[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not used to limit the utility model.

[0021] A sharpener, referring to Figs. 1-3, comprises a handle 1 and a rotating disc 2, the rotating disc 2 is two and respectively rotatably arranged at both ends of the handle 1, step holes 201 of outer narrow and inner wide are symmetrically arranged on both sides of the rotating disc 2, the wide hole part of the step hole 201 is embedded with a suction magnet 7; it also comprises a mounting disc 5, which is two and respectively arranged on the apart side of the two rotating discs 2, the outer wall of the mounting disc 5 is provided with a sharpening block 4, the inner end of the mounting disc 5 is detachably installed with a cylindrical magnet 6 which is adaptively inserted into the narrow hole part of the step hole 201, and the cylindrical magnet 6 can be magnetically attracted to the suction magnet 7, used to limit the position of the mounting disc 5 on the rotating disc 2, through the cooperation of the cylindrical magnet 6 and the suction magnet 7, the mounting disc 5 can be magnetically attracted and fixed on one side of the rotating disc 2, at the same time, the installation position of the mounting disc can also be limited through the cooperation of the cylindrical magnet 6 and the step hole 20, avoiding the deviation of the sharpening block 4 when sharpening back and forth, so as to ensure the subsequent sharpening effect, when it is necessary to replace the sharpening block 4, the mounting disc 5 can be directly pulled out from the rotating disc 2 with a little force, and the sharpening part can be replaced, and it can be directly inserted when installing, which is more convenient to install and disassemble while ensuring the installation strength.

[0022] Among them, the advantage of the step hole is that it can assist in limiting the installation position of the suction magnet 7, which can avoid the suction magnet 7 from moving out with the cylindrical magnet 6 when replacing the sharpening block 4.

[0023] It should be mentioned that the sharpener also comprises a base part (not shown in the figure, which can be known from the comparison file), since the main problem solved by the utility model is the replacement of the sharpening part, therefore the structure of the base part will not be described in detail.

[0024] Referring to Figs. 2 and 3, the outer end of the cylindrical magnet 6 is integrally provided with a screw part 601, the inner end of the mounting disc 5 is provided with a threaded hole which is adapted to the screw part 601, the above design can detach the cylindrical magnet 6 from the mounting disc 5, when it is necessary to replace the mounting disc 5, the cylindrical magnet 6 can be detached and installed in the new mounting disc 5, which can reduce the overall replacement cost.

[0025] Further, the anti-skid ring 3 is sleeved on the outer circumferential side of the rotating disc 2. The anti-skid ring 3 can ensure sufficient friction with the placement plane during the sharpening of the knife, thereby driving the sharpening part to rotate, making the sharpening more uniform, and can also lift the sharpening part to separate it from the placement plane, preventing the sharpening part from scratching the placement plane and avoiding the corrosion of the sharpening part by some wet objects or corrosive objects on the placement plane. In addition, the anti-skid ring 3 can also have certain shock resistance when the sharpening assembly is impacted, thereby improving the service life of the sharpening part.

[0026] Optionally, the anti-skid ring 3 can be a silica gel ring, a rubber ring or other materials, which are not limited here.

[0027] Further, the bearing 9 is sleeved on the outer circumferential side of the guide column 102, the inner end of the rotating disc 2 is connected to the rotating part of the bearing 9, and the screw 8 is integrally provided with a pressing plate. The guide column 102 has a second threaded hole matched with the screw 8. When the screw 8 is installed on the second threaded hole, the pressing plate presses the fixed part of the bearing 9 on the guide column 102. Through the cooperation of the rotating disc 2 and the bearing 9, the rotating disc 2 and the mounting disc 5 can rotate relative to the handle 1, so that the sharpening of the sharpening block 4 is more uniform and complete, thereby improving the sharpening effect and saving the user's effort during sharpening, which has high practicability.

[0028] Further, the sharpening block 4 is embedded on the outer wall of the mounting disc 5 in a semi-exposed state, which can ensure the contact area between the sharpening block 4 and the knife, thereby enabling the sharpening operation on the knife part. The sharpening block 4 is preferably made of diamond sand material, which is not limited here.

[0029] Further, the mounting disc 5 is provided with a through hole 501 in the center, which does not interfere with the screw 8. In some use scenarios, such as the use of double-sided adhesive tape or other detachable methods to fix the sharpening block 4 and the mounting disc 5, the through hole 501 can also facilitate the removal of the sharpening block 4 from the mounting disc 5 for replacement.

[0030] Further, the middle part of the handle 1 is inwardly recessed to form a holding groove 101, which can facilitate the user's holding and reduce the overall weight, thereby facilitating the user's use.

[0031] The handle 1 can be made of wood or other materials, which are not limited here.

[0032] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
