However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-2 As shown, this utility model provides a right-angle scraper for aviation sealant, including a handle part 1 and a blade head 2. The blade head 2 is connected to one end of the handle part 1, and a flat blade 3 is provided at the end of the blade head 2 away from the handle part 1. A vertical blade 4 is provided on the surface of the blade head 2, and one end of the vertical blade 4 is connected to the surface of the flat blade 3. The vertical thickness of the vertical blade 4 is greater than the vertical thickness of the blade head 2, and an auxiliary groove 5 is provided on the surface of the handle part 1.

[0024] As a further step, the handle portion 1 includes a tail end portion 11 and a connecting portion 12 connected to the tail end portion 11. One end of the connecting portion 12 is connected to the blade head 2. The thickness of the connecting portion 12 is equal to the thickness of the blade head 2, and an auxiliary groove 5 is provided on the connecting portion 12.

[0025] As a further step, the auxiliary groove 5 includes a first arc-shaped groove 51 provided on one side of the connecting portion 12 and a second arc-shaped groove 52 provided on the other side of the connecting portion 12, with the first arc-shaped groove 51 and the second arc-shaped groove 52 being provided correspondingly.

[0026] The design of the first arc groove 51 and the second arc groove 52 makes the handle part 1 ergonomic. The auxiliary groove 5 helps the user to grip with their thumb and forefinger, which makes it easier to push the handle part 1 and the blade head 2 forward. This not only saves effort during operation but also enables precise control.

[0027] Furthermore, the width of the tail end 11 gradually increases outward from the connecting part 12, and the longitudinal section of the tail end 11 is trapezoidal. The surfaces of the tail end 11 and the connecting part 12 are respectively provided with rounded corners. With the help of the rounded corner design, this utility model can help improve the user's comfort when using it. It not only saves effort during operation, but also prevents scratches and has a certain degree of safety.

[0028] Furthermore, the thickness of the tail end 11 is greater than that of the tail end 12, and an inclined plane is provided at the connection between the tail end 11 and the connecting part 12. This design not only enhances the strength of the tail end 11, but also facilitates user operation and helps the handle part 1 to push forward with force, resulting in better glue removal effect of the flat blade 3.

At the same time, this material has a long service life, effectively reducing the cost of use.

[0030] As a further step, the handle 1, the blade head 2, the flat blade 3, and the vertical blade 4 are integrally formed, and the integral forming process ensures the stability and reliability of the overall structure of this utility model.

[0031] Furthermore, the flat blade 3 and the vertical blade 4 each have a blade angle of 30°. It is worth noting that the flat blade 3 and the vertical blade 4 can have a relatively large reserved length during the forming process, which helps with the later sharpening operation and improves the service life of this utility model.

[0032] The working principle of this utility model is as follows: The right-angle scraper of this utility model is integrally molded from polyetheretherketone material, which effectively ensures the hardness and wear resistance of the right-angle scraper and ensures that it will not cause any damage to the substrate during the glue removal process, making it highly practical. Furthermore, the flat blade 3 and the vertical blade 4 are each at a 30° blade angle, and the length of the flat blade 3 and the vertical blade 4 can be reserved during molding, which helps with the later sharpening operation and improves the service life of the right-angle scraper. At the same time, the handle part 1, with the design of the tail end 11, the connecting part 12 and the auxiliary groove 5, makes the right-angle scraper more ergonomic, which makes it easier to push the blade head 2 forward. During operation, it not only saves effort but also enables precise control and has a better glue removal effect.
