Abstract

(57) [Summary] [Purpose] The purpose is to make it possible to use an auxiliary tool for cutting wood even on a wide plate material. A wood cutting auxiliary tool characterized in that a saw blade supporting portion is arranged slidably with respect to a guide rail, and the saw blade supporting member moves along with the cutting.

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to improvement of a wood cutting aid used for cutting wood with a saw.

[0002]

[Prior Art]

 When you need to perform a precise cutting process on wood, or when an operator who is not accustomed to cutting with a saw performs cutting work on wood, set the saw blade entry angle and saw blade. A jig is used to keep the moving direction of the tool constant, but with the tools that have been used in the past, the base of the auxiliary tool should be pressed against the corner of the timber. In general, the structure is such that the cutting work is carried out while holding it by and inserting the saw blade into the saw blade guide part formed on the jig.

[Problems to be solved by the device]

 However, the wood cutting aid having the conventional configuration is premised on the case where a relatively thin square piece such as a frame is cut, and therefore, when cutting a wide plate material. Has the drawback of being useless. In other words, there is a problem that it cannot be used at all for wood with a width that is greater than the width of the saw blade. The present invention relates to an auxiliary tool for cutting wood, and seeks to eliminate such drawbacks found in conventional ones.

[Means for Solving the Problems]

 This invention can be applied to a wide plate material by configuring the supporting portion of the saw blade to freely move on the guide fixed to the wood as the saw moves. Is to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, an auxiliary tool main body 1 includes a guide rail 2 that can be attached to and detached from a wooden piece 12 and a guide rail 2 thereof. In contrast, the saw blade supporting member 6 is arranged so as to be slidable along its axial direction, and the side portion of the saw blade supporting member 6 projects from the side portion of the guide rail. This is a schematic structure in which a saw blade insertion groove 4 that is inserted from below is formed in the protruding portion of the support member 6. That is, as shown in FIGS. 1 to 4, the guide rail 2 is composed of an elongated member having an “H” -shaped cross section, and one end of the guide rail 2 has an edge part of wood. A hooking member 3 for hooking is attached in a rotatable state, and a fixture 5 having a hole 14 having a shape corresponding to the cross-sectional shape of the guide rail 2 at the center is provided on the guide rail 2. By inserting the guide rail 2 into the hole 14, the guide rail 2 is slidably arranged, and by rotating the tightening knob 7 attached to the upper portion of the fixture 5, the guide rail 2 can be moved. It has a structure that can be fixed at any position. As shown in FIGS. 1 to 4, the saw blade supporting member 6 has a notch 13 at the base portion into which the guide rail 2 can be inserted, and a gap enough to allow the saw blade 11 to be inserted at its side portion. Since the groove 4 is formed from the lower side to the upper side, and the guide rail 2 can be inserted into the notch 13, the saw blade supporting member 6 as a whole can freely move on the guide rail 2. The groove 4 into which the saw blade 11 can be slid and moved is located slightly outside the side edge portion of the guide rail 2. Although the auxiliary tool according to the present invention has the above-described structure, when using the auxiliary tool, as shown in FIG. 1, the hanging member 3 is hung on the edge portion of the wooden piece 12 and the fixing tool 5 is attached to the wooden piece 12. On the other hand, it is fixed by pressing it against the other edge, and then the saw blade 11 is inserted into the groove 4 formed in the saw blade supporting member 6 and the entire saw 9 is moved back and forth. is there.

[Effect of the device]

 The wood cutting auxiliary tool according to the present invention has the above-mentioned structure, and has an advantage that it can perform accurate cutting work even on a wide wood plate. That is, in the wood cutting auxiliary tool according to the present invention, the guide rail 2 is fixed in a state of being along the planned cutting position in the wide wood as described above, and the saw blade support member 6 is provided along the guide rail 2. Since it is configured to be moved, by attaching a contact member 15 having a shape slightly larger than the width of the saw blade insertion groove 4 in the upper direction of the saw blade in advance, the saw blade is moved along with the movement of the saw blade 9. There is an advantage that the supporting member 6 also moves, and an accurate cutting operation to a predetermined position can be performed on any wide wood.
