BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saw.

[0002]

2. Description of the Related Art Conventionally, there is a saw that folds a saw plate into a handle when not in use and a saw that replaces the saw plate with a new one by cutting the blade, etc. I didn't have a saw that could be broken or folded.

That is, the saw plate was attached by a screw, but it had to be attached and detached using a means such as a screwdriver, so that replacement was very troublesome.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a saw in which the saw plate is easily attached and detached and folded by one-touch operation, and the handling thereof is easy.

[0005]

According to the present invention, a through hole is provided at a base portion of a saw plate, a through hole is provided at the base portion of the saw plate, and a through hole is provided at the end of the base portion. Insert a screw between the through holes penetrating to the left and right sides of the front end of the body, insert a bullet inside the head of this screw and install a seat plate around it, and the tip of the inner leg of this seat plate Is inserted into the through hole on one side of the board, and the end of the screw is screwed into the inside of the knob provided on the handle, and the through hole of the saw plate and the through hole of the board installed inside the handle on the screw. An engaging member having an outer peripheral portion that is inserted through the outer diameter of the engaging member and a tube portion having an outer diameter smaller than the outer peripheral diameter of the engaging member contact the tip of the pressing collar that is inserted through the through hole of the base plate and the through hole of the saw plate with the back surface of the engaging member. Consists of

Further, according to the present invention, a screw is inserted between a through hole provided in a substrate provided in the handle and a through hole penetrating to the left and right sides of the front end portion of the handle, and the through hole of the substrate and the saw are provided on the screw. An engaging member having an outer peripheral portion that is inserted into the through hole of the plate, and a pressing collar that has an outer diameter smaller than the outer diameter of the engaging member and that is inserted into the through hole of the substrate and the through hole of the saw plate are provided, and the sliding groove of the substrate is provided. A slider is provided on the upper surface of the sliding plate installed in the substrate, an extension bullet is provided at the rear end of the sliding plate, and a front end protrusion provided on the front side of the sliding plate is attached to the saw plate base. It comes close to and separates from the upper side.

[0007]

When the saw plate is in use as shown in FIG. 1, the engaging element on the screw which is integrated with the knob on the side surface of the handle body is stretched by the ammunition machine to extend the saw plate from one through hole of the substrate. After entering the through hole, it stops at the other through hole of the substrate (see FIGS. 3 and 5).

Therefore, when the saw plate is to be replaced with a new one, the thumb is put on the pick and pressed. Then, since the protrusion inside the knob pushes the rear surface of the pressing collar on the screw, the engaging element is pushed out from the other through hole of the board and the through hole of the saw plate, and the other through hole and saw of the board. Instead of the passage of the plate, the tube portion of the pressing collar is located. Since the outer diameter of this pipe part is smaller than the diameter of the saw plate, if the saw plate is pulled in this state, it will be separated directly from the hole of the saw plate base and the saw plate will be pulled out (Fig. 4, Fig. 6, Fig. 6). 7).

Next, when the saw plate is in use as shown in FIG. 1, the slider on the upper surface of the handle body is stretched by the ammunition,
It is positioned by being pressed to the frontmost side of the opening of the handle and the sliding groove of the sliding plate, so that the front end projection of the sliding plate inside the substrate presses the upper side surface of the long arm part of the saw plate base. This is suppressed (see FIG. 8).

Further, in this state, the engaging element on the screw which is integrated with the knob on the side surface of the handle body is extended by the ammunition machine from one through hole of the substrate into the through hole of the saw plate and further on the other side of the substrate. It stops at the through hole.

Therefore, when the saw plate is rotated to be folded, the thumb is placed on the slider and slid backward. Then, since the slider hits against the opening of the handle and the rearmost side of the sliding groove of the sliding plate, this causes the sliding plate in the substrate to move rearward, and the front end projection of the sliding plate extends to the length of the saw plate base. Separate the top side of the arm to release the restraint (see FIG. 9).

In this state, the saw plate may be rotated downward to be housed in the concave groove portion of the handle. At this time, the hook portion of the sliding plate engages with the hooking portion of the saw plate to fix the storage of the saw plate in the handle body (see FIGS. 10 and 11).
