Abstract

PURPOSE: To enable easy attachment of a blade to a handle without requiring hammering the handle tail, by forming a recess on an end of a tang and a hole in an intermediate portion of the tang so that the tang may be inserted into a slit formed in the handle and connected to the handle by a stopper shaft and a fastening shaft. CONSTITUTION: A tang 3 extends from the base end of a blade 2 attached to a handle 9, having a recess on an end and a hole in an intermediate portion thereof. The handle 9 has a slit into which the tang 3 is inserted. For assembling the saw, the blade 2 is connected to the handle 9 by inserting the tang 3 of the blade 2 into the slit of the handle 9, engaging the recess with a stopper shaft 7, and then tightening a threaded fastening shaft 8 that has been loosened, into the hole of the tang 3. The fastening shaft 8 is securely tightened to clamp the tang 3, narrowing the slit of the handle 9. For replacing the blade 2, the blade 2 is detached form the handle 9 by loosening the fastening shaft 8 and pulling it out of the hole, and then another blade is connected. Thus, blade replacement can be performed simply by loosening the fastening shaft 8 alone.

合することのできる鋸を提供することを目的とする。Since the conventional saw has the above-mentioned structure, if the handle is elongated and straight, it is possible to hit the bottom of the handle and attach the blade plate to the handle. However, for example, when using a saw in a narrow place, it is possible to use a short handle because a long handle does not allow enough stroke to the front and back of the saw, but it is not possible to hold it firmly with your hand. It is convenient to use a pistol type handle as shown in the drawing. However, such a handle has a disadvantage that the handle cannot be hit with a hammer. It is an object of the present invention to provide a saw that can connect a blade plate to a handle without hitting the handle end with a hammer.

The komi 3 is provided for inserting the blade plate and the handle into the handle. A recess 4 is provided at the end of the komi 3, and a hole 5 is provided further forward than that.

ものは、本発明の範疇に含まれるものでない。The handle 1 is formed in a pistol shape so that a saw can be ground even in a narrow space. That is, the handle grip portion 9 is formed obliquely downward with respect to the length direction of the blade plate 2. However, the present invention is not limited to this, and an elongated rod-shaped handle may be used. A gap 6 is provided from the tip of the handle 1 to the middle thereof. Although the gap 6 is open at the top and bottom in addition to the tip, the gap 6 is not limited to this embodiment in the present invention, and is a hole-shaped gap in which only the tip is opened and the top and bottom are not opened. Good. Further, the width of the gap 6 is such that the blade plate 3 can be inserted into the gap 6 only by the force of the hand, and an extremely narrow width that cannot be inserted unless the handle end is hit with a hammer, It is not included in the scope of the present invention.

合には替刃式として使用することができない。A locking shaft 7 is fixed to the inner portion of the gap 6. The locking shaft 7 locks the recess 4 of the komi, and may be a rivet or a screw. A stop shaft 8 is attached ahead of the locking shaft 7. The stop shaft 8 is preferably a screw as in the embodiment, but the present invention is not limited thereto and may be a rivet. If the stop shaft 8 is a screw, the stop shaft 8 that has crossed the gap 6 will come out from it by loosening the screw, so that the blade plate 2 can be replaced, so use it as a replaceable saw. You can However, it cannot be used as a replacement blade type when it is completely fixed with a rivet.

刃板の交換に手間がかかる。When assembling the saw, the blade 3 is inserted into the clearance 6 of the handle to lock the recess 4 in the locking shaft 7, and the screw-shaped locking shaft 8 which has been loosened in advance is tightened to form the hole. The handle 1 and the blade plate 2 are connected by inserting the handle 1 into the blade 5. Since the clearance 6 of the handle is slightly wider than that of the conventional saw, it is necessary to tightly tighten the stop shaft 8 to press the komi 3 into pressure contact. When the blade plate is replaced, the blade plate 2 can be removed from the handle 1 by loosening the stop shaft 8 and coming out of the hole 5, so that another blade plate may be attached by the method described above. In the case of the replaceable blade type saw, only one stopper shaft needs to be loosened in the present invention, so that the blade plate can be easily replaced. If two holes are formed in the comb and the blade plate is joined with a screw-shaped stop shaft, it is necessary to loosen the stop shaft twice, so that it takes time to replace the blade plate.

However, since the handle and the blade plate are connected at one point, the blade plate swings around the nail simply by inserting the nail. In particular, if the clearance of the handle is opened not only at the tip but also at the top and bottom, there is nothing that regulates the swinging of the blade plate, so it cannot be used as a saw. Therefore, even with a conventional saw with eye-nail holes, the handle gap is formed extremely narrow, and the knot is inserted by inserting the komi into the handle gap before hitting the handle end. It was not possible to use a pistol-shaped handle that cannot be used.

で刃板を着脱することができる。The structure of the present invention is as described above, and the engaging shaft 7 is attached to the inner part of the handle 1 so that the recess 4 of the blade plate 2 is engaged with the engaging shaft 7. A stop shaft 8 is attached ahead of the locking shaft 7, and the stop shaft 8 is inserted into the hole 5 of the blade plate, so that the handle 1 and the blade plate 2 are connected. Therefore, since the blade plate 2 is connected to the handle at two positions, the blade plate 2 can be securely attached to the handle 1 without hitting the handle end, and the blade plate 2 does not swing during use. .
Further, since one of the two connecting points is the engagement between the engagement shaft 7 and the concave portion 4, this portion can be easily engaged and disengaged. Therefore, when a screw is used for the stop shaft 8 and the blade plate is a detachable blade type, substantially only one stop shaft 8 can be operated even though it is connected at two points. The blade plate can be attached and detached.
