has an "L" -shaped base at the lower portion as shown in FIGS. 1 and 2. 2 is arranged, and a guide block 5 having a saw guide groove 4 having an arrangement angle of 45 degrees or 90 degrees with respect to the longitudinal direction of the base 2 is arranged above it. Of.

That is, as shown in FIGS. 1 and 2, the main body 1 for cutting wood has a structure including a base 2 and a guide block 5 disposed above the base 2. The base 2 is formed by an "L" -shaped metal fitting having a right angled corner as shown in FIG. 1, and an opening 3 is formed in the center by cutting a side wall. The guide block 5 is formed so that the guide block 5 is perpendicular to the downward direction and is arranged at an angle of 45 degrees in the lateral direction as shown in FIGS. 1 and 2. The saw blade guide grooves 4 are arranged in an "X" shape, and the saw blade guide grooves 4 having an angle of 90 degrees are arranged on both sides of the saw blade guide grooves 4. Is arranged above the open portion 3 in Of. Therefore, during its use, as shown in FIG. 3, the lower surface of the horizontal plate portion of the base 2 is applied to the horizontal surface of the wood, and the hanging plate portion is brought into contact with the vertical surface portion of the wood by hand. While fixing
With the saw blade 7 inserted in the saw blade guide groove 4 of the required angle, the cutting work for the wood is performed.

The wood cutting auxiliary tool body 1 according to the present invention is configured as described above, and exhibits the following effects.

That is, when performing processing as shown in FIG. 4 on wood, it is necessary to combine cutting work at angles of 45 degrees and 90 degrees. The use of the auxiliary tool has the advantage that necessary cutting can be performed easily and accurately, and that there is an advantage that displacement of the cut position can be prevented.

Claims (1)

[Scope of utility model registration request] 1. A guide block 5 is arranged on the upper side of a base 2 having an abutting portion of wood on a horizontal surface and a hooking portion on a vertical surface, and the guide block 5 is arranged in the longitudinal direction of the base 2. The saw blade guide groove 4 having an angle of 45 degrees is formed so as to be in an "X" -shaped crossing state, and the "X" -shaped saw blade guide groove 4 is provided with "X" at the side portion thereof. An auxiliary tool for cutting wood, characterized in that a saw blade guide groove 4 is formed which starts from a notched end of the saw blade guide groove 4 having a character shape and forms an angle of 90 degrees with the longitudinal direction of the base 2.
