Description

[Detailed Description of the Invention] The present invention relates to a saw that can be used extremely conveniently for cutting plastic pipes, plastic plates, etc. used for water pipes, etc.

Next, the details will be explained with reference to the illustrated embodiment. In FIG.
A letter-shaped notch 3 is provided.

In FIGS. 2 and 3, reference numeral 4 denotes a handle made of hard plastic, etc., and one end of the saw blade body 1 is inserted into the sheath 5 of the handle 4 at a position corresponding to the notch 3 of the handle 4. When the mounting screw 7 is screwed into the mounting hole 6 drilled in the saw blade body 1, the notch 3 of the saw blade body 1 is locked to the mounting screw 7, so the handle 4 can be mounted and removed very easily. Moreover, since the notches 3 are provided at both ends of the saw blade main body 1 as described above, push-cutting and pulling-cutting can be easily performed by changing the mounting positions of the ends, which is convenient. In this case, for example, if the working space is wide and the part of the tooth 2 that is close enough to your hand hits the workpiece, pulling off is convenient; if the work space is narrow and the tip of the tooth 2 hits the workpiece, then pulling off is convenient. Push-off is convenient.

In addition, burrs that are generated when cutting plastic pipes, boards, etc. with a saw must be removed because if the pipes are used as they are for plumbing, hair etc. will get caught in them and cause debris to become clogged in sewer pipes, etc. However, conventionally, two types of cutters having a conical convex surface and a conical concave surface are pressed against the tube end and rotated to remove the tube, which requires processing twice, which is time-consuming.

The saw of the present invention has a saw blade body 1 as described above.
Since a substantially V-shaped notch 3 is provided at the end of the tube, the notch 3 is cut off to form a tube end 8, as shown in FIG.
By simply rotating the tube 9 while pressing against it, it is extremely easy to remove burrs on the inside and outside of the tube end at once, and chamfering can also be done easily, making it extremely convenient to use for piping work, etc. be able to. Cut surfaces of plastic plates and the like can be deburred very easily in the same manner as pipes.

In addition, in the present invention, since the notch 3 is provided on the side of the tooth section 2 of the saw blade body 1 as described above, when cutting burrs, the hand holding the saw blade body 1 is Since the palm touches the smooth edge of the back of the saw blade body 1, the teeth 2 do not come into contact with the palm and dig into the palm, as would be the case if the notch 3 was provided on the back of the saw blade body 1. Therefore, the notch 3 can be pressed against the tube end with a sufficient pressing force, and the processed end can be finished quickly and easily. In addition, in the present invention, as described above, the notches 3, 3 are provided at both ends of the saw blade body 1, and one end of this is inserted into the sheath 5 of the handle 4, and the cutouts 3, 3 are inserted into the notches 3 of the handle 4. Since the mounting screw 7 is screwed into the mounting hole 6 drilled at the corresponding position and the notch 3 is engaged with the mounting screw 7, the handle 4 can be easily mounted by using the notch 3. It is easy to remove, and the saw blade body 1 can be easily replaced when the teeth 2 are worn out. In addition, pushing and pulling can be performed by changing the mounting position of the handle 4 as described above. In either case, this saw has practical effects such as being extremely convenient because it can be deburred without changing the mounting position after cutting.
