Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cutting machine in which a saw blade is attached and cut, such as a reciprocating saw , with a single blade holder having a width smaller than a standard saw blade and a standard saw blade.
Saw blade attachment of cutting machine that can attach thin thin saw blade
It concerns the device .

[0002]

2. Description of the Related Art The prior art will be described with reference to FIGS. In the conventional saw blade holder, the saw blade holder 1 having the concave portion 10 into which the mounting portion of the saw blade 4 can be fitted is a reciprocating saw 8.
Is attached to the plunger 9 by bolts 6,
As shown in FIG. 4, the standard saw blade 4 was sandwiched between the saw blade holder 1 and the plunger 9, and the bolt 6 was tightened to hold the saw blade 4.

[0003]

In the conventional saw blade holder 1, a plurality of saw blades 4 having different mounting part shapes could not be held by one saw blade holder 1. Therefore, in order to hold the saw blade 4 having a different mounting portion shape, another inexpensive saw blade holder must be prepared, and the saw blade holder 1 attached to the plunger 9 must be replaced with another one. There was a problem that had to be. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a mounting device which can mount and hold two or more types of saw blades having different mounting portion shapes with a simple structure.

[0004]

The above object is achieved by the above-mentioned saw blade holder.
Smaller than the width of the recess of the saw blade holder on the saw blade mounting surface of the holder
Removably mount a plate with a narrow recess.
The thin and thin blade is sandwiched by the rate and plunger.
It is achieved by the mounting Keru as crowded look.

[0005]

The saw blade mounting apparatus constructed as described above can mount and hold at least two types of saw blades having different mounting portions by simply attaching and detaching a plate corresponding to the saw blade to be used.

[0006]

DETAILED DESCRIPTION FIG. 1, the present invention employs a reciprocating saw in Figure 2
1 shows an embodiment of a saw blade mounting device . 1 and 2 show the mounting
The width and thickness of the part is greater than the width and thickness of the mounting part of the standard saw blade 4.
An example in which a small and thin thin saw blade 5 is attached is shown. The saw blade holder 1 is the same as the conventional saw blade holder described above ,
To be able to hold a standard saw blade 4, a standard saw blade 4
A concave portion 10 having a width to be fitted with the mounting portion is provided.
Plate 3 recess 11 can hold Rutotomoni the thin saw blade 5 having a wear Datsuka ability width into the recess 10, has a through-hole 7 is provided with further bolts <br/> bets 6 penetrates You.

Next, a case where two types of saw blades having different mounting portions, such as the thin saw blade 5 and the standard saw blade 4, are mounted on the reciprocating saw 8 will be described. When the thin saw blade 5 is to be mounted, the plate 3 and the thin saw blade 5 are sandwiched between the plunger 9 and the saw blade holder 1, and the thin saw blade 5 is mounted and fastened by tightening bolts 6. I do. In this case the plate 3 is fitted tightly against both the holder main body 2 and thin saw blade 5.

Next, when the standard saw blade 4 is to be mounted, the standard saw blade 4 can be mounted in exactly the same manner as in the related art by removing the plate 3.

[0009]

[Effect of the invention] above in accordance with the present invention. Thus removably attached a plate having a different saw blade retention feature and the saw blade holder in the recess of the saw blade holder,
It is possible to mount and hold two or more types of saw blades having different mounting part shapes with a simple structure without preparing saw blade holders for the number of saw blades. In addition, it is easy just to attach and detach the plate
Can be mounted by operation, improving operability
You.
