Abstract
The utility model discloses a kind of outer camber segmentation saw blade, comprise blade body, described blade body comprises saw handle connecting portion, saw blade back and saw blade sawtooth, described saw blade sawtooth comprises the sawtooth portion of at least two sections of outer convexs, by adopting the sawtooth of the outer convex of multistage can effectively improve the cutting force of saw blade, in actual use, after tested, adopt saw blade of the present utility model can improve cutting force more than 20%, effective minimizing personnel's labour intensity, and improve the efficiency of work.
Description
Technical field
The utility model relates to a kind of saw blade, particularly a kind of outer camber segmentation saw blade.
Background technology
At present; for the thick branch of gardening, trunk pruning or timber, often cut apart and can use combination saw; combination saw is normally comprised of saw handle and saw blade; on saw handle, there is the fixedly device of saw blade; and on saw blade, offer with this and install corresponding connecting portion, change saw blade very convenient, but mostly such saw blade is straight type sawtooth or continuous interior camber sawtooth at present; when cutting continuously, its cutting force can be not enough to some extent, increases operator's labour intensity.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the outer camber segmentation saw blade that a kind of cutting force is large.
The utility model solves the technical scheme that its technical problem adopts:
An outer camber segmentation saw blade, comprises blade body, and described blade body comprises saw handle connecting portion, saw blade back and saw blade sawtooth, and described saw blade sawtooth comprises that the sawtooth portion of at least two sections of outer convexs forms.
Described saw blade sawtooth is comprised of the sawtooth portion of five sections of outer convexs.
Described saw blade back is an interior curved bow-shaped structural.
The junction of adjacent sawtooth portion is provided with escape.
The beneficial effects of the utility model are: a kind of outer camber segmentation saw blade, comprise blade body, described blade body comprises saw handle connecting portion, saw blade back and saw blade sawtooth, described saw blade sawtooth comprises the sawtooth portion of at least two sections of outer convexs, by adopting the sawtooth of the outer convex of multistage can effectively improve the cutting force of saw blade, minimizing personnel's labour intensity, and improve the efficiency of work.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of first specific embodiment of the utility model;
Fig. 2 is the structural representation of second specific embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 1 is the structural representation of first specific embodiment of the utility model, as shown in the figure, a kind of outer camber segmentation saw blade, comprise blade body, described blade body comprises saw handle connecting portion 1, saw blade back 2 and saw blade sawtooth, described saw blade sawtooth comprises the sawtooth portion 31 of at least two sections of outer convexs, in the present embodiment, described saw blade sawtooth is comprised of the sawtooth portion 31 of five sections of outer convexs, by adopting the sawtooth of the outer convex of multistage to make saw blade in carrying out the process of dragsaw cutting, its resistance or dragsaw power are the value of a fluctuation, dragsaw cutting formation one has the variable force process of certain frequency, effectively improve the cutting force of saw blade, more easily efficient of dragsaw cutting, in actual use, after tested, adopt saw blade of the present utility model can improve cutting force more than 20%, effective minimizing personnel's labour intensity, and improve the efficiency of work.
As shown in the figure, described saw blade back 2 is an interior curved bow-shaped structural, and the saw blade of this structure is higher for the cylindrical cutting efficiency of trunk or timber that waits, and applicable and gardens are more used.
With reference to Fig. 2, Fig. 2 is the structural representation of second specific embodiment of the utility model, as shown in the figure, in the present embodiment, the junction of adjacent sawtooth portion 31 is provided with escape 32, and this escape 32 can, for holding wood chip and exiting wood chip in the saw blade course of work, further improve the speed of cutting, reduce the resistance of wood chip, improve the speed of sawmilling material or trunk.
Above better enforcement of the present utility model is illustrated; certainly; the utility model can also adopt form different from the embodiment described above; as sawtooth portion 31 can be set to two sections or multistage; therefore the conversion being equal to that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or accordingly change, all should belong in protection domain of the present utility model.
