Abstract
A kind of reciprocating saw of adjustable sawtooth density, including saw body and saw blade, saw blade includes the first tooth plate, second tooth plate and several sawtooth, one end of sawtooth is located between the first tooth plate and the second tooth plate, first tooth plate and the second tooth plate fix sawtooth by fishbolt, the one end of first tooth plate and the second tooth plate far from saw body is equipped with coiler, first tooth plate is set close to one end of saw body there are one limited block, second tooth plate is set close to one end of saw there are one groove, limited block is absorbed in groove after first tooth plate and the second tooth plate fix sawtooth, sawtooth is linked together by an elastic string, one end of elastic string is in coiler, first sawtooth of the elastic string other end is equipped with and the matched limit hole of limited block.The present invention its elastic string when idle is inconjunction with sawtooth and collapses in coiler, sawtooth can be effectively prevent to accidentally injure other people, and when use can adjust the density of sawtooth as the case may be, very convenient.
Description
Technical field
The invention belongs to field of power tools, and in particular to a kind of reciprocating saw of adjustable sawtooth density.
Background technology
Reciprocating saw be by jagged saw blade when saw blade is reciprocal back and forth cutting material.Reciprocating saw is commonly provided with multiple saws
Item, the distinctive points of these saw blades are that the sawtooth density above them is different, dredge the surface that is efficient, but cutting out of saw cut
Coarse, the efficiency of close saw cut is low but the surfacing that cuts out.Therefore in cutting, operator often selects according to situation
Most suitable saw blade is selected, but so just has to carry these saw blades at any time, it appears is inconvenient.And exposed sawtooth
Other people may be caused to accidentally injure themselves with, it is very dangerous.
Invention content
For deficiency of the prior art, the present invention provides a kind of reciprocating saw that can adjust sawtooth density.
The invention is realized by the following technical scheme, a kind of reciprocating saw of adjustable sawtooth density, including saw body and saw blade,
The saw blade includes the first tooth plate, the second tooth plate and several sawtooth, and one end of the sawtooth is located at the first tooth plate and the second tooth plate
Between, first tooth plate and the second tooth plate fix sawtooth by fishbolt, and first tooth plate and the second tooth plate are remote
One end from saw body is equipped with coiler, and first tooth plate sets that there are one limited block, second tooth plates close to one end of saw body
It being set close to one end of saw there are one groove, limited block is absorbed in groove after first tooth plate and the second tooth plate fix sawtooth,
The sawtooth is linked together by an elastic string, and in coiler, the elastic string is another for one end of the elastic string
First sawtooth of one end is equipped with and the matched limit hole of limited block.
Further, after the tapered shape of the sawtooth and the width of its bottom are bonded with the first tooth plate and the second tooth plate
Thickness is identical.
Further, the both ends of first tooth plate and the second tooth plate are respectively provided with a fishbolt so that the first tooth plate
22 and second tooth plate 23 it is more preferable to the fixed effect of sawtooth 21.
Compared with prior art, the present invention its elastic string when idle is inconjunction with sawtooth gathering in coiler, in this way may be used
Sawtooth to be effectively prevent to accidentally injure other people, when use, pulls out elastic string out of coiler, fishbolt is unclamped, by first sawtooth
On limit hole be fixed on limited block, then by one end of remaining sawtooth be evenly spaced in the first tooth plate and the second tooth plate it
Between, tighten fishbolt；To adjust the density of sawtooth, fishbolt, the retracting of rotation coiler or release bullet are first unclamped
Property rope so that the spacing between adjacent saw-tooth becomes larger or becomes smaller, and then tightens the exchanging density that fishbolt realizes sawtooth again.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the sectional view in A-A directions in Fig. 1.
Fig. 3 is the structure diagram after opposite Fig. 1 sawtooth become close.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.As shown in Figs. 1-3, it is a kind of adjustable
The reciprocating saw of sawtooth density, including saw body 1 and saw blade 2, the saw blade 2 includes the first tooth plate 22, the second tooth plate 23 and several saws
Tooth 21, one end of the sawtooth 21 are located between the first tooth plate 22 and the second tooth plate 23,22 and second tooth plate of the first tooth plate
23 fix sawtooth 21 by fishbolt 5, and described first tooth plate, 22 and second one end of tooth plate 23 far from saw body 1 is equipped with volume
Device 4 is received, the elastic string 3 can be inconjunction with sawtooth 21 and be involved in coiler 4, and first tooth plate 22 is close to one end of saw body 1
If there are one limited block 221, second tooth plate 23 sets that there are one groove 231, first tooth plates 22 close to one end of saw body 1
Limited block 221 is absorbed in groove 231 after fixing sawtooth 21 with the second tooth plate 23, and the sawtooth 21 is connected by an elastic string 3
It is connected together, one end of the elastic string 3 is set in coiler 4 on first sawtooth 21 of 3 other end of elastic string
Have and 221 matched limit hole 211 of limited block.
The 21 tapered shape of sawtooth and the width of its bottom be bonded with the first tooth plate 22 and the second tooth plate 23 after thickness
It spends identical.
In above-mentioned technical proposal, the coiler 4 is equipped with 3 index lines and 1 root pointer, pointer when coiler 4 rotates
And then it rotates, every index line represents the density degree of pointer sawtooth 21 when going to different instruction line positions.
In above-mentioned technical proposal, the both ends of 22 and second tooth plate 23 of the first tooth plate are respectively provided with a fishbolt 5.
The present invention its elastic string when idle is inconjunction with sawtooth and collapses in coiler, sawtooth can be effectively prevent to miss in this way
Hinder other people, when use pulls out elastic string out of coiler, unclamps fishbolt, the limit hole on first sawtooth is fixed to
On limited block, then one end of remaining sawtooth is evenly spaced between the first tooth plate and the second tooth plate, tightens fishbolt i.e.
It can；To adjust the density of sawtooth, fishbolt, the retracting of rotation coiler or release elastic string are first unclamped so that adjacent saw-tooth
Between spacing become larger or become smaller, then tighten the exchanging density that fishbolt realizes sawtooth again.
