Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0013] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0014] Example 1: This embodiment provides a 45-degree tenoning tool, including: The handle 1 is cylindrical in shape. The blade body 2 is connected to the end of the handle 1. The blade body 2 includes two cutting parts, which are arranged in a rotationally symmetrical manner about the center line of the handle 1. The cutting parts are provided with a first cutting edge 3 and a second cutting edge 4. The first cutting edge 3 is located on the periphery of the cutting part, and the second cutting edge 4 is located at the top of the cutting part. Among them, the two first cutting edges 3 are used for processing the mortise and tenon structure, and the two second cutting edges 4 are set in a "V" shape and are used for pattern carving.

[0015] In this technical solution, the cutting part is provided with an integral first cutting edge 3 and a second cutting edge 4. The structure and shape of the first cutting edge 3 are the same as the cutting edge of the existing 45-degree tenon and mortise knife, while the second cutting edge 4 is located at the top of the cutting part, and the two second cutting edges 4 are integrally connected to form a "V" shape. When using this 45-degree tenon and mortise knife, the handle 1 is clamped and fixed by a clamp and driven to rotate, which in turn drives the knife body 2 to rotate. When it is necessary to process mortise and tenon structures, the circumference of the knife body 2 is used to cut the wood. When it is necessary to carve patterns, the top of the knife body 2 is used to cut the wood, so that the 45-degree tenon and mortise knife has multiple cutting functions.

[0016] In summary, by setting a first cutting edge 3 and a second cutting edge 4 on the blade body 2 of the 45-degree tenon and mortise knife, the first cutting edge 3 can cut the wood into tenon and mortise structures, while the second cutting edge 4 can be used for pattern carving on the wood surface.
