In addition, the automobile air conditioner can reduce the damage of articles and personnel in the automobile caused by ultraviolet irradiation, and reduces the temperature in the automobile and the use of the automobile air conditioner through physical reflection, thereby reducing the oil consumption and saving part of expenses.
In the prior art, when the automobile film is pasted, a special film pasting cutting tool is not provided, and the film is cut by adopting an art knife. The structure of the blade 1 of the prior art knife is shown in fig. 1 and is a parallelogram; the blade 1 is provided with a blade edge 1-1, a breaking line 1-2 and a round hole 1-3; the cutting edge 1-1 is arranged at the edge of one long parallel edge of the blade 1; the broken lines 1-2 are arranged in parallel to the short parallel edges of the blade 1, and the distance between every two adjacent broken lines 1-2 is equal; the round holes 1-3 are arranged at the bottom and used for fixing the art designing knife. Although the utility knife has low cost and convenient operation, the utility knife has the following defects. Firstly, in the automobile film pasting process, water and mounting liquid, namely the liquid which is contacted with the art knife blade, are needed to be used frequently, 60 steel is easy to rust and cannot meet the use requirement, and the SK2 steel has good rust resistance, but the performances of wear resistance, corrosion resistance, hardness and the like are still to be improved. Secondly, because the blade has certain length, when the blade distance that uses is longer, because top, middle part and bottom bearing capacity are different, the blade easily produces the bending, if exert oneself great, still has the fracture risk. And thirdly, the width of the cutting edge is narrow, which is generally only 10 percent of the width of the blade 1, and the sharpness is not enough.
SUMMERY OF THE UTILITY MODEL
In view of this, in order to solve the technical problem in the prior art, the utility model provides a compound blade.
The utility model provides a technical scheme as follows that above-mentioned technical problem took.

the blade is provided with a cutting edge, a breaking line and a round hole;
the blade edge is arranged at the edge of one long parallel edge of the blade, and the width of the blade edge is 20-25% of the width of the blade;
the broken lines are arranged in parallel with the short parallel edges of the blade, the distance between every two adjacent broken lines is sequentially increased from top to bottom, the distance is increased from 6-7mm, and each time the distance is increased by 0.5 mm;
the included angle between the broken line and the knife edge is 30-60 degrees;
the circular hole is arranged at the bottom of the blade and used for fixing the composite blade;
the ceramic coating is sprayed on the surface of the blade outside the blade edge, and the thickness of the ceramic coating is 0.02-0.03 mm.
Further, the material of the blade is SK2Alloys or SK2Cr4And (3) alloying.
Further, the ceramic coating is made of alumina, zirconia or chromium oxide.
Furthermore, a notch is formed in the upper right corner of the blade.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a compound blade on the one hand is from last to gradually increasing up down through adjustment thickness, realizes hardness from last to gradually increasing up down, and on the other hand guarantees the blade when using through the interval crescent of adjusting two adjacent broken lines, no matter the length of use length, can both the steady operation, and especially use length is longer, and the difficult production in blade middle part and lower part is buckled, the fracture.
The utility model discloses a composite blade's surface is ceramic coating, has increased corrosion resistance, hardness, wearability, the oxidation resistance etc. of blade.
The utility model discloses a compound blade adopts the design of wide sword mouth, the sharpness of the blade of increase.
