Description
Technical field
The utility model relates to cut saw field of tool, and in particular to a kind of durable elastic hand saw that structure is extremely simple.
Background technique
Existing old-fashioned hand saw, the general pin using both ends protrusion hang saw blade, and then adjusting screw is tightened, and exists
Play defect: production process is more, and the production cycle is long, and the semi-finished product in production procedure are more, and occupied fund is more；Hand saw failure risk
High: component part is various, any one part failure will cause entire hand saw to fail.
In addition the most crucial function of hand saw, first is that guarantee saw blade just, it is not crooked in sawing process；Second is that guaranteeing sawing
Saw blade is in the state tightened in journey.About above-mentioned 2 most crucial functions of above-mentioned hand saw, existing old-fashioned hand saw cannot
Realization is completely secured: the every head end of its saw blade only has single side to recline, when practical set saw blade not necessarily just, fitting, the process of sawing
In it can also happen that displacement, skew, sawing face quality decline；Since saw blade can generate heat elongated, existing old-fashioned hand in sawing process
The original tensioned state of saw blade will relax in dragsaw, so that sawing face skew occur, saw blade is also easy to be broken because of relaxation, most
Crucially user is difficult to realize this problem without taking appropriate measures.
Utility model content
In conclusion in order to overcome the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide one kind
The extremely simple durable elastic hand saw of structure.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of durable saw bow that structure is extremely simple, including
Elastic saw bow and saw blade；The rear end of the saw bow is respectively equipped with narrow slit equipped with handle, front end and at the position of handle；Institute
The both ends for stating saw blade are separately fixed in the narrow slit, and its end two sides be close to the inner wall of the corresponding narrow slit to prevent
Only the saw blade be displaced in sawing process or skew.
The beneficial effects of the utility model are: in sawing process saw blade will not be displaced, skew, and even if sawing
Saw blade fever is elongated in the process, also can guarantee that saw blade is continuously in tensioned state, its reliability is made to reach maximization, shape streamline
Graceful, pleasing, sawing is handy, and saw bow, saw blade are more times all durable, and sawing face quality greatly improves.The utility model
Not only reliable in quality, technologically advanced, and the economic investment benefit generated is more significant: and accessory is few, and purchase description of materials is few,
Production link is few, and labour cost is few, and production management work is few, and semi-finished product are few in production procedure, need equipment few, occupied ground
Few, infusion of financial resources is few, and risk is small, and income is quick and abundant.
Based on the above technical solution, the utility model can also do following improvement:
Further, the end two sides of the saw blade are respectively equipped with protrusion, correspond on two lateral walls of the narrow slit described convex
The notch to match with the protrusion is equipped at the position risen；The protrusion is stuck in the corresponding notch to keep the saw
The saw blade and elastic saw bow meeting synchronization telescope after piece expands with heat and contract with cold in sawing process in tensioned state, and the saw blade,
And then prevent the protrusion from detaching the notch.
Beneficial effect using above-mentioned further scheme is: saw blade fever is elongated during sawing, and elastic saw bow can be same
Step elongation tenses saw blade, to guarantee that saw blade is continuously in tensioned state.
Further, the width of the narrow slit and the thickness of the saw blade match.
Detailed description of the invention
Fig. 1 is the three-dimensional figure of the utility model；
Fig. 2 is the A enlarged drawing of Fig. 1；
Fig. 3 is the main view of elastic saw bow；
Fig. 4 is the main view of saw blade.
In attached drawing, parts list represented by the reference numerals are as follows:
1, elastic saw bow, 2, saw blade, 3, handle, 4, narrow slit, 5, protrusion, 6, notch.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As illustrated in fig. 1 and 2, the extremely simple durable saw bow of a kind of structure, including 1 He of elastic saw bow using elastic material production
Saw blade 2.The rear end of the elasticity saw bow 1 is respectively equipped with narrow slit 4 equipped with handle 3, front end and at the position of handle.It is described
The width of narrow slit 4 and the thickness of the saw blade 2 match.The both ends of the saw blade 2 are separately fixed in the narrow slit 4, and
It is close to the inner wall of the corresponding narrow slit 4 to prevent the saw blade 2 to be displaced in sawing process or askew in its end two sides
Tiltedly.
The end two sides of the saw blade 2 are respectively equipped with protrusion 5, correspond to described raised 5 on two lateral walls of the narrow slit 4
The notch 6 to match with described raised 5 is equipped at position.Described raised 5 are stuck in the corresponding notch 6 to keep the saw
Piece 2 be in tensioned state, and the saw blade 2 expand with heat and contract with cold in sawing process after the saw blade 2 with elasticity saw bow 1 can synchronize stretch
Contracting, and then prevent described raised 5 to detach the notch 6.
As shown in Figures 3 and 4, when before elastic saw bow 1 and saw blade 2 are unassembled, the notch 6 of two positions on elastic saw bow 1
The distance between be X, the distance between the protrusion 5 at 2 both ends of saw blade is y, and X is suitably greater than Y.Elastic saw bow 1 and saw blade 2
When assembly, the one of saw blade 2 first is hung up in the narrow slit 4 of the front end (the elastic one end of saw bow 1 far from handle 3) of elastic saw bow 1
End, and guarantee that the protrusion 5 for the end that saw blade 2 is hung up is stuck in the notch 6 in corresponding 4 outside of narrow slit, then the front end of saw bow 1 is supported
On reliable fixture, proficiency handle 3 suitable dynamics opposing compression elasticity saw bow 1, the above-mentioned distance of elastic saw bow 1
X compresses the rear end for 2 other end of saw blade being hung up after the same method again elastic saw bow 1 after certain length.It unclamps and squeezes
After power, elastic force tensioned saw blade 2 that saw bow 1 passes through itself.
The hand saw is after above-mentioned assembly: on the one hand, the position that 2 both ends of saw blade are fixed on saw bow 1, which is equipped with, is suitble to saw blade
The narrow slit 4 of thickness, the end side Liang Ge of saw blade 2 can more closely recline 4 inner wall of narrow slit, and when practical set guarantees saw blade 2
Be entirely capable of just, fitting narrow slit 4, in sawing process saw blade 2 will not be displaced, skew；
Still further aspect, saw blade 2 are tightened, and the method for use is the elasticity using the saw bow 1 itself of elastic material production
Tension realizes, even if saw blade 2 generates heat elongated during sawing, saw bow 1 can synchronize elongation and tense saw blade, to guarantee saw blade
2 are continuously in tensioned state.
In conclusion the hand saw is able to achieve above-mentioned two most crucial function, its reliability is made to reach maximization, shape
Streamline is graceful, pleasing, and sawing is handy, and saw bow, saw blade are more times all durable, and sawing face quality greatly improves.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
