Abstract

The utility model relates to a universal steel saw which is provided with a front and a back wide side pulling and supporting columns which are same, the lower side of the wide side is provided with radial fine threads. Meanwhile, the utility model is provided with a front and a backdirection finders which are same and are provided with the same radial fine threads. After the assembly, the two fine thread surfaces are in contact with each other; when in the loosen time, the pull support columns can be rotated to adjust the direction optionally; when in the tensioning time, the direction of the cut of the universal steel saw can be locked. The back pulling and supporting column and the tensioning element are separated, so that no matter the steel saw blade is tensioned in any way, the lateral stability of the back pulling and supporting column is not influenced to thoroughly eliminate the difficult problem that the direction of the cut of the saw is damaged when the saw blade is tensioned. Meanwhile, a novel saw frame is adopted, so that the strength intensity of the whole saw is higher, and the stability of the whole saw is better.

Description

The omnipotent hacksaw of novel universal

Affiliated technical field

The utility model relates to a kind of cutting tool, especially the omnipotent hacksaw of novel universal.

Background technology

There is a major defect in known universal omnipotent hacksaw at present, and Here it is, and its post-tensioning dagger and lashing post are one, after rotation post-tensioning dagger mixes up the saw kerf direction, during the female tension of rotation ingot sieve saw blade, the post-tensioning dagger destroys the saw kerf direction that has mixed up easily along with commentaries on classics.Though designed band melon pad, and at the female Nei Jia grease of ingot sieve, reducing horizontal commentaries on classics power, but still can not thoroughly solve the problem of destroying the saw kerf direction.Therefore, when the female tension of rotation ingot sieve saw blade, have to buttress the post-tensioning dagger relatively not too convenient with finger.Existing universal omnipotent hacksaw of while, the saw frame form is outmoded, and its saw intensity and steadiness are all relatively poor.

Summary of the invention

In order to overcome existing universal omnipotent hacksaw, destroy the difficult problem of saw kerf direction during the tension saw blade, the deficiency outmoded with the saw frame form, the utility model provides a kind of novel universal omnipotent hacksaw, this saw destroys the difficult problem of saw kerf direction when not only thoroughly having eliminated the tension saw blade, and saw intensity is higher, and steadiness is better, uses more convenient.

The technical scheme that its technical problem that solves the utility model adopts is: designed former and later two identical broadside stay bolt posts, radial microgroove has been arranged below its broadside.Why is the limit wide? exactly in order to satisfy needed area.Two identical finders before and after having designed simultaneously, its shape is square, there is the hole, garden the centre, and same radial microgroove is also arranged above it.Microgroove wide and deeply all be 0.3 millimeter, and much bigger at interval.After assembling, below the stay bolt post broadside with contact above the finder, card mutually, if card mutually, just can't tuning.In fact this is artificial two coarse especially planes of manufacturing.Since be the plane, when loosening, the rotatable random tuning of stay bolt post.Though because it is the plane, coarse especially again, its frictional force of tension back is enough to lock the saw kerf direction.

The trend of this new construction is: can separate post-tensioning dagger and tension part (arm of living).Make and no matter adopt which kind of mode to strain saw blade, do not influence the lateral stability of post-tensioning dagger, thereby thoroughly eliminated a difficult problem of destroying the saw kerf direction.During the tension saw blade, neither need be with the melon pad, also need not add grease, more need not point and hold up, very convenient.

Saw frame selects for use canal shape steel pipe to make the saw beam, and forearm and handle are done with die casting aluminium, and adopts the lever mode to strain saw blade.

The beneficial effects of the utility model are, thoroughly eliminated the difficult problem that existing universal omnipotent hacksaw destroys the saw kerf direction, and saw intensity are higher, and steadiness is better, uses more convenient.Also can deposit saw blade in the saw beam.

Description of drawings

Fig. 1 is the omnipotent hacksaw full figure of novel universal.

Fig. 2 is the finder plane.

Fig. 3 is arm part cutaway view of living.

Among the figure 1, preceding finder, 2, preceding stay bolt post, 3, forearm, 4, saw blade, 5, the saw beam, 6, the post-tensioning dagger, 7, handle, 8, the back finder, 9, the arm of living, 10, two extension bars, 11, jump ring, 12, tie rod.

The specific embodiment

In Fig. 1, below the broadside of preceding stay bolt post (2), and contact above the preceding finder (1), card mutually.Below the broadside of post-tensioning dagger (6), with the back finder (8) above contact, mutually the card.Finder is square not rotating.At this moment decontrol tie rod (12), rotatable arbitrary stay bolt post, 360 ° suitable, return the random tuning of hour hands.After mixing up the saw kerf direction.Depress tie rod (12), promptly strain saw blade (4), and locking saw kerf direction.Can grasp and cut the beginning cutting operation this moment.

Because post-tensioning dagger (6) and work arm (9) no one, no matter use the lever mode, still the rib-loop mode is braked arm alive (9) tension saw blade (4), and the lateral stability of post-tensioning dagger (6) is not all had influence, thereby has thoroughly eliminated a difficult problem of destroying the saw kerf direction.

Claims

The omnipotent hacksaw of a kind of novel universal, it is characterized in that: this saw has designed former and later two identical broadside stay bolt posts, radial microgroove is arranged below its broadside, two identical finders before and after having designed simultaneously, finder top also has same radial microgroove, assembling latter two microgroove face contacts, do not block mutually, the rotatable random tuning of stay bolt post when loosening, strain back lockable saw kerf direction, and post-tensioning dagger and tension part are separated, adopt the sort of mode to strain saw blade no matter make, do not influence the lateral stability of post-tensioning dagger, thereby thoroughly solved a difficult problem of destroying the saw kerf direction when straining saw blade.
