[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0026] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] refer to Figure 1-2 The annular groove blade shown in the figure comprises: a blade body, the blade body comprises a blade body 1 and two blade heads 2 respectively arranged at both ends of the blade body 1; the side of the two blade heads 2 away from each other is a blade portion 3. In this way, the blade body 1 is provided with blade heads 2 at both ends, and a blade portion 3 is arranged on each blade head 2. When one blade portion is damaged, the blade body is turned 180 degrees to place the other blade portion 3 in a processing position for processing. Therefore, the present application adopts a double blade head design to maximize the use of the blade body 1 and make the blade more cost-effective.

[0029] refer to Figure 1 and 3 As shown, the side of the cutter head 2 adjacent to the blade 3 extends toward the blade body 1 to form an avoidance groove 4, so as to avoid interference during processing. The shape of the avoidance groove 4 is processed according to the specific use environment.

[0030] refer to Figure 1 and 2 As shown, in order to further improve the adaptability, the side of the cutter head 2 away from the blade 3 is a first bevel 5, and the inclination direction of the first bevel 5 is from the side of the end of the blade body 1 away from the blade 3 to the side close to the blade 3, so that the end of the cutter head 2 away from the blade body 1 becomes smaller and smaller, so as to further improve the ability to avoid workpieces and avoid interference.

[0031] refer to Figure 3 and 4 As shown, the side of the cutter head 2 away from the first bevel 5 is the second bevel 6, and the inclination direction of the second bevel 6 is inwardly inclined from the blade 3 to the end of the blade body 1. The best inclination angle α of the second bevel 6 is 4 to 6 degrees (can be 4, 5, 6, etc.), and the side of the second bevel 6 close to the blade 3 is provided with a third bevel 7, and the inclination direction of the third bevel 7 is inwardly inclined from the suspension end of the cutter head 2 along the extension direction of the blade 3, and the best inclination angle β of the third bevel 7 is 0.5 to 1.5 degrees (can be 0.5, 1, 1.5, etc.). By arranging the second bevel 6 and the third bevel 7 at the front end of the blade 3, the blade 3 is sharper, the cutting is easier, and the service life of the blade can be effectively improved.

[0032] refer to Figure 1 and 3 As shown, in order to facilitate the installation of the blade, positioning grooves 8 are provided on both sides of the blade body 1, and the blade is positioned through the positioning grooves 8 (matched with a suitable pressure plate during installation), thereby improving installation efficiency and stability during use.

[0033] Further optimization is to refer to Figure 1 and 3 As shown, both sides of the positioning groove 8 are inclined surfaces, thus further improving the accuracy of blade installation.

[0034] Further optimization is that the cutter body can be made of materials such as high-speed steel, cemented carbide and cubic boron nitride.

[0035] The working principle of the utility model is as follows: a blade head 2 is arranged at both ends of a blade body 1, and a cutting edge 3 is arranged on each blade head 2. When one cutting edge is damaged, the blade is turned 180 degrees so that the other cutting edge 3 is in a processing position for processing. Therefore, the present application adopts a double blade head design to maximize the use of the blade body 1 and make the blade more cost-effective.

[0036] By arranging the second bevel 6 and the third bevel 7 at the front end of the blade 3, the blade 3 is made sharper, cutting is made easier, and the service life of the blade is effectively prolonged.

[0037] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
