Description
Technical field
The utility model relates to hardware & tools technical field, especially a kind of serrated knife.
Background technology
Serrated knife is requisite instrument in bench work, is used to the instrument of artificial sawed-off steel plate steel bar, is cut off by the dissection of sawtooth sharp on saw blade.Existing serrated knife saw blade is installed fixing not firm, the butterfly nut that hand Screw is used for fixing saw blade often occurs loosening stubborn not tight situation, and tooth bar can only sawing straight line, and saw cutting angle can not be changed as required, can not meet growing use process requirements.
Utility model content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of serrated knife.
The utility model solves the technical scheme that its technical problem adopts: a kind of serrated knife, comprise saw blade, knife rest and handle of a knife, knife rest one end is provided with handle of a knife, knife rest is provided with saw blade, and saw blade is arranged on knife rest two ends by alignment pin, and alignment pin is provided with screwing wrench, saw blade front end is provided with segment angle scale, be provided with movable groove inside segment angle scale, saw blade front end embeds movable groove, is provided with regulating block outside movable groove.
According to another embodiment of the present utility model, comprise further above saw blade and be provided with fire-bar.
According to another embodiment of the present utility model, comprise further in the middle part of knife rest and be provided with curved handle.
The beneficial effects of the utility model are, structure is simple, and easy to operate, working stability is reliable, strengthen the installation stability of saw blade, avoid loosening, screw unclamp more convenient laborsaving, realize the random adjustment of saw cutting angle, make serrated knife function diversification, effectively improve its operating efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is segment angle scale schematic diagram of the present utility model.
1. saw blades, 2. knife rest, 3. handle of a knife, 4. alignment pin, 5. screwing wrench in figure, 6. segment angle scale, 7. movable groove, 8. regulating block, 9. fire-bar, 10. curved handle.
Detailed description of the invention
As shown in Figure 1, 2, a kind of serrated knife, comprises saw blade 1, knife rest 2 and handle of a knife 3, knife rest 2 one end is provided with handle of a knife 3, knife rest 2 is provided with saw blade 1, and saw blade 1 is arranged on knife rest 2 two ends by alignment pin 4, and alignment pin 4 is provided with screwing wrench 5, saw blade 1 front end is provided with segment angle scale 6, be provided with movable groove 7 inside segment angle scale 6, saw blade 1 front end embeds movable groove 7, is provided with regulating block 8 outside movable groove 7, be provided with fire-bar 9 above saw blade 1, in the middle part of knife rest 2, be provided with curved handle 10.
During use, unclamped by screwing wrench 5 or be wrenched alignment pin 4, make saw blade 1 fixed, the angle of sawing as required, pulling regulating block 8 drives movable groove 7 to rotate on segment angle scale 6, thus regulates the angle of saw blade 1, and the fire-bar 9 above saw blade 1 can heat saw blade 1, avoid saw blade 1 because of temperature too low and brittle, the curved handle 10 in the middle part of knife rest 2 is beneficial in sawing process and exerts a force.
Serrated knife structure after improvement is simple, easy to operate, and working stability is reliable, strengthens the installation stability of saw blade, avoids loosening, and screws to unclamp more convenient laborsaving, realizes the random adjustment of saw cutting angle, makes serrated knife function diversification, effectively improve its operating efficiency.
