Abstract
The invention discloses a steel saw which can rapidly adjust the space between a saw bow and a saw blade. Most of existing steel saws cannot adjust spaces between saw bows and saw blades, only a small part of steel saws can adjust the spaces between the saw bows and the saw blades, but adjustment is troublesome, the whole steel saw needs to be disassembled, and the adjustment can be achieved only between two specific positions. The steel saw comprises the saw blade, the saw bow, a saw bow tightening device, a handle and an installation head, wherein the saw bow is divided into a front saw bow and a back saw bow, the back saw bow is installed on the handle and can be connected in a rotating mode and is located, and the front saw bow and the back saw bow can be shifted between two positions. Therefore, the design enables the adjustment between the saw bow and the saw blade to be rapid and convenient, the steel saw can be adjusted without the need of disassembling of the steel saw and can be adjusted between multiple positions, and the range of application of the steel saw is widened.
Description
Technical field
The present invention relates to a kind of cutting tool, is the hacksaw of a kind of adjustable segment saw tangent space specifically.
Background technology
Existing hacksaw, a kind of is that cutting room cannot be adjusted, namely the distance between saw bow and the saw blade is changeless, such as Chinese utility model patent ZL03225125.4 " hacksaw of rapid-assembling/disassembling saw blade " and Chinese utility model patent ZL200620088201.2 " multifunctional assembled hacksaw ".This kind hacksaw is after installing saw blade, distance between saw blade and the saw bow is to immobilize, and can cut the workpiece of much (or how thick) and can carry out cutting work in great working space and the distance between saw blade and the saw bow will determine this hacksaw.
Another kind is that cutting room is adjustable, and namely the distance between saw bow and the saw blade is adjustable, such as Chinese utility model patent ZL01203517.3 " Steel saw frame " and Chinese utility model patent ZL200820086922.9 " direction-changeable saw saw ".
The first hacksaw can only carry out cutting operation in a kind of fixing space, cannot adjust the distance of saw blade and saw bow; Although the second hacksaw can be regulated the distance between saw bow and the saw blade, there is following problem:

The specific embodiment
The present invention will be further described by specific embodiment below in conjunction with Figure of description.
As shown in Figure 1 and Figure 2, this hacksaw comprises handle 1, with saw blade 2, saw blade tensioning device 3 (being provided with mount pin 31 on it), mounting head 4 (being provided with mount pin 41 on it) and saw bow 5 compositions of installing hole 21/22, wherein:
" U " shape keeper 7 is respectively arranged with alignment pin 71/72 on it, fixed cover 73 is provided with the fixing hole 74/75 that is complementary with alignment pin on it.In order to prevent that fixed cover 74/75 from coming off from alignment pin 71/72, fixed cover 74/75 can be made with soft plastic (such as rubber, modified PVC etc.).
Front saw bow, rear saw bow, alignment pin, fixed cover can mode as shown in Figure 5 fit together.
Saw blade tensioning device 3 is installed on the handle 1, and how it specifically tightens up saw blade has had a lot of patents to be described, and (such as the ZL200820086922.9 in this patent background technology " direction-changeable saw saw ") is not described in detail in this.
On handle 1, also be provided with mounting groove 19 (seeing accompanying drawing 8), on the rear wall 15 of mounting groove 19 and antetheca 16, be coaxially arranged with respectively scallop 11, profile of tooth counterbore 12 and through hole 14, and step surface 13 forms.In mounting groove 19, also be respectively arranged with the first locating surface 17 and the second locating surface 18, these two locating surfaces 17/18 define the rotational angle of rear saw bow in mounting groove 19, make things convenient for the user to find fast the position of ultimate range and minimum range between saw bow and the saw blade when regulating.When being resisted against the first locating surface 17, rear saw bow by regulating the angle between front saw bow and the rear saw bow, can make between saw bow and the saw blade to have ultimate range; When being resisted against the second locating surface 18, rear saw bow by regulating the angle between front saw bow and the rear saw bow, can make between saw bow and the saw blade to have minimum range.When the diverse location of rear saw bow between the first locating surface 17 and the second locating surface 18 rotates and during the location, can adjust between saw bow and the saw blade to have different distance, thereby can adjust best service range according to the needs of real work.
Rear saw bow, handle and keeper mode as shown in Figure 8 is assembled together.
During use, can be first rear saw bow be inserted the mounting groove of handle, make rear saw bow abut to the first locating surface 17, keeper is penetrated so that step surface 13 and positioning step 63 mutually against, then at the double-screw bolt 62 of the keeper nut 64 of screwing on.Again front saw bow and rear saw bow are docked, so that the first through hole 54 and fifth hole 58 alignment with the second through hole 55 and third through-hole 57 alignment, penetrate " U " shape keeper and are inserted in fixed cover simultaneously.Mounting head is assembled on the front saw bow again, loads onto at last saw blade and by saw blade tensioning device saw blade is strained.The hacksaw that assembles like this has maximum cutting distance as shown in Figure 1 between saw bow and the saw blade.
When needs adjust between saw bow 5 and the saw blade 2 apart from the time, can unscrew first saw blade tensioning device pulls down saw blade, unscrew again 64 and press keeper 6 until rear saw bow 51 can make in 19 li rotations of mounting groove of handle after saw bow abut to the second locating surface 18, fastening nut 64 is positioned at rear saw bow on the handle reliably again.Afterwards " U " shape keeper is pulled down, the angle of saw bow and front saw bow after adjusting is so that the first through hole 54 and fifth hole 58 alignment with the second through hole 55 and fourth hole 56 alignment, again penetrate " U " shape keeper 7 and are inserted in fixed cover 73 simultaneously again.Load onto at last saw blade and by saw blade tensioning device saw blade is strained.The hacksaw that assembles like this has minimum cutting distance as shown in Figure 2 between saw bow and the saw blade.
In like manner by the angle between saw bow after adjusting and the handle, can make to have different cutting distances between saw bow and the saw blade, satisfy not being both user demand.
Just realized very fast and easily the adjusting of distance between saw bow and the saw blade by top several steps.
Above-mentioned specific embodiment is most preferred embodiment of the present invention, and any non-simple transformation through creative work should think to fall into the scope of the claim of this invention.
