Abstract
The invention relates to a multi-dimensional pipe cutter and overcomes the defect that the quality of a cutting end surface is affected as an existing pipe is clamped by way of open type point supporting to easily lead to tripping of the pipeline and deviation of a cutting track. The multi-dimensional pipe cutter comprises a grab handle and a cutting knife arranged in the grab handle; a pipe clamping device which is arranged at the front end of the grab handle comprises a drawstring for tightly holding the pipe, and the drawstring and the grab handle are detachably connected and the length of the drawstring can be adjusted to fit pipes in different diameters. The drawstring, which is of a flexible structure, can be bent, and the bent drawstring bypasses the pipe and tightly holds the pipe. The length of the drawstring tightly holding the pipe changes along with perimeter of the pipe, so that the multi-dimensional pipe cutter can be suitable for the cutting requirements of pipes in different specifications, and meanwhile, the pipe can be further compressed by way of tightly holding the pipe, so that the adaptability of the pipe cutter is improved; moreover, the holding force of the drawstring which tightly holds the pipe can be further adjusted according to the tensioning force of the drawstring to avoid tripping of the pipe, and the multi-dimensional pipe cutter can be further adjusted according to the pipe cutting requirements.
Description
Technical field
The present invention relates to a kind of pipe cutter, especially a kind of many size pipes for being adapted to different size pipe requirement
Cutter.
Background technology
Especially fixed length specification when pipe is sold, but the environment that pipe is installed is more complicated, and length is not yet
It is to need to be adjusted tube length in the multiple proportion of tube length specification, therefore pipe installation process, that is, carries out
Cutting, has then invented cutting tool for pipe.
Cutting tool for pipe is commonly used in life, wherein again with rotary-type pipe cutter with more.Pipe exists
Stablize to ensure pipe cutting when cutting, cutting end face is neat, keep axially static between pipe cutter and pipe, pipe
Sub- versus tube cutter can not produce displacement.
But the specification of pipe is relatively more, the thickness of the pipe of all size is different, therefore in order to adapt to different pipes
Specification, needs to adjust the size that pipe cutter clamps pipe, so as to clamp the pipe of different size.Presently mainly by adjusting
The position of pinch roller is changing the size of clamping.
But above-mentioned pipe cutter is to clamp pipe by point-supported mode, cutting when, cutter with pipe
Have between son and relatively rotate, point-supported mode easily causes pipe escape, and especially the larger pipe of caliber, point-supported
Mode cannot guarantee that the axial location of pipe is motionless, cutting track sideslip easily occur, affect the quality of cutting end face.
Then, someone is designed with a kind of mode of axially cladding pipe and is cut, and opens up on pipe cutter and cuts hole, but
It is that the diameter for cutting hole can only adapt to a kind of pipe of specification, therefore in order to adapt to the pipe of different size, cutting on pipe cutter
Hole number is to increase, but the quantity for cutting hole is limited by pipe cutter own vol and work, pipe cutter typically only 2
To 3 cutteves so that one can only at most adapt to pipe cutter the pipe cutting of 3 kinds of specifications, which limits pipe cutter
Adaptability.
The content of the invention
The present invention solves existing pipe and clamps pipe using open point-supported mode, easily causes pipe jump
De-, cutting track sideslip affects the defect of pipe cutting end face quality, there is provided a kind of many size pipes cutteves, pivoted arm and drawstring
Combine for holding pipe tightly, it is to avoid pipe escape, it is ensured that tube axis are not subjected to displacement, it is ensured that the matter of pipe cutting end face
Amount.
This invention also solves existing pipe adopts the blind hole of fixed dimension as pipe cutting hole, pipe is reduced
A kind of adaptability of cutter, there is provided many size pipes cutteves, holds pipe tightly, by drawstring by the combination of pivoted arm and drawstring
It is tensioned length change to adapt to the pipe cutting of different size, improves the adaptability of cutter.
The technical solution adopted for the present invention to solve the technical problems is：A kind of many size pipes cutteves, including lever and
