Description

Flexible saw

Technical field

The utility model relates to a kind of cutting tool, particularly a kind of Flexible saw.

Background technology

Cutting tool of the prior art is rigid structure, requirement to the operating space is comparatively harsh, for example be positioned at pipeline or other plastic device that need cut at corner and other narrow place, space, the cutting tool of this rigid structure just is difficult to operation, even can't use.

Summary of the invention

The purpose of this utility model is to overcome weak point of the prior art, and a kind of flexible operation, Flexible saw that space adaptability is strong are provided.

The purpose of this utility model realizes through following scheme.

Flexible saw comprises handle, and its structural feature is, also includes a kind of flexible strip, and the both ends of flexible strip are connected with handle.

The utility model utilizes the characteristic that can bend arbitrarily of flexible strip, satisfies the specific (special) requirements of the operating space that the rigid structure cutting tool can't satisfy, and it can be applicable to the cutting that is positioned at objects such as corner, underground, ceiling such as pipeline.

During use, as long as make the flexible strip ring enclose in body surface and vertical with body surface, and hand-held handle can be finished the cutting of any plane curve doing motion all around perpendicular to the plane of body surface.

If the volume of handle is excessive, then will shake hands and the flexible strip flexible connection, like this, if when running into the situation as the pipeline of cutting corner, just can earlier flexible strip be passed the slit, connect handle again, thereby no matter how little the slit have, all can realize operation, thereby and can not occur to pass slit generation trouble because of the volume of handle is excessive.

Flexible strip or be single metal wire, or the rope that becomes twisted shape to tangle for the complex root wire.

Single metal wire is applicable to the material that cutting is comparatively soft, as rubber; The rope that the complex root wire becomes twisted shape to tangle is applicable to comparatively hard material, as timber, plastics, lucite or the like.

The complex root wire is made the rope that twisted shape tangles, will form the twill zigzag automatically, thereby make flexible strip comparatively sharp, laborsaving during operation.

The utility model further is wire or is steel wire, or is iron wire.

Steel or iron hardness height, not yielding.Steel wire and iron wire have very strong cutting performance under external force, use also saferly, and can twist arbitrarily at three-dimensional, and this is the existing saw tool effect that is beyond one's reach.

In order to improve work efficiency of the present utility model, that strengthens flexible strip hugs the stranding attriting performance, can make wire be continuous fluctuating shape along its length direction, is specifically as follows zigzag.

The utility model also includes a kind of ring set, is sleeved in the ring set simultaneously with flexible rule body after the inflection of flexible strip end and compresses ring set and realize this end being fastenedly connected of bar body therewith, shakes hands to be formed ring after the inflection of flexible strip both ends.

Ring set is fixed into ring with the flexible strip both ends.Ring can be directly as handle.Ring set can be a locking device, also can be movable locking device.

Be set with a kind of flexible shroud on the flexible strip in the ring.

Flexible shroud or be plastic bushing, or be gum sleeve, or be the cloth sleeve pipe.

Flexible shroud makes handle have more holding property, and operator's hand is not injured.

Flexible shroud can become tubulose, also can slabbing and be fixed into tubulose through box and pin.

A kind of handle is connected with ring.

Handle or be "T"-shaped, or be that a kind of drum is circular, or be a kind of " " shape, or be a kind of

Shape, or be a kind of " △ " shape.Handle can have locking device simultaneously.Adopt which kind of shape handle to decide on operator's hobby.

Handle is connected with the flexible strip two ends is dismantled and assembled by the releasable connection device.

The releasable connection device can be to have the through hole that the flexible strip both ends can be inserted on handle, and then fastening with trip bolt or spring attachment.

Handle is a kind of handle, the releasable connection device comprises a kind of holding screw, the horizontal cross-under of this holding screw is in the cross-drilled hole of the prominent head of handle, the cross-under of flexible strip end is in the horizontal open-work of this cross-drilled hole and holding screw end, rotate holding screw, make the flexible strip end compacted, thereby reach the fastening purpose of handle and flexible strip end because of dislocation in cross-drilled hole and horizontal open-work.

The utility model is the following advantage of tool compared to prior art: flexible operation, space adaptability are strong, safe in utilization, and cutting is convenient, and laborsaving, it is also easy collect, does not take up space, and are not only applicable to the house, also are applicable to field operation.
