BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating cutter for cutting a coating on a coating pipe.

[0002]

2. Description of the Related Art Conventionally, in the above-mentioned coated cutter, a C is used to relatively insert a coated pipe in a radial direction to sandwich it.
Provided with a character-shaped holding portion, provided with a cutter blade for covering pipe cutting protruding to the holding space of the holding portion, the holding portion in a state of sandwiching the covering pipe, around the covering pipe together with the cutter blade. There was a handle for rotating.

In this structure, the rotating operation of the holding portion is performed with the handle held.

[0004]

However, according to the above configuration, when the holding portion is rotated around the cladding tube, since the rotating operation is performed while the handle is gripped, it is necessary to rotate once around the cladding tube. The handle must be grasped and changed at least once on the way, which has the drawback of poor workability.

It is an object of the present invention to solve the above-mentioned conventional drawbacks and to provide a coating cutter which can be rotated with good workability when the holder is rotated around the coating tube to cut the coating.

[0006]

In order to achieve the above-mentioned object, a coating cutter according to the present invention is provided with a plurality of holding portions for respectively radially inserting a plurality of coating pipes and sandwiching them. , A state in which one of the holding spaces of the plurality of holding portions is provided with a cutter blade for selectively cutting and moving the tube coating cutting, and the cutting blade is projected with respect to one of the holding spaces of the plurality of holding portions. A fixing tool for fixing the cutter blade at the protruding position is provided, and the operation and effect thereof are as follows.

[0007]

In other words, because of the above structure, the cutter blade for cutting the pipe covering is projected into the holding space of one of the plurality of holding parts, for example, the first holding part, and the fixing tool projects the cutting blade. The cutter blade rotates integrally with the first holding part by fixing it in position and inserting the first covering pipe into the first holding part by relative insertion and rotating the first holding part around the first covering pipe. The coating of the first cladding tube can then be cut around the entire circumference of the tube.

In this case, since the second holding portion or the like for holding the second coating pipe or the like is provided separately from the first holding portion, the second holding portion or another holding portion is provided. It can be used as a rotation operation unit of the first holding unit.

Moreover, since the second holding portion and the like are for inserting the second covering pipe and the like, a finger can be inserted into the holding space and the first holding portion can be rotated by the finger. Therefore, when rotating the first holding portion around the covering tube, it is not necessary to grip the rotation operation portion as in the conventional case.

Further, the cutter blade for cutting the pipe coating is projected into the holding space of the second holding portion, and is fixed at the protruding position by the fixing tool, and the second coating pipe is relatively fitted into the second holding portion. As in the case of the first cladding tube, the first holding portion or another holding portion is used as a rotation operation portion, and the second holding portion is rotated around the second cladding tube, so that the coating of the second cladding tube is prevented. Can be cut all around. In this way, the third
The covering tube and the like can be cut by the same operation.

[0011]

[Effect of the Invention] Therefore, when the holder is rotated around the coating tube to cut the coating, the coating can be rotated with a finger, and there is no need to grip the rotating operation unit as in the conventional case.
Moreover, for example, if the inner diameters of the plurality of holding portions are different,
It has become possible to deal with the cutting of coatings of a plurality of pipes having different diameters, and as a result, it is possible to provide a coating cutter which can save work and improve workability.
