[0021] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a knife sharpener 100, comprising a rolling bracket 1 and a first knife sharpening member 2 and a second knife sharpening member 3 respectively arranged at two ends of the rolling bracket 1, the rolling bracket 1 comprises a roller 11, a first turntable 12 arranged between the first knife sharpening member 2 and the roller 11, and a second turntable 13 arranged between the second knife sharpening member 3 and the roller 11, the first knife sharpening member 2 is coupled to the first turntable 12 and performs a circular motion when the roller 11 rolls, and the second knife sharpening member 3 is coupled to the second turntable 13 and does not perform a circular motion when the roller 11 rolls.

[0024] Specifically, the drum 11 includes a boss 111 connected to the first rotating disk 12 and an annular member 112 connected to the second rotating disk 13, the boss 111 includes a slot 110, the first rotating disk 12 includes an annular ring 120 and a protrusion 121 protruding inward from the annular ring 120 and engaging with the slot 110, the boss 111 is received in the annular ring 120, and the second rotating disk 13 includes a convex column 131 received in the annular member 112. The first grinding member 2 is connected to the first rotating disk 12 by magnetic attraction, the boss 111 is provided with a slot for receiving a magnet, and the second grinding member 3 is connected to the second rotating disk 13 by magnetic attraction, and the second rotating disk 13 is provided with a slot for receiving a magnet. When the drum 11 rolls, the first grinding member 2 is adsorbed on the boss 111 and moves with the drum 11, that is, it moves in a circular motion while moving in a translation, and the second grinding member 3 only moves in a translation but not in a circular motion. In this way, the first sharpening member 2 and the second sharpening member 3 have different movement modes, so that the sharpener 100 can be adapted to different sharpening requirements.

[0025] Furthermore, the knife sharpener 100 also includes a first rubber ring 4 arranged around the first turntable 12 and a second rubber ring 5 arranged around the second turntable 13. The first rubber ring 4 and the second rubber ring 5 can enable the first turntable 12 and the second turntable 13 to roll relative to the table surface better with the roller 11, thereby preventing the first turntable 12 and the second turntable 13 from slipping and affecting the grinding effect of the knife blade.

[0026] Preferably, the diameter of the end of the drum 11 close to the first rotating disk 12 is different from the diameter of the end of the drum 11 close to the second rotating disk 13. In this embodiment, the diameter of the end of the drum 11 close to the first rotating disk 12 is larger than the diameter of the end of the drum 11 close to the second rotating disk 13, which makes it easier for users to distinguish between two sharpening members with different movement modes. The diameter of the middle part of the drum 11 is smaller than the diameter of the end of the drum 11 close to the second rotating disk 13, which makes it easier for users to pick up the drum 11.

[0027] The knife sharpener provided by the utility model comprises a rolling bracket and a first knife sharpening member and a second knife sharpening member respectively arranged at two ends of the rolling bracket, the rolling bracket comprises a roller, a first rotating disk arranged between the first knife sharpening member and the roller, and a second rotating disk arranged between the second knife sharpening member and the roller, the first knife sharpening member is coupled to the first rotating disk and performs a circular motion when the roller rolls, and the second knife sharpening member is coupled to the second rotating disk and does not perform a circular motion when the roller rolls. The rolling knife sharpener is small in size and compact in structure, and because the first knife sharpening member and the second knife sharpening member move in different ways when the roller rolls, the knife sharpener can be suitable for different knife sharpening needs.

[0028] The utility model also provides a knife sharpening base 200, comprising a first base 21 and a second base 22 that are engaged with each other, wherein the first base 21 has an inclined positioning surface 20. The angle between the positioning surface 20 and a surface of the second base 22 that is away from the first base 21 is an acute angle. In this embodiment, the length of the first base 21 is greater than the length of the second base 22, and the width of the first base 21 is less than the width of the second base 22.

[0029] The utility model provides a knife sharpening base, which includes a first base and a second base that are engaged with each other, wherein the first base has an inclined positioning surface. The knife sharpening base is used in conjunction with a knife sharpener, and the positioning surface is used to fix the knife so that the knife sharpener can grind the knife. Since the knife sharpening base includes the first base and the second base that are engaged with each other, the knife sharpening base can be placed on the front side or on the back side, and is suitable for knives of different shapes.

[0030] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
