[0027] As shown in Figures 1 to 5 , the present application provides a rotating knife sharpening device, comprising: a knife sharpening device body 100, including a roller 10, a shaft sleeve 20, a bearing 40, a knife sharpening stone support 50, a fixed cover 60, a first knife sharpening stone 80 and a second knife sharpening stone 90, the shaft sleeve 20 is located outside the roller 10, the bearing 40 is sleeved outside the shaft sleeve 20, and the bearing 40 is clamped inside the knife sharpening stone support 50; the outer ring of the knife sharpening stone support 50 is provided with a placing groove 51, and the inner side of the knife sharpening stone support 50 is provided with an adaptive groove 52, and the adaptive groove 52 is adapted between the hexagonal groove 62.

[0028] ​​According to the above technical scheme, since the shaft sleeve 20 is located outside the roller 10, during installation of the shaft sleeve 20, the shaft sleeve 20 can be clamped into the clamping groove 11 on one side of the roller 10, so that the shaft sleeve 20 and the clamping groove 11 are connected through the installation screw 30 inserted into the insertion hole 22, and the end of the installation screw 30 is connected with the threaded groove, so that the installation screw 30 fixes the shaft sleeve 20 in the clamping groove 11. Similarly, the other group of shaft sleeves 20 are also fixed in the above manner. Then, the bearing 40 is sleeved outside the shaft sleeve 20 and close to the end. Then, the inner side of the knife-sharpening stone support 50 is sleeved with the outer ring of the bearing 40, so that the knife-sharpening stone support 50 is preliminarily installed. Then, the outer thread 61 on one side of the fixing cover 60 is rotationally connected with the inner side of the inner thread 21, and the inner hexagonal tool is connected with the hexagonal groove 62 until the fixing cover 60 is attached to the matching groove 52, so that the fixing cover 60 is installed in place, and the knife-sharpening stone support 50 is locked outside the bearing 40 by the fixing cover 60, so that the knife-sharpening stone support 50 is prevented from falling off. The rolling silica gel ring 70 is sleeved in the placement groove 51, and finally the first knife-sharpening stone 80 and the second knife-sharpening stone 90 are connected to the inner sides of the two groups of protective rings 53 through the adhesive layer, so that the first knife-sharpening stone 80 and the second knife-sharpening stone 90 are fixed.

[0029] It should be noted that during use of the knife-sharpening device main body 100, the cutting edge of the knife is upwardly clamped by an auxiliary tool. The product is close to the cutting edge and holds the roller 10 to roll back and forth for grinding. The rotation principle is to press the roller 10 to rotate, and the shaft sleeve 20 fixed on the roller 10 is transmitted to the bearing 40 and the knife-sharpening stone support 50 to roll, so that the first knife-sharpening stone 80 and the second knife-sharpening stone 90 coarsely / finely grind the cutting edge. This can solve the problem of single coarse grinding stone or fine grinding stone step-by-step operation, and the user needs to frequently replace different mesh grinding stones, which increases the time cost. Especially in outdoor scenes, it is extremely inconvenient to carry multiple grinding stones, and the split structure cannot guarantee the continuity of coarse grinding and fine grinding, the cutting edge angle is easy to deviate, and the efficiency is low.

[0030] In an optional embodiment, the two sides of the roller 10 are provided with clamping grooves 11 matched with the shaft sleeves 20, so that the shaft sleeves 20 can be conveniently placed and fixed in the clamping grooves 11.

[0034] In an optional embodiment, the number of the grinding stone holder 50 is two groups and is symmetrically distributed on both sides of the roller 10. The outer side of the two groups of grinding stone holders 50 is integrally connected with the protective ring 53 matched with the grinding stone one 80 and the grinding stone two 90, which facilitates the limiting support of the grinding stone one 80 and the grinding stone two 90, and the grinding stone one 80 and the grinding stone two 90 are installed and positioned. At the same time, the grinding stone one 80 and the grinding stone two 90 are two groups of grinding stones with different mesh numbers, and any one group of the grinding stone one 80 and the grinding stone two 90 can be coarse grinding stone or fine grinding stone.

[0035] In an optional embodiment, the grinding stone one 80 and the grinding stone two 90 are provided with an adhesive layer at the connection with the grinding stone holder 50, which facilitates the installation and fixation of the grinding stone one 80 and the grinding stone two 90. The adhesive layer can be glue, double-sided tape and other adhesive materials that can connect and fix the grinding stone one 80 and the grinding stone two 90.

[0036] In an optional embodiment, the outer side of the fixed cover 60 is engraved with an external thread 61 matched with the internal thread 21. The fixed cover 60 and the shaft sleeve 20 are threadedly connected through the external thread 61 along the inner side of the internal thread 21, which has high matching degree and convenient operation, and can limit the grinding stone holder 50 to prevent the grinding stone holder 50 from falling off.

[0037] In an optional embodiment, the outer side of the placing groove 51 is matched with the rolling silica gel ring 70, and the number of the rolling silica gel ring 70 is two groups and is symmetrically distributed, which facilitates the installation of the rolling silica gel ring 70. The rolling silica gel ring 70 can be rolled along the desktop, and then the grinding stone holder 50 is rolled, and the grinding stone one 80 or the grinding stone two 90 is rolled under the support of the bearing 40, and the grinding operation of the grinding stone one 80 and the grinding stone two 90 is completed.
