The field of application is to prevent the cutting groove from falling off due to vibration or the like.

中にまぎれて紛失することが多い欠点がある。(Prior art) As shown in Fig. 5, the saw blade c cuts into the pipe P from the outer periphery, and as the cutting progresses, the cutting groove, which increases in depth, is closed by the elasticity of the pipe P and becomes narrower. It is well known that one or more wedges a are driven into the pipe to perform the cutting operation in order to prevent the pipe cutting resistance from occurring on the blade c, making the cutting difficult or impossible. However, the wedge a is so-called wedge-shaped and is held by the friction caused by the elasticity of the pipe P that tries to close the cutting groove, so the wedge a is used as the cutting edge of the pipe P where the cut is started by the saw blade c. When driving into the cutting groove from the side, the pipe P
When it loses its elasticity, it easily falls off, and it has the disadvantage that it often gets lost in the soil when digging a hole and cutting a pipe buried underground.

2 is a magnet in which an inverted V-shaped groove 3 is formed in the center of the lower surface corresponding to the pipe P, and joining protrusions 4 are provided on both sides of the groove. Reference numeral 5 denotes a wedge projecting from the central top 3a of the inverted V-shaped groove 3 to the lower surface of the magnet 2, and is parallel to the direction of the top 3a of the inverted V-shaped groove 3. The wedge 5 has a degree of protrusion from the lower surface of the magnet 2 that is approximately equal to the thickness of the saw blade 6.

The lower surface of the magnet 2 is brought into contact with the outer periphery of an iron-based pipe P and is attracted to the pipe by magnetic attraction. The joining protrusions 4, 4 facilitate magnetic joining and separation of the wedge 5 to the pipe P on both sides.

て人為的に外すまで付着するものである。(Effects) The pipe cutting wedge of the present invention has the above-described structure and action, and when the wedge 5 is driven into the cutting groove 7 of the pipe P by the saw blade 6, the joining protrusions 4, 4 on both sides of the wedge 5 of the magnet 2 are connected to the cutting groove 7 of the pipe P. The pipe P is attracted to the outer periphery of the pipe P by magnetic force, which facilitates magnetic attraction and separation, and the depth of the cutting groove 7 increases as cutting progresses, and the elasticity of the pipe P to close the cutting groove 7 decreases. Or even if the cutting groove 7 widens, the wedge 5 is held against the pipe P by the above-mentioned adsorption force of the magnet 2.
The wedge 5 does not fall off and remains attached until the wedge 5 becomes unnecessary and is manually removed.

の効果を持つ。 In the present invention, the wedge 5 driven into the cutting groove 7 is held attached to the pipe P by the magnet 2, and the saw blade 6 is inserted from the side of the pipe P.
Wedge 5 is also effective for cutting pipes that are often driven into the side.
It has the advantage that it will not be lost even when cutting pipes in a dark hole in the earth, and it can be easily magnetically attracted and peeled off.
