The utility model is in order to solve the above-mentioned defect and deficiency that exist in prior art, provide and a kind of there are the two saw-blade structures preventing chip jam saw blade, effectively can prevent the space between the two saw blade of the chip jam that produces in working angles, cause motor damage or personnel's injury.
For solving the problems of the technologies described above, the utility model provides a kind of and has the two saw-blade structures preventing chip jam function, comprise and rotating and the contrary outer-side saw blade of direction of rotation and inner side saw blade around same axis, described outer-side saw blade is made up of outer-side saw blade body, outer-side saw blade cutter unit, and described inner side saw blade is made up of inner side blade body, inner side saw blade cutter unit; The main cut surface of outer-side saw blade that described outer-side saw blade cutter unit has outer or line, described inner side saw blade cutter unit has the main cut surface of inner side saw blade or the line of outer; Described outer-side saw blade cutter unit has the outer-side saw blade inclined-plane be connected with the main cut surface of described outer-side saw blade or line, described outer-side saw blade inclined-plane and corner plane adopt direct wedge angle to be connected, described corner plane and described axis being parallel, described inner side saw blade cutter unit has the saw blade inclined-plane, inner side be connected with the main cut surface of described inner side saw blade or line, saw blade inclined-plane, described inner side adopts direct wedge angle to be connected with secondary cut surface, and described time cut surface is parallel with described corner plane.
Preferably, the angle theta of described outer-side saw blade inclined-plane and described corner plane
1for acute angle, the angle theta of saw blade inclined-plane, described inner side and described cut surface
2for acute angle.
Preferably, the angle theta of described outer-side saw blade inclined-plane and described corner plane
1for obtuse angle, the angle theta of saw blade inclined-plane, described inner side and described cut surface
2for obtuse angle.
Preferably, described angle theta
1and θ
2equal.
Preferably, described angle theta
1and θ
2it is 60 degree.
Preferably, described angle theta
1and θ
2it is 120 degree.
The Advantageous Effects that the utility model reaches:
Of the present utility model pair of saw blade, owing to having outer-side saw blade inclined-plane and saw blade inclined-plane, inner side, prevent in cutting process, chip falls in the space between two blade bodies, even if there is part chip to enter space, due to the existence of secondary cut surface, chip can be cut into further dust and be thrown out of, fundamentally solve cutting chip and enter space between two blade bodies and the problem that causes two saw blade stuck, effectively improve the security of product and extend service life of product.

Another specific embodiment structural representation of Fig. 2 the utility model.
Detailed description of the invention
In order to the technique effect that auditor can better understand technical characteristic of the present utility model, technology contents and reach, now accompanying drawing of the present utility model is described in detail in conjunction with the embodiments.But shown accompanying drawing, just in order to better illustrate the technical solution of the utility model; be not actual proportions of the present utility model and best configuration; so, ask auditor not with regard to ratio and the configuration of accompanying drawing, limit claims of the present utility model.
Below in conjunction with drawings and Examples, the utility model patent is further illustrated.
As shown in Figure 1-2, the utility model provides a kind of and has the two saw-blade structures preventing chip jam function, comprise and rotating and the contrary outer-side saw blade 1 of direction of rotation and inner side saw blade 2 around same axis, described outer-side saw blade 1 is made up of outer-side saw blade body 11, outer-side saw blade cutter unit 12, and described inner side saw blade 2 is made up of inner side blade body 21, inner side saw blade cutter unit 22; The main cut surface of outer-side saw blade that described outer-side saw blade cutter unit 12 has outer or line 121, described inner side saw blade cutter unit 22 has the main cut surface of inner side saw blade or the line 221 of outer; Described outer-side saw blade cutter unit 12 has the outer-side saw blade inclined-plane 122 be connected with the main cut surface of described outer-side saw blade or line 121, described outer-side saw blade inclined-plane 122 and corner plane 123 adopt direct wedge angle to be connected, described corner plane 123 and described axis being parallel, described inner side saw blade cutter unit 22 has the saw blade inclined-plane, inner side 222 be connected with the main cut surface of described inner side saw blade or line 221, saw blade inclined-plane, described inner side 222 adopts direct wedge angle to be connected with secondary cut surface 223, and described time cut surface 223 is parallel with corner plane 123.
When using utility model works, outer-side saw blade 1 and inner side saw blade 2 rotate by contrary direction simultaneously, outer-side saw blade cutter unit 12 and inner side saw blade cutter unit 22 directly cut cut object, the fragment cut down falls into the space between outer-side saw blade inclined-plane 122 and saw blade inclined-plane, inner side 222, due to the existence on outer-side saw blade inclined-plane 122 and saw blade inclined-plane, inner side 222, chip is blocked and rests on inclined-plane, then is thrown out of by the effect of centrifugal force.Even if having part chip through the space outer-side saw blade inclined-plane 122 and saw blade inclined-plane, inner side 222, when through angle theta
