[0019] Reference Figure 1-7 The present specific implementation adopts the following technical scheme: a multifunctional knife sharpener, comprising a knife sharpening grip 1, a first knife sharpening portion 2, a second knife sharpening portion 3, a V-shaped triangular piece 4, a pressing handle 5, a triangular file 6, a file fixing nut 7 and a guide rail 8, the front end of the knife sharpening grip 1 is provided with the first knife sharpening portion 2, the knife sharpening grip 1 and the first knife sharpening portion 2 are integrally formed, and the second knife sharpening portion 3 is fixedly installed on the first knife sharpening portion 2 by a screw 9; the knife sharpening grip 1 A pressing handle 5 is formed on the upper edge, and a guide rail 8 and a stop column 16 are provided at the lower part of the inner side surface of the sharpening grip portion 1, and a space for installing a triangular file 6 is formed between the guide rail 8 and the stop column 16. The first sharpening portion 2 and the second sharpening portion 3 are both embedded with a V-shaped triangular piece 4, and a space for sharpening the tool is formed between the two V-shaped triangular pieces 4. A V-shaped notch 14 for the tool to move is provided on the outer side surface of the first sharpening portion 2 corresponding to the V-shaped triangular piece 4, and a file fixing nut 7 for fixing the triangular file 6 is installed at the connection between the first sharpening portion 2 and the front section of the second sharpening portion 3.

[0020] It is worth noting that the triangular file 6 is composed of a file tip 601 at the front end, a triangular file part 602 in the middle and a push-pull twist 603 at the tail end. The file tip 601 and the triangular file part 602 are integrally formed, and the push-pull twist 603 is fixed to the tail end of the triangular file part 602 by threaded connection. The outer side surface of the push-pull twist 603 is a circle of anti-slip grooves 604 for easy pushing and pulling operations.

[0021] It is worth noting that the pressing handle 5 is a handle structure with a straight line section in the middle and arc chamfers at both ends, which can improve the aesthetics and comfort of the knife sharpener and enhance safety.

[0022] In addition, a hanging hole 15 is provided at the rear side of the upper end of the knife sharpening grip 1, and the hanging hole 15 is convenient for hanging the knife sharpener.

[0023] The present specific embodiment comprises a sharpening grip 1, a first sharpening part 2 and a second sharpening part 3 forming the main body of the sharpener, wherein the front end of the second sharpening part 3 is provided with a file nut mounting part 10 protruding from the inner side of the main body of the sharpening part, the file nut mounting part 10 and the second sharpening part 3 are integrated, the front end of the first sharpening part 2 is provided with a mounting position 11 matching the file nut mounting part 10, and the second sharpening part 3 is fixedly mounted on the mounting position 11 of the first sharpening part 2 by a screw 9 during use.
